description | To provide an eddy current damper capable easily adjusting attenuation force.SOLUTION: An eddy current damper 1 comprises a screw shaft 7, a plurality of magnet holding rings 2, a plurality of first permanent magnets 3, a plurality of second permanent magnets 4, a plurality of conductive rings 5, and a ball nut 6 engaged to the screw shaft 7. The plurality of magnet holding rings 2 are connected to the screw shaft 7 in an axis direction. The plurality of first magnets 3 are respectively held in the plurality of magnet holding rings 2. The plurality of first magnets 3 are each arrayed along a circumferential direction of the magnet holding ring 2. The plurality of second magnets 4 are respectively held in the plurality of magnet holding rings 2. The plurality of second magnets 4 are each arranged between first magnets 3, and a magnetic pole thereof is arranged inversely to that of the first magnet 3. The plurality of conductive rings 5 each has conductivity, and is opposite to the first magnet 3 and the second magnet 4 at intervals. The ball nut 6 is arranged in the magnet holding ring 2 and the conductive ring 5, and fixed to the magnet holding ring 2.SELECTED DRAWING: Figure 2
【課題】減衰力の調整を容易に行える渦電流式ダンパを提供する。【解決手段】渦電流式ダンパ1は、ねじ軸7と、複数の磁石保持リング2と、複数の第1永久磁石3と、複数の第2永久磁石4と、複数の導電リング5と、ねじ軸7と噛み合うボールナット6と、を備える。複数の磁石保持リング2は、ねじ軸7の軸方向に連結される。複数の第1磁石3は、複数の磁石保持リング2のそれぞれに保持される。複数の第1磁石3は、各々が磁石保持リング2の円周方向に沿って配列される。複数の第2磁石4は、複数の磁石保持リング2のそれぞれに保持される。複数の第2永久4は、各々が第1磁石3同士の間に配置され、第1磁石3と磁極の配置を反転される。複数の導電リング5は、各々が導電性を有し、第1磁石3及び第2磁石4と隙間を空けて対向する。ボールナット6は、磁石保持リング2及び導電リング5の内部に配置されて磁石保持リング2に固定される。【選択図】図2 |
