To investigate the influence of the oilsupply condition on the lubricating performance of the contact area under the low and middle speed and middle/moderate load conditions,assuming the lubricant as Newtonian and ReeEyring fluid respectively,the thermal line contact elastohydrodynamic lubrication(EHL) models were established by considering the oilsupply condition.With the Elrod algorithm,a full numerical solution of oil film pressure,film thickness and oil film temperature was obtained with the oilsupply quantity as an input parameter.Results show that,with the decreasing of the oilsupply,the position of the airoil interface in the inlet approaches to the Hertzian contact area gradually.When the oilsupply keeps contant,with the increasing of velocity and load,the position of the airoil interface in the inlet moves toward the Hertzian contact area and the starvation becomes more severe.The central and minimum film thickness is increased with the increasing of oilsupply,and the central film thickness is more susceptible to the effect of oil supply.Under starved lubrication condition,the oil temperature caused by Newtonian fluid is much higher than that of ReeEyring fluid.With the increasing of oilsupply,the maximum oil temperature of the ReeEyring fluid is increased,while the maximum oil temperature of the Newtonian fluid is decreased firstly and then increased.For certain case,when the equivalent film thickness of oilsupply is approximately equal to the minimum film thickness of fully flooded lubrication,the highest temperature rise in the contact area is relatively minimal.
