Abstract

A discussion is given of the results of analytical and experimental studies of the thick-film lubrication of full journal bearings of finite width. The Reynolds differential equation has been solved by a successive approximation method for (a) flooded full journal bearings, (b) full journal bearings with central circumferential grooves, and (c) full journal bearings provided with point sources of lubricant. Calculations were made on the variation of the journal eccentricity, load-carrying capacity, and friction coefficients with the Sommerfeld dimensionless variable for the three cases and for different bearing widths. Direct experimental tests are described which confirmed the theoretical predictions for bearings fed with lubricant at point sources.
