Gear reducer shaft breakage

Except for the broken shaft of the gear reducer due to the poor concentricity of the output of the gear reducer, the output shaft of the gear reducer is broken, which is due to the following reasons.

First of all, the wrong selection results in insufficient output of the gear unit. Some users mistakenly believe that as long as the rated output torque of the selected gear reducer meets the working requirements, it is not the case. First, the rated output torque of the motor is multiplied by the reduction ratio, and the obtained value is in principle smaller than The rated output torque of the similar reducer provided by the product sample, and the overload capability of the drive motor and the maximum working torque required in practice are also considered. In theory, the maximum working torque required by the user. Must be less than 2 times the rated output torque of the gear reducer.

In particular, in some applications, this criterion must be strictly observed. This is not only the protection of the gear reducer, but also the interruption of the output shaft of the gear reducer. This is mainly because if the equipment is installed with problems, the output shaft of the gear reducer and its load are stuck. At this time, the overload capability of the drive motor will continue to increase the output, and thus the output of the gear reducer may be made. The bearing is subjected to a force exceeding 2 times its rated output torque and the output shaft of the gear reducer is broken.

Secondly, in the process of acceleration and deceleration, if the output torque of the gear reducer is multiplied by twice the rated output torque and the acceleration and deceleration are too frequent, the gear reducer will eventually Broken shaft.
