WebCompound Train Example. To obtain the gear ratio, TV = (output rate)/ (input rate), of a compound gear train, an illustrated example is presented in this section. The procedure is to start with the input, and to calculate how the angular velocity propagates through each successive intermeshing pair of gears based upon the number of teeth. WebWhen a gear train has multiple stages, the gear ratio for the overall gearing system is the product of the individual stages. For example, for the gear at left the blue gears are 7 and 21 teeth, while the green gears are 9 and 30 teeth. Thus, the first gear ratio is 7:21 and the second is 9:30. Multiplying the two together gives (7x9):(21x30 ... WebJun 25, 2024 · Gear ratios. The ratio is the number of teeth on the driven gear (ring gear) divided by the number of teeth on the driving gear (pinion gear). For eg, if the driven gear has 36 teeth and the driving gear has 12 teeth, the gear ratio will be 3:1. This also means that for every one driven gear the driving gear will turn 3 times. chor neubau
