For future iterations: such high precision circular patterns should be made by indexing the workpiece with dividing head while keeping mill XY locked.

[@bpark10001]

There is another type of cycloidal reduction box you can make that is easier to get backlash-free & easier to fabricate because all the critical machining is groove into planer disk surface. The engagement is axial, not radial. The "rollers" are ball bearings acting between 2 grooved disks. Because of the axial arrangement, backlash can be taken up to compensate for wear or fabrication. 2 facing disks have cycloidal track machined into them: one hypocycloidal, the other epicycloidal. Ball bearings roll between them, held under axial compression. 2 stacked assemblies are used to remove the orbital motion & the difference between the 2 ratios permits large ratios with low lobe counts. A central crank forces orbital motion (same as for drive you have).

[@Nedw]

Do you have a link or keywords to find out more about that design of cycloidal reduction box?

[@bpark10001]

@@Nedw Web search gets nothing (I tried "AXIAL cycloidal gearbox). The search latches on "cycloidal" & ignores "axial". I found about this in old optical catalog (for fine motion of optics without backlash). The benefit of this scheme is the ease of making if you have manual lathe & CNC milling machine. All of the "non-circular" elements are machined on a plane surface (simple cycloidal groove that ball bearings roll in). Calculating the CNC files is simple. It is the superposition of 2 circular motions: one is once around, & the other is multiple times around. One plate has path where the 2 rotations are the same direction (makes cycloid) & the other opposite rotations (makes hypocycloid). The (larger) radius of the once-around rotation & the (smaller) radius of the multiple-times around rotations are the same on the 2 mating surfaces. You need 3 plates (2 surfece-sets) total. The center plate is forced to orbit by eccentric. The ratio between plate 1 & plate 2 is different than that between 2 & 3 & in the opposite direction. For example, if ratio 1 is 15:1 & ratio 2 is 16:1 (reversed), the total ratio of 240:1. I do have CAD files of one I made experimentally. If you have place where I can send them, I offer them for you to look at.

[@RobCalhounPGH]

Ironically, when I saw the thumbnail, I thought it was using ball bearings instead of rollers.

[@Losermachine35]

Coolant is your friend, you can use a spray bottle. Or brush with oil. A few things, this type of drive system is going to be loud compared to constantly meshed spiral cut gears. Also the lash in the gears is there for a reason, as the parts are in use they heat up and expand. Having them too tight will make it very tight and create wear. Also the gap keeps oil flinging in between the teeth. The teeth are also hardened so i have not finished your video yet but i dont see any plans for heat treatment.

[@Losermachine35]

Another thing, you have no vent, this will create pressure as it warms up and cools, you need a vent in and gearcase or transmission or the seals will blow out.

I hope this actually works, as I have not personally used this technique in my over 50 years of machining. CNC has changed what can be easily machined so much.

the time you spent making this video is appreciated

[@SavageShooter93]

I used to service hoists with a cycloidal drive and it was a raging pain in the ass, it had something like 70 pins that needed to be removed, gauged, greased, replaced and reassembled but since the top plate was bolted to the top cover you had to lower it down without touching any of the pins (or you would knock them over) and I wore the edges off all the classic swear words and totally broke a few I invented just for that particular job. Cool project, thanks for reminding me of that particular slice of hell.

You got Leeloo The Fith Element to help unbox your bandsaw. Respect.

It is really, really hard to stop myself watching this video. I needed a break at 10:00 and struggled to avert the gaze until 24:00. I have finally done it and can make a cup of tea. What a content.

I have no idea what you are talking about with this entire video, but it has been satisfying watching you do it. GG

[@AnomalousVixel]

okay, now THAT'S a solid sponsorship segment... literally went half of it without realizing I was still watching a sponsorship segment.

I relate this video immensely. This is what I would do with more time and money and no distractions of wife, kids, and responsibilities. LOVE IT. Thank you.

If this is a commercial, it is the best and perfect i ever saw. Ranked #2 after "Die Mutter aller Imagefilme" (the mother of all imageclips).

[@juliuspekar7620]

i liked you as soon as you started talking. I like the way you do things, YOU FIND YOUR OWN WAYS. very aware of what may come if you were to go a certain route "foresee"

when someone has complete proficiency at both machining and commercial video writing & editing...the public wins.
