Diaphragm couplings are also called elastic laminated couplings, or laminated flexible couplings. One of the new types of couplings developed in recent years. The elastic element of the diaphragm coupling consists of a thin stainless steel membrane. Diaphragm components composed of laminated sheets, the diaphragm usually has a waist shape, a polygonal ring shape, etc., and the precision bolts on the same distribution circle are respectively connected with the driving and driven flanges.The diaphragm assembly bears the misalignment of the driving and driven flanges in the form of three-dimensional deformation.The metal diaphragm coupling can compensate various misalignment errors of the connected two shaft systems (radial error, axial error, angular displacement error, error caused by temperature rise), JMI basic type with counterbore The diaphragm coupling mainly relies on the elastic metal diaphragm in the middle of the coupling to transmit the torque between the two shafts. It has the advantages of vibration reduction, no wear, and no maintenance. The ideal product of coupling, the standard implemented by our factory is (JB/T 9147-1999).
Main features of JMI diaphragm coupling
1. The ability to compensate the misalignment of the two axes is strong. Compared with the gear coupling, the angular displacement can be doubled, the reaction force is small during radial displacement, the flexibility is large, and some axial, radial and angular displacements are allowed .
2. It has obvious shock absorption, no noise and no wear.
3. The transmission efficiency is high, up to 99.86%.Especially suitable for medium, high speed and high power transmission.
4. It is suitable for working in high temperature (-80+300) and harsh environment, and can move under shock and vibration conditions.
5. It can accurately transmit the speed without slip, and can be used for the transmission of precision machinery.
