Abstract

Support permettant de réduire le jeu entre le rotor et l'anneau de protection d'une turbomachine au cours du fonctionnement à des régimes variables. Il comprend un arbre 32 raccordant un secteur d'anneau de protection 12 à la structure de support 23, cet arbre étant monté à rotation dans la structure de support sur un axe parallèle à l'axe du rotor et comportant une surface excentrique qui s'appuie et frotte contre le secteur d'anneau de protection qu'elle porte ; et des moyens 51, 52, 53 pour entraîner l'arbre en rotation en réponse à des paramètres de fonctionnement prédéterminés du moteur pour moduler sélectivement la position radiale du secteur d'anneau de protection. Application aux moteurs d'avion.
