Opposite Directions

Pulleys and gears can change the direction of motion. In a gear train, several gears contact each other. Each gear moves in the opposite direction of its neighbours.

Imagine a machine that uses gears like the ones above. But there is a problem—the two gears need to move in the same direction. How could you do that?

This problem is not difficult to solve. Simply insert a gear in the middle.

You can connect two pulleys with a belt or chain. This makes a drive system. Both pulleys will move in the same direction.

If the belt is crossed between two pulleys, the pulleys will move in opposite directions.
