I have a basic understanding of how to calculate gear rpm, but have no idea as to how one could figure out what size and number of teeth you would need if you want to give X turn to the drive gear to get a rack to slide Y inchs. Obviously I would want to contain the entire assembly in the the smallest place possible. I doubt I explained very well so here is a diagram of what I would like to do, excuse the not so technical drawing:(adsbygoogle = window.adsbygoogle || []).push({});

From what I've read I want 4x as many teeth (as the second gear) on my drive so 1/4 turn gives a full rotation on my second gear, my third will be the same amount of teeth as gear 2, now I just need to figure out how many teeth on the final gear that actually moves the final piece.

PS: I hope this is in the correct section
