PLANETARY GEAR Russian patent published in 2013 - IPC F16H1/32 

FIELD: machine building.

SUBSTANCE: planetary gear with inner engagement comprises an annular ring (1), rotary flanges (3), a carrier-eccentric shaft (4), installed in bearing supports (5) of flanges (3), satellites (6), installed with support bearings (8) on the carrier-eccentric shaft (4). Two wheels with inner teeth (7) and wheels with outer teeth (9), which are engaged with wheels (7) and are joined coaxially and rigidly with flanges (2) by means of bolts-links (10), stretching via holes (11) of satellites. Matching of non-coaxial rotary movements of satellites and flanges is carried out with the help of geared wheels (7, 9) with identical teeth number.

EFFECT: invention makes it possible to increase reliability and durability of planetary gears due to reduction of unevenness of forces acting at parts of a gear.
