THE STUDY OF SLIDE BEARING PROPERTIES INCLUDING THE SURFACE TEXTURE GEOMETRY OF A JOURNAL

摘要

A static friction during a slide bearing's start-up appears to be a complicated process. To deal with the phenomenon, the author uses a molecular-mechanical theory of friction. This paper reports the results that show the influence of a surface geometric structure of a journal on a static friction coefficient, a frictional moment and tangential stresses on a bushing surface. In analysis of results, it can be noticed that machining selection and the accuracy of a journal surface have the significant impact on bearing system during its start-up.
