| Popis: | The reliability and performance of technological equipment largely depends on timely and reliable diagnostics of less durable assembly units, which include rolling bearings. An effective tool for determining state of the mechanical rotational systems on rolling bearings is vibration diagnostics. The variety vibration diagnostic method which are used on practise is due to the complexity extracting an informative component for estimation and predicting the state of rolling bearings from the general vibration signal of the study unit. The article is dedicated information content study of narrow frequency ranges of the vibration signal operation bearing assemblies paper machines and their use as diagnostic parameters for vibration diagnostics of rolling bearings. The paper presents the analysis results of vibration diagnostics existing methods of bearing assemblies of the technological equipment and establishes the determination defects in rolling bearings by changing the vibration level on the characteristic frequencies components of the vibration spectrum and the bypass spectrum provides more specific information about the nature damage of the bearing and its operation. On the processing experimental data base i.e. the average vibration velocity spectra signal taken from the bearing assembly paper machine, we offer a relative indicator for current state bearing estimation and its state prediction progress, which helps to make a decision on the suitability or unsuitability bearing. |
