Abstract

Turbine pour turbomachine d’axe longitudinal (X1), la turbine comprenant un carter externe (20) annulaire entourant un anneau (30), l’anneau (30) comprenant une plateforme annulaire (31) et une bride annulaire aval (33) s’étendant radialement vers l’extérieur depuis la plateforme annulaire (31) et par laquelle l’anneau (30) est fixé au carter externe (20), la bride annulaire aval (33) présentant une face aval qui est appliquée, dans la direction longitudinale (X), contre une paroi annulaire radiale (22) du carter externe (20), la turbine comprenant en outre des moyens aval de rattrapage de jeu intercalés longitudinalement entre la face aval de la bride annulaire aval (33) de l’anneau (30) et la paroi annulaire radiale (22) du carter externe (20). Figure de l’abrégé : Figure 3Turbine for a longitudinal axis turbomachine (X1), the turbine comprising an annular external casing (20) surrounding a ring (30), the ring (30) comprising an annular platform (31) and a downstream annular flange (33) s extending radially outwards from the annular platform (31) and by which the ring (30) is fixed to the outer casing (20), the downstream annular flange (33) having a downstream face which is applied, in the direction longitudinal (X), against a radial annular wall (22) of the external casing (20), the turbine further comprising downstream means for taking up play interposed longitudinally between the downstream face of the downstream annular flange (33) of the ring (30) and the radial annular wall (22) of the outer casing (20).
