The definition of diaphragm coupling: a coupling that uses thin springs to connect with the two halves of the coupling by bolts or other coupling methods to realize the elastic connection of the two shafts. Several sets of diaphragms (stainless steel sheets) are staggered with bolts The ground is connected with the two halves of the coupling. Each group of diaphragms is made up of several pieces. The diaphragms are divided into connecting rod type and different shape integral type. The diaphragm coupling compensates for the connection by the elastic deformation of the diaphragm. The relative displacement of the two shafts is a high-performance metal flexible coupling without lubricating oil, compact structure, high strength, long service life, no rotation gap, not affected by temperature and oil, and acid resistance , Features of alkali resistance and corrosion resistance.
The diaphragm coupling is composed of at least one diaphragm and two shaft sleeves.The diaphragm is fastened to the shaft sleeve with a pin and generally does not loosen or cause the backlash between the diaphragm and the shaft sleeve.Some manufacturers provide two diaphragms, and others provide three diaphragms. There are one or two rigid elements in the middle, and the two sides are connected to the shaft sleeve. The difference between single diaphragm coupling and double diaphragm coupling The difference is the ability to deal with various deviations. In view of the need for complex bending of the diaphragm, 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 eccentricity.
