Abstract
The invention concerns an epicycloidal gear train () comprising a central pinion (), an outer crown () and satellite pinions () in engagement with the central pinion () and the outer crown () and each mounted freely rotatable on a satellite carrier (), the gear train () comprising an annular cup () being integral with the satellite carrier () and open radially inward. According to the invention, the cup () is divided into a circumferential succession of first basins () of the first oil circuit and second basins () of the second oil circuit, the first basins () being fluidly separated from the second cells () and characterised in that the cup () comprises two annular walls () axially facing, the annular wall () of which is furthest from a median transverse plane () of the gear train () has openings () opening into the second basins ().
