PLANET BALL GEARING Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: planet ball gearing comprises central bearing disk (1), central output disk (2) and floating disks (8) and (9) interposed between them. Disks (8) and (9) are mounted on the antiphase eccentrics of output shaft (7) through bearings (10) and (11). The surfaces of disks (8) and (9), which face each other, are provided with periodic raceways (12) and (13) which cooperate through the first chain of balls (14). The surfaces of floating disks (8) and (9), which face central disks (1) and (2), are provided with closed periodic raceways (16) and (17). Periodic raceway (16) cooperates with the periodic members made of semispherical hollows (18) made in the surface of bearing central disk (1) through chains of balls (19). Periodic raceway (17) cooperates with periodic members made of semispherical hollows (2) in the surface of output central disk (20) through chains of balls (21).

EFFECT: simplified method of manufacturing.
