Title (EN) EDDY CURRENT DAMPER
(FR) INSTRUMENT À COURANT DE FOUCAULT
(JA) 渦電流式ダンパ
Abstract:
(EN) An eddy current damper (1) includes a screw shaft (7), a plurality of first permanent magnets (3), a plurality of second permanent magnets (4), a cylindrical magnet holding member (2), a conductive member (5) having conductivity and a cylindrical shape, and a ball nut (6) engaged with the screw shaft (7). The screw shaft (7) is movable in the axial direction. The first permanent magnets (3) are arrayed along the circumferential direction around the screw shaft (7). The second permanent magnets (4) are disposed between the first permanent magnets (3), leaving gaps with the first permanent magnets (3), and dispositions of magnetic poles are inverted between the first permanent magnets (3) and the second permanent magnets (4). The magnet holding member (2) holds the first permanent magnets (3) and the second permanent magnets (4). The conductive member (5) opposes the first permanent magnets (3) and the second permanent magnets (4), leaving gaps with the first permanent magnets (3) and the second permanent magnets (4). The ball nut (6) is disposed in the magnet holding member (2) and the conductive member (5), and is fixed to the magnet holding member (2) or the conductive member (5).
(FR) Amortisseur à courant de Foucault (1) comprenant un arbre de vis (7), une pluralité de premiers aimants permanents (3), une pluralité de seconds aimants permanents (4), un élément de maintien d'aimant cylindrique (2), un élément conducteur (5) ayant une conductivité et une forme cylindrique, et un écrou sphérique (6) en prise avec l'arbre de vis (7). L'arbre de vis (7) est mobile dans la direction axiale. Les premiers aimants permanents (3) sont déployés le long de la direction circonférentielle autour de l'arbre de vis (7). Les seconds aimants permanents (4) sont disposés entre les premiers aimants permanents (3), laissant des espaces avec les premiers aimants permanents (3), et des dispositions de pôles magnétiques sont inversées entre les premiers aimants permanents (3) et les seconds aimants permanents (4). L'élément de maintien d'aimant (2) maintient les premiers aimants permanents (3) et les seconds aimants permanents (4). L'élément conducteur (5) s'oppose aux premiers aimants permanents (3) et aux seconds aimants permanents (4), laissant des espaces avec les premiers aimants permanents (3) et les seconds aimants permanents (4). L'écrou sphérique (6) est disposé dans l'élément de maintien d'aimant (2) et l'élément conducteur (5), et est fixé à l'élément de maintien d'aimant (2) ou à l'élément conducteur (5).
(JA) 渦電流式ダンパ(1)は、ねじ軸(7)と、複数の第1永久磁石(3)と、複数の第2永久磁石(4)と、円筒形状の磁石保持部材(2)と、導電性を有する円筒形状の導電部材(5)と、ねじ軸(7)と噛み合うボールナット(6)と、を含む。ねじ軸(7)は軸方向に移動可能である。第1永久磁石(3)は、ねじ軸(7)の周りに円周方向に沿って配列される。第2永久磁石(4)は、第1永久磁石(3)同士の間に第1永久磁石(3)と隙間を空けて配置され、第1永久磁石(3)と磁極の配置が反転する。磁石保持部材(2)は、第1永久磁石(3)及び第2永久磁石(4)を保持する。導電部材(5)は、第1永久磁石(3)及び第2永久磁石(4)と隙間を空けて対向する。ボールナット(6)は、磁石保持部材(2)及び導電部材(5)の内部に配置されて磁石保持部材(2)又は導電部材(5)に固定される。
