Low-power-loss bearings for electric utilities. Volume 3. Performance tables and design guidelines for thrust and journal bearings. Final report

Technical Report ·
OSTI ID:5632394
This is the third of a three volume final report on EPRI Research Project RP 1648-1, ''Low Power Loss Bearings for Electric Utilities.'' The objective of the research was to perform an analytical study into the potential for reducing bearing losses through optimization of both journal and thrust bearings. A preliminary economic study indicated that a reduction in bearing losses by 50% for a 500 MWe unit would result in a fuel savings of approximately $130,000/yr for coal fired and $330,000/yr for oil fired, in 1981 dollars. The third volume presents the tabular performance information, based on dimensionless parameters, which can serve as design guidelines and as the basis for estimating power loss, oil flow and temperature rise. The types of bearings covered are the tapered land and floating disc types of thrust bearing, and the circular three-pad, three-lobe and tilting-pad types of journal bearing. For each bearing type, the pertinent parameters and equations are given, the general performance is discussed, a suggested procedure for using the tables to obtain performance information is given, and numerical examples for a typical application are presented. 32 figs., 5 tabs.
