JMJ type intermediate shaft type diaphragm coupling is a high-performance metal elastic coupling, which is connected by the middle sleeve and the diaphragm groups and half couplings on both sides through hinged hole bolts. The diaphragm group is made of multiple thin stainless steel plates. The diaphragm group can be divided into two types: connecting rod type and integral type according to different structures.

JMJ type intermediate shaft type diaphragm coupling relies on the elastic deformation of the diaphragms on both sides to compensate for the relative displacement of the two connected shafts. The main features are no need for lubrication, compact structure, high strength, long service life, no rotation gap, not affected by temperature and oil pollution, acid and alkali resistance, and corrosion resistance. It is suitable for shaft transmission in high temperature, high speed, and corrosive medium working environment.

Widely used in shaft transmission of various mechanical devices, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), and ship high-speed power transmission systems. After dynamic balancing, it is widely used in high-speed transmission shaft systems.
