REVOLVING SPEED ADAPTIVE VIBRATION ABSORBER

摘要

PROBLEM TO BE SOLVED: To provide an improve revolving speed dependence type vibration absorber which avoids the reduction of vibration absorbing action in a vibration frequency of wide range and is capable of absorbing a rotational vibration of small amplitude. SOLUTION: This revolving speed adaptive vibration absorber is one that has a hub part 2 and has a plurality of inertia bodies 3 adjacent in a peripheral direction and movable on a curve track in the hub part 2, and has the curve track approaching an axial line on both sides in peripheral direction so as to change a space in a radial direction between the inertia body 3 and the axial line 1 when rotational vibration is generated. In addition, at least one relatively turnable balance ring 4 is elastically supported on the hub part 2.
