Abstract

L'invention concerne un système (26) de changement de pas de pales d'au moins une hélice de turbomachine munie d'une pluralité de pales, comprenant : - un mécanisme de liaison (31) relié aux pales de l'hélice au niveau d'une première interface (32), - un moyen de commande (27) agissant sur ledit mécanisme de liaison et comportant un corps mobile (29) en translation selon un axe longitudinal (X), et - un module (51) de transfert de charge, agencé entre le mécanisme de liaison et le moyen de commande, et relié au niveau d'une deuxième interface (38) au mécanisme de liaison. Le système comprend des moyens de réglage (43) du calage des pales comportant des premiers éléments de réglage (44) configurés de manière à ajuster une position axiale de la deuxième interface (38) suivant l'axe (X), et des seconds éléments de réglage (37, 47) configurés de manière à ajuster une distance axiale suivant l'axe (X) entre la première interface (32) et la deuxième interface (38).
