摘要

To obtain the best performance of hydrodynamic thrust pad bearing a more complete understanding of its behavior is necessary. Heat transfer effects in lubrication have long been recognized as an important factor in determining the bearing characteristics. This paper emphasizes the importance of considering temperature effects in fixed pad thrust bearing analysis. The analysis presented consists of simultaneous solution of the Reynolds', energy and heat transfer equations for fixed taper sector shaped thrust bearing pads. The heat transfer in the bearing system is resolved through the bearing solids and heat lost though the grooves between pads. Thermo-hydrodynamic performance for such bearing under static loading conditions is presented in charts. It could be found that the load and speed affect considerably the surface temperatures of the bearing surface and hence the bearing performance characteristics. The heat carried away by the moving fluid and heat dissipated through the bearing solids increases the heat content of the control volume and are significantly affected by the runner speed
