How to remove the motor housing when necessary?

The emergence of a motor products will be protected by the motor shell, then the need to remove the motor shell?

(1) for motor with rolling bearing, should first remove the bearing cover, then loosen the fastening screws of the end cover, and mark the end cover seams and base shell (two markers before and after the end cover should not be the same), two screw screws into the motor end will remove the fastening the cover of the cover specially set up, will be the top cover. There is no such screw motor, it can only be used chisel (also known as flat spade) and hammer end cover and the joint frame, the end cover is unloaded from the machine. If the end cover is heavier, the lifting device is used to lift the end cover and is gradually unloaded.

(2) out of the rotor, must pay attention not to damage the stator coil, not the weight of the rotor, you can hand out; the larger the weight lifting equipment should be used to hang out, first be set to both ends of rotor shaft hoisting wire rope hoisting equipment hang rotor, out slowly, pay attention to prevent damage coil. In the end of the shaft sleeve on a steel pipe, steel pipe in order not to scratch the shaft neck in steel pipe lined with a thick layer of cardboard will continue to gradually focus to be removed from the rotor, the rotor stator has been moved to the outside, the rotor shaft under a cushion bracket, the wire rope can be set in the middle of the rotor. All the spare rotor.

(3) to remove the external electrical wiring and mark, such as asynchronous motor, should mark corresponding to the three-phase power line, for the DC motor should be marked on each well and winding, an armature winding wiring etc and the corresponding. Then loosen the screws, the separation of electrical and mechanical transmission.

(4) use the tool to remove the pulley or coupling on the motor shaft, sometimes need to add some kerosene in the pulley with the motor shaft between the gap, so that the infiltration of lubrication, easy disassembly. Some shafts and wheels with tight, but also the need for rapid heating wheel can be removed.

(5) when removing the motor with brush, the brush should be removed from the brush holder, and the position of the neutral line of the brush should be marked on the DC motor.
