Helical-Bevel gearbox with broken shaft problem

In addition to the concentricity of the reducer output assembly is not good, resulting in the breakage of the reducer shaft, if the output shaft of the reducer is broken, there are no more than the following reasons. 

Firstly, the incorrect selection results in insufficient output of the gearbox. Some users mistakenly believe that as long as the rated output torque of the selected reducer meets the working requirements, otherwise, if the rated output torque of the distribution motor multiplies the deceleration ratio, the numerical value obtained is in principle smaller than the rated output torque of the similar reducer provided by the product sample, and the other is to consider at the same time. The overload capacity of the driving motor and the large working torque required in practice are discussed. In theory, users need large working torque. Edin is less than twice the rated output torque of the reducer.            

Especially in some applications, we must strictly abide by this rule, which is not only to protect the reducer, but also to avoid the output shaft of the reducer being twisted. This is mainly because if there is a problem in the installation of the equipment, the output shaft and its load of the reducer are stuck. At this time, the overload capacity of the driving motor will continue to increase its output force, and then, the output bearing of the reducer may be subjected to more than twice its rated output torque and the output shaft of the reducer will be broken.            

Secondly, in the process of acceleration and deceleration, if the instantaneous torque of the reducer output shaft is more than twice its rated output torque, and the acceleration and deceleration are too frequent, the reducer output shaft will eventually be broken. Considering that this situation occurs less frequently, it is no longer introduced here.
