PLANETARY GEAR BOX 26R10 Russian patent published in 2017 - IPC F16H57/33 F16H3/44 F16H37/04 

FIELD: machine engineering.

SUBSTANCE: planetary gearbox comprises a housing defined it with two simple three-tier planetary mechanisms. The housing supports mounted shafts of the sun gears of planetary mechanisms, these shafts with gear rings on the ends freely set the input and output shafts of the carrier pipe with toothed crowns. On tubular shafts arranged coaxial shafts housings epicyclic wheels and gear teeth. On the inner wall of the ring gears with the gearshift clutches stop carrier or epicyclic wheel are fixed. At the output of the shaft of the sun gear of the first planetary mechanism, the drive gear of the matching gearbox with a gear ring and a two-position clutch at the input of the gear and with a gear ring at the output of the gear near the gear ring of the shaft of the sun gear are freely installed. The driven gear matching gear with a ring gear fixed to the tubular shaft freely mounted on the shaft of the sun gear of the second planetary gear about the gear ring on the inlet of the shaft adjacent to the toothing outer wall of the housing and equipped with bilateral switching clutch, the outlet of the tubular shaft gear fixed gear crown with a two-stage switching clutch.

EFFECT: reduced weight and metal planetary gearbox.
