  • Transmission system with increased power density
    Publication number: 20050193852
    Abstract: A transmission provides for the application of higher design allowables in bending, pitting, and scoring, as enabled by surface-engineering (SE) processes such as isotropic superfinishing and Me-DLC coating to effect increases in the power density of transmission systems.
