The base of the planet gear includes an inner circumferential surface and an outer circumferential surface. Therefore, at least one of the inner circumferential surface or the outer circumferential surface of the planet gear includes a plurality of net or near-net gear teeth. The method also includes applying a coating material to at least a portion of the base of the gear and at least a portion of the plurality of gear teeth of the gear via an additive manufacturing process so as to increase a hardness of the portions of the base and the plurality of gear teeth that includes the coating material.

摘要： The present subject matter is directed to a spacer assembly for a bearing of a wind turbine and/or a bearing assembly for a wind turbine. 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.

摘要： 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.
