- トルクを受けて回転する回転体に、複数のガイド孔が前記回転体の円周方向に所定の間隔をあけて形成され、複数の前記ガイド孔のそれぞれに転動体が収容されるとともに、各々の前記転動体が連結部材によって連結されており、前記回転体が回転することによる遠心力によって前記転動体が前記ガイド孔の内面のうち前記回転体の半径方向で外側の内面であるガイド面に押し付けられるとともに前記トルクが変動することによる慣性力によって前記転動体が前記回転体の円周方向に往復動するように構成されている捩り振動低減装置において、
前記連結部材は、環状の支持部と、前記支持部の円周方向で前記ガイド孔に対応する位置に設けられかつ前記回転体の半径方向で前記転動体の外周面側から前記転動体を保持する収容部とを備えていて前記転動体と共に往復動するように構成され、
前記収容部は、前記転動体が往復動する場合における前記回転体の軸線方向での前記転動体の重心の予め決まっている移動長さより幅広に形成されていて前記転動体の外周面のうち前記移動長さを含む範囲を前記外周面側から保持しかつ前記ガイド孔内に配置されており、
前記外周面に前記転動体の往復動方向で接触する少なくとも2つの接触部が前記収容部の内面に形成されている
ことを特徴とする捩り振動低減装置。
- 2つの前記接触部は、前記外周面に前記転動体の往復動方向で線接触または点接触するように前記収容部の内面に形成されている
ことを特徴とする請求項1に記載の捩り振動低減装置。 - 2つの前記接触部は、前記回転体の半径方向で前記転動体の重心より外側の前記外周面であってかつ前記回転体の円周方向で前記重心を挟んで両側の前記外周面に線接触または点接触するように形成されている
ことを特徴とする請求項1に記載の捩り振動低減装置。
