Gear ratios and compound gear ratios
To get the reduction ratio for both gears, we want each gear ratio to be about the square root of 12, which is about 3.464. Now 8 * 3.464 is 27.7. So lets try 28 teeth for the intermediate gear. So we can write 8:28:96 or 8:28 and 28:96 We can divide the right side by 4, so we get 8:28 and 7:24.

How to select gear ratio for a gear reducer?
Nov 09, 2018 For instance, to take speed reduction, the amount needed will depend on the type of motor used. That’s because some motors can operate at low speeds (less than 1,000 rpm, for instance) without the need for a gear reducer, while others cannot. For speed reduction the gear ratio is calculated using the equation: G = N MOTOR / N LOAD
