PLANETARY PRECESSIONAL GEAR Russian patent published in 2020 - IPC F16H1/32 

FIELD: transmission.

SUBSTANCE: invention relates to planetary gearing. Planetary precession gear includes crank (1) connected to input shaft, main double gear with involute barrel-like teeth and inner cylindrical surface in end part (2), additional two-seat satellite with involute barrel-like teeth and spherical surface in end part (3), spherical bearing of main satellite (4), fixed involute central wheel (5), output shaft (6), angular couplings (7), bearing of input shaft (8), output shaft bearing (9), housing (10) and cover (11). Main double gear (2) is put on rollers of angular coupling (7) and by means of spherical bearing (4) – on the input shaft with bell crank (1) and is engaged with the fixed central wheel (5). Additional double gear (3) is put on rollers of angular coupling (7) and engages with fixed central wheel (5), its spherical surface is conjugated with inner cylindrical surface of main double gear (2).

EFFECT: higher level of manufacturability of gear.
