Abstract

This paper focuses on determining the technical condition of a bearing box in the vehicle by means of vibrodiagnostics. In the next step, we determined the technical condition of roller bearings in the bearing box by measuring the vibration signal. One of the possibilities of determining the technical condition, including the location of accelerometers, the arrangement of relevant measured devices, and the analysis of frequency spectrum, is described in the paper. The aim of the experiment was to measure vibrations of the bearings placed in the vehicle bearing box and then to carry out the analysis of the measured data. The second part of the paper presents the analysis of samples of the plastic lubricant used for lubricating the tested roller bearings. For the analysis, we used an AES Spectroil Q100 device which works on the principle of atomic spectral analysis.
