PLANET GEAR WITH PSEUDOPIN GEARING Russian patent published in 2013 - IPC F16H1/32 

FIELD: machine building.

SUBSTANCE: proposed gearing comprises fixed sun gear 1, pinion carrier-cam shaft 2 with two cam shifted through 180 degrees, two plane pinions 3 running bearings 4 on said pinion carrier-cam shaft 2, mechanism of parallel cranks including two flanges 5 engaged by webs 6 and pins 7 extending through holes in plane pinions 3. Flanges 5 are fitted thrust bearings 8 in sun gear 1. Thrust bearings 9 of pinion carrier-cam shaft 2 are fitted ion bores of flanges 5. Active sections of sun gear tooth profiles are circle arcs with misaligned centers of different side of teeth. Conjugated profiles of sun gear teeth 1 are equidistant curves of elongated hypocycloid.

EFFECT: simplified design, higher hardness.
