<p><P>PROBLEM TO BE SOLVED: To effectively prevent belt squealing due to belt slipping or misalignment in a rotational fluctuation absorption damper pulley for transmitting torque while absorbing rotational fluctuation. <P>SOLUTION: The rotational fluctuation absorption damper pulley includes an inner peripheral member 3, and a pulley body 5 disposed on its outer circumferential side to be rotated and displaced in an axial direction relatively to the inner peripheral member 3 and having a groove 52 formed on its outer circumferential surface to allow a transmission belt to be wound thereon. A pair of flanges 32 and 33 are formed in the inner peripheral member 3 to face the pulley body 5 from both sides of its axial direction. Spring clutches 6 and 7 are arranged between the flanges 32 and 33 and the facing ends of the pulley body 5. The spring clutches 6 and 7 have axial ends 6a and 7a fixed to the inner peripheral member 3 side, and have the other axial ends 6b and 7b not fixed. When the pulley body 5 is delayed with respect to the forward rotation of the inner peripheral member 3, the belt is wound into a coil in a diameter-increasing direction by a frictional force with the pulley body 5 side. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
