The invention relates to a
roller bearing arrangement (1, 26, 31, 34, 36, 37), preferably a large-scale
roller bearing with a
diameter of 0.5 m or more, for mounting parts of an
energy system, in particular as blade bearings for a wind
turbine, comprising at least two annular counter-rotatable elements (2, 3), arranged concentrically to one another and one inside another at least in areas, for connecting to counter-rotatable parts of the
energy system. Two counter-rotatable connecting elements (2, 3) are separated from one another by a gap (4) and overlap one another radially, at least in part. Furthermore, at least two rows of rolling bodies (17, 18) are provided in the area of the gap (4) in radially overlapping areas of the annular connecting elements (2, 3), each row rolling along two tracks (19, 20) overlapping one another in the radial direction at least in areas. One or more tracks (19, 20) for rolling bodies (17, 18) are arranged in radially overlapping sections (5, 6) in such a manner that the angle of support, which is enclosed by the connection line between the centres of the contact points of a rolling body (17, 18) with the two tracks thereof opposite the
ring plane, is greater than or equal to 45°, with the result that such an axial
roller bearing is used for transmission of predominantly axially acting force components. At least one additional bearing for transmission of predominantly radially acting force components is provided, the support angle of which is less than 45°, preferably 25° or less, in particular 10° or less, wherein at most such tracks for radial roller bearings, the maximum distance of which perpendicular to the track surface is equal to or less than 25% of the largest distance perpendicular to the track surface between two tracks of an axial roller bearing row, are introduced directly into the annular connection elements (2, 3).
