How to select planetary gear reducer and what are the key points of selection

Planetary gear reducer is also called planetary reducer and servo reducer. In the reducer family, planetary reducer is widely used in servo motor, stepping motor, DC motor and other drive systems because of its small size, high transmission efficiency, wide reduction range and high accuracy. Today, I will show you Li Aijie how to select planetary gear reducer and what are the key points of selection.

Planetary gear reducer is the most important type of reducer to match the servo motor. When selecting planetary gear reducer, first determine the reduction ratio of the reducer. If the standard reducer does not have the reduction ratio you need, please select a close or customized reducer.

Secondly, after determining the reduction ratio, please multiply the rated torque of the servo motor you choose by the reduction ratio, and the value obtained should be less than the rated output torque of the similar reducer provided in the product catalog in principle. At the same time, the overload capacity of the drive motor and the maximum working torque required in practice should also be tested. The maximum working torque required shall be noted in the 2nd place of the rated output torque. After the above conditions are met, please select the reducer with the smallest volume. The reducer with small volume has relatively low cost.

Also consider the return clearance of the planetary gear reducer. The smaller the return clearance, the higher the accuracy and the higher the cost. The user can select a series of reducers that meet the accuracy requirements. Lateral / radial forces and average life shall also be considered. The reducer with large lateral / radial force has high reliability in installation and use and is not easy to cause problems. Generally, the average life of the servo motor is much longer than that of the servo motor. Welcome to continue to browse the reducer manufacturer to learn more about the reducer.
