Background
In large-scale structure and large torque transmission equipment, a multi-friction plate hydraulic clutch is generally adopted. The current hydraulic clutches are mainly of two types: 1. the shell is fixed, oil is supplied by the shell, and the size of the structure is limited due to the relation between sealing and linear speed, so that the requirement of large torque is difficult to achieve; 2. the shaft end oil supply structure can achieve large torque, but because the oil duct needs to be processed at the center of the shaft, the installation of the clutch in the long shaft is limited, and meanwhile, if the shaft diameter is large and the rotating speed is high, the linear speed of the sealing ring of the shaft end oil supply structure is high, and the practical requirement is difficult to meet. Furthermore, if the driven member is to be moved in the axial direction by a short distance, e.g. 10-20mm, when it is disengaged, the current clutch is difficult to solve effectively.
