<P>PROBLEM TO BE SOLVED: To effectively prevent the occurrence of a belt slip, in a rotation variation absorption damper pulley which transmits torque while absorbing a rotation variation. <P>SOLUTION: The rotation variation absorption damper pulley comprises: a hub 1 which is attached to a rotating shaft, and rotates integrally with the rotating shaft; the pulley 4 which is arranged concentrically with the external peripheral side of the hub, and can relatively rotate with the hub 1; a link 7 which is connected to a prescribed point of the hub 1 in the circumferential direction so as to be oscillatory, and oriented toward the forward rotation side of the hub 1 at its oscillation end; and an arm 9 which is connected to the oscillation end of the link 7 so as to be oscillatory, circularly extends to the forward rotation side of the hub 1, and is closely connected to the inner peripheral surface of the pulley 4 at its outer peripheral surface so as to be oscillatory. A friction force of the arm 9 to the inner peripheral surface of the pulley 4 is increased by the link 7 at the retardancy differentiation of the pulley 4 with respect to the hub 1, and at the advance differentiation of the pulley 4 with respect to the hub 1, the friction force of the arm 9 to the inner peripheral surface of the pulley 4 is decreased by the link 7. <P>COPYRIGHT: (C)2013,JPO&INPIT |
