Output: the blue disk.

The yellow bearing house of the orange roller can rotate around a fixed bearing.

The inside surface ot the disks is created by a round profile, center of which is on the axis of the yellow bearing house. This axis does not intersect the disk axes. There is a offset.

The roller contacts with the disks at its outside edges.

Contact pressure is created by two brown springs.

Turn the yellow shaft to change contact position for various output velocities.
