Thermal deformation of journal bearings operating under high-temperature conditions can have a significant effect on changes in bearing performance. However, no attempt has been made to quantify this amount thermal and link it the performance change bearing. The aim study is investigate quantitative due tilting pad (TPJB) terms preload amount. variable viscosity Reynolds equation energy were co...

The influence of pad facing material on hydrodynamic lubrication in tilting-pad thrustbearings is investigated in terms of pad and oil-film temperatures and oil-film thickness. Two tilting-pad thrust bearings are examined: one with babbitt pad facing, the other with a layer of a PTFE based composite material. Frictional torque, pad, collar and oil-film temperatures and oil-film thicknes...

A kind of distributed hybrid thrust bearing with tilting pad is proposed in this paper, and the influence plate tilt on performance analyzed. The film thickness equation constructed, considering machining error installation synthetically which are main causes tilt. Substituting to classical calculation bearing, time-varying stiffness obtained. angle analyzed through case controlled by change pi...

Heating is inevitable in any bearing operation. This leads to not only the thinning of the lubricant but also could lead to a thermal deformation of the bearing. The present work is an attempt to analyze the influence of thermal deformation on the thermohydrodynamic lubrication of infinitely long tilted pad slider rough bearings. As a consequence of heating the slider is deformed and is assumed...
