Experimental investigation of porous metal bearings

Abstract

Self lubricated sliding bearings production and investigations are still in great expansion because of their very practical maintenance and very long operating life. This is probably the main reason for their common use in most of modern micromechanics, automotive and household machines, where they are taking a leader position. The best example is porous metal bearing, which is been made by sintering process as a product of powder metallurgy. Experimental investigations are very important for this kind of bearings because is represents the best way for friction and wear process determination in their operating life. The aim of the paper is to present a way of experiments realization using own projected test rig with modern portable DAQ equipment. In addition here are been presented some results of experimental investigations of porous metal bearings following by their analysis with conclusions and recommendations for their further use and exploitation.
