Three fully formulated SAE 75W-90 axle lubricants are examined. The effect of inlet shear heating (ISH) and starvation is accounted for in the developed friction model. The film thickness and the predicted friction
are compared with experimental measurements
obtained through optical interferometry and use of a mini traction machine. The results indicate the significant contribution
of ISH and starvation on both the film thickness and coefficient of friction. A strong interaction between those two phenomena is also demonstrated, along with
their individual and combined contribution on the EHD friction.
