FIELD: machine building.
SUBSTANCE: invention relates to transmissions with spurs conical gear wheels. Round conical gear with same width of rims for pinion and gear wheel and common generatrix cones of pinion and gear wheel, respectively, external crown gears with radial teeth and outer rim gear wheel with teeth made by rolling of gear with teeth. Sizes of teeth of inner rims of gear teeth and inner crowns of gear wheel teeth are smaller than outer rims of gears and outer rims of gear wheel for value of proportionality factor K, which is calculated by formula: K=1-B/L, where B is width of pinion (gear) toothed rim; L is generatrix, common for cones of pinion and gear wheel.
EFFECT: in radial conical gear with internal engagement with difference of teeth per unit of transmitted torque simultaneously is distributed between multiple teeth to produce high efficiency with high gear ratio at reduced dimensions of mechanisms.
