By several groups of the diaphragm (stainless steel plate) with bolts staggered connection with two coupling halves, each diaphragm is made from several pieces of overlapping sets, the diaphragm is divided into different shapes-link and the whole piece. By elastic deformation of the diaphragm diaphragm couplings to compensate for the relative displacement of the two axes Union, is a high performance metal reinforcing elements flexible coupling, do not run the oil, the structure is more compact, high strength, long life shaft drive, no rotation gap, independent of temperature and oil slicks, with acid, alkali corrosion, suitable for high-temperature, high-speed, there are corrosive environmental conditions
