THE EFFECT OF LUBRICATION ON SURFACE ROUGHNESS CHANGE OF ROLLING BEARING ELEMENTS
Journal Title: Tribologia - Year 2012, Vol 244, Issue 4
Abstract
The paper considers the problem of surface layer change during work. The recent studies of changes in roughness structure of bearing elements surface are the result of work on the STBL-02 tester (where the friction pair is a model of a cylindrical roller bearings). The study was conducted on three groups of roller bearings, which worked in different conditions of lubrication. It was therefore considered an important influence of lubrication on the changes of the surface roughness parameters. Analysing the test results, it can be stated that, for the rollers working in conditions of fluid friction, the Rvk and Rpk parameters increase with time, and for the rollers working in boundary friction, the initial value of these parameters decreased in the formation of the equilibrium roughness.
