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 bush pin type flexible coupling is a type of power transmission mechanical coupling used to connect two shafts together at their ends for the purpose of transmitting power.

The pin gear coupling is designed with non-metallic flexible pin, two toothed semi-couplings and a toothed sleeve ring with an outer ring. It uses non-metallic flexible deformation to transfer torque and cushion shock and compensate angular displacement.

The flexible pin coupling is a basic transmission parts that has simple structure, needs no lubrication, and is easy to manufacture, install and disassemble the flexible pin. It uses two semi-couplings with flange holes and a non-metallic flexible pin for crane to transmit torque, suitable for low-to-medium speed and low-to-medium torque occasions.

The design of the elastic sleeve pin coupling is simple and clever in design and has wide applicability. It uses the pin with elastic sleeve to connect two semi-couplings with pin holes to realize torque transmission and larger angular compensation. At the same time, it has good shock absorption and buffering performance, which can be used in high-speed occasions without lubrication and requiring easy pin sleeve replacement.
