Abstract
A method for detecting a load distribution in a roller bearing having at least one row of rollers and a strain sensor attached to a first ring, wherein the first ring is configured to rotate relative to a second ring. The method comprises steps of: (a) detecting peak heights and peak positions in roller load induced strain signals obtained from the strain sensor, and (b) calculating a load acting on at least one angle range of the second ring using peak heights of a plurality of peak positions falling in the angle range.
