During the use of our mixers, a phenomenon of shaft breakage may occur. What are the causes of this issue? Our staff will briefly introduce the related knowledge points in the following.

1. Incorrect selection can lead to insufficient power output of the mixing equipment. Some users mistakenly believe that as long as the rated output torque of the selected mixer meets the working requirements, it is sufficient. However, this is not the case. If there is an issue with the equipment installation, and the output shaft and its load are jammed, the motor's overload capacity will still cause it to continually increase power output. Consequently, the force on the output shaft may exceed twice its rated output torque, potentially snapping the output shaft of the reducer. 2. During acceleration and deceleration, if the instantaneous torque on the mixer's output shaft exceeds twice its rated output torque, and these accelerations and decelerations occur too frequently, it can also cause the reducer's shaft to break. Considering the overload capacity of the driving motor and the actual need for a larger working torque, theoretically, the required larger working torque by the user must be less than twice the rated output torque of the reducer.
