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.
