Wind turbine bearings
In one aspect, a pitch bearing for coupling a rotor blade to a hub of a wind turbine may include an outer race defining a first outer raceway wall. The first outer raceway wall may define a center of curvature. The pitch bearing may also include an inner race defining a first inner raceway wall. The...

Summary: | In one aspect, a pitch bearing for coupling a rotor blade to a hub of a wind turbine may include an outer race defining a first outer raceway wall. The first outer raceway wall may define a center of curvature. The pitch bearing may also include an inner race defining a first inner raceway wall. The first inner raceway wall may define a center of curvature. In addition, the pitch bearing may include a plurality of roller elements disposed between the first inner and outer raceway walls. Each roller element may define a geometric center. Moreover, the center of curvature for each of the raceway walls may be offset from the geometric center of each roller element. |
