PLANETARY REDUCTION GEAR WITH INTERMEDIATE PINION Russian patent published in 2021 - IPC F16H1/28 

FIELD: machine building.

SUBSTANCE: invention relates to the field of machine building. Planetary gear with intermediate pinion comprises a housing, inside of which two central wheels are located coaxially: fixed, rigidly connected to housing, and movable, rigidly connected with low-speed shaft, on inner surfaces of which there are teeth with different number, as well as carrier rigidly connected with high-speed shaft. Central wheels have kinematic connection with additionally introduced intermediate pinion, which is a double gear with external teeth and inner smooth surface located inside central wheels, and carrier, located inside intermediate pinion, is made in form of eccentric, and comprises three roller or roller bearings, one of which, located in the eccentric vertex, is the leading satellite and provides kinematic connection of the intermediate satellite with the central wheels, and two others - fixation of centre-to-centre distance between them, wherein carrier rolls bearings along inner surface of intermediate satellite during rotation of high-speed shaft.

EFFECT: decreased overall dimensions of reduction gearbox.
