The impact crusher is one of the commonly used mine crusher equipment. When repairing the crusher equipment, sometimes it is necessary to disassemble the motor. Then, what are the precautions for the disassembly and assembly of the impact crusher motor?

1). For the motor equipped with rolling bearings, the outer cover of the bearing should be removed, the fastening screw of the end cover is loosened, and the mark of the end cover and the seams shall be marked (the mark of the front and back two ends should not be the same), and the screws of the unloaded fastening end cover are screwed into the two screw holes specially set on the motor end cover, and the end cap is put on the top. Out.

2) when removing the motor with brushes, remove the brush from the brush holder, mark the position of the neutral line of the brush.

3). When pumping out the rotor, we must pay attention to not bruising the stator coil, the weight of the rotor is not large, can be pulled out with the hand; the weight of the larger should be lifted with the lifting equipment. First, both ends of the rotor shaft are used for reusing the wire rope to lift the rotor with lifting equipment, and slowly move out.

4). Use tools to disassemble the wheel or coupling on the shaft of the motor. Sometimes you need to add some kerosene in the gap between the motor shafts of the wheel so that it can be penetrated and lubricated so that it is easy to disassemble. Some of the shaft and wheel are tightly matched, and the wheels need to be heated rapidly (with the wet cloth wrapped around the shaft) to remove the wheels.
