VIBRATION ANALYSIS OF ROLLING BEARINGS

Abstract

Machine failures in modern industry led to decreased production and reduced competitiveness. Bearings are important parts in machine construction and their operation has a significant impact on the function and lifespan of the machine as a whole. Vibration measurement is the main non-invasive method for locating and predicting failures of rotating machinery components. The paper details using
vibration analysis, specifically Power Spectral Density (PSD) analysis of acceleration signals from a bearing's damaged inner race, as a cost-effective and reliable method to diagnose bearing failures. This technique identifies deviations from normal vibration patterns in rotating equipment, helping to predict and
prevent potential failures.
