The gear movement is transmitted from the driving eze to the conduct by the gears sticked to those ezes. Both spinning in contrary ways. You can get a higher velocity using little gears, like that you make the gear spin more and more faster. If you want a lower velocity you must put bigger gears, they make spin slower because they have to move more volume. To keep the same velocity  you must have equal gears, the same size. If we split the driven wheel number of teeth between the driving wheel we get the relationship transmission. Multiplying the relationship transmission for the driving wheel velocity we get the  driven wheel velocity
