Abstract

Est concerné un boitier de relais d’accessoires de turbomachine comprenant un arbre (17) rotatif présentant une surface annulaire (17a) autour de l’axe. Un ensemble d’étanchéité (19) est monté entre un carter et l’arbre, et comprend un élément principal (22) annulaire monté sur l’arbre, venant en appui avant (24) contre une surface complémentaire (250) de l’arbre et qui présente une gorge radialement interne, avec un joint monté dans la gorge. Au moins un doigt (29) s’étend jusqu’au-delà de la surface d’appui (24) de l’élément principal (22) et est engagé dans un logement (30) de l’arbre (17), ou inversement. Figure pour l’abrégé : Figure 4This concerns a turbomachine accessory relay box comprising a rotating shaft (17) having an annular surface (17a) around the axis. A sealing assembly (19) is mounted between a casing and the shaft, and comprises an annular main element (22) mounted on the shaft, bearing front (24) against a complementary surface (250) of the shaft and which has a radially internal groove, with a seal mounted in the groove. At least one finger (29) extends beyond the bearing surface (24) of the main element (22) and is engaged in a housing (30) of the shaft (17), or Conversely. Figure for abstract: Figure 4
