PLANETARY GEAR Russian patent published in 2014 - IPC F16H1/32 F16H57/08 

FIELD: machine building.

SUBSTANCE: invention relates to machine building industry, in particular, to mechanical transmissions. planetary gear comprises driving eccentric pinion carrier (1), two satellites with external teeth and holes on the rims (2), stationary central gear wheel (3) with inner teeth, driven shaft (4), rigidly linked with driven shaft using strainers (7) jaws (5, 6) with holes and rollers (8) installed freely in holed of jaws (5, 6) and rims of satellites (2). The rollers (8) of one satellite (2) are made with a circular groove in the location of another satellite (2), with the length corresponding to cumulative width of satellites (2) and two jaws (5), (6). The diameter of the rollers (8) in the place of groove is less than the diameter of holes in the rim of the satellite (2) at least by three inter-axial distances of transmission. One half of the rollers (8) transmits the moment from one satellite (2) to jaws (5, 6) and driven shaft (4). The second half of rollers (8) transmits the moment from another satellite (2). The decrease of the axial size of transmission is achieved at the expense of the length of the rollers (8) equal to cumulative length of satellites (2) and two jaws (5), (6), and by arranging of rollers in one row, that does not require to install between satellites (2) an additional support jaw.

EFFECT: perfected design.
