An elastic coupling is a mechanical connection device used to transmit torque and rotate. Compared to other connection devices, it is able to reduce shock and vibration through the cushioning effect of elastic materials, and improve transmission stability and reliability. Flexible couplings have simple structure and low maintenance cost, and are widely used in various fields.
An elastic coupling consists of a sleeve, a bearing, an elastic element and a fixed part. Among them, the common materials of elastic elements are rubber, polyurethane, cloth tape, etc. Different elastic elements have different adaptations for various torque transmission needs.
