Briefly analyze the key points of planetary gear reducer selection

来源: 发布日期:2019-6-11 9:37:56

  Planetary gear reducer is the most important type of reducer matching servo motor, when choosing planetary gear reducer.

  First, determine the reduction ratio of the reducer. If the standard reducer does not have the reduction ratio you need, please choose a close one or a customized reducer.

  After determining the reduction ratio, please multiply the rated torque of the servo motor you choose by the reduction ratio, and the value obtained is in principle less than the rated output torque of the similar reducer provided in the product catalog. At the same time, the overload of the drive motor must be considered. Capacity and maximum working torque required in practice.

  The maximum working torque required by the planetary gear reducer must be placed in 2 places of the rated output torque.After satisfying the above conditions, please choose the reducer with the smallest volume. The cost of the smaller reducer is relatively low.

  Next, consider the backlash of the planetary gear reducer.The smaller the return gap, the higher the accuracy and the higher the cost.Users can choose a series of reducers that meet their accuracy requirements.

  Planetary gear reducer also considers lateral/radial force and average life.The reducer with large lateral/radial force is highly reliable in installation and use, and it is not easy to cause problems.Usually its average life is much longer than the life of the equipped servo motor.
