BACKLASH-FREE PLANETARY-LANTERN GEAR Russian patent published in 2016 - IPC F16H1/32 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, specifically to machine drives. Planetary lantern reducer consists of a high-speed stage, wherein central wheel with half herringbone gears 2 and 3 having outer involute teeth is engaged with satellites 5 with half herringbone gears 4 and 5, cantilever-fixed on eccentric shaft 6, rotating in bearings 12 housed in cage 8 lantern transmission satellites 9 cycloid tooth profile mounted by bearings 10 on respective cams of shaft, and interacting with the bobbin 11 fixed to inner surface of housing 1. Satellites of high-speed stage 5 are fixed on eccentric shafts by seats with interference generated by movement of said satellites by nuts 17 along conical ends of eccentric shafts.

EFFECT: simplified assembly of reducer and reduction gear backlash on output link.
