Description
また、ジョイント作動角を所定の角度として、内輪の外径を小さくするように設計変更した場合には、トルク伝達時、すなわちボール型等速ジョイントの使用状態におけるボールの動作範囲は短くなる。このことは、ある点を中心とした円弧長は、半径が大きいほど長くなり、半径が小さいほど短くなる関係から明らかである。一方、内輪の内周面には、シャフトの外周面とトルク伝達を可能とするために、例えばスプラインが形成されている。必要なトルクを伝達するためには、当該スプラインの軸方向長さは設計上決定される。つまり、内輪の軸方向長さは、スプラインの軸方向長さから決定される。従って、内輪の外径の小型化を図ることによりボールの動作範囲が狭くなるのに対して、必要な内輪の軸方向長さは変わらないため、内輪ボール溝において内輪ボール溝とボールとの接点軌跡を確保しなくてもよい部分が存在することになる。そこで、この部分を利用して、本発明は、軸方向他方側において切欠を形成することにしている。
つまり、本発明は、軸方向他方側の切欠が形成される軸方向位置は、内輪ボール溝とボールとの接点軌跡が設定されないようにしている。これにより、軸方向他方側の切欠の径方向深さを十分に深くすることができる。従って、内輪および保持器を小型化したとしても、内輪と保持器の組み付けが可能となる。
