Abstract
【解決手段】 円筒状内周面12に軸方向に延びる複数のトラック溝14を形成した外輪10と、球面状外周面22に軸方向に延びる複数のトラック溝24を形成した内輪20と、外輪10のトラック溝14と内輪20のトラック溝24との対で形成されるボールトラックに一個ずつ組み込んだ6個のトルク伝達ボール30と、そのトルク伝達ボール30を保持するポケット46を有するケージ40とを備え、そのケージ40の球面状外周面42の中心Ooと球面状内周面44の中心Oiを、継手中心Oを挟んで軸方向に互いに逆方向に等距離だけオフセットさせた等速自在継手において、ボールトラックの円周方向配置を等ピッチにすると共に、ケージ40のポケット46の円周方向配置を55°以上のランダムな不等ピッチとする。
【選択図】 図1
Description
この発明では、外輪の内周面とケージ外周面との接触部の面粗さを少なくとも一箇所以上で不均一にすることにより、前項(3)で述べたように外輪の内周面とケージ外周面との接触部の幅を少なくとも一箇所以上で不均一にした場合と同様、各位相に発生する摩擦力の変動成分も不均一になることから、誘起スラスト力のn次成分を低減できる。
