Why do planetary deceleration opportunities have broken axes? A possible problem with a large broken shaft is that there is a problem with the quality of the planetary reducer. Of course, this is what we usually think of, and the main reason is the reason for the usual use. For example, how do we pay attention to the process of accelerating and decelerating with a planetary reducer? Is there any good way? The following are three reasons for the summary of the small series.
1, Some applications must strictly abide by this criterion, which is not only the protection of the reducer, but also to avoid the output shaft of the planetary reducer being twisted. This is mainly because if the equipment is installed with a problem, the output shaft of the reducer and its load are stuck. At this time, the overload capability of the drive motor will continue to increase the output, and thus the output bearing of the reducer may be affected. The force exceeds twice the rated output torque and the output shaft of the reducer is broken.
2. In the process of acceleration and deceleration, if the torque of the output shaft of the planetary reducer is more than twice the rated output torque, and the acceleration and deceleration are too frequent, the reducer will also be broken. . Considering that this situation occurs less, it will not be further introduced here.
3, The wrong selection results in insufficient output of the gearbox. Some users mistakenly believe that as long as the rated output torque of the selected planetary reducer meets the working requirements, it is not the case. First, the rated output torque of the motor is multiplied by the reduction ratio, and the obtained value is in principle smaller than The rated output torque of the similar reducer provided by the product sample, and the overload capability of the drive motor and the large working torque required in practice are also considered. In theory, the user needs a large working torque. Must be less than 2 times the rated output torque of the reducer.
In the use of planetary reducers, we must pay attention to its code of conduct, and at the same time have a fatal output for the wrong selection. The broken shaft problem occurs when the output of the reducer is too small, and the broken shaft of the planetary reducer is a common problem. Except for the broken shaft of the reducer caused by the poor concentricity of the output of the reducer output. The above three points are the possible causes and problems.
