Lubrication and roughness
L. Burstein, Technion-IIT, Haifa, Israel
Abstract:
This chapter introduces the basics of hydrodynamic lubrication theory and highlights its application to some machine parts with un-roughened (slider and cylindrical journal bearings) and roughened surfaces (parallel parts in relative motion). It first presents a theoretical analysis and results for two-dimensional sinusoidal and triangular wave roughened surfaces.
Key words
hydrodynamic lubrication

3.1 Introduction
From long ago to the present, lubrication has been an effective practical means for two simultaneous purposes: reduced friction losses and a longer service life ...
