1. A planetary gearset comprising a gear arrangement comprising:
a centrally arranged sun gear arranged to be rotationally fixed to a drive shaft,
a set of planet gears distributed circumferentially around and meshing with the sun gear,
a ring gear member extending circumferentially around the planet gears and being provided with a ring gear meshing with the planet gears,
a set of planet gear shafts, each arranged centrally in and connected to a corresponding planet gear
a set of planet gear bearings, each arranged between a corresponding planet gear shaft and its corresponding planet gear for rotatably connecting the planet gear to the planet gear shaft,
wherein each planet gear shaft comprises a planet gear shaft channel with an inlet opening and an outlet opening for feeding of a lubricant to the planet gear bearing,
a planet carrier connected to the set of planet gears via the planet gear shafts,
wherein
each planet gear shaft extends in an axial direction from the planet gear through the planet carrier and comprises a protruding portion that protrudes out from the planet carrier on an opposite side of the planet carrier in relation to the planet gear, wherein the protruding portion comprises the inlet opening,
wherein the planet gear shaft channel comprises an axially extending planet gear shaft main channel and a planet gear shaft inlet channel connecting the planet gear shaft main channel to the inlet opening, wherein the inlet opening is arranged facing in a radial direction in a planet gear shaft envelope surface.
