Abstract: A blade bearing for mounting a blade of a wind turbine to a hub of the wind turbine comprises inner and outer rings arranged next to each other. One of the inner and outer rings is configured to mount to the blade, and the other is configured to mount to the hub. At least two rows of rolling elements are positioned between the inner and outer rings. Upper and lower rows of the rolling elements are located in respective upper and lower planes. A support structure is secured to the inner ring and extends in a substantially radial direction between the upper and lower planes. The support structure has non-uniform stiffness characteristics in a circumferential direction. A method of manufacturing a blade bearing is also provided.

Abstract: A blade root cover segment suitable for fitting to a wind turbine blade to span a gap between the blade and a spinner cover. The blade root cover segment includes a first end and a second end and comprises: a curved flange for abutting against a correspondingly curved surface of the wind turbine blade; a cover wall extending radially from the flange; and a tensioning band associated with the flange. The tensioning band comprises a first end proximate to the first end of the blade root cover segment and a second end proximate to the second end of the blade root cover segment, and wherein the first end and the second end of the tensioning band include connection means for connecting with and applying tension between a like blade root collar segment. The invention also encompasses a blade root cover comprising a plurality of blade root cover segments. The invention also extends to a method of assembling a blade root cover from a plurality of blade root cover segments.

Abstract: The present invention relates to a hydraulic pitch system for pitching a blade of a wind turbine having a hub by means of a hydraulic fluid. The system comprises at least one hydraulic cylinder for adjusting a pitch angle of the blade, the hydraulic cylinder comprising a pitch piston movable in the hydraulic cylinder, and a first port and a second port arranged on each side of the pitch piston, and an accumulator hydraulically connected to the cylinder. The system further comprises a pitch safety system adapted to maintain the blade in a predetermined pitch angle when a person is entering the hub of the wind turbine for service and/or maintenance, the pitch safety system comprising a first valve which by activation releases a pressure in the hydraulic pitch system by draining off the accumulator for the hydraulic fluid until the pressure has reached a predetermined pressure level.
