A single or multi-step planetary gearing comprises a sun wheel for each speed step which is engaged by a planet carrier having the planetary gears. The planetary carriers with the planetary gears are arranged within a casing having an internal gear which is in meshing engagement with the planetary gears and the carriers are engaged through their internal gearing with the associated sun gears. The casing is closed at one end by a casing cover. The planet gears are mounted on the planet carriers in an overhung position and check shoulders are provided which bear axially against the associated gears which are carried on either the planet carriers or the casing cover. |
