Abstract

In order in the planet gearing to achieve uniform power division by distributing the torque of the sun wheels to the planet wheels, the planet carriers (19, 27) of the gearing stages preceding the last gearing stage and the inner sun wheels (25, 35) of the gearing stages following the first gearing stage are radially unsupported and are coupled together rotationally by means of a respective coupling part which compensates centre deviations. The radially unsupported planet carriers (19, 27) and the radially unsupported inner sun wheels (25, 35) each have a groove (22, 30 32, 41) on their mutually facing sides. On each of its faces, the radially unsupported coupling part has a strip, one of these strips being in engagement with the groove (22, 30) of the adjacent planet carrier (19, 27) and the other being in engagement with the groove (32, 41) of the adjacent inner sun wheel (25, 35). By means of these couplings, it is possible to achieve lower production costs and a smaller overall length.
