Abstract
Bearing plays a vital role in rotating machinery. Many authors studied failure analysis of the bearing experimentally and numerically by creating defects in the outer race, inner race, and rolling element and keeping clearance between shaft-sleeve, sleeve-inner race and outer race-pedestal block. This causes an increase in vibration in the machine as a whole. In this paper square hole with different depths of cut is created on the ball by EDM, and also clearance is developed between the ball and the outer race. Frequency spectra are obtained by FFT Analyzer. The experiment is conducted with different speeds and a single load. Experimental results show that the peak amplitude of vibration increases with an increase in speed. Peak vibrational amplitudes also increase with the increase in the depth of cut for the same clearance. Clearance has little effect in changing vibrational amplitudes. Harmonics in terms of ballspin frequency is clearly observed.
