Why does the planetary reducer break the shaft?

Update:18-10-2022
Summary:...
The first possible problem with broken shafts is that there is a problem with the quality of the planetary reducer. Of course, this is what we can think of at ordinary times, and the main reason is the reason that occurs during the usual use. For example, what should we pay attention to when using the planetary reducer to accelerate and decelerate, and what are the good methods. The following is a summary of three reasons for Shanghai Nuoqiu reducer.
1. In some applications, this criterion must be strictly followed, which is not only to protect the reducer, but also to prevent the output shaft of the planetary reducer from being twisted off. This is mainly because if there is a problem with the installation of the equipment, the output shaft of the reducer and its load are stuck, and the overload capacity of the drive motor will still make it continue to increase its output, which may cause the output bearing of the reducer to be affected. The force exceeds twice its rated output torque and twists the output shaft of the planetary gearmotor.
2. In the process of acceleration and deceleration, if the instantaneous torque on the output shaft of the planetary reducer exceeds twice its rated output torque, and the acceleration and deceleration are too frequent, then the reducer will eventually Broken shaft. Considering that this situation is rare, it will not be further introduced here.
3. Wrong selection results in insufficient output of the reducer. When selecting models, some users mistakenly believe that as long as the rated output torque of the selected planetary reducer meets the working requirements, it is not the case. First, the rated output torque of the equipped motor is multiplied by the reduction ratio, and the value obtained is in principle less than The rated output torque of the similar reducer provided by the product sample, the second is to consider the overload capacity of the drive motor and the actual larger working torque required. In theory, the user needs a larger working torque. It must be less than 2 times the rated output torque of the reducer.

Among them, when using the planetary reducer, we must pay attention to its code of conduct, and at the same time, there is a fatal reason for insufficient output for wrong selection. The broken shaft problem of the reducer output is too small, and the broken shaft of the planetary reducer is a common problem. Except for the broken shaft of the reducer caused by the poor assembly concentricity of the output end of the reducer. The above three points are the possible reasons and problems.
