PLANETARY REDUCTION GEAR Russian patent published in 2020 - IPC F16H1/32 F16H1/46 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Planetary reduction gear comprises input shaft, first satellite with first and second gears, first fixed housing, output shaft, second fixed housing, whirls placed in housings and output shaft, the second satellite with the first and the second gears, on the input shaft there are two eccentrics, besides, one of them is turned relative to the other one by half of revolution. Second housing and second satellite are arranged centrally symmetrically, respectively, to first housing and first satellite relative to point located between two eccentrics and on axis of rotation of input shaft, on side surface of each eccentric there is a support with which one of satellites interacts, teeth of pinions of pinions are made in the form of cycloid, the first gear of the first satellite is engaged with the cogs in the first fixed housing, the first gear of the second satellite is engaged with the pins in the second housing, the second gear of each satellite engages with the cogs in the output shaft, first gears of each satellite are made with equal number of teeth, second gears of each satellite are made with equal number of teeth, housing have same number of whirls, two bearings of the input shaft and two bearings of the output shaft are arranged on both sides of the plane perpendicular to the axis of rotation of the input shaft and lying between the eccentrics.

EFFECT: higher loading capacity of reduction gear.
