JMⅡJ Type Intermediate Shaft Type Diaphragm Coupling (JB/T 9147-1999)
The JMⅡJ intermediate shaft type diaphragm coupling is composed of several groups of diaphragms (stainless steel thin plate) which are alternately connected with two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragm is divided into Link type and different shapes of the whole piece type.The diaphragm coupling relies on the elastic deformation of the diaphragm to compensate for the relative displacement of the connected two shafts. It is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, has a compact structure, has a long service life, and does not rotate. The gap is not affected by temperature and oil pollution, and has the characteristics of acid and alkali resistance. It is suitable for shaft transmission in high temperature, high speed, and corrosive medium working conditions. It is widely used in shaft transmission of various mechanical devices, such as water pumps (especially It is a high-power, chemical pump), fan, compressor, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopter), high-speed power transmission system of naval vessels, dynamic balance Later, it has been widely used in high-speed transmission shaft systems.Compared with the gear coupling, the diaphragm coupling has no relative sliding, does not need lubrication, sealing, noise, basically does not require maintenance, and is more convenient to manufacture. It can partially replace the gear coupling. JZM diaphragm coupling is a high-performance flexible coupling popularized and applied in my country, and it has been widely adopted in developed industries.In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.
