PLANETARY REDUCTION GEAR WITH TWO COAXIAL OUTPUT SHAFTS OF OPPOSITE ROTATION Russian patent published in 2020 - IPC F16H48/06 B64C27/12 

FIELD: machine building.

SUBSTANCE: invention relates to planetary reduction gearboxes. Planetary reduction gear includes input shaft, rotationally fixed in reduction gear housing, having circular eccentric part, axis of which is spaced from inlet shaft rotation axis by eccentricity value, satellite with first and second toothed rims having different number of teeth, rotationally fixed on said circular eccentric part, around its axis, first and second central gears of internal engagement, engaged each, with one of gear rims of satellite, forming two pairs of wheels of internal gearing with same interaxle distance, equal to the eccentric part eccentric part, the first internal engagement wheel is fixedly fixed in the gearbox housing, and the second one is connected to the first output shaft and together with it is rotationally fixed in the gear housing, coaxially with input shaft. Satellite includes the third toothed rim and the third central gear of internal gear engaged with it with interaxle distance, which is equal to eccentricity of eccentric part, connected to the second output shaft and together with it rotatably fixed in the reduction gear housing, coaxially with the input shaft.

EFFECT: higher loading capacity of planetary reduction gear.
