Abstract
The present disclosure is directed to methods for manufacturing a wind turbine slewing ring bearing having an integral stiffener configured to resist deformation of the bearing under a load. More specifically, the present disclosure is directed to methods for manufacturing components of a slewing ring bearing (e.g., an inner, center, and outer race) using near-net-shape (NNS) ring rolling techniques. In particular, the present disclosure is directed to methods for manufacturing slewing ring bearing races, via NNS ring rolling, that are not restricted to conventional (e.g., generally square, rectangular, quadrilateral, trapezoid, quadrilateral) cross-sectional profiles that necessitate attachment of a separate, non-integral stiffener (e.g., a non-integral stiffening plate, stiffening ring, or stiffening assembly).
