Originální abstrakt

Elastohydrodynamic lubrication (EHL) calculations using the real pressure and real shear dependence of viscosity have revealed that the shear and load dependences of film thickness are often greater than the classical prediction. Experimental measurements have confirmed the increased sensitivity to scale and load; however, the sensitivities are even greater than would be expected from shear-thinning. Time-dependent film thickness measurements and stress-history-dependent flow curves are employed to show that molecular degradation may occur at nominal rolling EHL stress levels and that this degradation affects the film thickness.
