<p><P>PROBLEM TO BE SOLVED: To effectively prevent the occurrence of belt slipping in a rotational fluctuation absorbing damper pulley for transmitting torque while absorbing rotational fluctuation. <P>SOLUTION: The rotational fluctuation absorbing pulley includes a hub 1 attached to a rotary shaft to be rotated integrally with the rotary shaft, a pulley 4 concentrically disposed on its outer circumferential side, an elastic body 10 integrally disposed in the inner peripheral surface of the pulley 4, a link 7 coupled with the circumferential-direction prescribed place of the hub 1 to swing, and an arm 9 coupled with the swing end of the link 7 to swing and extend in a circular arc shape toward the forward rotation side of the hub 1. In the prescribed place of the inner peripheral surface of the elastic body 10, an engaging part 10a is formed to be engaged with the tip part 9b of the arm 9 only during the delay angle difference of the pulley 4 to the hub 1, and the arm 9 is displaceable in a radial direction in the compression direction of the elastic body 10 by rocking of the link 7. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
