The difference between diaphragm coupling and plum coupling

　　The diaphragm coupling is a flexible coupling with a metal elastic element. It relies on the metal coupling diaphragm to connect the main and driven machines to transmit torque. It has the advantages of elastic vibration damping, no noise, and no need for lubrication.The diaphragm coupling can compensate for the axial, radial and angular deviations between the active machine and the driven machine due to manufacturing errors, installation errors, load-bearing deformations and the effects of temperature rise changes.

　　The plum blossom coupling works stably and reliably, has good damping, cushioning and electrical insulation properties, simple structure, small radial size, light weight, and small moment of inertia, suitable for medium and high speed applications.Simple structure, no lubrication, convenient maintenance, easy inspection, maintenance-free, and can run continuously for a long time.The high-strength polyurethane elastic elements are wear-resistant and oil-resistant, have large carrying capacity, long service life, and reliability.
