Lesson
Let's take a look at a compound gear. We will see how it is constructed, and examine the impact it has on the overall gear ratio.
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 the 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) = 63:630, which is 1:10. So the big green gear will make 1 turn for every 10 turns of the small blue gear.
