(FR) DISPOSITIF DE TRANSMISSION D'ÉNERGIE
(JA) 動力伝達装置
Abstract:
(EN) Provided is a technique contributing to increasing the efficiency of power transmission and reducing the size of a device, without being affected by an environment under which a load is installed. A power transmission device has: an axial gap type rotating electric machine having a stator and a rotor, said stator having coils on the radial direction outer perimeter side of teeth that extend in a rotational axis direction and generating a magnetic flux from end surfaces of the teeth in the rotational axis direction, said rotor having a plurality of magnets that have different polarities and are disposed in a ring shape, and having a surface facing the end surfaces of the teeth with a predetermined gap interposed therebetween; a housing having a space for storing the stator and the rotor; a partition wall for dividing the region storing the stator and the rotor in the housing into discontinuous spaces; a bearing disposed on the partition wall and rotatably supporting the rotor; and a load device disposed on the rotor on the opposite side to the stator in the axial direction and rotating together with the rotor.
(FR) L'invention concerne une technique contribuant à augmenter le rendement de transmission d'énergie et à réduire la taille d'un dispositif, sans subir l'influence de l'environnement dans lequel une charge est installée. L'invention porte sur un dispositif de transmission d'énergie comprenant : une machine électrique tournante du type à entrefer axial comprenant un stator et un rotor, ledit stator comportant des bobines sur le côté du périmètre radialement extérieur de dents qui s'étendent dans la direction d'un axe de rotation et générant un flux magnétique à partir de surfaces d'extrémité des dents dans la direction de l'axe de rotation, ledit rotor comportant une pluralité d'aimants qui ont différentes polarités et sont disposés en forme d'anneau, et présentant une surface en regard des surfaces d'extrémité des dents avec un entrefer prédéterminé intercalé entre elles; un boîtier comportant un espace pour stocker le stator et le rotor; une paroi de séparation pour diviser en espaces discontinus la région stockant le stator et le rotor dans le boîtier; un palier disposé sur la paroi de séparation et supportant le rotor en rotation; et un dispositif de charge disposé sur le rotor du côté opposé au stator dans la direction axiale et tournant avec le rotor.
(JA) 負荷が設置される環境に影響されず、動力伝達の効率化及び装置の小型化に資する技術を提供する。動力伝達装置は、回転軸方向に延伸するティースの径方向外周側にコイルを有し、ティース端面から回転軸方向に磁束を発生するステータと、磁極の異なる複数の磁石を環状に配置し、前記ティース端面と所定のギャップを介して面対向するロータとを有するアキシャルギャップ型回転電機と、前記ステータ及び前記ロータを格納する空間を有する筺体と、前記筺体内で前記ステータとロータの格納領域を不連続空間として区画する隔壁と、前記隔壁に配置され、前記ロータを回転可能に支持する軸受と、前記ロータの前記ステータと軸方向反対側に配置されて前記ロータと共回りする負荷装置とを有する。
