Description
実施例では、外歯歯車が内歯歯車と噛み合いながら偏心回転するタイプの歯車伝動装置について説明する。本明細書が開示する技術は、他のタイプの歯車伝動装置、例えば、内歯歯車が外歯歯車と噛み合いながら偏心回転するタイプの歯車伝動装置に適用することもできる。
図7,8を参照し、第2実施例の歯車伝動装置について説明する。本実施例の歯車伝動装置は、リテーナの形状が歯車伝動装置100と異なるだけである。具体的には、本実施例のリテーナ144は、ケース接触面に形成されている外周溝とキャリア接触面に形成されている端面溝との位置関係がリテーナ44と異なる。リテーナ144とリテーナ44で共通する特徴は、同一又は下二桁が同じ番号を付すことにより、説明を省略することがある。
図9,10を参照し、第3実施例の歯車伝動装置について説明する。本実施例の歯車伝動装置は、リテーナの形状が歯車伝動装置100と異なるだけである。具体的には、本実施例のリテーナ244は、ケース接触面に形成されている外周溝の形状とキャリア接触面に形成されている端面溝の形状とがリテーナ44と異なる。リテーナ244とリテーナ44で共通する特徴は、同一又は下二桁が同じ番号を付すことにより、説明を省略することがある。
図11を参照し、歯車伝動装置300について説明する。歯車伝動装置300は歯車伝動装置100の変形例であり、歯車伝動装置100と同じ部品には、同一又は下二桁が同じ番号を付すことにより説明を省略することがある。
