Lubrication of a planet-carrier for a mechanical reduction gear of a turbine engine, in particular of an aircraft

A planet-carrier for a mechanical reduction gear of a turbine engine, comprising:

• a cage defining an internal housing configured to receive a central sun gear with an axis of rotation X, and an annular row of planet gears arranged around the central sun gear, the cage comprising:
• two annular radial walls that are radial with respect to the axis of rotation X, and connected to one another at their outer periphery by a cylindrical wall of the axis of rotation X, at least one of these two annular radial walls comprising a plurality of planet gear mounting orifices, and the cylindrical wall comprising a plurality of through-holes configured to receive the annular row of planet gears so that they engage with a ring gear, which is configured to extend around the annular row of planet gears and the cage;
• and
• an annular distributor of lubricating oil formed of a single part and secured to an inner periphery of one of the two annular radial walls of the cage, so as to define, together with the one of the two annular radial walls, two annular chambers which are independent and sealed to oil circulation.
