Abstract

A rolling bearing, particularly a rotor bearing, or main bearing, for a wind power generating plant, the bearing having at least two mutually concentric rings separated from each other by a gap in which one or more rows of rolling elements roll along raceways on both rings, such that the two rings are rotatable in mutually opposite directions about their common axis, wherein each ring has at least one connection surface for connection to a foundation, wherein the connection surfaces extend parallel to one another and are passed through approximately perpendicularly by a plurality of fastening bores for receiving fastening bolts extending through them or screwed into them, wherein the raceway of at least one rolling-element row is formed on a part separate from the ring concerned and is pushed away from the ring concerned in a direction perpendicular to the connection surfaces, by at least one resilient element.
