Abstract

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.
