Calculation of Reduction Ratio in a Cycloidal Gearbox
The reduction ratio in a cycloidal gearbox can be calculated using the following formula:
Reduction Ratio = (Number of Input Pins + Number of Output Pins) / Number of Output Pins
In a cycloidal gearbox, the input pins engage with the lobes of the cam disc, while the output pins are engaged with the cycloidal pins of the output rotor. The reduction ratio determines the relationship between the number of input and output pins engaged at any given time.
For example, if a cycloidal gearbox has 7 input pins and 14 output pins engaged, the reduction ratio would be:
Reduction Ratio = (7 + 14) / 14 = 1.5
This means that for every 1 revolution of the input pins, the output rotor will complete 1.5 revolutions. The reduction ratio is a key parameter that influences the output speed and torque of the cycloidal gearbox.

Suitability of Cycloidal Gearboxes for High-Torque Applications
Cycloidal gearboxes are well-suited for high-torque applications due to their unique design and mechanical advantages. Here’s why they are suitable:
- Multiple Engagement Points: Cycloidal gearboxes have multiple teeth in contact at any given moment, distributing the load over a larger area. This reduces wear and stress on individual teeth, making them capable of handling high torque.
- High Load-Carrying Capacity: The design of the cycloidal mechanism, with its large number of pins and rollers, provides high load-carrying capacity. This makes them capable of transmitting significant torque without failure.
- Tight Tolerances: The precision and tight tolerances in the construction of cycloidal gearboxes ensure smooth and efficient power transmission even under heavy loads.
- Compact Design: Cycloidal gearboxes achieve high torque in a relatively compact size. This is particularly advantageous in applications where space is limited.
- High Gear Ratio: Cycloidal gearboxes can achieve high gear ratios, allowing them to convert lower input speeds into higher output torque, which is essential in high-torque applications.
These factors make cycloidal gearboxes a reliable choice for various high-torque applications across industries such as heavy machinery, robotics, material handling, and more.
Noise and Vibration Considerations in Cycloidal Gearboxes
Cycloidal gearboxes are generally known for their smooth and quiet operation. However, like any mechanical system, they can still exhibit some level of noise and vibration. Here are the key factors to consider:
- Gear Design: The unique rolling contact design of cycloidal gears contributes to their relatively low noise levels. The teeth engagement is gradual and continuous, reducing impact forces and noise.
- Lubrication: Proper lubrication is essential to minimize friction and noise. Using high-quality lubricants and maintaining proper lubrication levels can help reduce noise and vibration in cycloidal gearboxes.
- Precision Manufacturing: Precise manufacturing processes and tight tolerances can help minimize irregularities in gear meshing, which can contribute to noise and vibration.
- Load Distribution: Proper load distribution among multiple lobes in the cycloidal mechanism can help prevent localized stress concentrations that could lead to vibrations and noise.
- Bearing Quality: High-quality bearings can contribute to smooth operation and reduce vibrations that could be transmitted to the gearbox housing.
- Mounting and Installation: Proper mounting and alignment of the gearbox are important to ensure that it operates smoothly and without excessive vibrations.
While cycloidal gearboxes are designed to minimize noise and vibration, it’s important to consider the specific application, environmental conditions, and operating parameters. Regular maintenance, proper lubrication, and selecting the appropriate gearbox size and type can all contribute to reducing noise and vibration levels in cycloidal gearboxes.
Disadvantages of Using a Cycloidal Gearbox
While cycloidal gearboxes offer various advantages, they also come with some disadvantages that should be considered:
- Lower Efficiency at High Speeds: Cycloidal gearboxes can experience a decrease in efficiency at high speeds due to increased friction and rolling resistance.
- Complex Design: The internal arrangement of pins, lobes, and bearings can result in a relatively complex design, which may lead to higher manufacturing costs and maintenance challenges.
- Limited Gear Ratio Range: Cycloidal gearboxes might have limitations in terms of achieving very high gear ratios, which can impact their suitability for certain applications.
- Cost: The specialized design and precision manufacturing involved in producing cycloidal gearboxes can lead to higher upfront costs compared to other gearbox types.
- Noise Generation: While generally quieter than some other types of gearboxes, cycloidal gearboxes can still produce noise during operation, which might need to be addressed in noise-sensitive applications.
- Availability: Cycloidal gearboxes might not be as widely available as other gearbox types, potentially leading to longer lead times for procurement and replacement parts.
- Limited Backlash Adjustability: While cycloidal gearboxes have minimal backlash, adjusting or fine-tuning the backlash might be more challenging compared to other gearbox types.
Despite these disadvantages, cycloidal gearboxes remain a valuable choice for specific applications where their unique advantages outweigh the drawbacks.

Calculation of Reduction Ratio in a Cycloidal Gearbox
The reduction ratio in a cycloidal gearbox can be calculated using the following formula:
Reduction Ratio = (Number of Input Pins + Number of Output Pins) / Number of Output Pins
In a cycloidal gearbox, the input pins engage with the lobes of the cam disc, while the output pins are engaged with the cycloidal pins of the output rotor. The reduction ratio determines the relationship between the number of input and output pins engaged at any given time.
For example, if a cycloidal gearbox has 7 input pins and 14 output pins engaged, the reduction ratio would be:
Reduction Ratio = (7 + 14) / 14 = 1.5
This means that for every 1 revolution of the input pins, the output rotor will complete 1.5 revolutions. The reduction ratio is a key parameter that influences the output speed and torque of the cycloidal gearbox.

ts: the input disc and the output disc.
The input disc has lobes with pins, while the output disc has lobes with matching holes. The lobes on both discs are not perfectly circular but are shaped in a cycloidal profile. As the input disc rotates, the pins on its lobes engage with the holes in the output disc’s lobes.
As the input disc rotates, the pins move along the cycloidal paths, causing the output disc to rotate. The interaction between the pins and the holes results in smooth and cont
Distinguishing Features of Cycloidal Gearboxes
Cycloidal gearboxes, also known as cycloidal drives or cycloidal reducers, possess distinct characteristics that set them apart from other types of gearboxes:
- Principle of Operation: Cycloidal gearboxes utilize the principle of cycloidal motion, where input shaft movement is transformed into eccentric motion of the cycloidal disc. This unique mechanism results in smooth and consistent output motion.
- Compactness: Cycloidal gearboxes are renowned for their compact size and high torque density. The concentric design of the components contributes to their ability to transmit substantial torque in a relatively small package.
- Tooth Profile: Cycloidal gearboxes employ specialized cycloidal teeth, which involve both pinwheel and roller gears. This distinctive tooth profile contributes to the characteristic smooth and vibration-free operation.
- Reduction Mechanism: They often employ multi-lobed cam gears that interact with the pins on the cycloidal disc, resulting in multiple gear engagements per revolution and improved load distribution.
- Motion Control: Cycloidal gearboxes offer high positional accuracy and motion control due to the eccentric motion of the disc, making them suitable for robotics, automation, and precision applications.

- Applications: Cycloidal gearboxes are commonly used in various industries, including robotics, packaging, material handling, printing, and more, where their compactness, precision, and efficiency are valued.
These distinguishing features contribute to the unique capabilities and benefits of cycloidal gearboxes in specific applications.
inuous motion transfer. The unique shape of the cycloidal profile ensures that there is always at least one point of contact between the pins and the holes, allowing for efficient torque transmission and reduced wear.
Cycloidal gearing provides advantages such as high torque capacity, compact size, and precision motion. However, due to the complex shape of the components and the continuous engagement, manufacturing and assembly of cycloidal gearboxes can be intricate.

Disadvantages of Using a Cycloidal Gearbox
While cycloidal gearboxes offer various advantages, they also come with some disadvantages that should be considered:
- Lower Efficiency at High Speeds: Cycloidal gearboxes can experience a decrease in efficiency at high speeds due to increased friction and rolling resistance.
- Complex Design: The internal arrangement of pins, lobes, and bearings can result in a relatively complex design, which may lead to higher manufacturing costs and maintenance challenges.
- Limited Gear Ratio Range: Cycloidal gearboxes might have limitations in terms of achieving very high gear ratios, which can impact their suitability for certain applications.
- Cost: The specialized design and precision manufacturing involved in producing cycloidal gearboxes can lead to higher upfront costs compared to other gearbox types.
- Noise Generation: While generally quieter than some other types of gearboxes, cycloidal gearboxes can still produce noise during operation, which might need to be addressed in noise-sensitive applications.
- Availability: Cycloidal gearboxes might not be as widely available as other gearbox types, potentially leading to longer lead times for procurement and replacement parts.
- Limited Backlash Adjustability: While cycloidal gearboxes have minimal backlash, adjusting or fine-tuning the backlash might be more challenging compared to other gearbox types.
Despite these disadvantages, cycloidal gearboxes remain a valuable choice for specific applications where their unique advantages outweigh the drawbacks.

Developing a Mathematical Model of a Cyclone Gearbox
Compared to planetary gearboxes, cycloidal gearboxes are often seen as the ideal choice for a wide range of applications. They feature compact designs that are often low friction and high reduction ratios.
Low friction
Developing a mathematical model of a cycloidal gearbox was a challenge. The model was able to show the effects of a variety of geometric parameters on contact stresses. It was able to model stiction in all quadrants. It was able to show a clear correlation between the results from simulation and real-world measurements.
The model is based on a new approach that enables modeling stiction in all quadrants of a gearbox. It is also able to display non-zero current at standstill. Combined with a good simulation algorithm, the model can be used to improve the dynamic behaviour of a controlled system.
A cycloidal gearbox is a compact actuator used for industrial automation. This type of gearbox provides high gear ratios, low wear, and good torsional stiffness. In addition, it has good shock load capacity.
The model is based on cycloidal discs that engage with pins on a stationary ring gear. The resulting friction function occurs when the rotor begins to rotate. It also occurs when the rotor reverses its rotation. The model has two curves, one for motor and one for generator mode.
The trochoidal profile on the cycloidal disc’s periphery is required for proper mating of the rotating parts. In addition, the profile should be defined accurately. This will allow an even distribution of contact forces.
The model was used to compare the relative performance of a cycloidal gearbox with that of an involute gearbox. This comparison indicates that the cycloidal gearbox can withstand more load than an involute gearbox. It is also able to last longer. It is also able to produce high gear ratios in a small space.
The model used is able to capture the exact geometry of the parts. It can also allow a better analysis of stresses.
Compact
Unlike helical gearing, compact cycloidal gearboxes can provide higher reduction ratios. They are more compact and less weighty. In addition, they provide better positioning accuracy.
Cycloid drives provide high torque and load capacity. They are also very efficient and robust. They are ideal for applications with heavy loads or shock loads. They also feature low backlash and high torsional stiffness. Cycloid gearboxes are available in a variety of designs.
Cycloid discs are mounted on an eccentric input shaft, which drives them around a stationary ring gear. The ring gear consists of many pins, and the cycloidal disc moves one lobe for every rotation of the input shaft. The output shaft contains roller pins, which rotate around holes in the cycloidal disc.
Cycloid drives are ideally suited to heavy loads and shock loads. They have high torsional stiffness and high reduction ratios, making them very efficient. Cycloid gearboxes have low backlash and high torque and are very compact.
Cycloid gearboxes are used for a wide variety of applications, including marine propulsion systems, CNC machining centers, medical technology, and manipulation robots. They are especially useful in applications with critical positioning accuracy, such as surgical positioning systems. Cycloid gearboxes feature extremely low hysteresis loss and low backlash over extended periods of use.
Cycloid discs are usually designed with a reduced cycloid diameter to minimize unbalance forces at high speeds. Cycloid drives also feature minimal backlash, a high reduction ratio, and excellent positioning accuracy. Cycloid gearboxes also have a long service life, compared to other gear drives. Cycloid drives are highly robust, and offer higher reduction ratios than helical gear drives.
Cycloid gearboxes have a low cost and are easy to print. CZPT gearboxes are available in a wide range of sizes and can produce high torque on the output axis.
High reduction ratio
Among the types of gearboxes available, a high reduction ratio cycloidal gearbox is a popular choice in the automation field. This gearbox is used in applications requiring precise output and high efficiency.
Cycloid gears can provide high torque and transmit it well. They have low friction and a small backlash. They are widely used in robotic joints. However, they require special tools to manufacture. Some have even been 3D printed.
A cycloidal gearbox is typically a three-stage structure that includes an input hub, an output hub, and two cycloidal gears that rotate around each other. The input hub mounts movable pins and rollers, while the output hub mounts a stationary ring gear.
The input shaft is driven by an eccentric bearing. The disc is then pushed against the ring gear, which causes it to rotate around the bearing. As the disc rotates, the pins on the ring gear drive the pins on the output shaft.
The input shaft rotates a maximum of nine revolutions, while the output shaft rotates three revolutions. This means that the input shaft has to rotate over eleven million times before the output shaft is able to rotate. The output shaft also rotates in the opposite direction of the input shaft.
In a two-stage differential cycloidal speed reducer, the input shaft uses a crank shaft design. The crank shaft connects the first and second cycloidal gears and actuates them simultaneously.
The first stage is a cycloidal disc, which is a gear tooth profile. It has n=7 lobes on its circumference. Each lobe moves around a reference pitch circle of pins. The disc then advances in 360deg steps.
The second stage is a cycloidal disc, also known as a “grinder gear”. The teeth on the outer gear are fewer than the teeth on the inner gear. This allows the gear to be geardown based on the number of teeth.
Kinematics
Various scholars have studied the kinematics of cycloidal gearbox. They have developed various approaches to modify the tooth profile of cycloidal gears. Some of these approaches involve changing the shape of the cycloidal disc, and changing the grinding wheel center position.
This paper describes a new approach to cycloid gear profile modification. It is based on a mathematical model and incorporates several important parameters such as pressure angle, backlash, and root clearance. The study offers a new way for modification design of cycloid gears in precision reducers for robots.
The pressure angle of a tooth profile is an intersegment angle between the normal direction and the velocity direction at a meshing point. The pressure angle distribution is important for determining force transmission performance of gear teeth in meshing. The distribution trend can be obtained by calculating the equation (5).
The mathematical model for modification of the tooth profile can be obtained by establishing the relationship between the pressure angle distribution and the modification function. The dependent variable is the modification DL and the independent variable is the pressure angle a.
The position of the reference point A is a major consideration in the modification design. It ensures the force transmission performance of the meshing segment is optimal. It is determined by the smallest profile pressure angle. The position is also dependent on the type of gear that is being modified. It is also influenced by the tooth backlash.
The mathematical model governing the pressure angle distribution is developed with DL=f(a). It is a piecewise function that determines the pressure angle distribution of a tooth profile. It can also be expressed as DL=ph.
The pressure angle of a tooth is also an angle between the common normal direction at the meshing point and the rotation velocity direction of the cycloid gear.
Planetary gearboxes vs cycloidal gearboxes
Generally, there are two types of gearboxes that are used for motion control applications: cycloidal gearbox and planetary gearbox. Cycloid gearboxes are used for high-frequency motions, while planetary gearboxes are suitable for low-speed applications. Both are highly accurate and precise gearboxes that are capable of handling heavy loads at high cycle rates. But they have different advantages and disadvantages. So, engineers need to determine which type of gearbox is best suited for their application.
Cycloid gearboxes are commonly used in industrial automation. They provide excellent performance with ratios as low as 10:1. They offer a more compact design, higher torque density and greater overload protection. They also require less space and are less expensive than planetary gearboxes.
On the other hand, planetary gearboxes are lightweight and offer a higher torque density. They are also capable of handling higher ratios. They have a longer life span and are more precise and durable. They can be found in a variety of styles, including square-framed, round-framed and double-frame designs. They offer a wide range of torque and speed capabilities and are used for numerous applications.
Cycloid gearboxes can be manufactured with different types of cycloidal cams, including single or compound cycloidal cams. Cycloid cams are cylindrical elements that have cam followers that rotate in an eccentric fashion. The cam followers act like teeth on the internal gear. Cycloid cams are a simple concept, but they have numerous advantages. They have a low backlash over extended periods of time, allowing for more accurate positioning. They also have internal compressive stresses and an overlap factor between the rolling elements.
Planetary gearboxes are characterized by three basic force-transmitting elements: ring gear, sun gear, and planet gear. They are generally two-stage gearboxes. The sun gear is attached to the input shaft, which in turn is attached to the servomotor. The ring gear turns the sun gear and the planet gear turns the output shaft.

The Basics of a Cyclone Gearbox
Besides being compact, cycloidal speed reducers also offer low backlash and high ratios. Because of the small size of the drive, they are ideal for applications where space is a problem.
Involute gear tooth profile
Almost all gears use an involute gear tooth profile. This profile has a single curve, which means that the gear teeth do not have to be aligned closely with each other. This profile is smooth and can be manufactured easily.
Cycloid gears have a combination of epicycloid and hypocycloid curves. This makes them stronger than involute gear teeth. However, they can be more expensive to manufacture. They also have larger reduction ratios. They transmit more power than involute gears. Cycloid gears can be found in clocks.
When designing a gear, you need to consider several factors. Some of these include the number of teeth, the tooth angle and the lubrication type. Having a gear tooth that is not perfectly aligned can result in transmission error, noise and vibration.
The tooth profile of an involute gear is usually considered the best. Because of this, it is used in a wide variety of gears. Some of the most common applications for this profile are power transmission gears. However, this profile is not the best for every application.
Cycloid gears require more complex manufacturing processes than involute gear teeth. This can cause a larger tooth cost. Cycloid gears are used for less noisy applications.
Cycloid gears also transmit more power than involute gears. This can cause problems if the radii change tangentially. However, the shape is more simple than involute gears. Involute gears can handle centre sifts better.
Cycloid gears are less susceptible to transmission error. Cycloid gears have a convex surface, which makes them stronger than involute teeth. Cycloid gears also have a larger reduction ratio than involute gears. Cycloid teeth do not interfere with the mating teeth. However, they have a smaller number of teeth than involute teeth.
Rotation on the inside of the reference pitch circle of the pins
Whether a cycloidal gearbox is designed for stationary or rotating applications, the fundamental law of gearing must be observed: The ratio of angular velocities must be constant. This requires the rotation on the inside of the reference pitch circle of the pins to be constant. This is achieved through a series of cycloidal teeth, which act like tiny levers to transmit motion.
A cycloidal disc has N lobes which are rotated by three lobes per rotation around N pins. The number of lobes on a cycloidal disc is a significant factor in determining the transmission ratio.
A cycloidal disc is driven by an eccentric input shaft which is mounted to an eccentric bearing within an output shaft. As the input shaft rotates, the cycloidal disc moves around the pins of the pin disc.
The drive pin rotates at a 40 deg angle while the cycloidal disc rotates on the inside of the reference pitch circle of pins. As the drive pin rotates, it will slow the output motion. This means that the output shaft will complete only three revolutions with the input shaft, as opposed to nine revolutions with the input shaft.
The number of teeth on a cycloidal disc must be small compared to the number of surrounding pins. The disc must also be constructed with an eccentric radius. This will determine the size of the hole which will be required for the pin to fit between the pins.
When the input shaft is turned, the cycloidal disc will rotate on the inside of the reference pitch circle of roller pins. This will then transmit motion to the output shaft. The output shaft is supported by two bearings in an output housing. This design has low wear and torsional stiffness.
Transmission ratio
Choosing the right transmission ratio of cycloidal gearbox isn’t always easy. You might need to know the size of your gearbox before you can make an educated choice. You may also need to refer to the product catalog for guidance. For example, CZPT gearboxes have some unique ratios.
A cycloidal gear reducer is a compact and high-speed torque transmission device that reverses the direction of angular movement of the follower shaft. It consists of an eccentric cam positioned inside a cycloidal disc. Pin rollers on the follower shaft fit into matching holes in the cycloidal disc. In the process, the pins slide around the holes, in response to wobbling motion. The cycloidal disc is also capable of engaging the internal teeth of a ring-gear housing.
A cycloidal gear reducer can be used in a wide variety of applications, including industrial automation, robotics and power transmissions on boats and cranes. A cycloidal gear reducer is ideally suited for heavy duty applications with large payloads. They require specialized manufacturing processes, and are often used in equipment with precise output and high efficiency.
The cycloidal gear reducer is a relatively simple structure, but it does require some special tools. Cycloid gear reducers are also used to transmit torque, which is one of the reasons they are so popular in automation. Using a cycloidal gear reducer is a good choice for applications that require higher efficiency and lower backlash. It is also a good choice for applications where size is a concern. Cycloid gears are also a good choice for applications where high speed and high torque are required.
The transmission ratio of cycloidal gearbox is probably the most important function of a gearbox. You need to know the size of your gearbox and the type of gears it contains in order to make the right choice.

Considering the unique dynamics of a cycloidal gearbox, vibration reduction measures are required for a smooth operation. These measures can also help with the detection of faults.
A cycloidal gearbox is a gearbox with an eccentric bearing that rotates the center of the gears. It shares torque load with five outer rollers at any given time. It can be applied in many applications. It is a relatively inexpensive asset. However, if it fails, it can have significant economic impacts.
A typical input/output gearbox consists of a ring plate and two cranks mounted on the input shaft. The ring plate rotates when the input shaft rotates. There are two bearings on the output shaft.
The ring plate is a major noise source because it is not balanced. The cycloidal gear also produces noise when it meshes with the ring plate. This noise is generated by structural resonance. Several studies have been performed to solve this problem.
However, there is not much documented work on the condition monitoring of cycloidal gearboxes. In this article, we will introduce modern techniques for vibration diagnostics.
A cycloidal gearbox with a reduced reduction ratio has higher induced stresses in the cycloidal disc. In this case, the size of the output hole is larger and more material is removed from the cycloidal disc. This increase in the disc’s stresses leads to higher vibration amplitudes.
The load distribution along the width of the gear is an important design criterion. Using different gear profiles can help to optimize the transmission of torque. The contact stress of the cycloidal disc can also be investigated.
To determine the amplitude of the noise, the frequency of the gear mesh is multiplied by the shaft rate. If the RPM is relatively stable, the frequency can be used as a measure of magnitude. However, this is only accurate at close to failure.
Comparison with planetary gearboxes
Several differences exist between cycloidal gearboxes and planetary gearboxes. They are related to gear geometry and manufacturing processes. Among them, there are:
– The output shaft of a cycloidal gearbox has a larger torque than the input shaft. The rotational speed of the output shaft is lower than the input shaft.
– The cycloid gear disc rotates at variable velocity, while the planetary gear has a fixed speed. Consequently, the cycloid disc and output flange transmission accuracy is lower than that of the planetary gears.
– The cycloidal gearbox has a larger gripping area than the planetary gear. This is an advantage of the cycloidal gearbox in that it can handle larger loads.
– The cycloid profile has a significant impact on the quality of contact meshing between the tooth surfaces. The width of the contact ellipses increases by 90%. This is a result of the elimination of undercuts of the lobes. In this way, the contact force on the cycloid disc is decreased significantly.
– The cycloid drive has lower backlash and high torsional stiffness. This allows a cycloidal drive to be more stable against shock loads. The cycloid drive is also a compact design, which is ideally suited for applications with large transmission ratios.
– The output hub of the cycloid gearbox has movable pins and rollers. These components are attached to the ring gear in the outer gearbox. The output shaft is also turned by the planet carrier. The output hub of the cycloid system is composed of two parts: the ring gear and the output flange.
– The input shaft of a cycloidal gearbox is connected to a servomotor. The input shaft is a cylindrical element that is fixed to the planet carrier.

The Advantages of Using a Cyclone Gearbox
Using a cycloidal gearbox to drive an input shaft is a very effective way to reduce the speed of a machine. It does this by reducing the speed of the input shaft by a predetermined ratio. It is capable of very high ratios in relatively small sizes.
Transmission ratio
Whether you’re building a marine propulsion system or a pump for the oil and gas industry, there are certain advantages to using cycloidal gearboxes. Compared to other gearbox types, they’re shorter and have better torque density. These gearboxes also offer the best weight and positioning accuracy.
The basic design of a cycloidal gearbox is similar to that of a planetary gearbox. The main difference is in the profile of the gear teeth.
Cycloid gears have less tooth flank wear and lower Hertzian contact stress. They also have lower friction and torsional stiffness. These advantages make them ideal for applications that involve heavy loads or high-speed drives. They’re also good for high gear ratios.
In a cycloidal gearbox, the input shaft drives an eccentric bearing, while the output shaft drives the cycloidal disc. The cycloidal disc rotates around a fixed ring, and the pins of the ring gear engage the holes in the disc. The pins then drive the output shaft as the disc rotates.
Cycloid gears are ideal for applications that require high gear ratios and low friction. They’re also good for applications that require high torsional stiffness and shock load resistance. They’re also suitable for applications that require a compact design and low backlash.
The transmission ratio of a cycloidal gearbox is determined by the number of lobes on the cycloidal disc. The n=n design of the cycloidal disc moves one lobe per revolution of the input shaft.
Cycloid gears can be manufactured to reduce the gear ratio from 30:1 to 300:1. These gears are suitable for high-end applications, especially in the automation industry. They also offer the best positioning accuracy and backlash. However, they require special manufacturing processes and require non-standard characteristics.
Compressive force
Compared with conventional gearboxes, the cycloidal gearbox has a unique set of kinematics. It has an eccentric bearing in a rotating frame, which drives the cycloidal disc. It is characterized by low backlash and torsional stiffness, which enables geared motion.
In this study, the effects of design parameters were investigated to develop the optimal design of a cycloidal reducer. Three main rolling nodes were studied: a cycloidal disc, an outer race and the input shaft. These were used to analyze the motion related dynamic forces, which can be used to calculate stresses and strains. The gear mesh frequency was calculated using a formula, which incorporated a correction factor for the rotating frame of the outer race.
A three-dimensional finite element analysis (FEA) study was conducted to evaluate the cycloidal disc. The effects of the size of the holes on the disc’s induced stresses were investigated. The study also looked at the torque ripple of a cycloidal drive.
The authors of this study also explored backlash distribution in the output mechanism, which took into account the machining deviations and structure and geometry of the output mechanism. The study also looked at the relative efficiency of a cycloidal reducer, which was based on a single disc cycloidal reducer with a one-tooth difference.
The authors of this study were able to deduce the contact stress of the cycloidal disc, which is calculated using the material-based contact stiffness. This can be used to determine accurate contact stresses in a cycloidal gearbox.
It is important to know the ratios needed for calculation of the bearing rate. This can be calculated using the formula f = k (S x R) where S is the volume of the element, R is the mass, k is the contact stiffness and f is the force vector.
Rotational direction
Unlike the conventional ring gear which has a single axis of rotation, cycloidal gearbox has three rotational axes which are parallel and are located in a single plane. A cycloidal gearbox has excellent torsional stiffness and shock load capacity. It also ensures constant angular velocity, and is used in high-speed gearbox applications.
A cycloidal gearbox consists of an input shaft, a drive member and a cycloidal disc. The disc rotates in one direction, while the input shaft rotates in the opposite direction. The input shaft eccentrically mounts to the drive member. The cycloidal disc meshes with the ring-gear housing, and the rotational motion of the cycloidal disc is transferred to the output shaft.
To calculate the rotational direction of a cycloidal gearbox, the cycloid must have the correct angular orientation and the centerline of the cycloid should be aligned with the center of the output hole. The cycloid’s shortest length should be equal to the radius of the pin circle. The cycloid’s largest radius should be the size of the bearing’s exterior diameter.
A single-stage gear will not have much space to work with, so you’ll need a multistage gear to maximize space. This is also the reason that cycloid gears are usually designed with a shortened cycloid.
To calculate the most efficient tooth profile for a cycloidal gear, a new method was devised. This method uses a mathematical model that uses the cycloid’s rotational direction and a few other geometric parameters. Using a piecewise function related to the distribution of pressure angle, the cycloid’s most efficient profile is determined. It is then superimposed on the theoretical profile. The new method is much more flexible than the conventional method, and can adapt to changing trends of the cycloidal profile.
Design
Several designs of cycloidal gearboxes have been developed. These gearboxes have a large reduction ratio in one stage. They are mainly used for heavy machines. They provide good torsional stiffness and shock load capacity. However, they also have vibrations at high RPM. Several studies have been conducted to find a solution to this problem.
A cycloidal gearbox is designed by calculating the reduction ratio of a mechanism. This ratio is obtained by the size of the input speed. This is then multiplied by the reduction ratio of the gear profile.
The most important factor in the design of a cycloidal gearbox is the load distribution along the width of the gear. Using this as a design criterion, the amplitude of vibration can be reduced. This will ensure that the gearbox is working properly. In order to generate proper mating conditions, the trochoidal profile on the cycloidal disc periphery must be defined accurately.
One of the most common forms of cycloidal gears is circular arc toothing. This is the most common type of toothing used today.
Another form of gear is the hypocycloid. This form requires the rolling circle diameter to be equal to half the base circle diameter. Another special case is the point tooth form. This form is also called clock toothing.
In order to make this gear profile work, the initial point of contact must remain fixed to the edge of the rolling disk. This will generate the hypocycloid curve. The curve is traced from this initial point.
To investigate this gear profile, the authors used a 3D finite element analysis. They used the mathematical model of gear manufacturing that included kinematics parameters, output moment calculations, and machining steps. The resulting design eliminated backlash.
Sizing and selection
Choosing a gearbox can be a complex task. There are many factors that need to be taken into account. You need to determine the type of application, the required speed, the load, and the ratio of the gearbox. By gaining this information, you can find a solution that works best for you.
The first thing you need to do is find the proper size. There are several sizing programs available to help you determine the best gearbox for your application. You can start by drawing a cycloidal gear to help you create the part.
During sizing, it is important to consider the environment. Shock loads, environmental conditions, and ambient temperatures can increase wear on the gear teeth. The temperature also has a significant impact on lubrication viscosities and seal materials.
You also need to consider the input and output speed. This is because the input speed will change your gearbox ratio calculations. If you exceed the input speed, you can damage the seals and cause premature wear on the shaft bearings.
Another important aspect of sizing is the service factor. This factor determines the amount of torque the gearbox can handle. The service factor can be as low as 1.4, which is sufficient for most industrial applications. However, high shock loads and impact loads will require higher service factors. Failure to account for these factors can lead to broken shafts and damaged bearings.
The output style is also important. You need to determine if you want a keyless or keyed hollow bore, as well as if you need an output flange. If you choose a keyless hollow bore, you will need to select a seal material that can withstand the higher temperatures.

Cyclone Gearbox Vs Involute Gearbox
Whether you’re using a cycloidal gearbox or an involute gearbox for your application, there are a few things you should know. This article will highlight some of those things, including: cycloidal gearbox vs involute gearbox, weight, compressive force, precision, and torque density.
Compressive force
Several studies have been carried out to analyze the static characteristics of gears. In this article, the authors investigate the structural and kinematic principles of a cycloidal gearbox. The cycloidal gearbox is a gearbox that uses an eccentric bearing inside a rotating frame. It has no common pinion-gear pair, and is therefore ideal for a high reduction ratio.
The purpose of this paper is to investigate the stress distribution on a cycloidal disc. Various gear profiles are investigated in order to study the load distribution and dynamic effects.
Cycloidal gearboxes are subject to compression and backlash, which require the use of proper ratios for the bearing rate and the TSA. The paper also focuses on the kinematic principles of the reducer. In addition, the authors use standard analysis techniques for the shaft/gear and the cycloidal disc.
The authors previously worked on a rigid body dynamic simulation of a cycloidal reducer. The analysis used a trochoidal profile on the cycloidal disc periphery. The trochoidal profile is obtained from a manufacturing drawing and takes into account the tolerances.
The mesh density in the cycloidal disc captures the exact geometry of the parts. It provides accurate contact stresses.
The cycloidal disc consists of nine lobes, which move by one lobe per rotation of the drive shaft. However, when the disc is rotated around the pins, the cycloidal disc does not move around the center of gravity. Therefore, the cycloidal disc shares torque load with five outer rollers.
A low reduction ratio in a cycloidal gearbox results in a higher induced stress in the cycloidal disc. This is due to the bigger hole designed to reduce the material inside the disc.
Torque density
Several types of magnetic gearboxes have been studied. Some magnetic gearboxes have a higher torque density than others, but they are still not able to compete with the mechanical gearboxes.
A new high torque density cycloidal magnetic gearbox using Halbach rotors has been developed and is being tested. The design was validated by building a CPCyMG prototype. The results showed that the simulated slip torque was comparable to the experimental slip torque. The peak torque measured was a p3 = 14 spatial harmonic, and it corresponds to the active region torque density of 261.4 N*m/L.
This cycloidal gearbox also has a high gear ratio. It has been tested to achieve a peak torque of 147.8 Nm, which is more than double the torque density of the traditional cycloidal gearbox. The design incorporates a ferromagnetic back-support that provides mechanical fabrication support.
This cycloidal gearbox also shows how a small diameter can achieve a high torque density. It is designed with an axial length of 50mm. The radial deflection forces are not serious at this length. The design uses a small air gap to reduce the radial deflection forces, but it is not the only design option.
The trade-off design also has a high volumetric torque density. It has a smaller air gap and a higher mass torque density. It is feasible to make and mechanically strong. The design is also one of the most efficient in its class.
The helical gearing design is a newer technology that brings a higher level of precision to a cycloidal gearbox. It allows a servomotor to handle a heavy load at high cycle rates. It is also useful in applications that require smaller design envelopes.
Weight
Compared to planetary gearboxes, the weight of cycloidal gearboxes is not as significant. However, they do provide some advantages. One of the most significant features is their backlash-free operation, which helps them deliver smooth and precise movement.
In addition, they provide high efficiency, which means that servo motors can run at higher speeds. The best part is that they do not need to be stacked up in order to achieve a high ratio.
Another advantage of cycloidal gearboxes is that they are usually less expensive than planetary gearboxes. This means that they are suitable for the manufacturing industry and robotics. They are also suited for heavy-duty robots that require a robust gearbox.
They also provide a better reduction ratio. Cycloidal gears can achieve reduction ratios from 30:1 to 300:1, which is a huge improvement over planetary gears. However, there are few models available that provide a ratio below 30:1.
Cycloidal gears also offer more resistance to wear, which means that they can last longer than planetary gears. They are also more compact, which helps them achieve high ratios in a smaller space. The design of cycloidal gears also makes them less prone to backlash, which is one of the major shortcomings of planetary gearboxes.
In addition, cycloidal gears can also provide better positioning accuracy. In fact, this is one of the primary reasons for choosing cycloidal gears over planetary gears. This is because the cycloid disc rotates around a bearing independently of the input shaft.
Compared to planetary gearboxes, cycloidal gears are also much shorter. This means that they provide the best positioning accuracy. They are also 50% lighter, meaning that they have a smaller diameter.
Precision
Several experts have studied the cycloidal gearbox in precision reducers. Their research mainly focuses on the mathematical model and the method for precision evaluation of cycloidal gears.
The traditional modification design of cycloidal gears is mainly realized by setting various machining parameters and center position of the grinding wheel. But it has some disadvantages because of unstable meshing accuracy and uncontrollable tooth profile curve shape.
In this study, a new method of modification design of cycloidal gears is proposed. This method is based on the calculation of meshing backlash and pressure angle distribution. It can effectively pre-control the transmission accuracy of cycloid-pin gear. It can also ensure good meshing characteristics.
The proposed method can be applied in the manufacture of rotary vector reducers. It is also applicable in the precision reducer for robots.
The mathematical model for cycloidal gears can be established with the pressure angle a as a dependent variable. It is possible to calculate the pressure angle distribution and the profile pressure angle. It can also be expressed as DL=f(a). It can be applied in the design of precision reducers.
The study also considers the root clearance, the backlash of gear teeth and the profile angle. These factors have a direct effect on the transmission performance of cycloidal gear. It also indicates the higher motion accuracy and the smaller backlash. The modified profile can also reflect the smaller transmission error.
In addition, the proposed method is also based on the calculation of lost motion. It determines the angle of first tooth contacts. This angle is an important factor affecting the modification quality. The transmission error after the second cycloid method is the least.
Finally, a case study on the CZPT RV-35N gear pair is shown to prove the proposed method.
Involute gears vs cycloidal gears
Compared to involute gears, cycloidal gears have a lower noise, less friction, and last longer. However, they are more expensive. Cycloidal gears can be more difficult to manufacture. They may be less suitable for certain applications, including space manipulators and robotic joints.
The most common gear profile is the involute curve of a circle. This curve is formed by the endpoint of an imaginary taut string unwinding from the circle.
Another curve is the epicycloid curve. This curve is formed by the point rigidly attached to the circle rolling over another circle. This curve is difficult to produce and is much more expensive to produce than the involute curve.
The cycloid curve of a circle is also an example of the multi-cursor. This curve is generated by the locus of the point on the circle’s circumference.
The cycloid curve has the same diameter as the involute curve, but is tangentially curving along the circle’s diameter. This curve is also classified as ordinary. It has several other functions. The FE method was used to analyze the strain state of cycloidal speed reducers.
There are many other curves, but the involute curve is the most widely used gear profile. The involute curve of a circle is a spiraling curve traced by the endpoint of an imaginary tautstring.
Involute gears are a lot like a set of Lego blocks. They are a lot of fun to play with. They also have a lot of advantages. For example, they can handle center sifts better than cycloidal gears. They are also much easier to manufacture, so the cost of involute teeth is lower. However, they are obsolete.
Cycloidal gears are also more difficult to manufacture than involute gears. They have a convex surface, which leads to more wear. They also have a simpler shape than involute gears. They also have less teeth. They are used in rotary motions, such as in the rotors of screw compressors.
