Double diaphragm coupling relies on the elastic deformation of the diaphragm to compensate the relative displacement of the two shafts. It is a high-performance flexible coupling for metal elastic components. It is not lubricated, has a compact structure, high strength and long service life. It has no rotating gap, 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 drive of high temperature, high speed and corrosive medium working conditions, and is widely used in shafting of various mechanical devices. Transmissions, such as 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 of ships Transmission systems, steam turbine piston-type power mechanical transmission systems, crawler-type vehicles, and high-speed, high-power mechanical transmission systems for generator sets have been widely used in high-speed transmission shafting after dynamic balancing. Compared with the toothed coupling, the diaphragm coupling has no relative sliding, no lubrication, no sealing, no noise, no maintenance, and is convenient to manufacture. It can partially replace the gear coupling.Feature:1. The strength of the elastic element is relatively high, and it is not only small in size but also compact in structure compared with other couplings that transmit the same torque.2, the performance is very stable, and the life is also very long.3. The manufacturing process is more complicated and the cost is higher.4, metal elastic components are common are diaphragm, bellows, connecting rods and so on.Metal elastic component couplings are mainly used in the following applications:1. Pumps and fans with high power and high speed.2. The impact torque is large and the load changes severely.3. Precision transmission machinery and data transmission system.4, high temperature, high precision transmission requirements.
