Abstract:
1. Method for dynamic measurement of the radial deformation of a bearing ring of a rolling bearing for a rotating element having inner and outer bearing rings and rolling bodies therebetween, comprising the steps of: fixing a glass fiber segment of a fiber optic sensor in or on the periphery of one of the bearing rings with the length of the glass fiber segment extending in a circumferential direction around the periphery of said one of the bearing rings joined to a peripheral surface thereof, injecting a light signal which is generated by a light source into the glass fiber segment, detecting the light signal passing through the glass fiber segment with a detector, determining longitudinal deformation of the glass fiber segment from a change of at least one parameter of the detected light signal passing through the glass fiber segment, and determining a corresponding radial deformation of the bearing ring from the longitudinal deformation determined.
