Three main reasons for the output of the gearbox to break

Introduction to the reducer manufacturer: Due to poor assembly concentricity at the output end of the reducer, the reducer shaft is broken.

The wrong selection resulted in insufficient output of the equipped reducer. Some users mistakenly believe that as long as the rated output torque of the selected reducer meets the working requirements, it is sufficient. In fact, this is not the case. Firstly, the rated output torque of the matched motor multiplied by the reduction ratio should obtain a value that is in principle smaller than the rated output torque of similar reducers provided in the product sample. Secondly, it is also necessary to consider the overload capacity of the driving motor and the maximum working torque required in practice.

In theory, the maximum working torque required by the user must be less than twice the rated output torque of the gearbox. Especially in some applications, this criterion must be strictly followed, not only to protect the gears inside the gearbox, but also to prevent the output shaft of the gearbox from being twisted and broken. This is mainly because if there is a problem with 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 still continuously increase its output, which may cause the output shaft of the reducer to bear more than twice its rated output torque and twist the output shaft of the reducer.

During the process of acceleration and deceleration, if the instantaneous torque applied to the output shaft of the gearbox exceeds twice its rated output torque, and this acceleration and deceleration are too frequent, it will ultimately cause the gearbox shaft to break.
