Overload Evaluation of Rotorcraft Tail Rotor Drive Spiral Bevel Gears

This paper details an effort conducted to evaluate the effects of short to moderate duration overloads on the spiral bevel gears of the UH-60 helicopter tail rotor drive train. The focus of the effort was on the UH-60 intermediate gearbox (IGB). An initial analytical assessment of the effect of loads above the endurance limit was conducted using an American Gear Manufacturers Association (AGMA) based approach.
