Abstract
This paper presents data on the maximum oil film pressure and temperature of two-lobe journal bearings with different bore profiles. A bearing with a cylindrical non-continuous bore profile, and another with a pericycloid continuous profile have been evaluated. For an assumed relative length of the bearings, and parallel orientation of the journal and bearing axes, the minimum values of oil film thickness, maximum pressure values, and temperatures of the oil film have been determined. The calculations were carried out on the assumption of an adiabatic oil film and a static equilibrium position of the journal.
