JMⅡJ Type Intermediate Shaft Type Diaphragm Coupling

The diaphragm coupling is composed of several groups of diaphragms (stainless steel thin plate) which are alternately connected with two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragms are divided into rod type and different shapes. The whole piece.

Product Details

　　The diaphragm coupling relies on the elastic deformation of the diaphragm to compensate for the relative displacement of the two shafts connected. It is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, has a compact structure, high strength and long service life. No rotation gap, not affected by temperature and oil pollution, with acid resistance, alkali resistance, and corrosion resistance. It is suitable for shafting transmission in high temperature, high speed, and corrosive medium working conditions. It is widely used for shafting 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 (helicopter), high-speed power transmission of ships The system, after being dynamically balanced, is commonly used in high-speed transmission shafts.

　　Compared with the gear coupling, the diaphragm coupling has no relative sliding, does not need lubrication, sealing, noise, basically does not require maintenance, and is more convenient to manufacture. It can partially replace the gear coupling. The JZM diaphragm coupling is a high-performance flexible coupling that is promoted and applied in my country, and it has been widely adopted in industrialized countries.In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.
