Abstract

Wind turbine, comprising a bedframe (2) having a cylindrical frame connection flange (11) and shaft (3) having a cylindrical shaft connection flange (16), 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), wherein

the frame connection flange (11) is provided with a first row (Ia) of first through bores arranged at an outer first frame radius and the shaft connection flange (16) is provided with a first row (Ib) of first threaded blind bores (21) arranged at an outer first shaft radius which corresponds to the first outer frame radius,the frame connection flange (11) is provided with a second row (IIa) of second threaded blind bores (26) arranged at an intermediate second frame radius and the shaft connection flange (16) is provided with a second row (IIb) of second through bores (27) arranged at an intermediate second shaft radius which corresponds to the intermediate second frame radius,the frame connection flange (11) is provided with a third row (IIIa) of third threaded blind bores (31) arranged at an inner third frame radius and the shaft connection flange (16) is provided with a third row (IIIb) of third through bores (32) arranged at an inner third shaft radius which corresponds to the inner third frame radius,wherein a through bore is flush with a threaded bore and a screw connection (22, 28, 33) extends through the through bore and is screwed into the threaded blind bore.
