Gear Train : Gear Ratio, Torque and Speed Calculations ...

2021-11-18  Gear Ratio. The Gear ratio is the ratio of the number of teeth of the driven gear and driver gear. It is used to calculate the speed and torque of the output shaft when input and output shafts are connected using a gear train. Input gear where torque is applied is known as driver. Whereas output gear is known as a driven gear .

2008-9-1  With these requirements in mind, let’s look at three possible solutions, one involving a single branch, two-stage helical gear set. A second solution takes the original gear set and splits the two-stage reduction into two branches, and the third calls for using a two-stage planetary or star epicyclic. In this instance, we chose the star.
