Vibration analysis and comparison of the damaged and undamaged rolling ball bearing

Abstract

Abstract This article deals with vibration analysis and the processing of the vibration signal obtained during the experimental measurement on a rotary shaft at start-up, constant speeds and run-out, with a ball bearing roller. The next step of the research is the introduction and application of mathematical and numerical methods for the processing of input and measured data using diagnostic and mathematical software. The principle of measurement and processing was to compare the results of oscillation of an undamaged bearing with several types of damaged bearings with corresponding deformations in the orbits. The purpose of the research and comparison was to achieve optimal results (in terms of amplitude values, the occurrence of eigenvalue vibrations and the resonance phenomenon) of individual bearings with corresponding impulses in the orbits and to obtain calibration diagrams as a tool for possible prediction of bearings in operation.
