If you're looking for reliable, primitive gears: look at an old watermill's wooden "crown wheel" and pinion.

That being said, you'd get the same effect with pulleys and belt. Hand carving wooden pulleys or turning them on a simple pole lathe with a sharp or abrasive rock would much easier than making gears.
