Abstract
The invention relates to a rolling bearing arrangement (1, 26, 31, 34, 36, 37), preferably a large rolling bearing with a diameter of 0.5 or more, for mounting parts of an energy system, in particular as blade bearings for a wind turbine, comprising at least two relatively rotatable annular elements (2, 3) arranged concentrically with one another and at least regionally inside one another, for connection to relatively rotatable parts of the energy system, wherein two relatively rotatable connecting elements (2, 3) are separated from each other by a gap (4) and at least partially overlap each other in the radial direction, wherein, further, provided in the region of the gap (4) in radially overlapping regions of the annular connecting elements (2, 3) are at least two rows of rolling elements (17, 18), each of which rolls along a respective two raceways (19, 20) that overlap each other at least regionally in the radial direction, wherein one or more raceways (19, 20) for rolling elements (17, 18) are disposed in radially overlapping sections (5, 6) in such fashion that the contact angle which the connecting line between the centers of the points of contact of a rolling element (17, 1…
