- JMⅡ type no sink hole basic diaphragm coupling is made up of several groups of the diaphragm (stainless steel thin pull) staggered bolt coupling connection with two halves, each of the diaphragm by a set number of sheets stacked together, diaphragm points the link type and different shapes of the entire piece. It s elastic deformation to compensate for the relative displacement of the two axes Union, is a high performance metal elastic element flexible coupling, without lubrication, more compact structure, high strength , long life, non-rotating gap, independent of temperature and oil slicks, with acid, alkali, anti-corrosion characteristics, suitable for high temperature, high speed, there is shaft drive corrosive environmental conditions, and a wide variety of machinery shaft drive device, 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) , ship speed drivetrain, after balancing for high-speed shaft system is already quite common. Compared with gear coupling, no sliding, no lubrication, sealing, noise, basically no maintenance, manufacturing more convenient can partially replace gear coupling diaphragm couplings countries in the international industrial applications is very common, commonly used in practical applications received intermediate shaft type, in order to improve the performance of the two axes offset compensation.
