PLANETARY GEAR Russian patent published in 2016 - IPC F16H1/32 

FIELD: machine building.

SUBSTANCE: invention relates to gear mechanical transmissions. Planetary gear includes eccentric carrier (1), satellites with external teeth (2), fixed central wheel with internal teeth (3), swivel casters with spherical surfaces (4), pins (5) installed in the cheek of output shaft (6). Swivel casters (4) are made hollow, and pins (5) are as cantilever beams with spherical surfaces located inside hollow swivel casters (4) and in contact with their inner cylindrical surfaces. Hollow swivel casters (4) are arranged simultaneously in apertures of satellites (2) and on pins (5) with minimum clearance letting swivel casters (4) to self-install during the motion transmission from satellites (2) through pins (5) to output shaft (6).

EFFECT: decreased axial dimension of planetary gear is achieved.
