Factors to be considered in the selection of cycloidal reducer

There are many factors to consider when choosing a suitable cycloid reducer. Today we pick out several important factors to share with you.

In addition to the technical requirements for selecting the reducer, what other requirements are there? Some of the more common methods are discussed below.

ambient temperature

An important but sometimes overlooked factor is temperature. For example, the motor rating is based on a certain ambient temperature, usually 40 ℃. If the application is continuous operation with high ambient temperature, motors with rated torque higher than the calculated value may be required.

Duty cycle

For motor and cycloid reducer, the duty cycle will affect the temperature rise of motor and gear wear rate. If the application has intermittent duty cycles, motors with rated torque lower than the calculated value can be used. However, frequent start and stop will reduce the expected life of the gear. This is also related to the service factors published by the gear manufacturer in its catalogue.

Overall dimension

The shape factor is another parameter that affects the operation. For example, when a DC motor speed controller is used, the shape factor of the DC voltage output by the controller will affect the motor size and transmission ratio, and whether a cycloid reducer is required. One factor in increasing motor temperature is unfiltered control. This means that a larger motor than calculated may be required, especially when the duty cycle is continuous. The speed of the motor will also slow down because such a control has a lower output voltage than the filter control. This is why it is so important to use the correct motor speed when calculating the transmission ratio.

Radial and axial loads

The load also affects the motor bearings. In particular, motors have different types and sizes of bearings, and each bearing has different radial and axial load capacity. Similarly, depending on the load capacity, a larger motor than calculated may be required. For example, applications with high radial loads, such as pinch rolls and belt drives, may require larger motors. However, applications with high axial loads, such as lead screws, may require larger motors. In this sense, bigger means a more powerful motor, not necessarily more output power.
