The rolling element bearing is one of the most critical components in a machine. Prompt diagnostics of rolling element bearing fault is important to avoid failures. In the present study, defects in rolling element bearings are detected using frequency domain approach. Time domain parameters such as Kurtosis, crest factor etc. have been compared for defect free bearings and defective bearings. The effect of shaft speed on the performance of kurtosis and crest factor is studied. Results from the study shows that these parameters are affected by the shaft speed. Also Performance of kurtosis, crest factor and cepstrum is studied for different conditions of operation of SKF 6205 bearing.

Keywords: Cepstrum, condition monitoring, kurtosis, rolling element bearings, vibration
