MASS DAMPER
PROBLEM TO BE SOLVED: To provide a mass damper capable of adjusting dynamic characteristic or vibration characteristic with a simple structure.SOLUTION: A mass damper including a linear motion shaft having a male screw of a screw feeding direction along a displacement direction in linear displacement, a rotary member disposed on a female screw engaged with the male screw, a flywheel member as a member capable of rotating interlockingly with rotation of the rotary member, and a frame respectively rotatably supporting a transmission limiting member as a member for limiting torque transmittable between the rotary member and the flywheel member, the rotary member, and the flywheel member. The transmission limiting member has a friction member kept into contact with the rotary member and generating frictional force, an actuator supported by the flywheel member to press the friction member to a first member with prescribed pressing force, and a control device for controlling the actuator.SELECTED DRAWING: Figure 1
【課題】 簡易な構造により動特性または振動特性を調整できるマスダンパーを提供しようとする。【解決手段】従来のマスダンパーにかわって、直動変位の変位方向に沿ってねじ送り方向を向けた雄ねじを設けられた直動軸と、前記雄ねじに嵌めあう雌ねじを設けられた回転部材と、前記回転部材の回転に連動して回転できる部材であるフライホイール部材と、前記回転部材と前記フライホイール部材の間での伝達可能なトルクを制限できる部材である伝達制限部材と前記回転部材と前記フライホイール部材とを回転自在に各々に支持するフレームと、を備え、前記伝達制限部材が、前記回転部材に接触し摩擦力を発生する摩擦部材と、前記フライホイール部材に支持されて前記摩擦部材を前記第一部材に所定の押付け力で押付けるアクチエータと、前記アクチエータを制御する制御装置と、を有する、ものとした。【選択図】 図１
