Input: yellow sprocket.
The two sprockets have the same tooth number.
The travel length L of the pink rod is equal to the center distance A of the sprockets plus the sprocket diameter D.
L can be very large by increasing A while keeping the height and width of the structure the same.
The speed of the pink rod is constant.
