PLANETARY REDUCTION GEAR Russian patent published in 2019 - IPC F16H1/32 F16H1/46 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Planetary reduction gear comprises input shaft arranged on bearings, planet pinion, in which two fixed relative to each other gears have different number of teeth, housing, output shaft arranged on bearings. On the input shaft the eccentric is located, on which the planet pinion is located, gears teeth are made in the form of cycloid, in the first fixed housing and the output shaft there are pins, the first gear of the planet pinion is engaged with the first solid casing pins, the second planet pinion gear is engaged with the output shaft baffles, in addition, there is a third gear fixed relative to the first two, the second fixed housing with pins, arranged in a mirror manner respectively, the first gear and the first fixed housing relative to the plane passing through the second gear and perpendicular to the axis of rotation of the input shaft. Number of teeth of the third gear and number of pins of the second fixed housing are equal to number of teeth of the first gear and number of first fixed housing pins, two bearings of the input shaft and two bearings of the output shaft are located on both sides of the specified plane. Planetary reduction gear can be used in cable device for tightening docking mechanism of spacecraft.

EFFECT: higher loading capacity of reduction gear.
