The diaphragm coupling is an all-metal flexible coupling.It realizes the flexible transmission of the coupling through the elastic deformation of the thin high-strength alloy steel sheet, so that the coupling can not only absorb the misalignment and shock absorption of the transmission shafts on both sides, but also can be used in other non-metallic components. The coupling is difficult to withstand the high temperature and working under harsh conditions, and obtains a longer service life and better mechanical properties.Its structure is also simple, easy to load and unload, low cost, no need for lubrication and maintenance.These advantages of diaphragm coupling make it widely used in aviation, shipbuilding, petrochemical industry, machinery manufacturing and other fields.
The structure of a metal diaphragm flexible coupling is mainly composed of a metal diaphragm group (diaphragm, half coupling, intermediate section, compression element, bolt, locknut, washer, etc.) is its most common structure.Its working principle is: the torque is input from the half coupling of the active end, and the torque is transmitted to the diaphragm group through the main torsion high-strength bolts arranged at intervals along the circumference, and then the diaphragm group is transmitted to the middle section through the high-strength bolts. , And also transmit torque and motion through the diaphragm set at the other end.The thickness of the diaphragm is generally 0.2mm~0.6mm, and the main shapes of the diaphragm are ring-type spokes, connecting rods, polygons and waist-types.
