description A large planetary gear system forming the input stage of a wind turbine power generator, has one or more of the planetary gears with gear teeth having contact surfaces from which the asperity peaks have been removed prior to run-in or installation. The resulting gear contact surfaces have an improved material ratio (Rmr) allowing for greater load bearing capacity and power density. Harmful metal debris caused by run-in is also prevented. The gear surfaces may be finished to a surface roughness Ra of less than 0.25 microns and may be specular in appearance.
