Plum coupling, diaphragm coupling, elastic pin coupling, drum gear coupling_Hangzhou Hengli Transmission Machinery Co., Ltd.

Aluminum alloy elastic screw couplings usually have good performance and price advantages. In many practical applications of stepping and servo systems, elastic couplings are the recommended product.

The 304 stainless steel diaphragm usually has a plum shape, a polygonal ring shape, etc., and the bolts on the same distribution circle are respectively connected with the driving and driven flanges.

Compared with the gear coupling, the diaphragm of the coupling has no relative sliding, no lubrication, sealing, no noise, basically no maintenance, easy to manufacture, and can partially replace the gear coupling.

The elastic coupling is an integrally formed metal elastic body, usually cut from a metal round bar. The commonly used materials are aluminum alloy, stainless steel, and engineering plastics, which are suitable for various deviations and torque transmission.
