Abstract
Description
(1)外輪と、内輪と、前記外輪及び内輪の間に配置される複数の転動体と、前記複数の転動体を円周方向に所定の間隔を持って保持する複数のポケットを有する外輪案内方式の保持器と、を備える転がり軸受であって、
前記保持器の外周面には軸方向に延びる溝が形成されており、
前記保持器の中心位置の変位量をxo、前記保持器の外径をDoc、前記外輪の案内径をDog、前記溝の周方向幅をh、前記外輪と前記保持器との案内隙間をΔLo、前記ポケットと前記転動体との間の隙間をΔP、としたとき、
(2)外輪と、内輪と、前記外輪及び内輪の間に配置される複数の転動体と、前記複数の転動体を円周方向に所定の間隔を持って保持する複数のポケットを有する内輪案内方式の保持器と、を備える転がり軸受であって、
前記保持器の内周面には軸方向に延びる溝が形成されており、
前記保持器の中心位置の変位量をxi、前記保持器の内径をDic、前記内輪の案内径をDig、前記溝の周方向幅をh、前記内輪と前記保持器との案内隙間をΔLi、前記ポケットと前記転動体との間の隙間をΔP、としたとき、
まず、第1実施形態に係る転がり軸受について、図1~5を用いて説明する。図1に示されるように、第1実施形態に係るアンギュラ玉軸受1は、内周面に外輪軌道面2aを有する外輪2と、外周面に内輪軌道面3aを有する内輪3と、外輪2の外輪軌道面2a及び内輪3の内輪軌道面3aの間に配置される複数の玉4と、複数の玉4を円周方向に所定の間隔を持って保持する保持器10と、を備える。
次に、本発明の第2実施形態に係る転がり軸受を、図6~9に基づいて説明する。図6は、第2実施形態に係るアンギュラ玉軸受1´の断面の要部拡大図である。尚、第2実施形態のアンギュラ玉軸受1´は、保持器が内輪案内方式である他は、第1実施形態のアンギュラ玉軸受1と同様であるので、同一部分には同一符号又は相当符号を付して説明を簡略化又は省略する。
