Abstract

PURPOSE:To accomplish the optimum tuning and to effectively prevent torsional vibration by connecting a damper inertia body to a rotor through an elastic body and providing an adjust bolt for moving the damper inertia body in the radial direction. CONSTITUTION:A damper inertia body 1 is connected to a fixing hub 6 through a damper rubber 5. A slide piece 4 is screw-engaged with an adjust bolt 2. The damper elastic body 2 is moved in the radial direction along a slide groove 8 by turning the adjust bolt 2. The magnitude of damper inertia moment is in proportion to the square of a slide radius. Thus, the optimum tuning can be accomplished so as to effectively prevent torsional vibration.

みを防止できる。In such a device, the sliding piece 4 is threadedly engaged with the adjusting bolt 2, and by turning the adjusting bolt 2, the damper inertial body 2 moves in the radial direction along the sliding groove 8. Therefore, the damper moment of inertia can be made variable. Since the magnitude of the damper moment of inertia is proportional to the square of the slide radius, it is possible to properly tune the damper. After tuning the damper, loosening can be prevented by connecting each adjustment bolt 2 to the locking hole 7 with a wire or the like.
