PLANET BALL TRANSMITTING UNIT Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: unit comprises tree disks (1), (2), and (3) which are arranged in series along the single axis and co-operate with each other through a chain of balls (6). Each of the disks can be driving, driven, and bearing links. Intermediate disk (1) is a floating washer freely mounted on the eccentric for the interaction with balls (6) by its cylindrical side. The mating sides of disks (2) and (3) are provided with closed curved way (5) and interrupted radial grooves (4) uniformly spaced over periphery. The depth of the closed way is greater than the radius of ball (6). The cross-pieces of radial grooves (4) are provided with axial projections (9) in the zone of movement of the centers of balls (6). The surfaces of projections (9) are inscribed in the surface of closed way (4) with a spaced relation for providing mutual rotation of the disks.

EFFECT: enhanced reliability.
