The invention is directed firstly to a blade bearing assembly (1) for the rotatable mounting of a rotor blade, comprising two or more preferably rotationally symmetrical and annular connecting elements (4, 5) having in each case at least one flat mounting side (AN, AB) for the rotational connection, on the one hand, to the common hub of the wind wheel or wind turbine for rotation therewith, and to a rotor blade, on the other hand, in particular wherein the annular connecting elements (4, 5) are aligned in such a manner that the axes of symmetry thereof in each case run coaxially to each other or are aligned with each other and the mounting sides (AN, AB) thereof face away from each other, wherein, furthermore, there is at least one gap (X) between at least two of the connecting elements (4, 5), in which at least one rolling bearing (6, 29) is arranged for the purpose of mounting the connecting elements (4, 5) about a common main rotation axis (2) or axis of symmetry, and is characterized in that the inner lateral surface of at least one connecting element (4) is provided with a toothing (12) which preferably encircles said surface or is formed at least as an annular segment, which connecting element(s) are/is optionally designed to be releasable by means of screw connections (K1, K2) and interchangeable, wherein an opening which is circular in each case is provided in the blade bearing assembly (1) for at least two or three, ideally for up to ten or twelve, eccentrically arranged gearwheels (8), the respective centre points of which are arranged along an imaginary circular path about the main rotation axis (2), at least on one of the two mounting sides (AB), such that the relevant gearwheel (8) can be driven in a rotating manner about a secondary rotation axis (3), which is offset eccentrically in relation to the main rotation axis (2), and meshes with the toothing (12), and therefore a relative position of at least one connecting element (4) in relation to an untoothed connecting element (5) mounted thereon results. |
