Abstract:
1. A device for targeted adjustment of an angle of incidence of a rotor blade ( 13 ) that is rotatably mounted, at a foot ( 14 ) thereof, on a hub ( 12 ) of a rotor ( 11 ) of a wind power installation ( 10 ), said device comprising a gearing ( 20 , 40 ), a driving toothed wheel ( 21 , 41 ) that meshes with said gearing ( 20 , 40 ), and a lubricating device, which comprises a lubricating pinion ( 22 , 42 ) meshing with the gearing ( 20 ) or the driving toothed wheel ( 41 ) and provides a lubricant reserve ( 25 , 46 ) on at least one defined lubricating tooth ( 24 , 44 , 45 ) of the lubricating pinion ( 22 , 42 ), wherein the lubricating device is configured such that, due to a temporary displacement of the driving toothed wheel ( 21 , 41 ) from an operating position into a lubricating position, the lubricating device can be engaged with a defined point of the gearing ( 20 ) or the driving toothed wheel ( 41 ), respectively previously engaged with the driving toothed wheel ( 21 ) or the gearing ( 20 , 40 ), so as to transfer lubricant, and wherein displacement from an operating position into a lubricating position takes place via a control device, this control device being configured to effect the displacement during continuous operation of the wind power installation.
