Estimating the term…
An impeller (130) for a planet carrier of a planetary gear speed reducer of a turbomachine, said impeller having a generally annular shape and comprising means (158) for supporting axes of rotation of planets of said reducer, said impeller comprising means for lubricating teeth of said planets and bearings of said axes, said lubrication means comprising an annular groove (138) located on the internal periphery of said impeller and opening radially towards the inside, said groove being connected to lubricant supply and/or spray means, characterised in that the impeller comprises dynamic annular sealing means (142, 144) located at the inner periphery of said impeller, on either side of the groove, and configured to interact with a stator (132) of the reducer or of the turbomachine intended to extend inside of and coaxially with the impeller.
A spinning wheel for a planet carrier of a planetary gear speed reducer of a turbine engine, said spinning wheel being integral in rotation with said planet carrier and to be set into rotation around an axis A of rotation of said planet carrier, said spinning wheel having an annular shape around said axis and comprising means for supporting axes of rotation of planets of said reducer, said spinning wheel comprising means for lubricating teeth of said planets and bearings of said axes, said lubrication means comprising an annular groove located on an internal periphery of said spinning wheel and opening radially towards inside said spinning wheel, said groove being connected to lubricant supply and/or spray means, wherein the spinning wheel comprises dynamic annular sealing means located at an inner periphery of said spinning wheel, on either side of said groove, and configured to interact with a stator of the reducer or of the turbine engine.
