Abstract

　本発明は、簡易な装置により、環境への悪影響が少なく、また、高い生産性でトラニオンジャーナルを高精度に加工できる加工方法と、その加工方法によって形成されたトラニオンと、そのトラニオンを用いたトリポード型等速自在継手を提供する。外側継手部材１は、内周面に軸方向に延びる３つのトラック溝１１を有し、トラニオン２は、ボス軸２１の円周方向三等分位置から半径方向に突出した柱状のトラニオンジャーナル２２を有する。トラニオンジャーナル２２を、縦断面においてはストレート形状とし、横断面においては、継手円周方向に長軸を有する楕円形状とする。このトラニオンジャーナル２２は、焼入鋼のドライ切削によって形成する。トラニオンジャーナル２２の回りに回転自在に嵌合するローラカセット３は、ローラ３１と、インナーリング３２と、ローラ３１とインナーリング３２との間に挟持された複数の針状ころ３３を有する。
