PLANETARY GEAR Russian patent published in 2024 - IPC F16H1/28 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Planetary gearing comprises housing, input shaft, central gears with external and internal gearing, carrier and satellites. Two input central sun wheels with external gearing are installed and rigidly fixed on the input shaft. In the housing coaxially with the sun wheels on bearings with the possibility of rotation around the transmission axis there is a central crown wheel with two toothed rims with internal engagement, wherein the first crown wheel rim is kinematically connected to the first input sun wheel by means of additionally introduced intermediate gears with external engagement, axes of which are rigidly fixed on the housing, and the second crown wheel rim is connected to the second input sun wheel by means of satellites installed on the carrier, which is rigidly connected to the output shaft of the transmission. Gear ratio of the transmission is determined by a combination of numbers of teeth of the first crown wheel rim, the first sun wheel, the second crown wheel rim and the second sun wheel.

EFFECT: higher gear ratio of the transmission at maintaining low weight and dimensions.
