A planetary gear (1) comprising a first fixed ring gear (3) and a second, adjacent rotationally mounted ring gear (7) whereby both ring gears have slightly conical toothing (6,8) with slightly different numbers of teeth located opposite the drive axle (17). The planetary gear also comprises at least one planetary wheel (9) which is driven by a sun wheel (15) and consists of two conical toothed areas (10,11) corresponding to the two ring gears. Said areas engage with the toothing of one of the ring gears (3,7) and both have the same number of teeth. In order to simplify production of the planetary wheels, taking into account the different lines of action on both ring gears, the toothing (6,8) of both ring gears (3,7) and the toothed areas (6,8) of the planetary wheels (9) have the same module and the toothed areas (10, 11) match each other in such a way that a smooth transition occurs beween said areas (10,11). |
