HYDRO-MECHANICAL TRANSMISSION Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: hydro-mechanical transmission has hydraulic motor with inclined disk mounted within a case and planet transmission. The last is made of satellites provided on axles of a carrier and gear wheels. The inclined disk of the hydraulic motor has conical gear rim. Each of the gear wheels is conical and provided with two gear rims: outer rim has grater diameter and inner one has smaller diameter. The grater diameters of the rims of the conical gear wheel are differ from each other. Dividing cones of the rims at least of one conical gear wheel are not in coincidence. Outer rim of each conical gear wheel engages with conical gear rim of the inclined disk of the hydraulic motor. Inner rim of each conical gear wheel engages with satellites. EFFECT: enhanced reliability. 1 dwg
