Abstract

La présente invention concerne un rotor (1) de turbine, notamment d’une turbine basse pression, d'une turbomachine, qui comprend au moins un disque de rotor amont (2) et un disque de rotor aval (3), chacun étant configuré pour supporter à sa périphérie les pieds des aubes radiales dudit rotor. Conformément à l'invention, ce rotor comprend au moins un anneau d’étanchéité (4), muni à sa périphérie extérieure d'au moins une léchette annulaire d'étanchéité (44), les deux disques de rotor et l'anneau d'étanchéité sont des éléments distincts, le disque amont (2) et/ou le disque aval (3) comprend une bride annulaire de vissage (23, 34), dont une face cylindrique axiale (24, 35) est munie d'un filetage (240, 350) circonférentiel, l’anneau d’étanchéité (4) comprend à au moins l'une de ses deux extrémités axiales (41, 42), un filetage (450, 480) circonférentiel complémentaire du filetage (240, 350) de la bride annulaire de vissage (23, 34) et qui coopère avec celui-ci pour assurer la fixation de l’anneau (4) sur ledit disque de rotor amont (2) et/ou aval (3) par vissage.
