Abstract
The partial texturing of bearing surfaces with different shapes of textures and at different locations is an effective approach to improve the performance of bearings. The present study examines the effects of texture configuration on improvement in load capacity and reduction in friction coefficient for slider and journal bearing. This work presents nondimensional pressure expressions for the partially textured slider and journal bearing. The nondimensional pressure expressions are derived taking into consideration of texture geometry and extent of partial texture on the bearing surface. The Reynolds boundary conditions are used in the analysis to predict nondimensional load capacity and coefficient of friction. Even for nominally parallel surfaces, partial texturing of bearing surfaces has a potential to generate load carrying capacity and reduce coefficient of friction.
