Analysis is present of EHL traction with low-viscosity lubricating oils, which is the case encountered at higher temperatures. Extension is made of the approximate formula already derived by the authors, where it is assumed that viscosity, instead of viscoelasticity, predominates when the limiting Newtonian viscosity in an EHL film falls below a critical value, 10^5 Pas, and an Eyring viscous solution is employed. The rheological parameters representing the traction characteristics of an oil then become the effective viscosity-pressure coefficient and the representative stress, and they are expressed as functions of mean Hertzian pressure and bulk temperature. Calculated results are compared with experimental data obtained on a four-roller machine for two diesters showing close agreement.
