Influence of the Sliding Speed on the Elastohydrodynamic Regime

Abstract

The study of the elastohydrodynamic (EHD) lubrication regime is characterristic for the heavily loaded gears and can be modeled on a two disk (SAE) rig. It is very important to observe and determine the lubrication regime because a full EHD lubrication regime assures low friction and wear, while a mixt lubrications leads to high wear and traction values that generate surface destruction. The measurements were made for different values of sliding speed, in order to see its influence on film thickness. There were observed also the influences of: load, temperature and rolling speed
