Features of elastic coupling

The elastic coupling is vulcanized and bonded to the circular metal assembly by using rubber, and is connected with the two halves of the coupling by bolts.The name before the revision of the standard was high elastic rubber coupling.

Features of elastic pin coupling:

1. It has high elasticity (low rigidity, large flexibility), the rotation angle is 10 degrees when bearing the nominal torque, and 25 degrees when the torque is applied. It can reduce the natural vibration frequency of the shaft system and change the torsional vibration characteristics of the diesel engine power unit shaft system. So that the diesel engine does not appear dangerous resonance speed within the required speed range.

2. It 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.

3. 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 impact on the gear surface when the torque is changed, and prolong the service life of the gear.

4. It can compensate the axis deviation. It is not only highly elastic in torsion, but also elastic in axial, radial and angular directions. It is easier to center during installation, and can compensate for errors caused by the deformation of the hull and base after installation. , To ensure the normal operation of the diesel engine and shafting.

5. It can reduce the vibration of the machine base and isolate the structure-borne sound and insulation current.After the diesel engine is equipped with a shock-absorbing base, relative vibration occurs between it and the shaft system. Only when an elastic ring coupling with elasticity in the axial, radial and angular directions is installed, can the reducer be installed under the main engine. Vibrate the machine base, and at the same time isolate solid-borne sound and reduce noise.Because the elastic ring coupling uses rubber components, it has good insulation performance and can prevent axial current.
