Abstract
A sensorized roller of a bearing, the roller having a central bore extending axially therethrough and a sensor module mounted within the bore in a non-fixed manner. The module includes at least four deformation sensors arranged circumferentially around a module center axis, at defined angular intervals. Each deformation sensor measures a radial distance (measured for defined angular positions lying within an angular span of 180°) between the center axis and a radially inner bore surface. The module includes a processor which receives each measured radial distance and calculates a radial load (under static or dynamic conditions) acting on the roller by estimating an offset angle of the fixed reference relative to the radial load direction and by using the estimated offset angle and each measured radial distance as inputs to a mathematical model, describing a deformation radius of the bore as a function of angular position and load dependent parameters.
