Flexible Double Diaphragm Coupling

Flexible Double Diaphragm Coupling

The double diaphragm coupling is composed of several sets of diaphragms (stainless steel sheets) staggeredly connected to the two half couplings. Each set of diaphragms is composed of several stacks. The diaphragms are divided into connecting rods and different shapes.

Product Details

The dual 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 elastic elements. It does not require lubrication, has a compact structure, high strength, and a long service life. , No rotation gap, not affected by temperature and oil pollution. It has the characteristics of acid resistance, alkali resistance and anti-corrosion. It is suitable for high-speed, high-speed, and corrosive media working conditions. It is widely used in various mechanical devices. Transmissions, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopter), high-speed power for ships Transmission system, steam turbine piston power mechanical transmission system
