JM¡¢JMJ elastic diaphragm coupling

JM¡¢JMJ series elastic diaphragm coupling£¨JB/T9147-1999£© ¡östructure features£º ¡ñAccording to the transmission torque and flexibility, it is divided into four, six, eight parts of linkage forms. ¡ñLarge load capacity, wide scope of application, long service life, the nominal torque is 25-1000000N.m ¡ñWorking temperature: -20¡«+250¡æ, no need of lubricate and can be worked in corrosion medium. ¡ñCompared with tooth coupling, it has simpler structure, easier processing and maintenance, smaller vibration, no noise. It is suitable used under high speed. ¡ñEasy assembly and checking. While disassembly, the transmission system drive and driven parts can not be demeshed of axial moving. ¡ñIt¡¯s widely used in metallurgy,steel rolling, mining, shipbuilding, pumping and fan  industry. ¡öMarked example£º ¡ñforms and marks: the hole and keyway are according to GB/T3852, length of shaft hole  optimizes L as the recommended value. 1¡¢JM4 diaphragm coupling:   Drive end£ºY hole of
