PLANETARY GEAR WITH ROLL-ON INTERMEDIATE BODIES Russian patent published in 2017 - IPC F16H1/36 F16H25/06 

FIELD: mechanical engineering.

SUBSTANCE: planetary gear with roll-on intermediate bodies comprises two sun wheels, one of which is associated with the housing, the carrier, the satellite and two groups of intermediate roll-on bodies, which are in contact with the surfaces of the teeth formed on mutually facing end surfaces of the sun and the satellite wheels. Each group of the intermediate roll-on bodies is positioned separately and combined with a separator, which is a thin-walled disc with holes for the balls and mounted between two mutually facing end surfaces of the sun wheel and the satellite. To except the load at the separator, the current bunch of engaging points of each pair of links, compiled by the sun wheel, satellite and separator with intermediate bodies, balls, non-contingent self-aligning "parasitic" wheel, aligned and mating teeth surfaces with sun wheels and satellite are the surface, contacting the tubular surfaces, which are formed by the spherical surface of the intermediate roll-on bodies in their desired relative motion.

EFFECT: increase of reliability of the planetary gear.
