Use a path deform as was already suggested. Then, under track view, apply a float expression modifier to the Percent Along Path attribute of the path deform. Assign a variable (call it gearrot) to the rotation of the gear on the correct axis. Make the controller equal to ((gearrot/360) * (diameter of gear * pi) * 100)/(length of path)...
What this is saying is:
Take the proportion of the angle spun to find out how far the gear has rotated (% * circumference), and then compare that to the length of the path.
Good Luck!
