摘要：
A thermal starved elastohydrodynamic lubrication (EHL) model is proposed to study effect of starved lubrication on the contact performance of a spur gear pair. Minimum film thickness, maximum temperature, and the coefficient of friction at interfaces are predicted from the gear tip to the root. Three characteristic meshing locations along the line of action are chosen to represent different slide-to-roll ratios the gear pair endures. The inlet oil supply is utilized to represent the degree of the starvation. Effect of the load and speed are studied under the starved lubrication conditions, which is compared to the results of the fully flooded cases. (C) 2015 Elsevier Ltd. All rights reserved.
