I think everyone has some understanding of the elastic diaphragm coupling, but many people do not know much about its structure. In fact, its composition is relatively simple. Shaft, intermediate sleeve, compression element, bolt, lock nut, limit washer, etc. The torque is input from the half-coupling at the active end, and the torque is transmitted to the front-end flexible steel sheet group through the higher-strength bolts arranged at intervals along the circumference, and then the flexible steel sheet group is transmitted to the intermediate sleeve through the higher-strength bolts , and is also output by the other back-end flexible steel sheet group, bolts and driven half-coupling.


How to disassemble the elastic diaphragm coupling
1. Assembly
First use a fine iron emery cloth to smooth the shaft hole of the shaft, pulley or coupling, align the pulley or coupling with the keyway and put it on the shaft, use wrought iron or hardwood to pad one end of the key, tap the key lightly into the slot.
The key should be moderately tight in the groove. Too tight or too loose will damage the key and the groove, and if it is too loose, the belt will slip or vibrate. Drum gear coupling is a new type of gear coupling developed by digesting and absorbing foreign technology on the basis of spur gear coupling.
2. Disassembly
First mark the position between the pulley or the coupling and the rotating shaft, tighten the factory fixing screws and pins, and then slowly pull it out with a puller. If you can't pull it, you can pour some kerosene in the inner hole and pull it again. If it still can't be pulled out, use an emergency fire to quickly heat the pulley or coupling, wrap the shaft with a damp cloth, and pour cold water continuously to prevent heat from entering the motor.

The transmission problem of elastic diaphragm coupling, in fact, in general, one or several diaphragm couplings connect the main and driven shafts, and then form a shaft transmission system to transmit rot
