METHOD FOR DETECTING AN INCIPIENT DAMAGE IN A BEARING

摘要

A computer implemented method for detecting an incipient damage in a bearing (10) comprises the steps of:- receiving from a plurality of sensors of the bearing (10) a plurality of signals corresponding to a plurality of bursts, each burst being emitted each time an indentation (30) is met during the rotation of the bearing (10) at a contact point between a roller (20) of the bearing (10) and a race (15, 16) of the bearing,- analysing said plurality of signals for locating on the bearing (10) the plurality of indentations (30) corresponding to said plurality of bursts,- generating a map of points (110) on a digital model (100) of the bearing (10) corresponding to the plurality of indentations (30) on the bearing (10), the map of points (110) being registered and updated throughout at least an interval of the lifetime of the bearing,- identifying an incipient damage in the bearing (10) each time the distribution of the points (110) in said map is not random,- generating an incipient damage warning message.
