Experimental Investigation of Ball Bearing for Vibration Analysis

Vibration analysis is widely used for ball bearing prognostics to monitor the vibration signal. The measurement of vibration and their signal analysis plays an important role for identification of defect. Every defect gives characteristic vibration in the ball bearings. The careful observation of vibration spectra may provide worthful information about defects developed in the bearing. In this paper a test rig is used and a new two—wheeler front wheel axle bearing is installed. The bearings run under constant speed and various loading conditions. The effect of bearing conditions on the constant speed and various loading conditions are studied. When irregularities are detected in the statistical measures the vibration spectrum is obtained and examined to determine where the defect is on the running surfaces.
