I’ve recently seen videos on YouTube showing gear ratios like 30 million to 1 when you spin the first gear super fast at 10.000rpm and the last gear spins so slow it would take 300 hours to spin once for example. Searching for the opposite doesn’t give any result, the highest I found was 1:625.
Why is that we can have millions:1 gear ratios but not 1:millions?
In: Engineering
Torque and power. You need apply very little torque on the reduction gear since you’re trading a lot of initial velocity to get a lot of torque at the end. But going the other way around you’d have to apply a huge amount of torque on the first gear just to move the last one.
