Abstract :
The monitoring of the bearings makes it possible to avoid disassembling mechanical systems during their preventive controls and to be able to detect the approach of a failure. The paper describes a mechanical model ruling bearing devices´ defects. The proposed model concerns defects related to surface waviness, flaking defects as well as those due to unbalanced rotor´s effects. The defects´ detection is formulated in the frame of vibratory analysis.
