    Abstract: A pitch bearing for coupling a rotor blade to a hub of a wind turbine includes an outer race configured to be coupled to the hub, an inner race rotatable relative to the outer race and configured to be coupled to the rotor blade, and a first plurality of line contact rolling elements. The outer race defines a first outer raceway wall and the inner race defines a first inner raceway wall. The first plurality of line contact rolling elements is disposed between the first inner and outer raceway walls. Each of the plurality of line contact rolling elements defines a predetermined contact angle. The predetermined contact angle is defined as an angle between a reference line extending perpendicular to a longitudinal axis of one of the plurality of line contact rolling elements and a reference line extending parallel to a horizontal plane of the pitch bearing. Further, the predetermined contact angle includes angles between 0 degrees (°) and 90°.

    Abstract: The invention is directed to a rotor blade assembly for a wind turbine designed to mitigate pitch bearing loads. The rotor blade assembly includes a rotor blade, a pitch bearing, and at least one shim plate. The rotor blade includes a body extending between a blade root and a blade tip. The pitch bearing includes an outer race, an inner race, and a plurality of roller elements between the outer race and the inner race. As such, the inner race is rotatable relative to the outer race. The at least one shim plate may be configured between the inner race and the blade root or between the outer race and a hub of the wind turbine so as to mitigate loads experienced by the pitch bearing.

    Abstract: A spacer assembly for a bearing of a wind turbine and/or a bearing assembly for a wind turbine is provided. The bearing assembly includes an outer race, an inner race rotatable relative to the outer race, a plurality of roller elements positioned between the inner and outer race, and a plurality of load-bearing spacers configured between the roller elements. Each of the spacers includes a spacer portion and an extension portion. Thus, each of the spacers is arranged to contact adjacent spacers within the bearing assembly via the extension portion such that the extension portions of the spacers are configured to transfer loads experienced by the bearing assembly rather than the loads passing through the roller elements.
