ABSTRACT:
A device for the targeted adjustment of the angle of incidence of a rotor blade (13) which is rotatably mounted, at the foot (14) thereof, on a hub (12) of a rotor (11) of a wind power installation (10). The device includes a gearing, a driving toothed wheel (21, 41) that meshes with the gearing (20, 40), and a lubricating device. The lubricating device, due to a temporary displacement of the driving toothed wheel (21, 41) from an operating position into a lubricating position, 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 (1) or the gearing (20, 40), so as to transfer lubricant.
