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

slider and cylindrical bearings

sinusoidal roughness

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 ...
