The objective of this study is to analyze the possibility of Thermography aid predictive maintenance to detect mechanical failures in rigid a career unshielded ball bearings. Therefore, eight samples were prepared containing various flaws in the tracks of the inner and outer rings of the bearings. Subsequently, each bearing sample was coupled to a bearing with the shaft and motor, positioned on the inertial table. Then the qualitative and quantitative thermography measurement probes associated with the collection of mechanical vibration data were prepared. The results show that it is possible to see the temperature variations associated with mechanical failures introduced compared to records timefrequency vibration spectrum.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
