Here are three reasons for Hengyu Guoqiang reducer.
1、 Some applications must strictly abide by this rule, which is not only to protect the reducer, but also to prevent the output shaft of planetary reducer from being twisted off. This is mainly because if there is a problem with the installation of the equipment and the output shaft and its load of the reducer are stuck, the overload capacity of the drive motor will continue to increase its output, and then the force on the output shaft of the reducer may exceed 2 times of its rated output torque and the output shaft of the reducer may be twisted off.
2、 In the process of acceleration and deceleration, if the instantaneous torque of the output shaft of planetary reducer is more than twice of its rated output torque, and the acceleration and deceleration are too frequent, the shaft of planetary reducer will be broken eventually. In view of the fact that this kind of situation appears less, it will not be further introduced here.
3、 The wrong type selection results in insufficient output of the reducer. Some users mistakenly believe that as long as the rated output torque of the selected planetary reducer meets the working requirements, in fact, it is not. First, the value obtained by multiplying the rated output torque of the motor with the reduction ratio is in principle less than the rated output torque of the similar reducer provided by the product sample, The other is to consider the overload capacity and the maximum working torque of the drive motor. Theoretically, the user needs the maximum working torque. It must be less than 2 times of the rated output torque of the reducer.
In the use of planetary reducer, we must pay attention to its code of conduct, at the same time, there are fatal reasons for the wrong selection of output is not enough. When the output of reducer is too small, the broken shaft of planetary reducer is a common problem. In addition to the reducer output end assembly concentricity is not good, resulting in the reducer shaft broken. The above three points are the possible causes and problems.
