PLANETARY REDUCTION GEAR WITH INTERNAL GEARING Russian patent published in 2025 - IPC F16H1/32 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to machine building. Planetary reduction gear with internal gearing contains three in-series located internal gearing planetary wheels, each of which is fitted on the high-speed shafts eccentrics, cams on each shaft are phase-shifted relative to each other by equal angles of 120 degrees and all three wheels of internal engagement are engaged with same gear of external engagement. All three internal engagement wheels are fitted on eccentrics of two diametrically opposite shafts. Number of teeth of each planetary wheel is by three teeth more than number of teeth of gear of external gearing.

EFFECT: reduced requirements to accuracy of parts manufacturing and reduction of one of transverse dimensions.
