The disclosure concerns a wind turbine, comprising: a hub with a hollow cylindrical region with a mean circumference U; at least one rotor blade mounted rotatably on the hub, with a blade laminate which extends in the longitudinal direction of the rotor blade and at least in portions forms a hollow cylinder with a mean circumference U; and at least one blade bearing for mounting the rotor blade on the hub, with a first bearing ring which is arranged on the hub side and connected by means of a first flange connection to a rotor hub flange formed on a rotor-blade side end portion of the hub, wherein the first flange connection has at least one hub longitudinal bolt which is arranged on a circumference Ucoaxially to the blade bearing; and a second bearing ring which is arranged on the rotor blade side and connected by means of a second flange connection to a rotor blade flange formed on a hub-side end portion of the rotor blade, wherein the second flange connection has at least one rotor blade longitudinal bolt which is arranged on a circumference Ucoaxially to the blade bearing. The disclosure achieves the fundamental object in that a first radial offset Vis formed between the circumference Uand the circumference U, and/or a second radial offset Vis formed between the circumference Uand the circumference U. In a further aspect, the disclosure achieves the fundamental object with a wind turbine rotor blade and a rotor blade bearing.

Wind turbine, wind turbine rotor blade, and blade bearing for a wind turbine

Provided is a wind turbine rotor blade with a longitudinal direction, at least one first rotor blade section with a first front side and one second rotor blade section with a second front side and a separation point between the first and second rotor blade sections. The first and second front sides abut against each other at the separation point. The first front side has a plurality of first recesses, and the second front side has a plurality of second recesses. Further provided is a fastening unit, which is designed to fasten the first and second rotor blade sections to each other at the separation point. The fastening unit has a plurality of first inserts made out of metal, which are arranged in the first recesses, and a plurality of second inserts made out of metal, which are arranged in the second recesses. The first inserts each have a first end and a second end. The second inserts each have a first end and a second end. The first ends of the first and second inserts are each arranged at the separation point. The fastening unit has a plurality of clamping units, which are suitable for bracing the first and second inserts against each other, wherein the respective first ends of the first and second inserts abut against each another and are braced against each other in the braced state.
