Repair method of motor failure

In the process of long-term operation of the motor, various defects often appear: For example, the coupling between the reducer and the reducer transmits a large torque, and the coupling hole on the flange surface shows severe wear, which increases the cooperation space of the coupling, resulting in transmission The torque is not stable; after the motor shaft bearing is damaged, the bearing position formed is worn; the shaft head and the keyway are worn and so on. After such problems, the traditional methods mostly used repair welding or brush plating and machining batch to be the main one, but both of them have certain harms. You can not eliminate the thermal stress caused by the high temperature of repair welding, and it is easy to bend or crack. At the same time, the thickness of the coating binds the electric brush plating, and it simply falls, and the above two methods use metal to correct the metal. They cannot change the "hard-to-hard" The collaborative contact of each force will still constitute another wear.
