What are the key points for selecting planetary reducer?

The planetary gear reducer is the most important type of reducer for matching servo motors. When choosing a planetary gear reducer, the first thing to do is to determine the gear ratio. If the standard reducer does not have the gear ratio you need, please choose a close one or customize the reducer from our company.

The selection of planetary gear reducers is one of the most important types of reducers that match servo motors. When selecting planetary gear reducers, there are several key points to consider.
 
Firstly, it is very important to determine the reduction ratio. If the standard reducer does not have the reduction ratio you need, you can choose a close reduction ratio or customize the reducer from the manufacturer. After determining the reduction ratio, you need to multiply the rated torque of the selected servo motor by the reduction ratio. The resulting value should be smaller than the rated output torque provided by the similar reducers in the product catalog. At the same time, the overload capacity of the driving motor and the maximum working torque required in practice should also be considered. The maximum working torque required should be within twice the rated output torque. After meeting these conditions, you can choose the smallest reducer, because the smaller the volume of the reducer, the lower the cost.
 
Another key point is to consider the backlash of the planetary gear reducer. The smaller the backlash, the higher the accuracy, but the higher the cost. Users need to choose the appropriate reducer according to their own precision requirements. In addition, it is also necessary to consider the lateral and radial forces and the average life. Reducers with large lateral and radial forces are more reliable in installation and use and are less likely to have problems. Generally, the average life of these reducers far exceeds the life of the matched servo motor.
 
When selecting, it is also necessary to consider the working environment and conditions of the reducer. For example, if the reducer needs to be used in a humid or high-temperature environment, a reducer with waterproof and dustproof or high-temperature resistance characteristics should be selected.
 
In summary, the selection of planetary gear reducers needs to comprehensively consider factors such as reduction ratio, torque, accuracy, force, life, and working environment to ensure that the selected reducer can meet actual work requirements and has good reliability and durability.
