    摘要: A pitch bearing for coupling a rotor blade to a hub of a wind turbine includes an outer race mountable to the hub and an inner race rotatable relative to the outer race and mountable to the rotor blade. The inner race is formed by first and second ring components, each of the first and second ring components having an outer annular face and an inner annular face. The first and second ring components are joined together at the inner annular faces such that the inner annular faces are opposed and opposite each other. A layer of friction enhancing material is inserted/disposed between the opposed inner annular faces, the friction enhancing material including an abrasive particulate component that increases a coefficient of friction to minimize slippage between the first and second ring components.
