Abstract: A bearing construction for rotationally supporting a wind turbine blade relative to a wind turbine hub, comprising a dynamic frame connecting the turbine blade and a static frame connecting the turbine hub. The dynamic frame is rotationally supported relative to the static frame by first and second axially spaced bearings. The dynamic and static frames comprise first and second bearing seats for the first and second bearings, respectively, and a first conical section having a cone base and a cone apex, and two or more frame legs circumferential openings in between. The dynamic and static frames are mutually overlapping, wherein the frame legs of one frame pass through openings between the frame legs of the other frame. The first conical sections of the static frame and the dynamic frame are oriented in the same direction, whereby a bearing seat is provided at the cone apex of each first conical section.

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.
