PLANETARY-COG REDUCTION GEAR Russian patent published in 2007 - IPC F16H1/32 

FIELD: mechanical engineering; drives.

SUBSTANCE: proposed planetary-cog reduction gear has housing 1, teeth-rollers 8 arranged in cavities of housing 1 and forming together with diametric bridges-tops connecting said cavities, internal profile of engagement, turnable unit with flanges 3, 4 connected by bridges, central eccentric shaft 6 with opposite planet pinions 7. Planet pinions engage with cylindrical surfaces of their radial holes with pins 11 providing transmission of torque from planet pinions to flanges. Support bearings 2 of turnable unit of reduction gear are located from diametric bridges-tops connecting cavities for teeth-rollers.

EFFECT: provision of high accuracy of centering of all members of reduction gear.
