Descrição: This paper presents the influence of EHD-lubrication on stress fields in the contact area of rolling and sliding mechanical elements. The research is related to the line contacts which usually appear with contacting elements such as gears, roller bearings, wheels etc. The computational analysis was performed using the equivalent model of two contacting cylinders that have the same radii as are the curvature radii of contacting mechanical elements at any point of a real contact. The equivalent cylinders are subjected to normal and tangential traction, determined by the Hertz contact theory with consideration of additional external contact forces arising from the EHD- lubrication conditions. The finite element method is used for numerical computations of the stress fields for different lubrication conditions. The results from such computations provide the basis for determination of the influence of typical lubrication parameters, such as viscosity of lubricant and mean surface velocity of the contacting cylinders on the stress field in contact area. Consequently it is possible to find the optimal lubrication parameters relating to the stress field in the contact area.
