EDDY CURRENT DAMPER
To provide an eddy current damper capable of suppressing excessive temperature rise of a conductive member and a permanent magnet.SOLUTION: An eddy current damper 1 comprises a screw shaft 2, a ball nut 3, a magnet holding member 4, a ventilation flue 5, a first permanent magnet 6, a second permanent magnet 7, and a conductive member 8. The cylindrical magnet holding member 4 is fixed to the ball nut 3. The ventilation flue 5 is provided in the magnet holding member 4, and inclined to an axis direction C of the magnet holding member 4. The first permanent magnet 6 is adjacent to the ventilation flue 5 in a circumferential direction of the magnet holding member 4, and fixed to the magnet holding member 4. The second permanent magnet 7 is adjacent to the first permanent magnet 6 with the ventilation flue 5 held therebetween in a circumferential direction of the magnet holding member 4, and is fixed to the magnet holding member 4, and a magnetic pole thereof is arranged inversely to that of the first permanent magnet 6. The cylindrical conductive member 8 has conductivity, and is opposite to the first permanent magnet 6 and the second permanent magnet 7 at intervals.SELECTED DRAWING: Figure 3
【課題】導電部材及び永久磁石の過度な温度上昇を抑制でき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２と、ボールナット３と、磁石保持部材４と、通風路５と、第１永久磁石６と、第２永久磁石７と、導電部材８と、を備える。円筒形状の磁石保持部材４は、ボールナット３に固定される。通風路５は、磁石保持部材４に設けられ、磁石保持部材４の軸方向Ｃに対し傾斜する。第１永久磁石６は、磁石保持部材４の円周方向において通風路５に隣接し、磁石保持部材４に固定される。第２永久磁石７は、磁石保持部材４の円周方向において通風路５を挟んで第１永久磁石６に隣接し、磁石保持部材４に固定され、第１永久磁石６と磁極の配置が反転している。円筒形状の導電部材８は、導電性を有し、第１永久磁石６及び第２永久磁石７と隙間を空けて対向する。【選択図】図３
