The diaphragm coupling is composed of several sets of diaphragms (stainless steel thin plates) connected to the two halves of the coupling in a staggered manner with bolts. Each set of diaphragms is composed of several stacked pieces, and the diaphragms are divided into connecting rod type and integral pieces of different shapes.

●Diaphragm couplingCompensating for the relative displacement of the two shafts connected by the elastic deformation of the diaphragm is a high-performance metal elastic element flexible coupling. It does not require lubrication, has a compact structure, high strength, long service life, no rotational clearance, and is not affected by temperature and oil pollution. It has the characteristics of acid resistance, alkali resistance, and corrosion resistance, and is suitable for shaft transmission in high-temperature, high-speed, and corrosive medium working environments. It is widely used in shaft transmission of various mechanical devices, such as water pumps (especially high-power and 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. The sentence is:.

Compared with toothed couplings, diaphragm couplings have no relative sliding, no need for lubrication or sealing, no noise, basically no need for maintenance, and are easier to manufacture. They can partially replace toothed couplings. JZM type diaphragm coupling is a high-performance flexible coupling that is widely promoted and applied in China, and 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.
