Disc coupling disc is parts of a diaphragm coupling, or a diaphragm coupling fitting.
Characteristics of Disc Coupling Disc:
The shaft diaphragm consists of several groups of diaphragms (stainless steel sheet). Interlock the two halves with bolts. Each group of diaphragms is composed of several sheets stacked on top of each other. Diaphragm is divided into connecting rod type and different shape of the whole plate. The relative displacement of the connected two shafts is compensated by the elastic deformation of the diaphragm coupling. It is a kind of high performance flexible coupling with metal strong element. No oil, compact structure, high strength, long service life. No rotation gap, not affected by temperature and oil. It is resistant to acid, alkali and corrosion. It is suitable for shafting drive under high temperature, high speed and corrosive medium working conditions.
Coupling Plate Pack Feature:
The coupling diaphragm consists of at least one diaphragm and two bushings. The diaphragm is fastened to the sleeve with a pin and will not generally loosen or cause recoil between the diaphragm and the sleeve. Some manufacturers supply two diaphragm. There are also three diaphragms with one or two rigid elements in the middle. Connect the two sides to the bushing. The difference between a single diaphragm coupling and a double diaphragm coupling is the ability to deal with various deviations. In view of its need for the diaphragm can be complex bending. So the single diaphragm coupling is not suitable for eccentricity. The double diaphragm coupling can bend in different directions at the same time. To compensate for the eccentricity.
