Abstract

Dispositif de centrage sans frettage pour le centrage de pièces rotor Dispositif de centrage (1) pour une pièce rotor interne (2) et une pièce rotor externe (3) concentriques et centrées autour d’un axe (X-X’), fixées l’une à l’autre. Il comprend au moins trois taquets mobiles (5) montés chacun coulissant dans un logement (6) selon un axe orthogonal à l’axe (X-X’), chaque logement (6) étant situé sur une face radiale externe (7) de la pièce rotor interne (2), chaque logement (6) présentant un fond (8) et des parois internes (9) et lesdits logements (6) étant répartis radialement autour de l’axe (X-X’), chaque taquet mobile (5) étant situé au voisinage immédiat des parois internes (9) du logement (6) dans lequel il coulisse et chaque taquet mobile (5) présentant une longueur (L) supérieure à la distance d’écartement (E) qui le sépare de la pièce rotor externe (3) lorsqu’il est au fond (8) de son logement (6).
