Abstract
The present invention provides a segmented pitch ring for use in a blade pitch system of a wind turbine. The segmented pitch ring is formed of a plurality of segments manufactured by different processes. In particular, one or more of the segments are formed by a rolling process, and one or more of the segments are formed by a casting process. The segments are arc-shaped or include arc-shaped sections that in combination define a substantially circular circumference of the pitch ring.
