  • Vibration damping device and power transmission device
    Patent number: 8776636
    Abstract: A vibration damping device is equipped with a mass body disposed spaced apart from a rotational center axis of a rotary shaft by a certain distance, and a rolling bearing that rotatably supports the mass body with respect to the rotary shaft and holds a support posture of the mass body with respect to the rotational center axis of the rotary shaft constant.
    Type: Grant
    Filed: March 23, 2009
    Date of Patent: July 15, 2014
    Assignee: Toyota Jidosha Kabushiki Kaisha
    Inventor: Takahiro Mochihara

  • Damper device
    Patent number: 7955212
    Abstract: Mass portions of torsional dampers are annular surrounding corresponding elastic portions. The mass portion of the torsional damper has a first inclined face formed such that the elastic portion deforms in a sheared manner as the mass portion rotates in a rotational direction with respect to a companion flange and the elastic portion partially deforms in a compressed manner as the mass portion rotates in a direction other than the rotational direction. The mass portion of the torsional damper has second inclined faces formed such that the elastic portion deforms in a sheared manner as the mass portion rotates in the direction of the rotational axis of the companion flange and the elastic portion partially deforms in a compressed manner as the mass portion rotates in a direction other than the direction of the rotational axis.
