Abstract
According to an embodiment, a damping device includes a base member including a first base and a second base, a weight member, a pair of first base-side coil springs provided between the first base and the weight member, and a pair of second base-side coil springs provided between the second base and the weight member. Each of the first base-side coil springs includes a first effective turn portion, a first fixed pin portion supported in the first base, and a first movable pin portion supported in the weight member. Each of the second base-side coil springs includes a second effective turn portion, a second fixed pin portion supported in the second base, and a second movable pin portion supported in the weight member.
Claims13
A damping device arranged in a vibration suppression target, the damping device comprising:
- a base member comprising a first base and a second base facing each other, the base member being fixed to the vibration suppression target;
- a weight member provided between the first base and the second base;
- a first spring assembly comprising at least two first base-side coil springs provided in a compressed state between the first base and the weight member, each of the first base-side coil springs comprising:
- a helical first effective turn portion which deforms in a direction along a first axis;
- a first fixed pin portion which extends from one end of the first effective turn portion in the direction along the first axis and is connected to the first base;
- and
- a first movable pin portion which extends from the other end of the first effective turn portion in the direction along the first axis and is connected to the weight member;
- and
- a second spring assembly comprising at least two second base-side coil springs provided in a compressed state between the second base and the weight member, each of the second base-side coil springs comprising:
- a helical second effective turn portion which deforms in a direction along a second axis;
- a second fixed pin portion which extends from one end of the second effective turn portion in the direction along the second axis and is connected to the second base;
- and
- a second movable pin portion which extends from the other end of the second effective turn portion in the direction along the second axis and is connected to the weight member.
