Abstract

Dispositif de réglage du centrage d'un anneau de commande (26) d'aubes pivotantes de turbomachine, comportant une pluralité de patins (30) destinés à venir en contact d'une surface circulaire (28) coaxiale à l'anneau (26), chaque aube pivotante étant reliée à l'anneau de commande (26) au moyen d'une biellette (20) ayant une première extrémité fixée à l'anneau de commande par un tourillon (24) disposé radialement sur ledit anneau et une deuxième extrémité montée sur un pivot de l'aube, les patins (30) étant solidaires chacun d'un porte-patin (32). Chaque porte-patin (32) est fixé sous l'anneau de commande (26) au moyen de systèmes d'attache (38) qui sont destinés à être assemblés par le dessus de l'anneau.

Figure imgaf001
Device for adjusting the centering of a control ring (26) of turbomachine pivoting vanes, comprising a plurality of pads (30) intended to come into contact with a circular surface (28) coaxial with the ring (26) each swivel blade being connected to the control ring (26) by means of a link (20) having a first end attached to the control ring by a journal (24) radially disposed on said ring and a second end mounted on a pivot of the blade, the pads (30) being each secured to a shoe holder (32). Each shoe carrier (32) is secured under the control ring (26) by means of fastening systems (38) which are to be assembled from above the ring.
