Abstract
A planetary gear set with a planet stage revolving in a gear set housing has a planet carrier which is connected in particular to a rotor and has planet web cheeks which are connected to one another by means of webs, and a plurality of planet gears which are mounted in planet gear bearings, which are connected to the planet carrier, and are in engagement on one side with a sun gear and on the other side with a ring gear. The gear set housing is provided with an oil supply channel which is connected to at least one oil-guiding channel in the planet carrier. The lubrication of the meshing engagements is facilitated in the planetary gear set by providing dry sump lubrication. This is achieved in that at least one channel connected to the oil-guiding channel is embedded in each web, said channel being aligned with the meshing engagements between sun gear and planet gear and/or planet gear and ring gear.
