TORSIONAL VIBRATION DAMPING DEVICE |
摘要 |
<p>A torsional vibration damping device in which a first rolling contact surface that is curved with a center of curvature at a location offset from a rotation center of a rotating body, which rotates upon receiving a torque, is formed along a circumferential direction of the rotating body at a location offset from the rotation center of the rotating body in a radial direction, and which includes the rolling element that is brought into contact with the first rolling contact surface by receiving a centrifugal force resulting from rotation with the rotating body and that rolls along the first rolling contact surface through torsional vibrations of the rotating body is described. The rolling element includes a first rolling element that rolls along the first rolling contact surface and that is formed in a hollow shape, and a second rolling element that is arranged inside the first rolling element such that the second rolling element rolls along a second rolling contact surface formed inside the first rolling element.</p> |
