Detailed parameters of JMⅠ basic diaphragm coupling with counterbore
JMI type basic diaphragm coupling with counterbore is suitable for shafting transmission in high temperature, high speed, and corrosive medium conditions. It is widely used for shafting transmission of various mechanical devices, 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 (helicopter), naval high-speed power transmission system, after being dynamically balanced, applied to high-speed transmission Shafting has become more common.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. Diaphragm couplings are industrially developed countries in the world. The application has been very common. In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.

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, high strength and long service life. Long, no rotation gap, not affected by temperature and oil pollution, and has the characteristics of acid resistance, alkali resistance and corrosion resistance.
