Abstract

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.
