Abstract:
(EN) Provided is a mechanism for converting rotary motion to linear motion capable of being configured to be compact and of obtaining a large reduction ratio. A mechanism for converting rotary motion into linear motion is configured so that rotational motion from a cylindrical member is transmitted to a shaft member via an engaging portion between the cylindrical member and each rod member and an engaging portion between each rod member and the shaft member and the shaft member moves linearly with respect to a housing. Internal teeth are provided on the inner circumferential face of the cylindrical member, and external teeth to engage with the internal teeth are provided on the outer circumferential face of each rod member. An annular support member comprising an outer circumferential face having a tooth portion to engage with the external teeth is provided. The annular support member is fixed to the housing.
(FR) L'invention concerne un mécanisme pour convertir un mouvement rotatif en un mouvement linéaire apte à être conçu pour être compact et obtenir un grand rapport de réduction. Un mécanisme pour convertir un mouvement rotatif en un mouvement linéaire est conçu de telle sorte que le mouvement de rotation d'un élément cylindrique est transmis à un élément d'arbre par l'intermédiaire d'une portion de mise en prise entre l'élément cylindrique et chaque élément de tige et une portion de mise en prise entre chaque élément de tige et l'élément d'arbre et l'élément d'arbre se déplace de façon linéaire par rapport à un boîtier. Des dents internes sont disposées sur la face circonférentielle intérieure de l'élément cylindrique, et des dents externes pour venir en prise avec les dents internes sont disposées sur la face circonférentielle extérieure de chaque élément de tige. Un élément support annulaire comprenant une face circonférentielle externe ayant une portion de dents pour venir en prise avec les dents externes est présent. L'élément support annulaire est fixé au boîtier.
(JA) コンパクトに構成しつつ、大きな減速比を得ることができる回転直動変換機構を提供する。 回転直動変換機構は、筒状部材からの回転運動が、筒状部材と各棒状部材との間の係合部と、各棒状部材と軸部材との間の係合部と、を経由して軸部材に伝達されて、軸部材がハウジングに対して直動するように構成される。筒状部材の内周面に、内歯が設けられ、各棒状部材の外周面に、内歯に噛み合う外歯が設けられる。外歯に噛み合う歯部を有する外周面を備える環状支持部材が備えられる。環状支持部材はハウジングに固定される。
