The invention concerns a centering adjustment device of a synchronizing ring for controlling the pivoting blades of a turbine engine, including a control ring (26) centered on a longitudinal axis (X-X) of the turbine engine and equipped with a plurality of threaded holes (36) extending in a radial direction, and a plurality of pad-holders (32) each including a threaded rod (34) screwed into one of the threaded holes (36) of the ring, each pad-holder (32) having a pad (30) at an inner end intended to come into contact with a cylindrical envelope (28) coaxial to the ring. The control ring (26) also includes a plurality of slits (38) extending in a tangential direction, each slit (38) in communication with one of the threaded holes (36) of the ring. The device includes the means (40, 42a, 42b) to pinch each of the slits (38) in a longitudinal direction to ensure the pad-holders (32) are locked in place.
L'invention concerne un dispositif de réglage du centrage d'un anneau de commande d'aubes pivotantes de turbomachine, comportant un anneau de commande (26) centré sur un axe longitudinal (X-X) de la turbomachine et muni d'une pluralité de trous taraudés (36) s'étendant selon une direction radiale, et une pluralité de porte-patins (32) comportant chacun une tige filetée (34) vissée dans l'un des trous taraudés (36) de l'anneau, chaque porte-patin (32) portant à une extrémité interne un patin (30) destiné à venir en contact d'une enveloppe cylindrique (28) coaxiale à l'anneau. L'anneau de commande (26) comporte en outre une pluralité de fentes (38) s'étendant selon une direction tangentielle, chaque fente (38) communiquant avec l'un des trous taraudés (36) de l'anneau. Le dispositif comporte des moyens (40, 42a, 42b) de pincement selon une direction longitudinale de chacune des fentes (38) de façon assurer un blocage en position des porte-patins (32).
