EVALUATION OF LUBRICATION EFFICIENCY BASED ON WEAR DURING VARIABLE LOADS AND SLIDING VELOCITIES

Journal Title: Tribologia - Year 2016, Vol 268, Issue 4

Abstract

The results of the tribological studies on the lubrication efficiency of greases evaluated based on tribological tests performed at varying pressure p and rubbing speed v are presented. For the efficiency criterion, the volume of wear VF(d) obtained from the regression equations of wear was adopted (wear F (d) = f (F, v)). Six different lubricants were tested; two of them were commercial greases, and four of them were compositions based on them, including conventional solid greases (PTFE, tin, copper, and boron nitride). The experiment was carried out on a four-ball extreme pressure tester according to a rotatable design on five levels. For each of the selected lubricants, a regression function was developed that defined wear as a function of rubbing speed and load. The volume of the obtained wear VF(d) was calculated and relevant conclusions were drawn.<br/><br/>
