Critical Study on Applications of the Theory of Continuous Oil Film Lubrication of a Radial Sliding Bearing for Three Combined Conditions

The theory of lubrication of a radial sliding bearing is extended to three cases: the shaft neck rotation
and bush rotation bearing, the rotating load-bearing, and the floating sleeve bearing. For the bearing
with rotating shaft neck and rotating bush, fixing the observer at the bushing can enable the
determination, in a simple and more accurate manner, of the bearing capacity of the bearing with the
rotating load. As long as a rotating load exists, whirl exists; if the shaft rotation speed is 2 times the
load rotation speed, then the eccentricity reaches the maximum.
