How to remove the motor end cover

1. In order to avoid mistakes during assembly, mark the joint between the casing and the end cover before removing the end cover.

2. Before disassembling the sliding bearing end cover, the grease (oil) should be released first, and the oil ring should be lifted and tied.

3. For the slip ring or commutator motor, take out or lift up and fasten the brush, and mark the position of the brush holder. Be careful not to damage the brush and the lifting device when removing it.

4. For motors equipped with roller bearings at the load end, the non-load end should be disassembled first.

5. Generally, small motors only need to remove the end cover on the fan side, first remove the screws on the end cover, and then pull out the rotor, end cover, bearing cover and fan together.

6. For large and medium-sized motors, the end covers on both sides need to be removed due to the heavy rotor. When disassembling the double-sided end cover, first loosen the upper cover screws, then loosen the lower cover screws, then lift the upper cover, pry it open, remove the upper tile, take out the oil ring, take off the lower tile, and remove the lower cover. For ease of assembly, the load end and the non-load end should be marked when dismantling.

7. When removing the end cover of the rolling bearing, the small cover should be removed first, then the large cover should be vibrated and screwed, and the large cover should be removed.

8. In order to prevent the stator and rotor from being damaged by collision, insulating cardboard should be placed in the air gap after removing the end cover.

9. The dismantled small parts should be stored in a special parts box, and each group of parts should be matched together as they are to facilitate the general assembly.
