Abstract

L'invention concerne un dispositif de commande d'aube à angle de calage variable pour compresseur de turbomachine, comportant un pivot (10) d'une aube à commander, une biellette (16), des moyens de fixation d'une première extrémité de la biellette sur ledit pivot (10), et des moyens de liaison (20, 22) entre une seconde extrémité (16b) de la biellette et un anneau de commande (18). Le pivot (10) se termine par une tête (14) sensiblement cylindrique sur laquelle est engagée de façon perpendiculaire la première extrémité de la biellette, cette première extrémité étant munie de moyens de pincement de la tête du pivot selon une direction (Z-Z) sensiblement perpendiculaire à la fois à un axe longitudinal (X-X) de la biellette (16) et à un axe principal (Y-Y) du pivot (10) de l'aube.
