    摘要: A rotor blade for a rotor of a wind power installation, to a rotor for a wind power installation, to a wind power installation having a rotor blade and/or having a rotor, and to a method for connection of a rotor blade at a hub of a rotor of a wind power installation. The rotor blade comprises a hub-side end for fastening the rotor blade to a movable part of a blade bearing, wherein a bearing cover is arranged on an outer circumferential surface of the hub-side end of the rotor blade, wherein a portion of the bearing cover that is close to the bearing is further away from the outer circumferential surface of the hub-side end of the rotor blade than a portion of the bearing cover that is remote from the bearing by a multiple.

    摘要: A adjustment unit for an azimuth adjustment and/or for a pitch adjustment of a wind turbine, to an adjustment apparatus, to a pitch adjustment apparatus, to an azimuth adjustment apparatus, to a wind turbine, and to methods for the rotor blade adjustment and wind direction tracking, and to the use of an adjustment unit and/or adjustment apparatus. The adjustment unit for an azimuth adjustment and/or for a pitch adjustment of a wind turbine comprises a drive unit which can be arranged on a first annular flange and has an eccentric shaft, a first engagement element which can be arranged on a circumference of a second annular flange which is arranged such that it can be rotated with respect to the first annular flange, a multiplicity of concavely and convexly configured first cam sections being arranged on a circumferential face of the first engagement element, and a second engagement element, with concave and convex second cam sections which are arranged on a circumferential face and correspond to the first cam sections.
