Title
(EN) MOTOR-DRIVEN CYLINDER
(FR) CYLINDRE ACTIONNE PAR MOTEUR
Abstract
(EN)
A motor-driven cylinder with a novel configuration that can be used even at a narrow space where a conventional cylinder cannot be mounted and that has a length shorter than a conventional one which has the same stroke. The cylinder comprises a motor (1), a ball nut (4) linked to the motor (1) via a transmission member (3) and rotatable on the thrust bearing (5) mounted to the outer diameter portion, and a ball screw (6) screwed into the ball nut (4), with one end projecting outside the cylinder case (2).
(FR)
Cylindre actionné par moteur à configuration originale, pouvant être utilisé même dans un espace restreint où un cylindre conventionnel ne peut pas être installé, et dont la longueur est inférieure à celle d'un cylindre conventionnel possédant la même course. Le cylindre comprend un moteur (1), un écrou à billes (4) relié au moteur au moyen d'un membre de transmission (3) et pouvant tourner autour de son axe grâce à un palier de butée (5) monté sur une partie du diamètre extérieur, ainsi qu'une vis à bille (6) vissée dans l'écrou à billes (4) et dont l'une des extrémités dépasse du boîtier (2) du cylindre.
