why can’t we have gear ratios like 1:300.000

562 views

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?

Probably because there’s only so much force the gear teeth would be able to take before breaking under the force of the torque. But that’s just my guess, I don’t really know.
