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.

Abstract: A gearbox assembly for a gas turbine engine includes a hollow gear. The hollow gear has one or more reservoirs configured to store a lubricant and one or more passages configured to supply the lubricant to one or more gear meshes in the gearbox assembly. The hollow gear provides a dampening system configured to absorb vibrations and loading experienced in the gearbox assembly and configured to provide impact resistance for the gearbox assembly.

Abstract: A method for manufacturing a planet gear or a sun gear of a gearbox of a wind turbine includes forming a base of the planet gear via at least one of casting or forging. 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.
