Abstract:
A process for analyzing roller bearings having a plurality of roller elements which contact an inner ring and an outer ring of the roller bearings, said process comprising the steps of:recording a signal produced by the rolling motion of said roller bearings using a sensor; evaluating the amplitude of the signal in order to determine at least one of a presence of damage and damage depth to a respective running surface of said inner ring and said outer ring, said damage resulting in a depression into said running surface, wherein said evaluating is performed using a dynamic model of the roller bearing, and wherein at least one of several double-sided contact stiffnesses of the rolling elements are taken into account in order to determine a transfer function based on the relation of a force caused by the present damage and a related output signal of the sensor, the sensor signal being taken into account in the evaluation of the signal amplitude.
