MULTIPLE-ROW PLANETARY GEAR Russian patent published in 2017 - IPC F16H1/48 

FIELD: machine engineering.

SUBSTANCE: multi-row planetary gear contains a sun gear (1), satellites (2), bearings (3), axles of satellites (4), a stationary center wheel (5), a carrier consisting of an output shaft (6) and associated discs (7), (8), (9), which number corresponds to the number of rows of satellites (2). The carrier configured with stepped braces (10) connecting the discs (7), (8), (9) and the output shaft jaw (6). The braces diameter (10) at locations of the rows of satellites (2) is matched according to the width ratio of the sun gear (1) to its diameter thereby the displacement of one carrier disc under load is relative to the other due to deformation of braces (10) and satellite axles (4) and corresponds to the deformation of the sun gear (1) torsion, thereby reducing nonuniformity of load distribution in the gears.

EFFECT: simplified design of the multi-row planetary gear with a mechanism for stabilising load in the gears and increased level of its manufacturability.
