A Comparative Analysis of Detecting Bearing Fault, Using Infrared Thermography, Vibration Analysis and Air-Borne Sound

Abstract

A comparative analysis has been performed as an effort to obtain a better idea of how the fault is appearing over a rolling bearing. In this paper are presented the results of this analysis between three methods of detecting faults on bearings: infrared thermography, vibration analysis and air-borne sound. Those methods are applied on a specific rolling bearing and developed on an experimental set up. The conducted experiment depicted that this comparison is feasible as the results of each method are relevant.
