I think you need a conic shape for the internal gear if you want to tighten up the tolerances on both outer discs. Also, I see a wobble in your future, but this might be a nice way to advance a shaker conveyor for mining or maybe for a crusher/compactor type machine that benefits from loosening up whatever is being processed. Of course, you can always just increase the orbit and shrink the size of the internal gear, add two more, and you've got a planetary gearbox almost made.

The input and output shafts don't (and CAN'T) remain in line with each other as it rotates. It's broken. The principle though might be sound if your internal gear has TWO different profiles, each one matches an external gear. So basically, it might work, but you are only about halfway there.

Could you please make a video where you combine these 3 things together. - Cheers Len

I know of at least two makers of cycloidal tuners (both of whom somehow got patents granted for the basic cycloidal mechanism), so they do work. Easier to get low backlash when a little friction is necessary to hold position. I've been playing with harmonic gear tuners, but machining them on my little CNC is too time consuming to be profitable. I should make a video on them. I tried posting a link to my R&D thread on the OLF, but youtube ate it, and I don't think you can view the photos without creating an account anyway.

Is a gear with oloids possible? I mean, I'm sure someone's already thought of it and scrapped the idea. But the question is what's in the middle? You mentioned friction and roll? Is there a tooth shape that's pretty much the middle? Can't really count a worm gear because its basically a single tooth that stretches the length of the screw. The rounded gears function similar to the geneva drive gear, and of course there's the geneva drive (the cross) But is there a gear tooth geometry that has about the same surface friction or physical action as the lantern and peg gears?

I wonder if these could be used to build a transmission, use clutch packs or dogs to connect it to the output shaft, use it in place of planetary gears. In a automatic transmission for example, or sliding dog's in a manual, but seem the ratios are too deep, a 1gear in a normal transmission, is 6:1 at the lowest, usually 4.25:1 or something. then 3.10:1, then a 2.50:1, as 1.25:1 a 1:1, the . 80:1 overdrive , .70:1, I doubt as low/high as a .50:1, usually in the range of .70:1-to .90:1. Having a untraditional low friction gear set in a transmission would be awesome!

Amazing! It's a harmonic drive without the limiting factors of a harmonic drive, namely, the need for flexible material. I imagine it would be a lot easier to find suitable materials for use in extreme environments, when you don't have to concern yourself with it's elastic properties at those extremes! Amazing. Is any of this patentable? If so, you should, because the potential is massive.

Not trying to discredit all the hard work you're putting into your videos, but but this is not an external cycloid gear. Cycloid is a curve traced by a point on a circle as it rotates, which is why there's some math involved, although it's not too complex. What you made here is a modification of a split ring planetary gear, with a single planet and sun gear replaced by eccentric carrier.
