LINEAR ROLLING BEARING
PROBLEM TO BE SOLVED: To provide a linear rolling bearing capable of obtaining proper vibration suppression effect, according to an earthquake motion or structure.SOLUTION: A linear rolling bearing has a piezoelectric element member where an intermediate plate structure is formed into a tabular contour, and in the contour a plurality of piezoelectric elements is arrayed. An electric circuit is electrically connected to a pair of electrodes of the plurality of piezoelectric elements in the intermediate plate structure. When a tabular thickness of the piezoelectric element member in the intermediate structure changes, potential difference between the pair of electrodes of the piezoelectric element occurs. When it is determined that an earthquake occurs, the electric circuit applies voltage to the pair of electrodes of the piezoelectric element in the intermediate structure, according to degree of unevenness occurring between the linear rolling bearing and another bearing for supporting a structure, thereby changing the tabular thickness of the piezoelectric element member in the intermediate plate structure.SELECTED DRAWING: Figure 1
【課題】 地震動や建造物に応じて適切な振動抑制効果が得られる直動転がり支承を提供しようとする。【解決手段】従来の直動転がり支承にかわって、前記中間板構造が板状の輪郭を形成し該輪郭の中に整列する複数の圧電素子をもつ圧電素子部材を有し、前記電気回路が前記中間板構造の複数の該圧電素子の一対の電極に電気的に接続され、前記中間板構造の前記圧電素子部材の板状の厚みが変化すると前記中間板構造の前記圧電素子の一対の電極に電位差が生じ、地震が発生したと判断したとき、構造物を支持する他の支承との間に発生した不陸の程度に応じて前記電気回路が前記中間板構造の前記圧電素子の一対の電極に電圧を印可して前記中間板構造の前記圧電素子部材の板状の厚みを変化させる。【選択図】 図１
