VIBRATION DAMPING DEVICE AND VIBRATION DAMPING STRUCTURE
To provide a vibration damping device which solves problems of conventional techniques, that is, can cope with a variety of vibration patterns, and can suppress the vibration of an object without obtaining a reaction force from a fixed support, and a vibration damping structure having the vibration damping device installed at the object.SOLUTION: This vibration damping device comprises a weight, a weight spring, a screw columnar support, a rotating body and a support. The rotating body is attached to the screw columnar support by the screwing of a screw arranged at an internal periphery of the rotating body to an external periphery of the screw columnar support, and one end of the screw columnar support is fixed to the weight so as to constrict the rotation of the screw columnar support around a shaft of the columnar support. When an object vibrates, relative acceleration is generated between the weight and the object, so that the screw columnar support relatively moves in an axial direction with respect to the rotating body, and the rotating body rotates around the shaft of the screw columnar support.SELECTED DRAWING: Figure 2
【課題】本願発明の課題は、従来技術が抱える問題を解決することであり、すなわち多様な揺れのパターンに対応することができ、しかも固定支持物から反力を得ることなく、対象物の振動を抑制することができる制振装置と、これを対象物に設置した制振構造を提供することである。【解決手段】本願発明の制振装置は、重錘と重錘用ばね、ネジ支柱、回転体、支持体を備えたものである。回転体はその内周に設けられたネジがネジ支柱の外周に螺合することでネジ支柱に取り付けられ、ネジ支柱の軸周りの回転を拘束するようにネジ支柱の一端が重錘に固定される。対象物が振動すると、重錘と対象物との間に相対加速度が生じ、これに伴ってネジ支柱が回転体に対して相対的に軸方向に移動し、回転体がネジ支柱の軸周りに回転する。【選択図】図２
