Description
支持部材5に支持されたカム回転軸1Aと、このカム回転軸1Aに取り付けられこの回転軸を中心に回転するC字状の立体カム1と、前記支持部材5に前記カム回転軸1Aから離れた位置で支持された従節関節回転軸4Aと、前記従節関節回転軸4Aに取り付けられ同軸を中心に回転する従節側リンク4とを備え、前記立体カム1には、独立した一対の3次元的な立体カム案内面2、3が径方向に所定間隔をおいて共にC字状に形成され、また前記従節側リンク4の一端側には所定の角度をもって配置された一対のカムフォロワ6、7に軸支されたガイドローラ8、9が設けられ、前記立体カム1に形成された一対の3次元的な立体カム案内面2、3に前記従節側リンク4に設けた一対のカムフォロワ6、7のガイドローラ8、9を当接して、前記立体カム1の回転により立体カム案内面2、3のガイドローラ8、9が当接する箇所のカム回転軸1Aからの半径とカム回転軸1A方向の高さが徐々に変化するように設けることで、前記立体カム1の回転運動を従節側リンク4の他端の揺動運動に変換するように構成したことを特徴とする立体カム機構である。
また、前記従節側リンク4側からの揺動運動を立体カム1側の回転運動にも変換可能に構成したことを特徴とする立体カム機構である。
また、前記前記従節側リンク4におけるカムフォロワ6、7またはガイドローラ8、9を前記立体カム1のカム案内面2、3に押し付ける付勢手段を前記カムフォロワ6、7または従節側リンク4に設置したことを特徴とする。
また、前記支持部材5を上下に分割構成とするとともに、これら上下支持部材間を相対回転自在に構成したことを特徴とする立体カム機構である。
