PLANETARY GEAR Russian patent published in 2010 - IPC F16H1/28 

FIELD: machine building.

SUBSTANCE: planetary gear includes housing (1), inlet shaft (2) with eccentricity (3), dual satellite (4), two central gear wheels (5, 6) with inner teeth the numbers of teeth of which differ by one. Central wheel (5) is rigidly attached to housing, the second one (6) is installed with possibility of rotation about axis. Outlet shaft (7) is rigidly connected to central gear wheel (6) with inner teeth. Gear has at least one additional double satellite arranged with possibility of rotation on axis on eccentricity (3) and made in the form of two rigidly connected rims interacting with appropriate inner teeth of central wheels (5, 6). Profiles of teeth of rims of additional satellite are made with an offset in circumferential direction relative to each other. Axes of dual satellites installed on eccentricity (3) are offset relative to each other in circumferential direction.

EFFECT: increasing carrying capacity of gear.
