Abstract
A bearing system supports a plurality of turbine blades; each blade being rotatable about a pitch axis relative to a bearing system hub. The hub, comprising a plurality of static frames having a conical structure including two or more legs with openings therebetween, is connected to a main shaft of the turbine. Dynamic frames include a conical structure and two or more legs with openings therebetween. Legs of the static frame pass through openings between the legs of the corresponding dynamic frame, and legs of the dynamic frame pass through openings between legs of the corresponding static frame. Each dynamic frame is connected to one of the blades and is rotationally mounted to the corresponding static frame by a first bearing unit and a second bearing unit, distally arranged along the pitch axis from the first bearing unit. A central hub portion interconnects first shaft sections of the static frames.
