Any mechanical engineer in here?

I just made the cogwheel much smoother...

 

But I know there are some standards for gear dimensions, to make sure they fit together. Like the internal radius should be X fraction of the contact radius (forgot what that one was called)

 

Anyway... if anyone around here have quick links to these kind of things, would be nice. Cogwheels could be nicer, and most likely be drawn faster too, cause we could draw them with a predictable number of lines, instead of drawing a segment for each fraction of circle
