Its outstanding features:
1) Double-diaphragm and small axial opposite wheel type coupling is the patent product developed by our factory, the patent No ZL.99 2 46247.9.
2) With compact structure, the adjustment capacity, anti-impact and vibration-absorbing etc properties will be higher by 35%-40% than those of single diaphragm opposite wheel type.
3) Under unexpected diaphragm breakage conditions, the plum blossom shape flange can still transfer the torque, the safety property is good.
4) Mounting and dismounting are convenient, it does not need to remove the motor or speed-reducer.
Scope of application
It can be widely used in the electric generating plant, petrochemical plant, steelworks, mine machinery, cement machinery etc industrial equipment, especially it is suitable for the mine fan, rope lifter locations where the safety coefficient requirement is higher.
