Abstract

Turbomachine (1) d’aéronef, comportant un arbre d’entraînement d’une soufflante (S) par l’intermédiaire d’un réducteur mécanique (6), ce réducteur comportant un solaire (7), une couronne (9), et des satellites (8) qui sont engrenés avec le solaire et la couronne et qui sont maintenus par un porte-satellites (10),au moins un des éléments choisis parmi le porte-couronne (12) et le porte-satellites (10) étant un élément mobile en rotation,la turbomachine comportant en outre une pompe auxiliaire (20) de lubrification à rotor qui est raccordée à un réservoir d’huile de lubrification et qui est configurée pour lubrifier au moins certaines pièces du réducteur,caractérisée en ce que le rotor (18) de la pompe auxiliaire (20) porte un pignon conique (16) qui est engrené avec une denture conique (14) portée par ledit élément mobile en rotation. Figure pour l'abrégé : Figure 3Aircraft turbomachine (1), comprising a drive shaft of a fan (S) via a mechanical reducer (6), this reducer comprising a sun (7), a ring (9), and satellites (8) which are meshed with the sun and the crown and which are held by a planet carrier (10), at least one of the elements chosen from among the ring carrier (12) and the planet carrier (10) being a rotating member, the turbomachine further comprising an auxiliary rotor lubrication pump (20) which is connected to a lubricating oil reservoir and which is configured to lubricate at least some parts of the reduction gear, characterized in that the rotor (18) of the auxiliary pump (20) carries a bevel gear (16) which is meshed with a bevel toothing (14) carried by said movable element in rotation.
