Input: blue gear shaft. The number of teeth of the two blue gears is 32 although their diameters are different.
Output: yellow and orange shafts. The number of teeth of the two gears is 16 although their diameters are different. They rotate at the same speed and in the same direction.
Two white bearings can be rotated thanks to the pink worms. So the bearing position of the output shaft is adjustable.
See a simpler case when the output shafts rotate at the same speed and in opposite directions:
