PLANETARY GEAR Russian patent published in 2010 - IPC F16H1/48 

FIELD: machine building.

SUBSTANCE: planetary gear consists of central gears (1, 2), of carrier (4), of satellites (3) installed on pins (5) of carrier by means of bearings (6). Bearings (6) are positioned concentrically with the pins of the carrier. External diametre of the bearing is less, than internal diametre of the satellite at a value of doubled eccentricity. Pins axes are offset relative to the satellites at the value of eccentricity. Difference in diametres of the external ring of bearing (6) and internal diametre of satellite (3) in the value of eccentricity facilitates satellite to perform both rolling motions relative to surface of contact with external ring of bearing (6) and generating motion relative to whole surface of bearing (6) at interaction of elements of the planetary gear.

EFFECT: due to rotating motion of satellite relative to bearing there is facilitated uniform wear of surface for generating motion of satellite, also there is increased uniformity of wear and service life of planetary gear.
