Abstract

The invention relates to a wind turbine gearbox (7), in particular a planetary gearbox, having at least one gear (14) which is mounted on a shaft (19), a sliding surface (26) being disposed between the gear (14) and the shaft (19). The sliding surface (26) is situated on at least one layer (25, 33, 34) of a hardfaced material consisting of a sliding bearing substance. The invention further relatesto a method for producing the wind turbine gearbox (7).

Description

technical field [0001] The invention relates to a wind power plant transmission, a wind power plant equipped with the wind power plant transmission, and a method for producing the wind power plant transmission. Background technique [0002] A planetary gear for generating electricity for a wind power plant is known, for example, from DE 102 60 132 A1. Typically in such planetary gears, likewise described in DE 102 60 132 A1, rolling bearings are used as bearing elements for the planet wheels. However, the prior art also describes plain bearings as support elements, eg EP 1 544 504 A2 or AT 509 624 A1. In this case, a plain bearing bush is usually used as the plain bearing, which is shrunk onto the shaft or pressed into the planet wheel. Replacing such sliding bearings in the event of maintenance or wear is complicated and therefore costly. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art and to prov...
