  • Dynamic vibration absorbing device and fluid coupling
    Patent number: 10473184
    Abstract: A dynamic vibration absorbing device includes a tubular member having an annular shape. The dynamic vibration absorbing device also includes at least one elastic member disposed inside the tubular member so as to be non-rotatable relatively to the tubular member. The dynamic vibration absorbing device further includes at least one mass body disposed inside the tubular member so as to be rotatable relatively to the tubular member.
    Type: Grant
    Filed: February 9, 2016
    Date of Patent: November 12, 2019
    Assignee: EXEDY CORPORATION

  • Dynamic vibration absorbing device and fluid coupling
    Patent number: 10422408
    Abstract: A dynamic vibration absorbing device inhibits fluctuations in rotational velocity of a rotary member. The dynamic vibration absorbing device includes a tubular member having an annular shape, the tubular member including a slit extending in a circumferential direction. The dynamic vibration absorbing device also includes at least one elastic member disposed inside the tubular member, the at least one elastic member disposed to be non-rotatable relatively to the tubular member. In addition, the dynamic vibration absorbing device includes a support member including an attachment part, a support part and a coupling part, the attachment part attachable to the rotary member, the support part disposed inside the tubular member, the support part disposed to be rotatable relatively to the tubular member, the coupling part coupling the attachment part and the support part through the slit.

  • Dynamic vibration absorbing device and fluid coupling
    Patent number: 10281002
    Abstract: A dynamic vibration absorbing device includes a guide member having an annular shape. The dynamic vibration absorbing device also includes at least one mass body that rolls along the guide member. In addition, the dynamic vibration absorbing device includes at least one elastic member non-rotatable relatively to the guide member, the at least one elastic member disposed to restrict the at least one mass body from rotating relatively to the guide member.
