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.
Citation countsare sourced monthly fromand 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 downloadsdisplays 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.
