  • Gear Tooth Temperature Measurements Gear

    BackgroundExperimental EffortComparison of Experimental vs. AnalyticalConclusionsReferencesIn order to provide extended operation of gears in a “loss of lubricant” situation in high performance gearboxes, special steels have been introduced for aircraft gears. However, further benefits, such as increasing aircraft payload by decreasing the size and capacity of the lubrication system, could be derived if the gearbox were designed to operate at higher temperatures. This design change requires that the fatigue performance of these special steels be characterized at elevated temperatures. In an effort to e
