Abstract
This paper presents results from a study of thermal and elastic effects inthe tilting pad journal bearing. The analysis considers thermal and elastic distortions of the pad, thermal growth of the bearing components, and cross-filmvariations of lubricant viscosity. The computer model is verified against steady-state experimental data gathered from a five-shoe bearing. Calculations indicate that significant changes in bearing and pad clearances may occur as a result of pad, shaft and housing distortions. In some cases, this may lead to an operational preload which is substantially different from that called for in the initial design.
