Abstract
The presence of defect (s) in a machine is capable of changing its dynamic behavior. In a spectral analysis it is possible to verify changes of amplitudes in specific frequencies, which allows, with the help of some mathematical tools, to characterize the gravity and type of defect (s) present. Bearings, in particular, are fundamental components in rotary machines, which arouses great interest in the accomplishment of researches in order to understand the process of formation and progression of the failures in these components. Defects in bearings may originate from the manufacturing process itself as well as from misuse or natural wear by operating time. In this work a study is carried out to identify the presence of defects in bearings using the classic Hilbert Transform.
