Abstract
本発明の固定式等速自在継手（３）は、外側継手部材（３１）と、内側継手部材（３２）と、８個のボール（３３）と、保持器（３４）とを備える。外側継手部材（３１）のトラック溝（３１ｄ）の曲率中心（Ｏ31d）と、内側継手部材（３２）のトラック溝（３２ｅ）の曲率中心（Ｏ32e）とは、それぞれ継手中心（Ｏ（ｆ））に対して軸方向反対側に等距離だけオフセットしている。また、ボール（３３）のピッチ円径（ＰＣＤBALL）とボール（３３）の直径（ＤBALL）との比（ＰＣＤBALL）／（ＤBALL）を３．７０～３．８７としている。更に、内側継手部材（３２）のトラック溝（３２ｅ）の軸方向長さ（ＷI・TRUCK）とボールの直径（ＤBALL）との比（ＷI・TRUCK／ＤBALL）を１．１～１．３としている。
