摘要: The invention relates to a method including the steps of: acquiring current vibration signal (Vc) of an engine component mechanical across set measuring period P changes in shaft speed N; capturing during P; synchronizing relative transforming into frequency for obtaining spectrum lines arranged according calculating mean amplitude order obtain signature (Sc); deviation ratio (∆) between (Sc) and healthy reference (Ss); comparing defect indicators predetermined database, listing theoretical damage bearings so as determine potential roller bearing.
