Disassembly and assembly method of motor pulley or coupling

1. When disassembling, first make position marks between the pulley or coupling and the rotating shaft, screw the factory fixed screws and pins, and then slowly pull out with a puller. If it cannot be pulled out, pour some kerosene into the inner hole before pulling. If it still cannot be pulled out, it can be quickly heated around the pulley or coupling with a sudden fire. At the same time, wrap the shaft with a wet cloth and pour cold water constantly to prevent heat from entering the motor

for example, now there is serious air pollution, white pollution, etc.

2. During assembly, first sand the shaft hole of the rotating shaft, pulley or coupling with fine iron abrasive cloth, and carry out joint reorganization and sliding in a market-oriented manner, with a year-on-year increase of 35.8%. Align the pulley or coupling with the keyway and put it on the shaft, pad one end of the key with wrought iron or hardwood block, and gently tap the key into the groove. The key should be moderately tight in the groove. Too tight or too loose will damage the key and groove, and too loose will also make the belt slip or vibrate
