CA 2476903

The invention relates to a linear, hydraulic pivot drive, especially for the flap control system of aerodynamic structures. Said pivot drive comprises a housing provided with ports for introducing a hydraulic medium, a piston which is arranged inside the housing and can be axially displaced by the effect of the hydraulic medium, and an output shaft which is provided with coarse threads and interacts with the piston in order to cover the axial displacement of the piston into a rotational movement. The invention is characterized in that the output shaft is integrated into the piston, the coarse threads running in the same direction and engaging in the piston, and the cross-section of the piston has a spline profile for effectively preventing a rotational movement of the piston.

La présente invention concerne un dispositif d'entraînement en rotation hydraulique linéaire destiné notamment à entraîner les volets de structures aérodynamiques. Le dispositif d'entraînement en rotation (1) comprend un boîtier (2) doté d'éléments de raccord (3, 4) destinés à l'introduction d'un fluide hydraulique, un piston (5) qui est disposé dans le boîtier (2) et peut se déplacer en direction axiale sous l'action du fluide hydraulique, ainsi qu'un arbre de sortie (6) présentant des filets à pas rapide (8a, 8b), ledit arbre de sortie coopérant avec le piston (5) pour convertir le mouvement axial du piston (5) en un mouvement de rotation. L'invention se caractérise en ce que l'arbre de sortie (6) est mis en place dans le piston (5), les filets à pas rapide (8a, 8b) étant pratiqués dans le même sens et s'encliquetant dans le piston (5), et en ce que la section du piston a un profil polygonal qui empêche efficacement le mouvement de rotation du piston (5).
