PLANET TRANSMISSION Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: planet transmission has tree coaxial races and ball satellites. Working ways having a radius roundings at sites of intersection of screw ways are arranged on the inner and outer races. The intermediate race has longitudinal grooves wherein the ball satellites are received. The satellites interact with the working screw ways. The longitudinal grooves made over the generatrix of the intermediate race are arranges in the axial direction with an angle shifting and enclose the whole circumference. EFFECT: improved design. 5 dwg
