PLANETARY REDUCTION GEAR WITH DOUBLE SATELLITES Russian patent published in 2020 - IPC F16H37/08 F16H3/74 

FIELD: machine building.

SUBSTANCE: planetary reduction gear reducer with double satellites comprises input shaft with gear, not less than three kinematically connected to input shaft of peripheral shafts, axes of which are parallel to axis of central output shaft and equidistant from it, and bearing cylindrical gears, which form external engagement with cylindrical wheel, having common hub with one of central differential wheels and internal engagement with combined internal engagement wheel and carrier rigidly connected with central output shaft. Satellites of differential have two rims, one of which enters external engagement with one of central differential wheels, and another one – into internal gearing with combined internal gearing wheel, at that differential is located inside combined wheel.

EFFECT: reduction of overall dimensions and increase of reduction gear life.
