Gear ratios and compound gear ratios
Determining compound gear ratios (multiple stages) When 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.
