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

Abstract

The disclosure concerns a wind turbine, comprising: a hub with a hollow cylindrical region with a mean circumference UN; 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 UR; 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 UNB coaxially 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 URB coaxially to the blade bearing. The disclosure achieves the fundamental object in that a first radial offset V1 is formed between the circumference UN and the circumference UNB, and/or a second radial offset V2 is formed between the circumference URB and the circumference UR. In a further aspect, the disclosure achieves the fundamental object with a wind turbine rotor blade and a rotor blade bearing.
