Gear Study Answered

The last Friday of the month is a build day around Instructables HQ. I've been meaning to create some art involving gears of different pitches, so I took part of my build day to do a study in gears. These are two laser-cut acrylic gears I made on our Epilog 36EXT that are half 10 in pitch diameter and half 20 in pitch diameter. I advanced the 20 pitch side about one-half of a pitch.



The gears were designed in OMAX Layout, which just happens to have a nice gear profile generator. I'm hopeful about putting together a set that gradually change pitch diameter.

There's a bit of slop between the gears, and I'm taking advantage of it (at least in this set) to keep the teeth from colliding at the transition. They only rotate freely in one direction; in the other they bind.

Looks like you're gearing up for something, Eric...

What was that, feed a cog and starve a lever, or somethin like that?

I don know. Everytime I try to start my mental machinery, the gears become sticky and gooey, really bogs down the works, you know?

You need some chicken grease in the works, Grandma probably had the best recipe for it. Apply sparingly or liberally depending on your politics.

Well, unfortunately even that was snot good enough to relieve the sinus pressure / problems. But, I am starting to feel things loosen up now that the antibiotics are working. They gave ma a bit of leverage in this case.

I can see where similar gears could be used in a one half rotation / then rock backwards configuration to mesh a gear pitch of one type to another, but what else would this be useful for? It (maybe) changes the strength a bit but I don't believe the speed of rotation would be effected.

That's pretty interesting. I'm working on a project right now that involves cutting my own gears from brass.
