A planetary gearbox includes a planet carrier having stop faces, planet journals, planet bearings, planet gears and thrust washers. Each of the planetary gears is arranged on one of the planet journals by one of the planet bearings. Each thrust washer is arranged between the planet carrier and one of the planetary gears. Each thrust washer includes a first washer side and a second washer side facing away from the first washer side, a lower circumferential circular segment, and a wing formation arranged to rest on one of the stop faces. Each washer side includes recessed portions and raised portions, each arranged adjacent to one of the recessed portions. The recessed portions are arranged to supply a lubricant to one of the planet bearings. The wing formation extends from the lower circumferential circular segment outwardly in a tangential direction.
