A method for manufacturing a gear assembly of a gearbox in a wind turbine includes providing a pin shaft of the gear assembly. The method also includes depositing material onto an exterior surface of the pin shaft of the gear assembly via an additive manufacturing process driven by a computer numerical control (CNC) device to form a bearing that circumferentially surrounds and adheres to the pin shaft. Further, the method includes providing a gear circumferentially around the bearing to form the gear assembly.

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.

Hybrid-additive gear for a wind turbine gearbox

A combustion liner or component produced through the use of additive manufacturing techniques. The combustion liner or other component may be formed having a feature based optimized cooling circuit at least partially embedded in the thickness of the material. The internal cooling circuit, may be used, along with other benefits, to control the temperature of the component and prevent hot-spots and uneven heat distribution across the surface of the component.

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.

The present disclosure is directed to a gearbox assembly for a wind turbine. The gearbox assembly has a maximal installed width and a maximal transport width. The maximal installed width is greater than the maximal transport width. The gearbox assembly includes at least one torque arm coupled to opposing sides of the gearbox housing. Each of the torque arms includes a proximal end and a distal end. The proximal ends are removably coupled to the exterior surface of the gearbox such that the distance between the distal ends define the maximal installed width. The torque arms are coupled to at least one support element and to a bedplate of the wind turbine.

A nacelle for a wind turbine includes a housing defining an outer wall and a heat transfer assembly embedded at least partially within the outer wall of the housing. The heat transfer assembly includes a heat transfer apparatus having a body with a flow path formed in an outer surface thereof and a working fluid configured to flow through the flow path. The heat transfer apparatus also includes a plate member arranged adjacent to the flow path of the body. As such, the plate member and the outer wall of the housing of the nacelle are configured to conduct heat from the working fluid to ambient air.

A carrier and at least one pin shaft of a gearbox of a wind turbine and method of manufacturing same includes forming the carrier and the pin shaft(s) as a single part or separate components. Further, the method includes forming one or more voids in the pin shaft(s) and/or the carrier via additive manufacturing. As such, the void(s) is configured to increase flexibility of the pin shaft(s)/carrier so as to improve a load distribution thereof.
