Metal flexible diaphragm coupling (referred to as "diaphragm coupling") is a transmission device that uses metal flexible components to transmit torque without lubrication. It is widely used in ships, aviation, petrochemicals, and machinery. Manufacturing and other fields.The flexible element is a diaphragm group composed of a certain number of thin metal diaphragms from 0.2mm to 0.6mm.When working, the torque is input from the active flange, and the torque is transmitted to the metal diaphragm through the active torque transmission precision bolts arranged along the circumference, and then the diaphragm is transmitted to the driven flange output through the driven precision bolts.

　　It realizes the flexible transmission of the coupling through the elastic deformation of the high-strength alloy diaphragm group, and uses the flexibility of the diaphragm to absorb the relative displacement between the input and output shafts, thereby compensating the various connecting parts of the transmission shaft system due to various factors. Residual misalignment.
