Try using the spline tool for the path of a single link. A second spline
would be used for the rotation. Then using the clamp to wrap the spline T
value based on the number of links needed and the spaceing. One you find the
difference between each link this is added to the T value. It should place a
link all around the spline which would be in the shape of the normal path of
a chain around the gears.

I hope this makes sence.
