Why is the shaft of the micro reducer broken?
A.The micro reducer has overloaded for a long time,so the output shaft will break due to fatigue. You’d better operate in accordance with manufacturer's requirements to minimize the occurrence of such question.
B.The output shaft is not evenly loaded, the radial load is out of the rated range, or it is working at the rated force for a long time.
Now check if the load exceeds the rated range, and if so, replace the larger gearbox motor.
