PLANETARY GEAR BOX 5R2 Russian patent published in 2017 - IPC F16H37/04 F16H3/44 

FIELD: machine engineering.

SUBSTANCE: planetary gearbox containing a body, a simple three-link planetary gear consisting of a sun gear, an epicyclic wheel and a carrier with satellites that are engaged with the sun gear and an epicyclic wheel, the carrier and the body of the epicyclic wheel have shafts with toothed rims and an epicyclic wheel stop coupling, Is characterized in that the input shaft has a three-position gear ring on which the shift clutch is mounted, the shaft of the sun gear with serrated crowns at the ends is mounted in a support Gear ring of the driving gear and in the support of the rear wall of the body of the unit with a gear ring, the carrier is fixed to the input and output tubular shafts with toothed rims, the body of the epicyclic wheel is fixed to the input and output coaxial shafts with gear rims, on the inner walls of the body of the unit next to the gear rims of the input shafts are fixed toothed crowns with couplers for stopping the carrier or an epicyclic wheel; next to the gear rims of the output shafts there is a leading tubular shaft with a gear ring at the shaft inlet and a pinion gear with a ring gear at the outlet This shaft is next to the gear ring of the shaft of the sun gear, on which the clutch is located.

EFFECT: reduced weight and metal planetary gearbox.
