Worm gear reducer出现断轴时，我们应该用以下方法处理：
1. The dynamic balance of the brake wheel and the fluid coupling is poor.Usually the coupling is only subjected to static balance test, not dynamic balance test. There is a certain deviation in the dynamic balance of the coupling. When running at high speed, additional dynamic load will be generated on the shaft, which will increase the deformation and force of the shaft. , It will produce fatigue.
2. The deviation of the coaxiality between the worm gear reducer and the motor is too large.The reducer and the motor are connected through a coupling. The coaxiality requirements of the three are very strict. In actual production, the maintenance personnel often only pay attention to the lubrication and leakage of the reducer, plus the difficulty of detection and other reasons. Often ignored.The elastic body of the coupling has limited compensation capabilities. When the coaxiality between the reducer and the motor is large, additional alternating loads perpendicular to the axis will be generated on the shaft. After a long time operation, the fatigue speed will be accelerated.
3. Improper selection of coupling type and installation method.The drive device of the belt conveyor adopts an outer wheel drive torque-limiting hydraulic coupling. The outer wheel is fastened on the input shaft of the reducer during installation, and the elastic coupling is connected with the motor. It does not bear weight.
