JMI type single diaphragm coupling with counterbore

JMI type single diaphragm with counterboreCouplingRelying 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, high strength, long service life, and no rotation gap. Affected by temperature and oil pollution, it has the characteristics of acid resistance, alkali resistance and corrosion resistance

JMI type single with counterboreDiaphragm couplingIt consists of several sets of diaphragms (stainless steel thin plate) with bolts staggered with two halvesCouplingConnected, each group of diaphragms is made up of several pieces stacked, and the diaphragms are divided into connecting rod type and whole piece type of different shapes.Coupling parts can be made of 45# steel and 304 stainless steel.

JMI type single with counterboreDiaphragm couplingRelying 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, high strength, long service life, and no rotation gap. Affected by temperature and oil pollution, it has the characteristics of acid resistance, alkali resistance, and corrosion resistance. It is suitable for shaft transmission in high temperature, high speed, and corrosive medium conditions. It is widely used in shaft transmission of various mechanical devices, such as water pumps (especially It is high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), high-speed power transmission systems for ships, dynamic balance Later, it has been widely used in high-speed transmission shaft systems.

Compared with gear couplings, JMI type counterbore single diaphragm couplings have no relative sliding, no lubrication, sealing, noise, basically no maintenance, more convenient manufacturing, and can partially replace gear couplings.DiaphragmCouplingThe application in developed countries in the world has been very common. In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.
