Several sets of diaphragms (stainless steel sheets) are connected to the two halves of the coupling with bolts in a staggered manner. Each set of diaphragms is composed of several stacked pieces, and the diaphragms are divided into connecting rod type and whole piece type with different shapes. The diaphragm coupling compensates for the relative displacement of the two shafts connected by the elastic deformation of the diaphragm. It is a high-performance metal strong component flexible coupling that does not require lubrication, has a compact structure, high strength, long service life, no rotational clearance, is not affected by temperature and oil pollution, and has the characteristics of acid resistance, alkali resistance, and corrosion resistance. It is suitable for shaft transmission in high-temperature, high-speed, and corrosive medium working conditions
