Abstract

L'invention concerne une turbine (1) pour turbomachine, notamment pour un turboréacteur ou un turbopropulseur d'avion, comportant un carter (2) et un rotor comprenant des aubes (29) dont la périphérie radialement externe comporte au moins une première léchette (31) s'étendant radialement vers l'extérieur, des moyens d'étanchéité s'étendant radialement autour des aubes (29) et comportant un anneau (14) en matériau abradable, les extrémités radialement externes des premières léchettes (31) étant engagée dans une gorge (17) dudit anneau (14) en matériau abradable de manière à former un joint de type labyrinthe, caractérisée en ce que ledit anneau (14) est formé de plusieurs secteurs angulaires (15) contigus, chaque secteur d'anneau (15) comportant au moins un organe de fixation (21, 25) coopérant avec au moins une bride d'accrochage complémentaire (4, 5) du carter (2) de manière à assurer le montage de chaque secteur (15) sur le carter (2) par déplacement axial dudit secteur (15) par rapport au carter (2).
