There are many types of flexible couplings available on the market. Each has its own features and benefits, but all are required to perform a few primary functions: connect two shafts, transmit rotary power and compensate for some shaft misalignment. Elastic couplings are integrally formed metal elastomers, usually cut from metal round rods. Commonly used materials include aluminum alloy, stainless steel, and engineering plastics, which are suitable for various deviations and precise torque transmission.

The flexible tyre coupling adopts tyre body-shaped rubber elements, which are connected with two semi-couplings through bolts to realize torque transmission and displacement compensation, flexible tyre coupling has high elastic performance, small torsional rigidity, strong damping capacity, large axial compensation capacity, and good damping performance.
