The output shaft of reducer is also broken or bent.

The output shaft of the reducer is also broken or bent, the reason is the same as that of the drive motor. But the output of the reducer is the product of the drive motor output and the deceleration ratio. Compared with the motor, the output force of the reducer is larger, so the output shaft of the reducer is easier to be broken. Therefore, when users use the reducer, the assurance of the concentricity of the output assembly of the reducer should also be paid great attention. Secondly, in the process of acceleration and deceleration, if the instantaneous torque of the output shaft of the reducer exceeds twice its rated output torque, and the acceleration and deceleration are too frequent, the shaft of the reducer will eventually be broken. Considering that this situation occurs less frequently, we will not introduce it further here.

If the concentricity error of the reducer is large, the radial force will increase the temperature of the motor output shaft, and the metal structure will be destroyed continuously. Finally, the radial force will exceed the radial force that the motor output shaft can bear, which will eventually lead to the breakage of the drive motor output shaft. The greater the error of concentricity, the shorter the breaking time of the output shaft of the driving motor. When the output shaft of the drive motor is broken, the input end of the reducer will also bear the radial force from the motor. If the radial force exceeds the maximum radial load that the two can bear at the same time, the result will also lead to deformation or even fracture of the input end of the reducer. Therefore, it is very important to ensure concentricity in assembly.
