To determine the ratio of which two meshed gears will move relative to each other, divide the number of teeth on the driven gear by the number of teeth on the drive gear. This is called the gear ratio. If a driven gear with 24 teeth is meshed with a drive gear with 48 teeth, there is a 1:2 gear ratio. Thank you for the fantastic gears tutorial. This helps so much in designing projects. You are correct in assuming that not everyone has this knowledge/training and this explains it better than other, non-lego specific gear tutorials. One note about the gear ratio calculator. I think the display of the resulting gear ratio has the values swapped.
