BALL TRANSMITTING UNIT OF VARIATOR Russian patent published in 2007 - IPC F16H25/06 

FIELD: mechanical engineering.

SUBSTANCE: ball transmitting unit comprises disk rotation members arranged in series and provided with periodic ways (4), (5) and (7) and (8) in the sides that face each other. The ways define pairs of ways that engage each other by means of chains of balls (6) and (9). Two end disks (1) (3) are axially aligned. Intermediate disk (2) is set on eccentric (13) for permitting rotation. The eccentric passes through the unit of shaft (12). Additional embracing bushing (15) is mounted coaxially to the end disks for permitting rotation. The inner side of embracing bushing (15) near intermediate disk (2) is provided with eccentric section (19). Intermediate disk (2) is fit in the eccentric section in the bearing. The eccentricities of the eccentric section of embracing bushing (15) and eccentric shaft (12) are the same and unidirectional.

EFFECT: expanded functional capabilities.
