Why does the planetary deceleration opportunity break the shaft?

 

Why does the planetary deceleration opportunity appear to break the shaft? The biggest possible problem with the first broken shaft is the quality of the planetary reducer. Of course, this is what we can usually think of, and the main reason is the reason that arises in the ordinary course of use. For example, in the process of using the planetary speed reducer to accelerate and decelerate, we should pay attention to what is good. Here are three reasons why Shanghai Jin Chuan reducer is summarized.

   First, some applications must strictly abide by this criterion. This is not only the protection of the reducer, but also the main reason is to avoid the output shaft of the planetary reducer being torn off. This is mainly because, if there is a problem with the installation of the equipment, the output shaft of the reducer and its load are jammed. At this time, the overload capacity of the drive motor will continue to increase its output. As a result, the output bearing of the reducer may be affected. The force exceeds its rated output torque by 2 times and the output shaft of the reducer is broken.

   Second, in the process of acceleration and deceleration, if the momentary torque of the output shaft of the planetary speed reducer exceeds twice its rated output torque, and this acceleration and deceleration is too frequent, it will eventually make the speed reducer axis. Considering this situation is less, it will not be further described here.

   Third, the wrong type of selection led to a shortage of gearboxes. Some users mistakenly believe that as long as the rated output torque of the selected planetary reducer meets the working requirements, it is not true. First, the rated output torque of the allocated 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 is the same as the overload capacity of the drive motor and the maximum working torque required in practice. In theory, the user needs the maximum operating torque. Must be less than 2 times the rated output torque of the reducer.

   Among them, the use of a planetary gearbox must pay attention to its code of conduct, and at the same time, there is not enough fatal output for the wrong type selection。 The problem of broken shafts when the output of the speed reducer is too small, and the shaft breakage of the planetary speed reducer is a common problem。 Except for the broken shaft of the reducer caused by the poor concentricity of the output assembly of the reducer。 The above three points are the possible causes and problems。
