Title:
CENTRIFUGAL PENDULUM TYPE VIBRATION DAMPER
Document Type and Number:
Japanese Patent JP3468874
Kind Code:
B2
Abstract:
PURPOSE: To prevent noise from being generated by collision of a roller, and manufacture a vibration damper in a low cost.
CONSTITUTION: A vibration damper main body is constituted by a connecting plate 11 and annular plates 12, 13 which are connected to both sides of the connecting plate 11. The recessed guide part of a rolling chamber 16 is constituted by the relief hole 15 of the connecting plate 11 and guide holes 14 of the annular plates 12, 13. The annular projection part 18 of a roller 17 is fit to the recessed guide part of the rolling chamber 16. An annular groove 19 is formed on the top surface of the annular projection part 18, and a rubber ring 20 is fit to the annular groove 19. Torsion vibration in a power transmitting system is reduced by resonance vibration of the roller 17. When the roller 17 is rotated at a setting angle or more, the annular projection part 18 of the roller 17 collides with the wall surface of the relief hole 15 through the rubber ring 20. Shock of collision is released by the rubber ring 20. It is possible to install the rubber ring 20 on the roller 17 by only fitting the rubber ring 20 to the annular groove 19.
