The research of rotation frequency influence and technical state condition upon the level of vibration spectrum components of rolling bearings

The paper is aimed at researching the influence of rotation frequency and condition of rolling bearings on the level of vibration spectrum components which corresponds to the frequencies of rolling element bearing defects exposure.

The research is based on a theory of experimental planning using an experimental stand to assign frequency and record vibration signals. Different types of bearings have been subjected to the experiment: regular rolling bearings as well as rolling bearings with artificiality created defects and bearings with defects obtained during long-term operation.

The obtained results show the direct dependence between the level of spectrum components corresponding to the frequencies of rolling bearing defect exposure and rotation frequency. It should be noted, that such sensitive dependence is directly connected with condition of the rolling bearing under analysis

These results laid a foundation for creating mathematical models of rolling bearings vibration used in automatic expert systems for rolling bearing diagnostics.
