Abstract: A roller bearing assembly for determining loads on a roller bearing includes a roller bearing having coaxial inner and outer rings and an axis of rotation, and a plurality of rollers each having a rotation axis being arranged between the rings. At least one ring has recess for receiving a force-measuring pin. A force-measuring pin is received in the recess. The longitudinal axis of the force-measuring pin extends at least partly along the axis of rotation of the roller bearing. The recess and the force-measuring pin extends into a region, which is under a load, of the ring that has the recess such that at least one vertical projection plane perpendicular to the rotation axis of the rollers extends along the force-measuring pin and a region of maximum load. This allows loads to be reliably measured.

Abstract: A rolling bearing arrangement (1) for a transmission (2) of a wind turbine, including a rolling bearing (3) with an outer ring (4), an inner ring (5) and a plurality of rolling bodies (6) rolling between the outer ring (4) and the inner ring (5), the outer ring (4) and/or the inner ring (5) including at least one sensor element (9) for detecting and monitoring a state variable, the at least one sensor element (6) having a load measuring bolt (7) with at least one strain gauge (8) and being directly positioned in a force flow path of the state variable, the state variable being at least a bearing preload of the rolling bearing (3).
