CARRIER FOR PLANETARY REDUCTION GEAR Russian patent published in 2007 - IPC F16H57/08 

FIELD: transport engineering; fixed-ratio planetary gear transmissions.

SUBSTANCE: proposed carrier has drive shaft, right-hand and left-hand cheeks, central plate arranged between cheeks, main axle secured in coaxial holes of cheeks and central plate. Planet pinions for two planetary gear trains are installed on main axle on bearings. Right-hand cheek is rigidly connected with central plate. Left-hand cheek is coupled with central plate by bridges. Central plate is connected with drive shaft. Intermediate axle is installed in coaxial holes of cheeks and central plate. Planet pinion of one planetary gear train is arranged on main axle on section between left-hand cheek and central plate. Planet pinion of other planetary gear train is arranged on main axle on section between right-hand cheek and central plate, being engaged with planet pinion installed on intermediate axle on the same section.

EFFECT: increased body rigidity of carrier, changed design of carrier to form planetary gear trains with negative or positive gear ratio.
