Two-stage planetary transmission with a fixed transmission case, an input shaft, an output part and a planetary gear set mounted in the case and having a planet carrier and at least one planet gear, which has a first toothing meshing with a sun gear connected to the input shaft and with an external gear arranged in a fixed manner in the case and has a second toothing having a different, preferably smaller, number of teeth to the first toothing and meshing with an external gear connected to the output part. The output part is preferably supported directly in the circumferential wall of the case by means of a rolling-contact bearing arranged between a circumferential wall of the fixed case and the external gear associated with the output part. The rolling-contact bearing is, for example, a single diagonal rolling-contact bearing which is preferably arranged in a plane which passes essentially axially through the centre of the external gear of the output part. |
