捩り振動減衰装置
Document Type and Number:
Japanese Patent JP5664804
Kind Code:
B2
Abstract:
A torsional vibration damping device that can ensure a space for allowing a mass body to make reciprocating movements and can improve the vibration damping performance is provided. A torsional vibration damping device 1 in which a mass body 3 is attached to a rotating body 2 by two support pins 5R and 5L includes two first hollow portions 4 which are formed in the rotating body 2 at positions corresponding to the respective support pins 5R and 5L and into which the respective support pins 5R and 5L are inserted, and two second hollow portions 7 which are formed in the mass body 3 at positions opposed to the respective first hollow portions 4 and into which the respective support pins 5R and 5L are inserted. Outer sides of inner peripheral edges of respective the first hollow portions 4 in a radial direction of the rotating body 2 serve as guide faces 6R and 6L. Inner sides of inner peripheral edges of the respective second hollow portions 7 in the radial direction of the rotating body 2 serve as attachment faces 8R and 8L. The guide faces 6R and 6L and the attachment faces 8R and 8L are formed as recessed curved faces. A distance D 1 between centers O 1 of curvature of the guide faces 6R and 6L is shorter than a distance D 2 between centers O 2 of curvature of the attachment faces 8R and 8L.
