THERMAL-ANALYSIS OF NONCIRCULAR BEARINGS

The present work is on prediction of temperature distribution in nonci rcular journal bearings and the surrounding solids. Three forms are st udied, viz. two-lobe, elliptical and orthogonally displaced bearings. For comparison purposes, a circular bearing with two different groove locations is analyzed. The investigation includes the effects of recir culation and oil mixing at the grooves. The cavitation zone has also b een investigated. The work is based on a two-dimensional treatment fol lowing Mc-Callion's approach. The results are presented for various ge ometries of journal bearing configuration, including the conventional circular bearing.
