Abstract

Defects in bearings may arise during use or during the manufacturing process such as crack damage, spalling, corrosion, fatigue failure, etc. The detection of the defects is important for condition monitoring as well as quality inspection of bearings. Vibration analysis is the most common method used in monitoring applications since a local defect produces successive impulses at every contact of defect. The aim of this paper is to focus on investigating the position of the local defect on the outer race is changed 0˚, 45˚ and 180˚. The different angular defect position is studied at zero clearance, ε = 0.5, by using the statistical parameters RMS. It can be concluded that the acceleration RMS ratio is more effective in detecting the defect for acceleration response.
