Sažetak
What is analysed is influence of diagonal roughness of the strip on dressing processeswith lubricants. The analysis begins with Reynolds differential equation for lubricating, in which diagonal roughness of the strip is incorporated. In the estimation, the height of lubricant on the strip is taken into account, as well as its influence on the height of lubricant at the inlet section of the deformation zone. The research has shown that diagonal roughness has a twofold influence on the height of lubricant at the inlet section of the deformation zone. For small roughness of the strip the height of lubricant layer has a tendency of slight decreasing related to the nominal height (when the process is described by smoothness of surfacess) but with an increase of roughness, the thickness of lubricant layer increases further to. The nominal height of lubricant is considered to be the case of changing the concave surface into the convex one, which seems to look straight as if the process is described by smoothness of surfaces. The basis of the analysis was the Monte-Carlo numerical method, and an approximate analytical solution, that gave good coinciding in comparison with the numerical method, was carried out.
