The three advantages of the universal coupling are detailed
1. It has high elasticity (low stiffness, high compliance), the angle of rotation is 10 degrees when the nominal torque is applied, and 25 degrees when the maximum torque is used. It can reduce the natural vibration frequency of the shafting and change the torsional vibration characteristics of the shafting of the diesel engine power unit. Diesel engines do not exhibit dangerous resonance speeds within the required speed range.
2. It has good damping and damping characteristics, can absorb part of the vibration energy, reduce the vibration amplitude when passing the vibration point, and reduce the torsional vibration stress of the shaft section.
3. It can absorb and reduce the fluctuation of the output torque of the diesel engine. For the diesel engine power unit equipped with the reduction gear box, it can reduce the torque on the gear surface and prolong the service life of the gear.
