Turbochargers structure developments i.e. work of rotating sets in turbochargers with higher rotational speed imposes more on bearing knots. The recommended values of parameters in this paper were introduced to describe bearings with floating rings. The authors used computational examples to show the influence of presented ranges of a relative clearance of the inner bearing and quotients of radial clearances on work parameters of a sliding bearing with a floating ring such as: relative eccentricities, oil films maximum temperatures, oil films maximum pressures, oil films minimal heights, a journal velocity quotient and a floating ring as well as amplitudes of displacements of floating rings in bearing knots of a rotating set in a turbocharger.
Keywords: Turbocharger, rotating unit, oil film force, adiabatic model, eccentricity ratio.
