Zusammenfassung:	This invention concerns a device (40) for separating and collecting two flows (51, 52) of a lubrication fluid for an epicyclic gear train (10) comprising a toothed planetary wheel (11), an external ring gear (12), a planet carrier (20), toothed satellite wheels (30) carried by said planet carrier (20). Said epicyclic gear train (10) is oiled by a lubrication system (50) directing a lubrication fluid mainly toward a first device (25) for rotationally guiding said planet carrier (20) and toward second devices (35) for rotationally guiding said satellite wheels (30). The separation and collection device (40) on the one hand directs a first flow (51) of said lubrication fluid to said second guiding devices (35) and on the other hand directs a second flow (52) of said lubrication fluid (52) flowing by gravity from said first guiding device (25) between two satellite wheels (30) thus preventing the mixture of the two flows (51, 52). La présente invention concerne un dispositif de séparation et de collecte (40) de deux flux (51,52) d'un liquide de lubrification pour un train épicycloïdal d'engrenages (10) comportant une roue planétaire (11) dentée, une couronne externe (12) dentée, un porte-satellites (20), des roues-satellites (30) dentées portées par ledit porte- satellites (20). Ledit train épicycloïdal d'engrenages (10) est lubrifié par un circuit de lubrification (50) dirigeant un liquide de lubrification notamment vers un premier dispositif de guidage (25) en rotation dudit porte-satellites (20) et vers des seconds dispositifs de guidage (35) en rotation desdites roues-satellites (30). Le dispositif de séparation et de collecte (40) permet d'une part d'acheminer un premier flux (51) dudit liquide de lubrification vers lesdits seconds dispositifs de guidage (35) et d'autre part d'acheminer un deuxième flux (52) dudit liquide de lubrification s'écoulant par gravité dudit premier dispositif de guidage (25) entre deux roues-satellites (30) évitant de la sorte le mélange des deux flux (51,52).
