Developing the methodology on creating unified criterion for diagnosing the mining machinery equipment defects

In the framework of the research the consolidation of the results on analyzing vibration parameters, registered during operation of electric shovel energy-mechanical equipment (of EKG and ASH type) was fulfilled. It was done in the respect of solving the problem on improving vibration control methodology and developing unified criterion for diagnosing and forecasting technical condition degradation of open-pit excavator dynamic equipment. Methodology for creating the algorithm for unified diagnostic criteria on the basis of mathematical processing of the existing vibro-diagnostic properties during detecting the defects in rolling bearings and jointing sleeves used in designing electric shovels was worked out. The effectiveness of the introduced approach for selecting diagnostic methodology of obtaining initial data suited for developing unified diagnostic criteria was proved. The results showed the effectiveness of the methodological approach for creating the algorithm of developing unified criterion for detecting technical condition and forecasting the degradation processes of rolling bearings and jointing sleeves used in designing electric shovels.
