If the drive motor shaft is not broken, but the output shaft of the reducer is broken, in addition to the poor concentricity of the reducer output end assembly, there are also the following possible reasons:
First of all, the wrong type selection results in insufficient output of the equipped reducer. Some users mistakenly think that as long as the rated output torque of the selected reducer meets the working requirements, it is OK. First, the rated output torque of the matched drive motor multiplied by the speed ratio, and the value obtained is in principle less than the corresponding rated output torque provided by the reducer product sample; Secondly, the overload capacity of its drive motor and the maximum working torque required in practical application should also be considered. In theory, the maximum working torque required by the user must be less than 2 times the rated output torque of the reducer. Especially in some applications, this criterion must be strictly followed. This is not only to protect the internal gear and shaft system of the reducer, but also to prevent the output shaft of the reducer from being twisted.
If these factors are not taken into account, once the equipment is installed incorrectly, the output shaft of the reducer is jammed by the load, then the overload capacity of the drive motor will still make it continuously increase its output until the force borne by the output shaft of the reducer exceeds its maximum output torque, and the shaft will break. If there is a certain margin for the rated output torque of the reducer, the bad situation of twisting the output shaft will be avoided.
Secondly, in the process of acceleration and deceleration, if the instantaneous impact torque borne by the output shaft of the reducer exceeds 2 times of its rated output torque, and the acceleration and deceleration are too frequent, the reducer will eventually break the shaft. If this happens, the torque margin should be carefully calculated and considered.
