Abstract

The article presents a description of the design and the results of numerical studies of static features of a single pad of the fluid pivot tilting pad journal bearing. The authors describe a system of equations for the non-isothermal flow of lubricant in a hydrodynamic lubricant film; the conditions for the transition of the pad to an equilibrium mode; the flow of lubricating fluid in a hydrostatic recess. Moreover, the change in the pressure of the lubricant film along the length of the pads is illustrated depending on the magnitude of the relative eccentricity. Therefore, the features of the bearing operation mode are determined, in which a complete or unilateral “ascent” of the pad is observed.
