Abstract
Système de commande de deux étages (10, 10') d'aubes de stator (14, 14') à angle de calage variable de turbomachine, comportant un élément de manoeuvre (24) pour entraîner en rotation l'anneau de commande (22) de l'un des étages (10) par l'intermédiaire d'un organe pilote (26) monté de façon pivotante sur le carter (12), une barre de synchronisation (30) pour transmettre le mouvement de rotation de l'anneau entraîné (22) par l'élément de manoeuvre (24) à l'anneau de commande (22') de l'autre étage (10') par l'intermédiaire d'un organe suiveur (26') monté de façon pivotante sur le carter, et un organe pivotant supplémentaire (44) intercalé entre l'organe suiveur (26') et l'anneau suiveur (22'), ledit organe pivotant supplémentaire (44) étant monté de façon pivotante à la fois sur le carter (12) et sur l'organe suiveur (26'). A two-stage control system (10, 10 ') of stator vanes (14, 14') with a variable turbine engine pitch angle, comprising an operating element (24) for rotating the control ring (22) ) of one of the stages (10) via a pilot member (26) pivotally mounted on the housing (12), a synchronizing bar (30) for transmitting the rotational movement of the ring driven (22) by the operating element (24) to the control ring (22 ') of the other stage (10') via a follower member (26 ') pivotally mounted on the housing, and an additional pivoting member (44) interposed between the follower member (26 ') and the follower ring (22'), said additional pivot member (44) being pivotally mounted to both the housing ( 12) and on the follower member (26 ').
