- the planet carrier In order to ensure the lubrication and cooling of the meshing zones of the planet gears and their axes of rotation, it is sufficient, according to the invention, to equip the planet carrier with a cylindrical envelope which surrounds fixed means of supply. oil. The oil supplied by these means is recovered by centrifugal effect in the cylindrical envelope from which it can be conveyed to the meshing zones of the satellite gears and to the axes of these satellite gears without the need to use for this rotary joints.
- lubrication and cooling means are therefore characterized by their simplicity and reliability, as well as by their compatibility with the oil supply means of other stations to be lubricated and cooled in a turbomachine, which makes it possible to install a common oil feed pump for the gearbox and the other stations to be lubricated and cooled.
- the cylindrical envelope comprises radial or substantially radial ducts oil supply sprinklers oriented towards the meshing zones and the axes of the satellite gears.
- the fixed means for supplying oil comprise at least one ramp parallel to the shaft of the central gear and carrying injectors oriented radially towards the cylindrical envelope, the latter comprising annular compartments separated by radial partitions and each connected to conduits supplying nozzles.
- This configuration makes it possible to distribute the oil more evenly and evenly to the different areas to be lubricated and cooled.
- cylindrical envelope and the planet carrier can be positioned axially on either side of the central gear and are connected by axial arms which extend between the planet gears.
- the invention also relates to a turbomachine such as an aircraft engine turbojet, characterized in that it comprises an epicyclic gear train reducer of the type described above, which connects a turbine shaft to one or two propeller drive shafts.

- FIG. 1 shows schematically a known gear reducer with epicyclic gear, mounted in a turbomachine such as an aircraft engine turbojet engine with two counter-rotating propellers which are rotated from a turbine shaft 10 by a reduction gear 12 with an epicyclic gear train substantially comprising a central gear or sun gear 14 that is rotatably connected to the turbine shaft 10, a fixed first outer ring gear 16 mounted on a fixed element 18 of the turbomachine a second mobile outer ring 20 which is fixed at the end of a shaft 22 for rotating one of the propellers of the engine, this shaft extending downstream and being guided in rotation by bearings 24 on a element 26 of the fixed chassis of the engine, the gearbox further comprising planet gears 28 which are engaged with the central pinion 14, with the first fixed outer ring 16 and with ec the second mobile outer ring 20 and which are mounted free to rotate on a planet carrier 30 integral with a shaft 31 which extends downstream for the rotational drive of the second propeller motor.
- a turbomachine such as an aircraft engine turbo
- each planet pinion 28 comprises a first peripheral toothing 32 which is engaged with an internal toothing of the second outer ring 20, and a second toothing 34, coaxial with the first and formed at the upstream end of the planet pinion 28, this second toothing 34 being engaged with an internal toothing of the first fixed ring gear 16.
- Each pinion 28 is also mounted and guided in rotation on a cylindrical support 36 of the planet carrier 30 by means of bearings 38 such as roller bearings for example.
- the lubrication and cooling of the gearbox 12 are provided by nozzles 40, 42, 44 which are carried by fixed elements of the engine and which are oriented towards the meshing zones of the teeth.
