1. A planetary gearbox, comprising:
a gearbox housing; a central sun wheel supported in the gearbox housing for rotation about a central gearbox axis of rotation, said sun wheel having an external toothing; a hollow wheel arranged in concentric relationship to the central gearbox axis of rotation in the gearbox housing, said hollow wheel having an internal toothing; a planetary carrier mounted in the gearbox housing for rotation about the central gearbox axis of rotation; plural planetary wheels; and planetary wheel bearings configured as slide bearings and configured to mount the planetary wheels on the planetary carrier for rotation about planetary wheel axes of rotation, said planetary wheel bearings having external toothings which engage with the internal toothing of the hollow wheel and the external toothing of the sun wheel, each said planetary wheel bearing comprising two annular bearing elements which are traversed by and held in fixed rotative engagement on a planetary wheel pin, said bearing elements having each an outer peripheral surface shaped to define a cone-shaped sliding surface such that tapered ends of the bearing elements point to one another and a running surface of an inner peripheral surface of the planetary wheel corresponds to the sliding surface of the planetary wheel bearing. |
