DAMPING DEVICE |
| 摘要 |
The damping device includes: a fixed cylinder that is configured to be fixed to a first structural body and formed into a cylindrical shape so as to comprise a hollow portion; a shaft member that is configured to be fixed to a second structural body, the shaft member being housed in the hollow portion of the fixed cylinder and having an outer peripheral surface provided with a helical thread groove; a nut member that is threadedly engaged with the shaft member, and converts an axial motion of the shaft member into a rotational motion; a rotor member that is formed into a cylindrical shape so as to cover the fixed cylinder and to form a cylindrical accommodation chamber between the rotor member and an outer peripheral surface of the fixed cylinder, and is rotated by the nut member; and viscous fluid that is sealed in the cylindrical accommodation chamber. |

1. A damping device, comprising:
a fixed cylinder that is configured to be fixed to a first structural body and formed into a cylindrical shape so as to comprise a hollow portion; a shaft member that is configured to be fixed to a second structural body, the shaft member being housed in the hollow portion of the fixed cylinder and having an outer peripheral surface provided with a helical thread groove; a nut member that is threadedly engaged with the shaft member, and converts an axial motion of the shaft member into a rotational motion; a rotor member that is formed into a cylindrical shape so as to cover the fixed cylinder and to form a cylindrical accommodation chamber between the rotor member and an outer peripheral surface of the fixed cylinder, and is rotated by the nut member; and viscous fluid that is sealed in the cylindrical accommodation chamber. |
