Disclosed herein is a flexible coupling with a hydraulic vibration damper. The flexible coupling with the hydraulic vibration damper according to an embodiment of the present invention damps torsional vibration of a driving shaft, such as a crank shaft of an engine, reduces vibration and noise of a driven shaft, is easy in manufacturing and installation because it is simple in structure and the damper and the coupling are integrated with each other, enhances economic feasibility and functionality, provides a normal damping function while continuously keeping oil pressure even though oil for damping is not supplied from the outside, and carries out transmission and absorption of torque and absorption of vibration variably. The flexible coupling with the hydraulic vibration damper comprises: a disk-shaped driving structure which has a driving shaft connected to the central portion thereof so as to rotate integrally, an installation space formed between the central portion and the rim portion, and a number of fixing holes formed along the outer circumferential surface of the central portion and the inner circumferential surfaces of the edge portion; a plurality of plate springs radially arranged in the installation space in such a way that both end portions are located at the fixing holes formed in the central portion and the rim of the driving structure; a plurality of inertial masses respectively arranged in divided spaces of the installation space radially formed by the plate spring; a driven shaft connection ring to which the inertia masses are connected and the driven shaft is connected so that the driven shaft is rotated integrally; oil for damping charged in the installation space in which the inertia masses are arranged; and a disk-shaped cover plate connected with the driving structure to prevent a leakage of oil for damping by sealing the installation space in which the inertia masses are arranged. |
