The mechanism to adjust the setting angle of a rotor blade, at a wind energy generator, has a rotating lubricating pinion (22) at the rotor hub which meshes with the rim gear (20) or the drive cogwheel. The pinion has a defined lubricating tooth (24) to form a supply of lubricant (25). The peripheral gap between the meshing points of the lubricating pinion and the drive pinion (21) at the rim gear is set so that, when the drive cogwheel is shifted from a working position into a lubrication position, a dose of lubricant is transferred before meshing again with the rim gear. |
