A wind turbine includes a bedframe having a frame connection flange and shaft having a shaft connection flange, which is fixated to the frame connection flange. The frame connection flange includes through bores at an outer first frame radius, threaded blind bores at an intermediate second frame radius, threaded blind bores at an inner third frame radius. The shaft connection flange includes threaded blind bores at an outer first shaft radius that corresponds with the first outer frame radius, second through bores at an intermediate second shaft radius that corresponds with the intermediate second frame radius, and third through bores at an inner third shaft radius that corresponds with the inner third frame radius, wherein a through bore is flush with a threaded bore and a screw connection extends through the through bore and is screwed into the threaded blind bore.
A wind turbine, comprising a hollow bedframe (2) having a cylindrical frame connection flange (11) with a frame front face (14) and hollow shaft (3) having a cylindrical shaft connection flange (16) with a shaft front face (19), wherein the shaft connection flange (16) is fixated to the frame connection flange (11) by screw connections arranged in axially extending bores provided in the frame connection flange (11) and the shaft connection flange (15), characterized in that
