Note: 1. The allowable output speed is affected by duty cycle, load, and ambient temperature. When the allowable output speed is above NS1, please consult our company about the precautions.
2. Calculate the input capacity (kW) by the following formula.
Input capacity (kW)=2π*N*T/60*η/100*10*10*10 N: output speed (RPM)
T: output torque (nm)
η =  75: reducer efficiency (%)
The input capacity is the reference value.
3. When using the reducer at a low temperature, the no-load running torque will increase, so please pay attention when selecting the motor.

Variations in Cycloidal Gearbox Design

Cycloidal gearboxes come in various designs and configurations to cater to different application requirements. Some common variations include:

  • Single-Stage vs. Multi-Stage: Cycloidal gearboxes can be designed as single-stage or multi-stage systems. Single-stage designs offer a lower gear ratio and are suitable for applications with moderate torque requirements. Multi-stage designs provide higher gear ratios and are used for applications demanding higher torque output.
  • Input and Output Arrangements: Cycloidal gearboxes can have various input and output arrangements, including coaxial, inline, and right-angle configurations. These arrangements determine the orientation of the input and output shafts relative to each other.
  • Size and Torque Capacity: Different sizes of cycloidal gearboxes are available to accommodate a wide range of torque and power requirements. Smaller sizes are suitable for applications where space is limited, while larger sizes handle higher torque loads.
  • Mounting Options: Cycloidal gearboxes offer flexibility in mounting options, including base or flange mounting. This allows for easy integration into different types of machinery and equipment.
  • Material Selection: Depending on the application’s demands, cycloidal gearboxes can be constructed using various materials, such as steel, aluminum, and alloys. Material selection affects the gearbox’s durability and performance in different environments.
  • Backlash Reduction Mechanisms: Some cycloidal gearboxes feature enhanced backlash reduction mechanisms to further improve precision and accuracy in motion control applications.

These variations in design allow cycloidal gearboxes to be tailored to specific application requirements, making them versatile solutions for a wide range of industries and machinery.

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 components: 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 continuous 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.
