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.
Claims16
A segmented pitch ring for use in a blade pitch system of a wind turbine, the segmented pitch ring comprising one or more rolled segments and one or more casted segments, wherein the one or more rolled segments are not casted, and wherein the one or more casted segments are not rolled, and wherein the rolled and casted segments are arc-shaped or comprise arc-shaped sections that in combination define a substantially circular circumference of the pitch ring.
A segmented pitch ring for use in a blade pitch system of a wind turbine, the segmented pitch ring comprising at least one rolled segment and at least one casted segment, wherein the one or more rolled segments are not casted, and wherein the one or more casted segments are not rolled, and wherein the at least one rolled segment is different from the at least one casted segment in shape, material, or material property.
