DJM single expansion joint magnetic disc flexible coupling

A diaphragm coupling consists of one or more metallic membranes which are attached at the outside diameter of a drive flange and transfers torque radially through the diaphragm to an inside diameter attachment. The other type of metallic membrane coupling is the disk coupling.

What is the advantages of diaphragm coupling 

Servo motors, which are indispensable for automatic control machinery, are widely used in connection with ball screws.

Expansion sleeve coupling, completely eliminate the transmission gap, more convenient disassembly and assembly

connecting shaft: the connecting shaft tolerance :shaft diameter> 38, take h8 shaft diameter <38, take H6

taper hole connecting, the shaft hole diameter refers to the  bigger size .

Product show : for the diaphragm ,we use good quality  high strength stainless steel  sheet .

coupling diaphragm

As the disc coupling have verious kinds of type ,so we also can make all of them ,such as single (double )disc coupling with single expansion sleeve ,with taper sleeve ,or the locking disc,even very small size or huge size ,or miniature disc coupling
