Abstract
Experimental results of steady dimples measured in elliptical glass-steel c ontact under pure sliding conditions are presented. It is found that two di mples connected with a shallower furrow are generated, each near an end of the major radius of the contact ellipse. The complete solution of the corre sponding thermal ellipse. The complete solution of the corresponding therma l elastohydrodynamic lubrication (TEHL) problem is calculated numerically. Good agreement is obtained between the experimental and theoretical results . This agreement can be explained by the temperature-viscosity wedge mechan ism. correctness of this mechanism is demonstrated using additional experim ents with ceramic balls in contact with glass and sapphire disks.
