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.

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.

How Does a Cycloidal Gearbox Work?

A cycloidal gearbox operates on the principle of cycloidal motion to transmit rotational power. It consists of a set of components that work together to achieve smooth and efficient motion transmission:

  1. High-Speed Input Shaft: The gearbox is connected to a high-speed input shaft, typically driven by an electric motor or another power source.
  2. Cycloidal Pins or Rollers: Surrounding the input shaft are a series of cycloidal pins or rollers arranged in a circular pattern. These pins interact with the lobed profiles of the outer stationary ring.
  3. Outer Stationary Ring: The outer ring remains stationary and contains lobed profiles. The lobes are designed in a way that allows them to engage with the cycloidal pins as they rotate.
  4. Motion Transmission: As the input shaft rotates, it causes the cycloidal pins to move along the circular path. The interaction between the cycloidal pins and the lobed profiles of the outer ring results in a unique motion known as epicycloidal or hypocycloidal motion.

This motion generates torque that is transferred from the input shaft to the output shaft of the gearbox. The main advantage of a cycloidal gearbox is its ability to provide high torque output in a compact design. The multiple points of contact between the pins and the lobes distribute the load, enhancing the gearbox’s load-carrying capacity.

Cycloidal gearboxes are known for their smooth and controlled motion, making them suitable for applications requiring precise positioning and high torque capabilities, such as robotics, automation, and industrial machinery.
