Abstract

Moteur (10) comprenant un arbre de rotor, une enceinte à air, une enceinte à lubrifiant comprenant du lubrifiant et au moins un dispositif d’étanchéité (20) disposé entre lesdits enceintes et comprenant un joint radial annulaire (21) associé à une piste de joint (31) portée par un support (30) de piste d’étanchéité dynamique solidaire de l’arbre de rotor (12). Le support (30) de piste d’étanchéité dynamique comprend au moins un canal (37) de distribution du lubrifiant configuré pour récupérer du lubrifiant contenu dans l’enceinte à lubrifiant et le projeter par l’effet de la force centrifuge sur une surface interne d’échange thermique (35a) au niveau d’une zone de projection située axialement à l’extérieur de la piste de joint (31) par rapport à l’enceinte à lubrifiant (15). Figure pour l’abrégé : [Fig 3]Motor (10) comprising a rotor shaft, an air chamber, a lubricant chamber containing lubricant, and at least one sealing device (20) disposed between said chambers and comprising an annular radial seal (21) associated with a seal track (31) carried by a dynamic seal track support (30) integral with the rotor shaft (12). The dynamic seal track support (30) comprises at least one lubricant distribution channel (37) configured to recover lubricant contained in the lubricant chamber and project it by the effect of centrifugal force onto an internal heat exchange surface (35a) at a projection zone located axially outside the seal track (31) relative to the lubricant chamber (15). Figure for abbreviation: [Fig 3]
