Description
本発明は、前述した従来の振動減衰装置と同様に、コイルばねと粘弾性シートとを含む点では共通するが、その構成は極めてシンプルである。したがって、振動対策用の機械部品として各種機器に組み込んで使用されるコイルばねと同様に、機械部品としての取扱いが可能である。よって、従来ではコイルばね以外にダンパーを別体として他の場所に併設せざるを得なかった振動対策を、本発明であれば、ダンパーの併設が不要で、ダンピングコイルばね単体で実現することができる。

Claims (4)
- 振動を受けて伸縮変形するコイルばねと、
コイルばねの外周に圧着した粘弾性シートとを備えるダンピングコイルばねにおいて、
前記粘弾性シートは、
各コイルの素線の縦断面輪郭における前記外周側の円弧形状に沿って隙間無く固着することでコイルばねのすべての素線を常時直接拘束する圧着部分と、
隣接するコイルの素線間の隙間内でコイルばねの中心軸に向けて湾曲しつつ隣接する前記圧着部分どうしを繋ぐ湾曲部とを有しており、
振動によりコイルばねが伸縮変形すると、コイルばねのすべての素線が前記圧着部分によって常時直接拘束された状態で前記湾曲部が隣接する素線どうしの変位と連動しつつコイルばねの中心軸に向けて内向きに折れ曲がり変形することで粘性抵抗を発揮して、コイルばねの伸縮変形を減衰させるものである、ことを特徴とするダンピングコイルばね。 - 一方面をコイルばねに圧着した粘弾性シートの他方面に、粘弾性シートの保護シートを周着した請求項1記載のダンピングコイルばね。
- コイルばねが、圧縮コイルばね、引っ張りコイルばね、ねじりコイルばねの何れかである請求項1又は請求項2記載のダンピングコイルばね。
- 請求項1〜請求項3何れか1項記載のダンピングコイルばねを備える振動減衰装置。
