Divided into two categories, spiral groove type and parallel groove type. It can be widely used in the transmission shaft end connection of large equipment such as steel rolling, lifting, forging, petroleum and other various mechanical equipment. The reducing flexible grooved coupling has good damping and vibration reduction characteristics, which can absorb part of the vibration energy, reduce the vibration amplitude when passing through the vibration point, and reduce the torsional vibration stress of the shaft section. It can absorb and reduce the fluctuation of the output torque of the diesel engine. For the diesel engine power unit equipped with a reduction gear box, it can reduce the knock on the gear surface when the torque is fluctuating, and prolong the service life of the gear.
