AB - The lubrication of rolling contacts in which one surface has a roughness consisting of periodic transverse or longitudinal ridges has been widely investigated, both theoretically and experimentally. Results of these investigations now permit a substantially complete picture to emerge in which it is possible to characterize the state of lubrication by evaluating and comparing the (minimum) film thickness near the crests of the roughness to the corresponding thickness in the valleys. Crest and valley film thickness were studied over a wide range of non-dimensional speed. Two lubricants were used, both Group I mineral oils with viscosities of 22 and 453 cp and alpha values of 19.8 and 20.4/GPa. The elastostatic and asperity values agreed well with the corresponding measurements but both crest and valley measured film thicknesses exceeded the predictions of equation 4 for higher speeds. This is an abstract of a paper presented at the World Tribology Congress III (Washington, DC 9/12-16/2005).
