Well, that simple "Yes" can open a huge can of worms and ruin someone's day.

If you use the belt and associated gear to move something linearly, fine. Fabulously inexpensive, too. Compared to $6 for 20cm of Kelvin track.
BUT
Use the belt in its as-built purpose (non-slip V-belt) and just spin a gear, and you no longer have a rack & pinion.

As an event sup, I'll be looking for one of the following three:
A rack moving linearly, turning a stationary pinion gear
A stationary turning gear moving a rack linearly.
A stationary rack upon which a gear moves linearly down the track
PLUS:
The operation of one of the three above CAUSING the next action/step/whatever.


REMEMBER that it's the SETUP and USE of the component(s) that determines what simple machine is being used.

Thank you for the explanation. I will take a closer look at the system I have.

Yes, please be careful. I didn't properly know the definition of rack and pinion, and I used a chain drive and didn't get points for it at the competition.
