Abstract

L'invention concerne une enceinte lubrifiée (20) de turbomachine d'aéronef, dans laquelle est agencée un palier de roulement inter-turbine (22), l'enceinte étant formée par : - un tourillon (26) solidaire en rotation d'un arbre de turbine basse pression (14), - un tourillon (70) solidaire en rotation d'un rotor de turbine haute pression (12) ; - un joint d'étanchéité à labyrinthe (84) comprenant une partie (82) portée par le tourillon (70), ainsi qu'une partie complémentaire (86) solidaire en rotation du tourillon (26), l'enceinte présentant un espace intérieur (24) logeant une bague support de roulement (72) présentant une extrémité aval fixée sur le tourillon (26), et portant une piste annulaire externe (74) du palier (22), une piste interne (78) étant portée par le tourillon (70). Selon l'invention la partie (86) du joint à labyrinthe est solidaire d'une extrémité amont (72b) de la bague (72).The invention relates to a lubricated enclosure (20) for an aircraft turbomachine, in which an inter-turbine rolling bearing (22) is arranged, the enclosure being formed by: - a journal (26) integral in rotation with a low pressure turbine shaft (14), - a journal (70) integral in rotation with a high pressure turbine rotor (12); - a labyrinth seal (84) comprising a part (82) carried by the journal (70), as well as a complementary part (86) integral in rotation with the journal (26), the enclosure having an interior space (24) housing a bearing support ring (72) having a downstream end fixed to the journal (26), and carrying an outer annular track (74) of the bearing (22), an internal track (78) being carried by the journal (70). According to the invention the part (86) of the labyrinth seal is integral with an upstream end (72b) of the ring (72).
