A planetary transmission with at least one planetary gearset including planetary gears supported on a planetary gear carrier. The planetary carrier has inner teeth, which engage outer teeth of a shaft to form a lock tooth array. To secure the planetary carrier axially on the shaft, the planetary carrier is placed with one axial end against a stop on the shaft and the opposite axial end is fixed axially with a circlip fit into a circlip groove in the shaft. At least one axially adjacent component is supported against the planetary carrier such that an axial bearing is arranged radially and axially adjacent to the circlip and includes a roller group guided in a cage and a first check-disk A second check-disk is arranged radially opposite and at a distance from the circlip in such manner that when assembled, the circlip cannot escape from the circlip groove in the shaft.

A planetary transmission with at least one planetary gearset (1, 1′) having planetary gears (2) mounted for rotating on a planetary gear carrier (3), the planetary gear carrier (3) having inner teeth (4) which mesh with outer teeth (5) of a shaft (6) to form a locking tooth array, the planetary gear carrier (3) is positioned with an axial end abutting against a stop (7) on the shaft (6) and being, at an opposite axial end, axially fixed at an by a circlip (9) inserted in a circlip groove (8) of the shaft (6), at least one axially adjacent component (12, 13) being supported against the planetary gear carrier (3) by an axial bearing (10, 11), the axial bearing (11) being arranged radially and axially adjacent to the circlip (9) and comprising at least one group of rollers (15) guided in a cage (14) and a first check-disk (16) and a second check-disk (17) with the second check-disk (17) being arranged radially opposite and at a radial distance away from the circlip (9) in such manner that, following assembly, the circlip (9) cannot escape out of the circlip groove (8) of the shaft (6).
