1. A planetary transmission for a wind turbine, comprising:
a bolt having a cylindrical outer surface, and
a planetary gear having a cylindrical inner surface rotatably supported on the outer surface of the bolt,
wherein the cylindrical outer surface of the bolt and the cylindrical inner surface of the planetary gear are configured to function as a plain bearing,
wherein the inner surface of the planetary gear and/or the outer surface of the bolt includes a sliding layer, and
wherein the sliding layer is a cold sprayed layer having a material composition different than a material composition of the planetary gear and a material composition of the bolt.
