Abstract
A wavelet transform based technique has been presented to process the contaminated acoustic signal and diagnose defect in the rotating element. Experiments were conducted on cage ball bearing. Compared to the bearing with no missing ball, there is a sudden variation in acoustic emission when missing ball position comes in front of the mike while rotation. Exact position of the missing balls was determined from the analyzed signal and verified by physical examination.
