Abstract

Ensemble rotatif pour turbomachine, notamment turbine de turbomoteur d'hélicoptère, comprenant un rotor comportant au moins une roue aubagée (11), un anneau de stator (21), entourant la roue aubagée (11) et définissant au moins partiellement une veine pour un fluide de travail, un carter externe (25) entourant concentriquement l'anneau de stator (21), et un dispositif de calage (30) comportant au moins une cale (31) prévue entre l'anneau de stator (21) et le carter externe (25) pour restreindre la déformation de l'anneau de stator (21) lors du fonctionnement de l'ensemble rotatif (7).
