    Patent number: 4280376
    Abstract: A single-stage high-ratio compound planetary gear system has gears configured for optimal tooth profile contact to minimize Hertzian stresses under relatively high contact loads characteristic of high-ratio gearing. Criteria is established for determining the optimal line of action required to attain a substantially constant relative radius of curvature between the teeth of a mating set and optimal tooth geometry for maximal contact between mating teeth.
