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

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Planetary reduction gear comprises high-speed eccentric shaft (1), satellites with radial holes (2), fixed central wheel with inner teeth of circular or cycloidal profile (3), flanges with radial holes (4) and (5), braces (6) connecting flanges (4), (5), and rollers (7) located freely, movably in holes of pinions (2) and flanges (4), (5). Diameter of rollers (7) is less than diameter of holes of satellites (2) and flanges (4) and (5) by value of eccentricity of high-speed eccentric shaft (1). Satellites (2) are made in form of two disc-free disks located at the ends of fixed central wheel (3), and rollers (7) are conjugated with teeth of fixed central wheel (3), profiles of which are outlined along arc of circle, forming internal engagement, wherein number of rollers (7) and corresponding radial holes in satellites (2) and flanges (4), (5) is one or two less than number of teeth of fixed central wheel (3).

EFFECT: reduced cost of planetary gearbox and increased load capacity.
