How to prevent the output shaft of the reducer from breaking?

We occasionally encounter the problem of output shaft breakage when using reducers due to human factors such as improper installation. Today, in order to help everyone use the equipment better, the editor will introduce in detail the methods to prevent the output shaft breakage of reducers:

Due to the issue of shaft breakage, experts specifically examined the cross-section of the output shaft of the drive motor and found that it was almost identical to the cross-section of the output shaft: the outer ring of the device's cross-section was brighter, while the color of the cross-section became darker towards the axis, and even broke at the axis. This fully explains that the main reason for the shaft breakage of the drive motor output shaft is that the motor and reducer did not reach a concentric position during assembly.
When the concentricity between the motor and the reducer is ensured very well during assembly, the output shaft of the motor only bears rotational force and runs smoothly. However, when they are not concentric, the output shaft has to bear radial force from the input end of the reducer. The long-term effect of this radial force will force the output shaft of the motor to bend, and the direction of bending will continue to change with the rotation of the output shaft. For example, the direction of lateral force changes 360 degrees every time the output shaft rotates.
If the concentricity error is large, the radial force will cause the temperature of the gearbox motor output shaft to rise and the metal structure to be continuously damaged. Then, the radial force will exceed the radial force that the motor output shaft can withstand, leading to the breakage of the drive motor output shaft; The larger the concentricity error, the shorter the time for the output shaft of the driving motor to break.
At the same time as the output shaft of the driving motor breaks, the input end of the reducer will also bear radial forces from the motor. If this radial force exceeds the radial load that both can bear, it will also cause deformation or even fracture of the input end of the reducer. Therefore, it is crucial for all of us to ensure concentricity during assembly.
