Abstract
A planetary stage of a planetary gear unit with a gearbox housing includes a ring gear, at least one planet gear, and a sun gear, which are rotatably positioned. The ring gear is connected via a tappet to a sun gear shaft of an upstream planetary gear stage, and is rotatably mounted in the gearbox housing. The planetary gear unit exhibits increased robustness by connecting the ring gear on a side opposite the tappet to a ring gear support that is seated in the gearbox housing.
