Why the planetary gearing opportunities appear broken shaft imagination.

The first possible problem with the broken shaft is the quality of the coal mill gearbox. Of course, this is what we usually think of people, one of the most important reason is the usual use of the process of the reasons. For example, in the use of planetary reducer acceleration and deceleration in the process of how we should pay attention to what a good way. The following is a summary of the three reasons for the Shanghai.
First, some applications must strictly abide by this criterion, which is not only the protection of the reducer, more important is to avoid the planetary reducer output shaft was broken. This is mainly because, if the equipment is installed, the output shaft of the helical geared motors unit and its load are stuck, and then the overload capacity of the drive motor will continue to increase its output, which may cause the output shaft of the gear unit Of the force exceeds the rated output torque of the output shaft.
Second, in the process of acceleration and deceleration, the planetary reducer output shaft by instantaneous torque if more than its rated output torque of 2 times, and this acceleration and deceleration and too frequent, then the final will make the gear off axis. Taking into account the emergence of this situation less, so here is no further introduction.
Third, the wrong selection of the reducer caused by the output is not enough. Some users in the selection, mistakenly believe that as long as the selected planetary reducer rated output torque to meet the work requirements can be, it is not true, one is equipped with the rated output torque multiplied by the reduction ratio, the value is in principle to be less than The sample output of the similar speed reducer rated output torque, and second, but also to consider the drive motor overload capacity and the actual required maximum working torque. In theory, the user needs the maximum working torque. Must be less than 2 times the rated output torque of the reducer.
Which must use the planetary reducer must pay attention to its code of conduct, while the wrong selection of fatal reason is not enough reason. Reducer output is too small to break the axis of the problem, planetary reducer broken axis is a common problem. In addition to the reducer output end of the concentricity is not good, resulting in the reducer off the shaft.
