1. Introduction
During the last decades many theoretical and experimental works have been directed towards the analysis of elastohy-
drodynamic lubrication in line and point contacts. In these works the lubrication of spherical and cylindrical bodies was
investigated, and on the basis of the obtained results equations were devel
