Planetary gearbox

A planetary gearbox comprising:

• a sun gear which is configured to rotate about a rotational axis of the planetary gearbox, the rotational axis defining an axial direction of the planetary gearbox;
• a plurality of planet gears which are driven by the sun gear, each planet gear comprising an inner bore, an axially forward face side and an axially rearward face side;
• a ring gear, the planet gears meshing with the ring gear;
• and
• a plurality of journal bearing pins, each of the journal bearing pins being located in an inner bore of one of the planet gears, wherein in each case a journal bearing pin and a planet gear form a journal bearing;
• wherein at its axially forward face side and/or at its axially rearward face side, each planet gear forms a recess that extends towards a mid-plane of the planet gear;
• wherein the planet gear forms a protrusion at its axially forward face side and/or at its axially rearward face side, the protrusion having an axial extent and a radial extent, wherein the radial extent is limited at the respective face side to the area between the planet gear inner bore and the radial inner limit of the respective recess in the planet gear, and wherein the protrusion is configured to provide for a flow path for oil emerging from the journal bearing that guides the oil away from the journal bearing in a direction having an axial component;
• wherein the protrusion has a radially inner underside, a radially outer top side, and an axially outer end forming a transition between the underside and the top side, wherein the underside of the protrusion provides for an initial flow path of the oil emerging from the journal bearing;
• and
• wherein the underside of the protrusion comprises a sloped surface extending at an angle with respect to the axial direction.
