• Several gear materials, gear processes and gear lubricants were evaluated for surface fatigue life in the NASA spur gear fatigue test rig during the last several years. Some of these materials include VIM-VAR AISI 9310, EX-53, CBS-1000M, CBS-600, VASCO-X2, M5O-Nil, VASCO Matrix II, VASCO Max 350, and Nitralloy N. Some of the various processes include shot peening at different intensities. Several aircraft gear lubricants with different viscosity's and additives were evaluated for their effect on surface fatigue of standard spur gears. These materials and lubricants were evaluated for possible use in advanced aircraft gear applications. The fatigue life of the gear materials and lubricants were compared with the life of the standard AISI 9310 gear material and the base lubricant. Surface fatigue tests were conducted at a lubricant inlet temperature of 49℃, a lubricant outlet temperature of 77℃, a maximum Hertz stress of 1.71 GPa and a speed of 10000rpm.
