Diaphragm Coupling
Diaphragm Coupling consists of several groups diaphragm (stainless steel sheet) staggered bolt connection with two coupling halves, each diaphragm is made from several pieces stacked set, the diaphragm is divided into different shapes-link and the entire piece. Diaphragm coupling by the elastic deformation of the diaphragm to compensate for the relative displacement of the two axes Union is a strong component of high-performance metal flexible coupling, do not run oil, more compact structure, high strength, long service life, no rotation gap, independent of temperature and oil slicks, with acid and alkali corrosion, suitable for high-temperature, high-speed, a corrosive medium conditions environment shaft drive.
