A torsional vibration damper (1) includes a boss member (5) and a disk plate (7, 8) provided coaxially with each other; an elastic member (4) provided between the boss member (5) and the disk plate (7, 8) and being elastically deformable in a rotation direction of the boss member (5); a cam member (6) provided coaxially with the boss member (5) and rotating integrally with the boss member (5); a torque transmission member (19) coming in contact with a cam surface (6a) of the cam member (6) and transmitting rotation torque between the boss member (5) and the disk plate (7, 8); and a socket member (16) provided between the torque transmission member (19) and the elastic member (4), holding one end (4a) of the elastic member (4) and having a contact surface (16a) coming in contact with the torque transmission member (19). The torque transmission member (19) is provided to be capable of entirely reciprocating in a radial direction of the boss member (5) in accordance with rotation of the cam member (6), and elastically compresses the elastic member (4) in the rotation direction when it moves outward in the radial direction of the boss member (5).

摘要： A torsional vibration damper, for example for damping lead lag vibrations in the blades of a helicopter tail rotor, comprises a damping unit having first and second members (20, 22) which are rotatable relatively to one another about a central axis (12). The first member (20) carries cam blocks (30) provided with cam follower surfaces (42, 44, 46, 48). The cam follower surfaces (42, 44, 46, 48) are contacted by contact faces (70, 72, 74, 76) on flexible fingers (38, 40). Relative rotational movement between the first and second members (20, 22) is accompanied by displacement of the contact faces (70, 72, 74, 76) over the cam follower surfaces (42, 44, 46, 48) and resulting deflection of the fingers (38, 40). The resulting frictional forces and bending stresses serve to damp lead lag blade oscillations.

摘要： A damper apparatus includes a valve body 10 that opens and closes a through hole 3d that communicates a first chamber 6A with a second chamber 6B according to a movement of a piston 4 disposed in a receiving hole 2a, the piston 4 including an annular fitting recess 4i formed in an outer peripheral surface of the piston 4, the fitting recess 4i receiving a seal member 11. A width of the fitting recess 4i is sized to be greater than a diameter of a cord member constituting the seal member 11, thereby allowing the seal member 11 to be moved in the fitting recess 4i in the width direction of the fitting recess 4i. When the seal member 11 is positioned in an end portion of the fitting recess 4i in the second chamber 6B side, a friction resistance generated between an outer peripheral portion of the seal member 11 and an inner peripheral surface of the receiving hole 2a is greater than a friction resistance generated between an inner peripheral portion of the seal member 11 and a bottom surface of the fitting recess 4i.

摘要： The invention relates to a vibration damper for a clutch friction disc (1) including: an input element and an output element, rotatably movable relative to one another about an axis of rotation X; damping means for transmitting a torque and damping the rotational deviations between the input and output elements; the input element including two flanges (12, 13), fixed to one another for conjoint rotary movement, arranged on either side of the damping means and thus defining a cassette for housing said damping means; the damping means comprising a resilient blade (22), fixed to one of said input and output elements for rotation therewith, and provided with a cam surface (23). The damper comprises a cam follower (24), supported by the other one of said input and output elements, and arranged such as to engage with said cam surface (23). The cam surface (23) is arranged such that, for an angular displacement between the input element and the output element relative to an angular rest position, the cam follower (24) exerts a bending force on the resilient blade (22) producing a reaction force capable of returning said input and output elements towards said angular rest position.

摘要： The invention relates to a vibration damper for a torque transmission device including a first element (1) and a second element (2) that are rotatable relative to one another around an axis of rotation X; and damping means to transmit a torque and damp the rotational acyclisms between the first element (1) and the second element (2). The damping means include an elastic blade (4), mounted secured to the first element and provided with a cam surface (6); and the damper includes a cam follower (5), supported by the second element, and arranged to cooperate with said cam surface (6). The cam surface (6) is arranged such that, for an angular travel between the first element (1) and the second element (2) relative to an angular idle position, the cam follower (6) exerts a bending force on the elastic blade (4) producing a reaction force capable of recalling said first (1) and second (2) elements toward said angular idle position.
