Abstract: Rolling element bearings are widely used as low friction joints between rotating machine components. In industrial applications, bearings are considered as critical mechanical components and a defect in such a bearing, unless detected in time, causes malfunction and may even lead to catastrophic failure of the machinery. The research work presented focuses upon the detection of a localized defect in a double row ball bearing using vibration analysis. For bearing analysis, frequency domain approach is taken followed by experimentation for the detection of vibration signal in which single point defects are artificially created on ball, inner race and outer race, then for vibration response these defected double row ball bearings are tested under different speed and loading conditions, and resulting vibration signals are then processed using considered vibration-based techniques in frequency domain. DOE method like Response Surface Method (RSM) is used as a medium for fault detection. These results are given by graphs with like contour plot and surface plot.
