Abstract

Dispositif d'équilibrage (4) pour arbre supercritique de turbomachine, en particulier pour un arbre basse pression supercritique, caractérisé en ce qu'il est de forme allongée et comprend deux parties longitudinales adjacentes (5, 6), dont une première partie (5) de support et de positionnement, dite partie support, et une deuxième partie (6) de balourd de correction, dite partie balourd, la partie support (5) présentant une surface extérieure destinée à venir en contact avec une surface intérieure de l'arbre, et la partie balourd (6) comprenant au moins deux réservoirs de masse (9) s'étendant longitudinalement depuis un pourtour transversal extérieur de la partie support (5), de manière à ce que chaque réservoir (9) vienne en contact avec la surface intérieure de l'arbre sous l'effet de la force centrifuge lorsque l'arbre est en rotation.
