Abstract
A series of comprehensive reviews reveals much useful information that has become available during the last ten years and which enables the design of bearings to be placed on a sounder basis. The extended range and utilization of the digital computer has facilitated the solution of both the fundamental equations of lubrication and the optimization of design.
Sufficient information now exists to solve the problem of correct application of journal bearings under conditions of turbulence, transient load, and instability. Gas bearings are being used extensively and the design and stabilization of externally pressurized bearings are described.
The theory of elastohydrodynamic lubrication has proved revealing in the design of cams and has provided understanding of the effect of surface finish on endurance under pitting fatigue conditions.
