Summary:The keyway flange diaphragm coupling relies on the elastic deformation of the diaphragm to compensate for the relative displacement of the connected two shafts. It is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, and has a compact structure and high strength. Long life, no rotation gap, not affected by temperature and oil pollution, and has the characteristics of acid resistance, alkali resistance and corrosion resistance.

　　The keyway flange diaphragm coupling relies on the elastic deformation of the diaphragm to compensate for the relative displacement of the connected two shafts. It is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, and has a compact structure and high strength. Long life, no rotation gap, not affected by temperature and oil pollution, acid resistance, alkali resistance, and corrosion resistance. It is suitable for shaft transmission in high temperature, high speed, and corrosive medium working conditions. It is widely used in various mechanical devices. Shaft transmission, 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), ships High-speed power transmission systems, after being dynamically balanced, are commonly used in high-speed transmission shaft systems.
