The dual diaphragm coupling relies on the elastic deformation of the diaphragm to compensate the relative displacement of the two coupled shafts. It is a high-performance flexible coupling of metal elastic elements. It does not require lubrication, has a compact structure, high strength, and a long service life. ， No rotation gap, not affected by temperature and oil pollution. It has the characteristics of acid resistance, alkali resistance and anti-corrosion. It is suitable for high-speed, high-speed, and corrosive media working conditions. It is widely used in various mechanical devices. Transmissions, 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 for ships Transmission system, steam turbine piston power mechanical transmission system
Selection example Example: HY-34-1012 HY: Double diaphragm type 34: outer diameter size 10:d1 shaft diameter 12:d2 shaft diameter Note: The keyway needs to be additionally marked
