MASS DAMPER
PROBLEM TO BE SOLVED: To provide a mass damper in which manufacturing cost can be reduced through reduction of the number of component elements, rotary inertia mass of a rotating mass can be easily adjusted and its size can be made compact.SOLUTION: A screw shaft 4a is movably stored at one location of a cylindrical main body part 2 integral with a rotary mass, a nut 4c engaged in thread with the screw shaft 4a is attached, a rod 3 is movably stored at the other location of the main body part 2 to support the main body part 2 in a rotatable manner. Each of a pair of thrust bearings 7L, 7R is arranged at both sides of an axial line direction of a flange 6 integral with the rod 3. Each of a pair of disc spring units 8L, 8R composed of a plurality of stacked disc springs 8a is arranged between a flange 6 and one thrust bearing 7L and between the flange and the other thrust bearing 7R, a relative displacement between the first location and the second location accompanied by vibration of a structure is transmitted to the main body part 2 under its state converted into a rotating motion, the main body part 2 and the rotating mass are rotated and the disc spring units 8L (8R) are pushed in an axial line direction.SELECTED DRAWING: Figure 1
【課題】部品点数の削減により製造コストを削減でき、回転マスの回転慣性質量を容易に調整できるとともに、小型化を図れるマスダンパを提供する。【解決手段】回転マスと一体の筒状の本体部2の一方の部位に、ねじ軸4aが移動可能に収容され、ねじ軸4aに螺合するナット4cが取り付けられており、ロッド3が、本体部2の他方の部位に移動可能に収容され、本体部2を回転可能に支持している。ロッド3と一体のフランジ6の軸線方向の両側に、一対のスラスト軸受け7L,7Rがそれぞれ配置され、積層された複数の皿ばね8aから成る一対の皿ばねユニット8L,8Rが、フランジ6と一方のスラスト軸受け7Lとの間及びフランジと他方のスラスト軸受け7Rとの間に、それぞれ配置されており、構造物の振動に伴う第１及び第２部位の間の相対変位が、回転運動に変換された状態で本体部2に伝達され、本体部2及び回転マスが回転し、皿ばねユニット8L(8R)が軸線方向に押圧される。【選択図】図１
