• Specification

• Function and Application

1.Power transmission: The coupling is responsible for transmitting the power of the engine to the hydraulic pump, driving the entire hydraulic system to operate. Only when the coupling can stably and efficiently transmit rotational force (torque) can the excavator's various working devices, such as the boom, arm, and bucket, perform actions smoothly.

2.Absorbing misalignment: During the operation of the excavator, due to factors such as equipment vibration and installation errors, there may be slight misalignments between the engine and the hydraulic pump shafts. The coupling can absorb these misalignments to a certain extent, reducing the additional stress and wear caused by misalignments on the shafts and other components, thereby prolonging the service life of the equipment.

3.Shock absorption and vibration reduction: The working environment of the excavator is often very harsh, and it will be affected by various impact forces and vibrations during operation. The coupling can soften the vibrations from the engine and absorb the shock load during the operation of the hydraulic system, reducing the impact of vibrations and shocks on the entire equipment, improving the stability and reliability of the equipment operation, and also reducing the occurrence of faults caused by vibrations and shocks.
