Investigation for Distributed defects in Ball bearing using Vibration Signature Analysis– A Review
Kulkarni Sham S, S. B. Wadkar
Abstract :
Rolling element beås are extensively used in most of rotating machinery. For its precise & efficient performance it is necessary to monitor the condition of rolling element beå to avoid catastrophic failure of machinery. This paper presents the review of Viation signature analysis of ball beå with distributed defects on surfaces of inner & outer races. Distributed defects include surface roughness, waviness, off size rolling element & misaligned races. These are caused due to manufacturing error & operating conditions. The main objective of this review is to investigate the effect of distributed defects in ball beå on viation signature. The effect produced by local defects in stationary condition becomes more severe in non-stationary condition & spreads to form distributed defects. Traditional techniques of viation signature analysis are available for the detection of beå fault. But when signals are complex & non stationary, these techniques have limitation to diagnose faulty signal. Wavelet Transform is time frequency analysis method gives better performance for analyzing non- stationary signal various parameters like defect type, defect location & defect size for variable speed & load condition is reviewed.
