Influence of roundness deviation value on bearing vibration level

Abstract

This article investigates the influence of roundness value on vibration level generated by bearing. One of the shape errors playing a key role in bearing?s operation is roundness deviation. Its value directly influence on vibration level generated by bearing. In the paper, the significance and methodology of roundness measurements in reference to profile of rolling surface received in technological process. Experiment consisted of inner rings matching of bearing 6009C3 with variable roundness deviation with outer rings characterized with little variability of mentioned deviation. In the next step bearing vibration level was examined. In the end, obtained results were combined with values of roundness deviation and basing on them, models of linear regression were obtained, also Pearson?s correlation coefficients were calculated.
