- 球状内周面に軸方向に延びる複数のトラック溝が形成され、軸方向に離間する開口側と奥側を有する外側継手部材と、球状外周面に前記外側継手部材のトラック溝と対をなす複数のトラック溝が形成された内側継手部材と、前記外側継手部材のトラック溝と前記内側継手部材のトラック溝との間に介在してトルクを伝達する複数のボールと、ボールを保持し、前記外側継手部材の球状内周面および前記内側継手部材の球状外周面にそれぞれ嵌合する球状外周面および球状内周面を有する保持器とを備えた固定式等速自在継手において、
前記外側継手部材のトラック溝は、奥側に位置する第1トラック溝部と開口側に位置する第2トラック溝部とからなり、前記第1トラック溝部は、継手中心に対して開口側にオフセットした位置に曲率中心をもつ円弧状のボール軌道中心線を有し、少なくともこのボール軌道中心線と継手中心を含む平面が継手の軸線に対して周方向に傾斜すると共にその傾斜方向が周方向に隣り合う前記第1トラック溝部で互いに反対方向に形成されており、前記第2トラック溝部のボール軌道中心線は、最大作動角に対する有効トラック長さを増加させるために直線状部分を有し、かつ継手中心よりも開口側で前記第1トラック溝部のボール軌道中心線と接続されており、
前記内側継手部材のトラック溝のボール軌道中心線は、作動角0°の状態の継手中心平面を基準として、前記外側継手部材の対となるトラック溝のボール軌道中心線と鏡像対称に形成されていることを特徴とする固定式等速自在継手。 - 前記第1トラック溝部と前記第2トラック溝部のボール軌道中心線の接続点と継手中心とを結ぶ直線が、作動角0°の状態の継手中心平面に対してなす角度βを3°〜10°に設定した請求項1に記載の固定式等速自在継手。
- 前記第1トラック溝部のボール軌道中心線の曲率中心を、継手の軸線に対して周方向に傾斜した傾斜軸上に配置した請求項1又は2に記載の固定式等速自在継手。
- 前記第1トラック溝部のボール軌道中心線の曲率中心を、継手の軸線に対して周方向に傾斜した傾斜軸に対し、半径方向にオフセットした位置に配置した請求項1又は2に記載の固定式等速自在継手。
- 前記保持器の球状外周面および球状内周面の曲率中心を、継手中心に対して奥側および開口側にそれぞれオフセットした位置に配置した請求項1〜4の何れか一項に記載の固定式等速自在継手。
- 前記第2トラック溝部のボール軌道中心線は、その全域が直線状部分で構成され、前記第1トラック溝部のボール軌道中心線の接線として形成されている請求項1〜5の何れか一項に記載の固定式等速自在継手。
- 前記第2トラック溝部のボール軌道中心線は、前記第1トラック溝部のボール軌道中心線の曲率半径とは異なる曲率半径の円弧状部分を含んでおり、この円弧状部分が、前記第1トラック溝部のボール軌道中心線に接続されている請求項1〜5の何れか一項に記載の固定式等速自在継手。
- 前記第2トラック溝部のボール軌道中心線の直線状部分が、継手の軸線と平行に形成されている請求項1〜5の何れか一項に記載の固定式等速自在継手。
- 前記第2トラック溝部のボール軌道中心線を継手の軸線に対して周方向に傾斜させ、かつその傾斜角を、開口側に向けて徐々に減少させた請求項1〜8の何れか一項に記載の固定式等速自在継手。
- 前記ボールの個数を8個、10個又は12個の何れかとした請求項1〜9の何れか一項に記載の固定式等速自在継手。
