How do you find the needed gears and final gear ratio of a two stage transmission that will generate a speed of 15fps? The wheel diameter is 6 inches. And the motor has a RPM of 6380 and a torque of 4.69.
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)
