Why Does the Gear Reducer Break the Shaft

- Dec 31, 2020-

Why does the gear reducer show the problem of broken shaft, and the broken shaft of the gear reducer is a common question. Except for the shaft breakage of the reducer due to the lack of concentric at the output end of the reducer, if the output shaft of the reducer breaks, it is nothing more than the following reasons.

 

1. In the process of acceleration and deceleration, if the moment the torque applied to the output shaft of the gear reducer exceeds 2 times the additional output torque, and this acceleration and deceleration are too frequent, then the reducer will eventually be caused broken shaft. Considering that this kind of state is less present, so I won't introduce it further here.

 

2. The wrong type selection caused insufficient output of the equipped reducer. When selecting models, some users mistakenly believe that only the additional output torque of the selected gear reducer is sufficient to meet the job requirements. In fact, it is not. Firstly, the additional output torque of the equipped motor is multiplied by the reduction ratio, and the value obtained is in principle. It is less than the additional output torque of the nearby gear reducer provided by the product sample, and the other is that the overload capability of the drive motor and the maximum operating torque required in practice must also be considered. Theoretically, the maximum operating torque required by the user. It must be less than 2 times the additional output torque of the gear reducer.

 

3. In some applications, it is necessary to strictly abide by this principle. This is not only the maintenance of the gear reducer, but more importantly, it is to prevent the output shaft of the gear reducer from being twisted. This is mainly because, if the equipment is in doubt, the output shaft of the gear reducer and its load are jammed, at this time the overload of the drive motor will still make it continue to increase its output, which may cause the output of the gear reducer in trouble. The force received by the shaft exceeds 2 times the additional output torque and the output shaft of the reducer is twisted.
