Abstract
A planetary gear set includes a slide bearing shell arranged on a planet gear axle, a planet gear mounted rotatably on the slide bearing shell and a planet carrier having a recess for receiving the planet gear axle. An axial disk is mounted in a floating manner between a web of the planet carrier and the planet gear in an axial direction and configured flat on an axially outer side facing the web of the planet carrier. A lubricant film between the axial disk and the planet gear ensures during normal operation hydrodynamic operation between the planet gear and the axial disk. A deficient lubrication is present between the axially outer side of the axial disk and the web of the planet carrier.
