JMⅡJ Type Intermediate Shaft Type Diaphragm Coupling
Summary:Compared with gear couplings, JMⅡJ type intermediate shaft diaphragm couplings have no relative sliding, no lubrication, sealing, no noise, basically no maintenance, more convenient manufacturing, and can partially replace gear couplings.
Compared with gear couplings, JMⅡJ type intermediate shaft diaphragm couplings have no relative sliding, no lubrication, sealing, no noise, basically no maintenance, more convenient manufacturing, and can partially replace gear couplings.
JMⅡJ intermediate shaft type diaphragm coupling is widely used in shaft transmission of various mechanical devices, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textiles High-speed power transmission systems of machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), and naval vessels are commonly used in high-speed transmission shaft systems after dynamic balance.
The JMⅡJ intermediate shaft diaphragm coupling is a high-performance flexible coupling that I focus on popularizing and applying, and it has been widely used in developed industries.In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.
The JMⅡJ intermediate shaft type diaphragm coupling is composed of several groups of diaphragms (stainless steel thin plate) which are alternately connected with the 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 JMⅡJ intermediate shaft diaphragm coupling compensates the relative displacement of the two shafts connected by the elastic deformation of the diaphragm. It is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, and has a compact structure and strength. High, long service life, no rotation gap, not affected by temperature and oil pollution, with acid resistance, alkali resistance, and corrosion resistance. It is suitable for high temperature, high speed, and corrosive medium operating conditions.
