Title (EN) TRUNNION FOR HIGH-PRESSURE TURBINE, AND TURBOJET ENGINE INCLUDING SUCH A TRUNNION
(FR) TOURILLON POUR TURBINE HAUTE PRESSION, ET TURBOREACTEUR INCLUANT UN TEL TOURILLON
Abstract: front page image
(EN) The invention relates to a trunnion (23) for a high-pressure turbine (11), to be arranged between a shaft of a low-pressure turbine (9) and an inner surface (34) of a seal mounting (26) of the low-pressure turbine (8), the trunnion (23) being characterised in that it includes a drop-launching extension (32) arranged such as to extend opposite a flared portion (33) of the inner surface (34) of the seal mounting (26), such that when the trunnion (23) is rotated about the shaft of the low-pressure turbine (9), oil (H2), which tends to penetrate between the trunnion (23) and the seal mounting (26), is thrown by centrifugal effect from the drop-launching extension (32) toward the flared portion (33) of the inner surface (34) of the seal mounting (26).
(FR) L'invention concerne un tourillon (23) pour turbine haute pression (11), destiné à être disposé entre un arbre de turbine basse pression (9) et une surface interne (34) d'un support de joint (26) de turbine basse pression (8), le tourillon (23) étant caractérisé en ce qu'il comprend une extension lance-goutte (32) agencée pour s'étendre en regard d'une partie évasée (33) de la surface interne (34) du support de joint (26), de manière à ce que lorsque le tourillon (23) est entraîné en rotation autour de l'arbre de turbine basse pression (9), de l'huile (H2) tendant à pénétrer entre le tourillon (23) et le support de joint (26) est projetée par effet centrifuge depuis l'extension lance-goutte (32) vers la partie évasée (33) de la surface interne (34) du support de joint (26).
