| 摘要 |
The invention relates to embodiments of a planetary gearbox (30) comprising at least one planetary gear (34) having a planetary gear toothing for meshing with a ring gear (68); and a ring gear (68) having a ring gear toothing which is in meshed engagement with the planetary gear toothing of the planetary gear (34). The planetary gearbox (30) is characterised in that in the planetary gear (34) a planetary gear contact surface (93-2) is constructed axially offset with respect to the planetary gear toothing, and that in the ring gear (68) ring gear contact surface (93-1) corresponding to the planetary gear contact surface (93-2) is constructed axially offset with respect to the ring gear toothing, wherein the planetary gear contact surface (93-2) and the ring gear contact surface (93-1) roll on one another during a relative rotation of the planetary gear (34) with respect to the ring gear (68) and form a radial bearing between the ring gear (68) and the planetary gear (34). |
