PLANET GEAR Russian patent published in 2007 - IPC F16H1/46 

FIELD: mechanical engineering.

SUBSTANCE: planet gear comprises solar pinion (1), satellites (2), bearing ring (6) of satellites, unmovable central wheel (4) with shortened inner teeth, and low-speed central wheel (7) with teeth-cross-pieces. Slider bearings (5) of the low-speed wheel are made of two wheels with inner teeth. The thickness of the slider bearings corresponds to the width of the hollows of teeth-cross-pieces of the low-speed wheel. The bearings are mounted on the low-speed wheel at sites where the wheel teeth-cross-pieces are secured to the rims.

EFFECT: reduced axial sizes.
