“…Thermal diagnostics accuracy of bearing assemblies is affected by heating factors from ambient air, adjacent heat sources and solar radiation [9]. Therefore, diagnostics by the temperature measured on the outer surface of the bearing assembly has no practical application [10][11][12][13][14][15]. Modern technologies and technical means of temperature measurement make it possible to perform thermal diagnostics automatically, without manual labour, but only when measuring the temperature of the outer surface of the bearing assembly [16][17][18][19].…”

“…The diagnostic criterion for the limit state of bearings is the excess of the temperature in the friction zone of more than 215-250 °С (RТМ 23.2.74-79 Procedure for accelerated testing of drive lines of agricultural machines). However, direct temperature measurement in the friction zone is practically difficult, therefore, methods of calculating heat flows are used to determine the relationship between the temperature on the outer surface of the bearing assembly and the temperature in the friction zone [14].…”

The purpose of this work is to prove the effectiveness of a practical study of the temperature regime for diagnosing bearing assemblies of mechanical transmissions. Using the example of a two-row roller bearing of the rear support of the intermediate shaft of the vehicle transmission, the temperature in the friction zone under different transmission operating modes on a KAMAZ-5320 was calculated. Finite element analysis of temperature fields made it possible to determine the relationship between the temperature on the outer surface of the bearing assembly and the temperature in the friction zone through the coefficient k=0.327. The zone for temperature measurement -the bearing cover is determined and the maximum temperature of its heating is set. Thermal imaging observations confirmed the effectiveness of the developed method of technical diagnostics of bearings.
