Research abstract
The Army's Rotorcraft Force Modernization Fleet requires a substantial increase in main gearbox power density, with minimal impact on the gearbox interface. Instead of increasing gearbox size and transmission weight, this project seeks to accommodate the higher power density requirements through designed material processing techniques, integrating several state-of-the-art manufacturing processes to specifically improve the gear material contact and bending fatigue strengths. In Phase I, a novel heat treating method called "Intensive Quenching", as well as superfinishing will be investigated to determine the feasibility of improving the bending fatigue life of the Pyrowear 53 steel by at least 25% over conventional processing.
