Abstract

A planetary gear bearing arrangement, including a planet carrier provided with a fixed bearing axis on which a planet gear is rotatably mounted via a sliding bearing that has a first antifriction layer on the axis side and a second antifriction layer on the gear side, wherein one of the two antifriction layers (8, 11) is created on a surface (10, 19) which is at least partially domed in the sliding region to reduce the edge pressure.
