How to select reducer
To determine the model of a reducer, the following parameters need to be determined:
1. Determine the running speed of the machine, and calculate the reduction ratio of the reducer according to this speed (reduction ratio=input shaft speed/output shaft speed=motor speed/mechanical required speed);
2. Calculate the load torque, select the output of the reducer according to this torque (refer to the “Output Torque Table” provided by the reducer manufacturer), and determine the reducer model;
3. Determine the additional functions of the reducer, such as power off braking, power on braking, frequency conversion, shrink frame, housing material, etc. Some additional functions can only be provided by specific factories.

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.
History of Cycloidal Gear System Development
The history of cycloidal gear systems dates back to ancient times, with various forms of non-circular gears being used for specialized applications. The concept of the cycloidal gear system as we know it today, however, has evolved over centuries of engineering and innovation:

Principle of Cycloidal Gearing
Cycloidal gearing is a mechanism that utilizes the unique shape of cycloidal discs to achieve motion transmission. The principle involves the interaction between two main componen
Use of Cycloidal Gearboxes in Precision Applications
Cycloidal gearboxes are well-suited for precision applications due to their unique design and capabilities. Here’s why they are used in precision settings:
- High Positional Accuracy: Cycloidal gearboxes offer high positional accuracy, making them suitable for applications that require precise positioning and movement.
- Backlash Reduction: The design of cycloidal gearboxes minimizes backlash, ensuring that there is minimal play between gears. This is crucial for maintaining accuracy in precision applications.
- Smooth and Controlled Motion: Cycloidal gearboxes provide smooth and controlled motion with minimal vibration, which is essential for delicate operations and precision machinery.
- Compact Design: Their compact design allows cycloidal gearboxes to be integrated into tight spaces without sacrificing performance. This is especially valuable in applications where space is limited.
- Repeatable Performance: Cycloidal gearboxes offer consistent and repeatable performance, which is vital for maintaining precision over multiple cycles.
- Low Backlash: The low backlash characteristic of cycloidal gearboxes ensures that there is minimal lost motion, contributing to their precision performance.
- High Torque Density: Despite their compact size, cycloidal gearboxes can handle high torque loads, making them suitable for applications that require both precision and power.
- Reduced Wear: The rolling contact design of cycloidal gears reduces wear and extends the lifespan of the gearbox, which is crucial for precision applications that demand consistent performance over time.
Overall, cycloidal gearboxes are a reliable choice for precision applications that require accurate positioning, controlled motion, and consistent performance.
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.
- Backlash: They typically exhibit low backlash due to the nature of the engagement mechanism, making them advantageous for applications requiring precise and reversible motion.
- 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.
