PLANETARY GEAR WITHOUT CARRIER Russian patent published in 2012 - IPC F16H1/36 

FIELD: machine building.

SUBSTANCE: planetary gear without carrier includes drive friction central wheel (1) with internal working surface, driven (2) and support (3) central gear wheels with inner teeth. Two main toothed satellite gears (4) are in internal engagement with driven and central support wheels. Two additional satellite gears (5), which have no teeth, are in friction interconnection with drive central wheel and main satellite gears equipped with the corresponding raceways. Driven central wheel (2) is provided with two rims located at some distance from each other in axial direction. Support and drive central wheels are located between them. Toothed rims of driven wheel are fixed on discs (6) with possibility of adjusting the angular position.

EFFECT: invention allows simplifying the design, improving manufacturability and enlarging layout capabilities of the device.
