The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).May 9, 2019
How do you calculate the number of gears in your teeth?
To calculate the gear ratio: Divide the number of driven gear teeth by the number of drive gear teeth. In our example, it's 28/21 or 4 : 3. This gear ratio shows that the smaller driver gear must turn 1,3 times to get the larger driven gear to make one complete turn.Jan 29, 2020

How are gears measured?
Diameter of the gear, measured from the tops of the teeth. Diameter of the gear, measured at the base of the tooth. The distance from the top of the tooth to the root; it is equal to addendum plus dedendum or to working depth plus clearance.
