Flexible Coupling CNC Plum Shaft Coupling

Several sets of diaphragms (stainless steel sheets) are alternately bolted to the two coupling halves, and each set of diaphragms is formed by stacking several pieces, and the diaphragm is divided into a link type and a whole shape of different shapes. The diaphragm coupling relies on the elastic deformation of the diaphragm to compensate the relative displacement of the two shafts. It is a high-performance flexible coupling for metal strong components. It does not need oil, has a compact structure, high strength and long service life. It has no rotating gap, is not affected by temperature and oil pollution, and has the characteristics of acid resistance, alkali resistance and corrosion resistance. It is suitable for shafting transmission in high temperature, high speed and corrosive medium working conditions.

Product Details

The diaphragm coupling compensates for axial, radial and angular offsets between the active machine and the driven machine due to manufacturing tolerances, mounting errors, load bearing deformations, and changes in temperature rise. The diaphragm coupling is a flexible coupling of metal elastic element, which relies on the metal coupling diaphragm to connect the main and the slave to transmit torque. It has the advantages of elastic vibration reduction, no noise and no lubrication, and is a substitute tooth today. Ideal for couplings and general couplings

The ML type plum blossom elastic coupling is composed of two semi-couplings and elastic elements with the same shape of the claws, and the plum-shaped element is placed between the two halves of the coupling claws to realize the coupling of the two halves. connection. The utility model has the characteristics of compensating the relative offset of the two axes, damping, buffering, small radial rule, simple structure, high lubrication bearing capacity, convenient maintenance, etc., but the two halves of the coupling need to move in the axial direction when the elastic element is changed. It is suitable for connecting two coaxial lines, frequent starting, positive and negative rotation change, medium speed low, medium and small power transmission shaft system requiring high working reliability.
