Brief introduction of diaphragm coupling

DiaphragmCouplingIt is composed of several groups of diaphragms (stainless steel thin plate) which are alternately connected with the two halves of the coupling with bolts. Each group of diaphragms is made up of several stacked ones. The diaphragms are divided into connecting rod type and whole piece type of different shapes. ● The 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, has a compact structure, high strength and long service life. , No rotation gap, not affected by temperature and oil pollution, with acid resistance, alkali resistance, and corrosion resistance. It is suitable for high temperature, high speed, and corrosive medium shafting. It is widely used in shafting of various mechanical devices. 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 (helicopter), high-speed naval power The transmission system, after being dynamically balanced, is commonly used in high-speed transmission shaft systems. ● Compared with the gear coupling, the diaphragm coupling has no relative sliding, no lubrication, sealing, no noise, basically no maintenance, more convenient to manufacture, and can partially replace the gear coupling.Diaphragm couplings have been widely used in developed countries in the world. In practical applications, the intermediate shaft type is generally used to improve the offset compensation performance of the two axes.
