Abstract
A method for manufacturing a pitch bearing or a yaw bearing for a wind turbine includes forming an outer race of the bearing of a base material. The method also includes forming an inner race of the bearing of the base material. Further, one of the inner race or the outer race defines a circumferential surface comprising a plurality of gear teeth. The method further includes arranging the inner race within the outer race. In addition, the method includes providing a plurality of roller elements between the outer and inner races. Moreover, the method includes applying a coating material to at least a portion of the plurality of gear teeth via an additive manufacturing process. The coating material is different than the base material. As such, the coating material provides at least one of increased hardness, strength, or durability to the base material.
