DISK PLANETARY VARIATOR Russian patent published in 2010 - IPC F16H15/50 

FIELD: machine building.

SUBSTANCE: disk planetary variator consists of at least one planetary row and includes external and internal central friction disks (3) and (4) enveloping conic satellites (4) on both sides. One group of central friction disks (8) or (14) is made with external circular bands (5) and (20) and toroid convex rolling paths (7) on them set on disks (3) and (14) in zone of contact with satellites (4). Stops (6) limit axial displacement of disks in the direction of expanding from the satellites.

EFFECT: increased wear resistance of friction elements of variator and increased operation resource of it.
