Keyway Connecting Single Diaphragm Coupling Supplier

Keyway Connecting Single Diaphragm Coupling Supplier

Several sets of diaphragms (stainless steel sheets) are staggeredly connected to the two half-couplings. Each set of diaphragms is made up of several stacks, and the diaphragms are divided into connecting rods and whole shapes of different shapes. The diaphragm coupling relies on the elastic deformation of the diaphragm to compensate the relative displacement of the two coupled shafts. It is a high-performance flexible coupling of metal strong components. It does not need oil, and has a compact structure, high strength and long service life. , No rotation gap, not affected by temperature and oil pollution. It has the characteristics of acid resistance, alkali resistance and corrosion resistance. It is suitable for high-speed, high-speed, and corrosive media working conditions.

The diaphragm coupling can compensate the axial, radial, and angular offsets between the master and the slave due to manufacturing errors, installation errors, load deformation, and the effects of temperature rise changes. Diaphragm coupling is a metal elastic element flexible coupling. It relies on the metal coupling diaphragm to connect the master and slave motors to transmit torque. Ideal for universal couplings and general couplings.
