I have looked everywhere to try and find how to calculate the distance a rack will move.
I have a mechanism where every revolution of the pinion, the rack will move one direction, then it will move back in the opposite direction. So I assume the ratio will be 2:1, every one rev the pinion does, the rack will move forward, then return. I can find loads of material on gear ratios etc, but nothing on how to work out the distance a rack will move depending on the wheel diameter and No. of teeth.
Or do I just use standard gear ratio calculations? Such as this: http://www.schsm.org/html/gear_ratio_calculations.html
