disc coupling

JMIIJ connected to the intermediate shaft diaphragm coupling

Time:18-09-20
Features and application of JMIIJ diaphragm coupling: Compared with flexible joints of metal elastic components, it has high mechanical strength, large bearing capacity, light weight, small size, high transmission efficiency and high transmission accuracy, and good reliability. Easy to remove and so on. Suitable for medium, high speed and large torque shaft drive. Compared with the drum-shaped gear coupling, it has no relative sliding, no lubrication, long service life, no noise, simple structure and so on. It can partially replace the drum-shaped toothed auxiliary device. Not affected by temperature and oil. It has the characteristics of acid resistance, alkali resistance and corrosion resistance. It can be used in high temperature, low temperature and working conditions with oil, water and corrosive media. It is suitable for shafting transmission with little change in load of various mechanical devices. It is extremely versatile and has been widely used in industrialized countries. It is a high-performance flexible coupling 重點(diǎn) which is mainly promoted and applied in China. High-precision diaphragm coupling can be used for High speed conditions. Compared with the toothed coupling, the diaphragm coupling has no relative sliding, no lubrication, no sealing, no noise, no maintenance, and is convenient to manufacture. It can partially replace the gear coupling. The diaphragm coupling has been widely used in industrialized countries in the world. In practical applications, the intermediate shaft type is generally adopted to improve the offset compensation performance of the two axes.
    JMI type - basic type with countersink;
    JMIJ type--with countersunk and intermediate shaft type;
    JMII type - no counterbore basic type;
    JMIIJ type - no countersinking intermediate shaft type;
