SUAREZ-BUSTAMANTE, F.A.; TORO-BOTERO, F.M.  e  VELEZ-RESTREPO, J.M.. Effect of the Surface Texture on Friction Thrust Bearing Performance. Ing. invest. y tecnol. [online]. 2012, vol.13, n.1, pp. 97-103. ISSN 1405-7743.

This paper shows a theoretical model which stablishes relations among the operational conditions of a thrust bearing, its conditioned microtopography and the friction coeficient when it works under Hydrodynamic Lubrication conditions. Among the most outstanding results obtained from an exploration made with the model are: building of a map where the performance of these components is characterized and the obtention of some relations among several adimentional groups that show the possiblility to enhance the hydrodynamic lubrication regime for this sort of bearings by artificial conditioning of their surfaces.

Palavras-chave : tribology; sliding bearings; lubrication; textured surfaces; friction.
