Static characteristics of tri-taper journal bearing
Rao, D. S., Pai, R., & Hargreaves, Douglas J. (2006) Static characteristics of tri-taper journal bearing. In Hargreaves, Douglas J., Kosse, V., & Tan, A. (Eds.) Austrib 06 - International Tribology Conference, 3 - 6 December 2006, Brisbane.
The static characteristics of a tri-taper journal bearing are studied. The geometry is similar to that for a tri-lobe journal bearing and is akin to three-tapered land composite thrust bearings arranged around a bearing circle. There are three lubricant supply grooves equally spaced around the bearing periphery. Each of the three sections consists of equal lengths of the bearing base circle and a section offset from the base circle such that it merges smoothly with the base circle and provides a predetermined depth at or near to the lubricant supply groove. Performance characteristics such as load carrying capacity, power loss and lubricant flow rate of the tri-taper journal bearing are obtained by the solution of the Reynolds equation using a finite difference method and accommodating Jacobsons -Floberg-Olsson boundary conditions for iso-viscous and laminar flow. The lubricant film profile is determined by superimposing the effect of the ramp on the conventional expression for the film thickness in a journal bearing. Typical characteristics obtained are presented which will be useful to the designer.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
