"Proper" gears are designed with an involute profile so that the point of contact between the teeth does not change as the gears rotate. The gears we use have a flat tooth profile for reasons of economics. This means that the teeth must slide across each other as they rotate. Bigger teeth have to slide more relative to each other so are theoretically less efficient. On the other hand a smaller tooth will distort more if loading is very high making the samll teeth less efficient. I think you are right about the main factor being the ability to fine tune ratios though.
I did realize that, was just trying to save the boring tech for us engineers
I figured I would leave out base circle, pitch diamenter, etc out of the equation. I had a chat with a friend that is a machinist and to make our gears the right way is to expensive for the gain.
BTW I'm 5 weeks and 7 3 hour exams off being a mechanical engineer.
Congrats Dude!!!!! Finished my 8 years of night school in 92.
