Planetary gearing and planet pin for a planetary gearing

A planetary gearing, comprising:

• a sun gear rotating about a rotation axis of the planetary gearing and is driven by a sun shaft, wherein the rotation axis defines an axial direction of the planetary gearing,
• a plurality of planet gears that are driven by the sun gear, wherein each planet gear has an axially forward face side and an axially rearward face side,
• a ring gear with which the plurality of planet gears is in engagement,
• and
• a plurality of planet pins, and the planet pins respectively comprise an abutment surface, which comprises an axial forward end and an axial rearward end,
• wherein respectively one planet pin is arranged inside a planet gear, and the planet pin and the planet gear form a lubricated journal bearing,
• and wherein
• the planet pin is provided with an axial bore and has an inner surface that comprises an axially forward end and an axially rearward end,
• wherein
• that the inner diameter of the axial bore of the planet pin varies between the axially forward end and the axially rearward end of the inner surface, and at that has a maximum at least at one axial end, and
• the planet pins respectively form a crowning at their abutment surface in the sense that their outer diameter decreases from a maximum outer diameter towards at least an axial end of the abutment surface, and has a minimum at the axial end.
