Gears, Velocity Ratios and Mechanical Advantage

• You can calculate the gear ratio by using the number of teeth of the "driving gear" (a.k.a. the inputgear) divided by the number of teeth of the "driven gear" (a.k.a. the outputgear). • We gear up when we increase velocity and decrease torque. Ratio: 3:1 • We gear down when we increase torque and reduce velocity.

How to Calculate Speed Ratio | Sciencing

Jan 28, 2019· If you know the speed ration and the speed input, you can calculate the speed output using the formula output speed = input speed ÷ speed ratio. For example, if you have a speed ratio of 3, and the input gear revolves at 180 rpm, work out 180 ÷ 3 = 60. The output speed is 60 rpm. You can reverse this formula to work out speed input if you know the speed output and the speed ratio. .
