Why Does Planetary Gear Speed Reducers Opportunities Shaft Breakage?
Nov 30, 2018

Believe that in real life we often have questions: why does the planetary gear speed reducers break its axis? First, the most probable problem is the quality of planetary gear speed reducers. Of course, this is what we can think of in peacetime, the most important reason is the cause of peacetime use. For example, in the process of using planetary gear speed reducer to accelerate and decelerate, how should we pay attention to and what good methods are available? There are three reasons.

First, in some applications, this criterion must be strictly observed. This is not only the protection of the planetary gearbox, but also the main thing is to avoid the output shaft of the planetary gear reducer being twisted off. This is mainly because if there is a problem in the installation of the equipment, the output shaft and its load of the reducer are stuck. At this time, the overload capacity of the driving motor will continue to increase its output force, and then, the output bearing of the speed reducer may be subjected to more than twice its rated output torque and the output shaft of the reducer will be broken.

Second,In the process of acceleration and deceleration, the instantaneous torque on the output shaft of planetary gearbox will be broken if it exceeds twice the rated output torque, and the acceleration and deceleration are too frequent. Considering that this situation occurs less frequently, we will not introduce it further here.


Third,The incorrect selection results in insufficient output of the gearbox. Some users mistakenly believe that as long as the rated output torque of the planetary gear reducer meets the working requirements, it is not the case.

1. The rated output torque of the distribution motor multiplied by the deceleration ratio, and the value obtained is in principle smaller than the rated output torque of the similar reducer provided by the product sample.

2. The overload capacity of the driving motor and the maximum working torque required in practice should also be considered. In theory, the maximum working torque required by the user. Must be less than 2 times the rated output torque of the planetary reducer.
