Vibroacoustic evaluation of the rolling bearings technical condition

In the article authors presents results of study, which have on aim qualification of technical state of rolling bearings with vibroacoustics methods. Examined bearings were mounted in rollers of belt conveyor working in coalmine. Research was conducted after certain time of rollers’ operation. For analysis were used vibrations signals, recorded in laboratory, on special test stand. The basis of evaluations was changes in signals caused by damages and wear of bearings.
