Abstract: Relevance of the work. This article contains the results of vibration parameter monitoring and technical condition assessment of bearings installed on generator groups of electric mining shovels. Analysis of data from complex diagnostics of mechanical vibrations of bearings allowed forecasting the processes of their defect development using new unified diagnostic criteria. The main objective of the work is to use the results of diagnostics by vibration parameters to obtain a forecast of the technical condition of bearings installed in generator groups. It is necessary to prove the feasibility of implementing a single diagnostic criterion for assessing bearings when modeling the processes of their degradation and destruction. Within the framework of this work, a comprehensive analysis of the parameters of mechanical vibrations arising during the operation of dynamic equipment of mining shovels was carried out. To solve this problem, various methods of vibration diagnostics were used, among which the central place was occupied by the results of spectral analysis, excess data and envelope analysis. The results of the assessment and forecasting of the dynamics of the processes of development of rolling bearing defects indicate the effectiveness of the developed methodology for creating unified diagnostic criteria. The results obtained may be useful in implementing the concept of servicing mining machines according to their actual condition, which allows reducing the accident rate in the coal industry by forecasting the occurrence of accidents and minimizing unproductive downtime of the mining equipment in operation.
