Abstract

The planet carrier has a middle radial flange connected on either side to two lateral radial flanges by two respective sets of ribs of equal number. The ribs are spaced around the planet carrier and extend longitudinally and radially. Each pair of adjacent ribs of each set delimits a recess in conjunction with the middle flange and the corresponding lateral flange. The recesses on either side of the middle flange communicate with each other through respective apertures in the middle flange. One set of recesses is to accommodate short planet wheels, while the apertures allow long planet wheels-meshing with the short planet wheels -- to be mounted between the lateral flanges.
