DJM type single expansion sleeve elastic diaphragm coupling
main feature:The eccentricity allows a wide range and can be flexibly applied to various transmission systems. Quick disassembly and assembly,easy repeatability No lubrication, no noise, no abrasion ,No sliding friction can reduce energy loss. Simple structure and light weight Maintenance-free, visual inspection during downtime Good environmental adaptability, can run at high temperature. High transmission accuracy. High reliability and long life.

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 .
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
