● Diaphragm coupling is composed of several groups of diaphragms (stainless steel thin pull) with bolts and two halves coupling coupling, each group of films from the stack of pieces, the diaphragm is divided into connecting rod and different Shape of the whole piece.

● diaphragm coupling elastic deformation of the diaphragm to compensate for the relative displacement of the two axes, is a high-performance metal elastic components flexible coupling, without lubrication, the structure is more compact, high strength, long service life , No rotation gap, not affected by temperature and oil, with acid, alkali, corrosion characteristics, suitable for high temperature, high speed, corrosive media conditions of the environment of the shaft drive, widely used in a variety of mechanical shaft 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 (helicopters) Transmission system, after the balance of motion used in high-speed transmission shaft has been more common.

● Diaphragm coupling compared with the gear coupling, no relative sliding, no lubrication, sealing, no noise, the basic no maintenance, manufacturing more convenient, can be part of the alternative gear coupling. JZM-type diaphragm coupling is the focus of the promotion and application of high-performance flexible coupling, and industrial developed countries have been widely used. In practice, the middle axle type is generally used to improve the offset compensation performance of the two axes.

• JMJ type diaphragm coupling
• JM Ⅱ type without counterbore
