Reconstruction of the Instantaneous Angular Speed Variations caused by a spall defect on a rolling bearing outer ring correlated with the length of the defect

Résumé

In the framework of monitoring of rotating machinery, this paper proposes a simple signal processing tool to re- construct the Instantaneous Angular Speed (IAS) variations caused by the presence of spalled bearing. This tool is applied to signals obtained on a specific test bench. Associated with an angular sampling, the analysis of these variations can identify the length of the defect whatever the mode of operation, particularly in non-stationary op- erating conditions in rotation speed.
