Abstract

Dispositif de déshuilage d'une enceinte de lubrification de turbomachine d'aéronef, en particulier à réducteur, caractérisé en ce qu'il comprend deux arbres (3, 8) coaxiaux délimitant en partie une enceinte de lubrification (E1), lesdits arbres étant engagés partiellement l'un dans l'autre et étant configurés pour tourner à des vitesses différentes, un premier (3) desdits arbres comportant une partie d'extrémité annulaire externe (3a) comportant une rangée annulaires d'ouvertures radiales (37) traversantes configurée pour forcer le passage centrifuge d'air et d'huile à travers elles, un second (8) desdits arbres comportant une partie d'extrémité annulaire interne (8a) engagée dans ladite partie d'extrémité annulaire externe et comportant une rangée annulaire d'orifices radiaux (35) traversants configuré pour former un déshuileur et forcer le passage centripète d'air à travers eux, et des moyens annulaires d'étanchéité (39a, 39b) situés radialement entre lesdites parties d'extrémité annulaires interne et externe, de part et d'autre desdites ouvertures et desdits orifices et aptes à autoriser le passage axial d'air dans l'espace axial (E3) s'étendant entre lesdits moyens annulaires et dans lequel débouchent lesdites ouvertures et lesdits orifices.
