Title:
TORSIONAL VIBRATION REDUCTION DEVICE
Document Type and Number:
Japanese Patent JP2020091013
Kind Code:
A
Abstract:
To provide a torsional vibration reduction device which can suppress the generation of noise by generating a core alignment action even if a rotation number of a rotating body is low.SOLUTION: In a torsional vibration reduction device for reducing the vibration of torque in which an inertia mass body 1 relatively rotates with respect to a rotating body 6 due to the reciprocation of rolling bodies 3 along rolling faces 4 by the vibration of the torque in a state that the rolling bodies 3 are pressed to the rolling faces 4 by a centrifugal force, inner wall faces out of the inner wall faces of guide holes 2 located at the inside of the rolling faces 4 in a radial direction, being both sides of the rolling faces 4 in a circumferential direction of the inertial mass body 1 are made to be guide faces 5 for generating component forces C2 for pressing the inertia mass body 1 to the circumferential direction by making the rolling bodies 3 pressed to the outside in the radial direction by the centrifugal force contact therewith.SELECTED DRAWING: Figure 4
