The thermal state of the sliding bearings has a great influence in calculating the dynamics of the flexible rotor of the turbo-compressor. Experimental studies have shown that the temperature difference between the turbine and compressor bearings can reach twenty degrees. In addition, the temperature is unevenly distributed across the lubricating layer. It increases in the area of elevated pressure. The task of assessing the thermal state of the rotor plain bearings is relevant. The effect of eccentricity on the pressure distribution in a thin lubricating layer of a non-Newtonian fluid was considered. The distribution of temperatures and pressures in the lubricant layer was constructed taking into account the rheological properties of the lubricant. The boundary conditions that were used to solve the problem were taken from the experiment. The results will be used to solve the problem of the dynamics of the turbocharger rotor.
