JMI type diaphragm coupling
The JMI basic diaphragm coupling with counterbore is elastically deformed 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, and has a long service life. , No rotation gap, not affected by temperature and oil pollution, acid and alkali resistance, suitable for shaft transmission in high temperature, high speed, and corrosive medium working conditions, and widely used in shaft transmission of various mechanical devices, such as Water pumps (especially high-power and 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, After being dynamically balanced, it is relatively common to apply to high-speed transmission shafts. Compared with gear couplings, there is no relative sliding, no lubrication, sealing, no noise, basically no maintenance, and more convenient manufacturing. It can partially replace gear couplings. Shaft. Diaphragm couplings have been widely used in advanced industries in Shanghai. In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.
