Résumé

A brief analysis of the current studies on the thrust hydrodynamic bearing, on the bearing surface of which the texturing is performed, ensuring less wear on the whole tribo-unit is presented. A mathematical model for calculation of the hydro mechanical characteristics of thrust bearing with laser texturing of load surface was developed. The adequacy of the developed mathematical model is demonstrated by comparing of the experimental and theoretical results. An acceptable value of convergence parameter of the multi-grid method and the number of mesh levels, which is applied when performing the calculations, was found by numerical experiments. Comparison of the two possible types of segments was performed: a stair of Rayleigh; a surface with laser texturing. Calculations showed the advantage of the method of laser texturing to increase the load capacity of thrust bearing. Results of calculations showed the advantage of the method of laser texturing for increase of the load capacity of thrust bearing.

Détail

Keywords: thrust bearing; load capacity; laser surface textured; finite difference method; order of convergence.
