Abstract

L'invention concerne un engrenage planétaire (1) doté d'au moins un jeu de roues planétaires qui comprend au moins un porte-satellites (2) conçu pour accueillir des axes de roue planétaire (4) disposés de manière décalée les uns par rapport aux autres et sur lequel sont positionnées des roues planétaires (5) montées à rotation. Sous l'effet de la force centrifuge, un lubrifiant, notamment de l'huile, est acheminé à un palier (6) de la roue planétaire (5) au moyen d'un dispositif de guidage (11) associé à des conduits d'admission à l'intérieur de l'axe de roue planétaire (4). Chaque roue planétaire (5) comprend en tant que dispositif de guidage (11) une cuvette collectrice d'huile (12) à structure monobloc, laquelle est logée de manière bloquée en rotation dans un orifice (17) du porte-satellites (2) et qui est montée en position fixe sur le porte-satellites (2) au moyen d'une structure à encliquetage (18). La cuvette collectrice d'huile (12) vient se loger par complémentarité de formes dans un trou borgne (22) de l'axe de roue planétaire (4).
