Gear simulator problem

Here's a rough example of how to set this up.

Note how the outer ring has a slit so it can be identified as a single shape with an inside and outside.

Also, this is a very hastily drawn gear tooth profile with massive backlash!

If you have just 2 smooth circles (like in the first row of images in your link) they will slide against each other instead of turning, but I think you could directly simulate things like in the second row without adding teeth.

Also - there was a very nice post by John Baez on these shapes:
