DRIVE DEVICE
(FR)
DISPOSITIF D'ENTRAÎNEMENT
(JA)
駆動装置
Abstract:
(EN)
A drive device comprises a rotor having a helical projection part, a stator having a helical groove part, and an output part for driving by movement of the rotor, and has a configuration in which the helical rotor and stator are combined together. The rotor is composed of one or more rotor units having a length in the axial direction of the rotor that is less than the length of a circulation track, the rotor unit allows movement of the rotor on the circulation track by the advancement action of the rotor unit in the axial direction during helical movement with respect to the rotor, the helical portions of the rotor and the stator are caused to face each other, and the torque density of the drive torque is increased by using the magnetic force therebetween.
(FR)
L'invention concerne un dispositif d'entraînement qui comprend un rotor ayant une partie projection hélicoïdale, un stator ayant une partie rainure hélicoïdale et une partie de sortie destinée à être entraînée par le mouvement du rotor, et présente une configuration dans laquelle le rotor et le stator hélicoïdaux sont combinés ensemble. Le rotor est composé d'une ou plusieurs unités de rotor ayant une longueur dans la direction axiale du rotor qui est inférieure à la longueur d'un chemin de circulation, l'unité de rotor permettant le déplacement du rotor sur le chemin de circulation sous l'effet de l'action d'avancement de l'unité de rotor dans la direction axiale pendant le mouvement hélicoïdal par rapport au rotor, les parties hélicoïdales du rotor et du stator étant amenées à se faire face et la densité de couple du couple d'entraînement étant accrue à l'aide de la force magnétique qui s'exerce entre ces derniers.
(JA)
駆動装置は、らせん状の突起部を有する回転子と、らせん状の溝部を有する固定子と、回転子の移動によって駆動する出力部とを備え、らせん状の回転子と固定子との組み合わせた構成であり、回転子軸方向の長さを循環軌道の長さよりも短い一つ又は複数の回転子ユニットで回転子を構成し、回転子ユニットが固定子に対するらせん運動において、回転子ユニットの軸方向の進行動作によって回転子を循環軌道上での移動を可能とし、回転子と固定子とのらせん状部分を対向させ、この間の磁力を用いることで駆動トルクのトルク密度を高める。
