The construction of rheological models of modern oils, reflecting the dependence of viscosity on temperature and pressure in a thin lubricating layer and the shear rate is of significant importance in calculating heavy-loaded bearings. The system of equations of hydrodynamic lubrication theory and heat transfer is describe based on the behavior of a lubricant layer, concluded between friction surfaces. These surfaces are considered as the boundaries of the lubricating layer. The properties of lubricants affect the characteristics of friction units as much as the geometric factor. However, the parameters of rheological models should be determined based on the experimental data for each grade lubricants. This is an abstract of paper presented at the 2013 STLE Annual Meeting and Exhibition (Detroit, MI 5/5-9/13).
