I didn't hear "back drive" once!? UA-cam videos about cycloidal drive gearboxes aren't complete unless the creator says back drive at least 5 times! 😂 Great video
I do industrial robotics for a living, keep the video flowing. Most people in the industry take the actual robot for granted. I am still there, 10 years in, wowed by the mechanical marvel a serial robot is. I am more on the software side of things. Building tools to program them better/faster. You will certainly have some nice challenges ahead when you get to the control, calibration, motion planning part.
For suggestions, I would recommend considering your pressures angles. It looks like the lowest the pressure angle on your lobe is maybe 60 or 70 deg. These high pressure angles effectively multiply the contact stress on your lobes because to transmit any force circumferentially you end up squeezing radially with a much higher force. A higher eccentricity and smaller pin/roller ring will improve this.
Another interesting variation on the cycloidal drive is the compound cycloidal drive, where there are are again two cycloid gears, but they are attached directly, so without an inner ring. One of the cycloid gears has one lobe less than the other, very similar to how a compound planetary gear works. An advantage is that because it has no inner ring, it can be made very small and with very low part count
I love that type of cycloidal drive! I’ve actually managed to design and 3d print one that has an outer diameter of roughly 2cm and is fully print in place (its output is not useful and the whole thing is just for show) while still packing a 36:1 reduction!
i recently made a cycloidal drive for my final year project, it was a 2 stage 36:1. It was bulky. This seems interesting, i think imma give this a try.
I must say i skipped the video when it was uploaded. I didnt realised it was from your channel and only thaught wow another cycloidal drive. Today i thaught there was a long time until i watched a video from your channel. I cant say i am disapointed video is great
If it's possible to change the design a bit, the rotating parts seem almost 2D-like, so perfect for cutting on a simple 2.5D CNC machine or a water/laser cutter.
You should give Fiberlogy CTE HT a try for your functional mechanical parts. Like PETG it is a co-polyester but has almost none of PETG's weaknesses. It prints exceptionally well in an enclosed printer and has no warping or dimensional issues. This stuff is accurate. It's also one of the most strong materials in the FDM world not just because of it's material properties but because of how cohesive it prints when you get your settings dialed in. Reach out if you need filament or print profiles. I print mine on a P1S but an X1C would be better because you can get the hotbed a lil hotter. If you want a similar material but with just a bit more flex, ColorFabb HT is of a similar composition to the Fiberlogy stuff but just a bit less strong. Still exceptionally good in terms of strength but especially the dimensional stability and print cohesiveness. Bonus, the temperature resistance of this stuff is some of the best you can get in an affordable material. Friction heating or heating from your motors will not be an issue with it.
I’ve played with some engineering filaments over the years. Mostly CF-PC and while I’ve found that there are improvements. You still have to deal with plastic deformation. I haven’t played with any of the newer stuff yet though. Thanks for the tips!
I really enjoy your videos. You asked for improvement ideas, and I would love to see you have a go at machining the disks in aluminum on your cnc. That’s one of the big advantages of cycloidals over other high ratio drives like strain wave, planetary, pinwheel worm drives, etc. They can be easily machined on a 2.5 axis system. Even a hobbiest cnc should give better tolerances in aluminum than a 3d printer in plastic, reducing or eliminating backlash and the stuttering. The load bearing will be far greater, improving the torque. And the stiffness will be much greater, reducing the hysteresis. If your little cnc is up to the task, that would be really cool to see.
@Cinema_Mechanics with 3d plastic I doubt your profile tolerance is much better than +/- .1 mm. I imagine your cnc should be able to do better. Maybe a lot better.
I always love your videos, and im certainly not a medical professional, but your fingers look really clubbed. I could be wrong, but UA-cam cant afford to be losing promising new creators these days!
im absolutely interested if you can make a compound cycloidal with this same style and have the inner and outer pinstack spin separate smaller within the larger i would be amazed if that would work, honestly cant follow the forces in my head so im struggling to work it out
Speed and mass moment of inertia would need to match. Mass and lobes can differ, you'd probably have to shift around the "speed holes" to compensate. (I agree that mass is probably very similar to achieve this)
One of these days I'm going to have to try one of these, as you say, everyone waxes lyrical about their advantages. for my robot arm I'm using a couple of 3 stage planetary gearboxes which I setup with 4 planets per stage to help with the teeth contact area thing. steel pins through the planets connect the output plates. I've had some decent success with around 50Nm of torque. they're pretty big though, and certainly the sun gear at each stacked stage is a week link. Do you think the stuttering movement you got was purely from the deformation of the plastic gears? I assume that was petg?
Yeah definitely recommend at least playing around with them. The stuttering comes from a lack of precision with the parts. For example if the shape is slightly off you can get tight spots and loose spots. Then as the disk deformed under load it got much worse. Using larger diameter rollers and longer rollers would have helped with this issue a lot.
what happen if both lobes count are equal ? you get a 0 at the bottom, does the output just not move anymore ? since effectively it's sitting at infinite gear ratio ?
Fiber reinforced PETG? Not carbon as it increases wear. The Oscillation was present at 1st run, and progressed? At 1st I thought too little torque from the brushless. Maybe friction played a big part?
The stuttering I’m pretty sure comes from a lack of precision in the 3d printed parts. Motor if anything is oversized for the reducer. It gets worse because the cycloid starts to get out of shape.
While speed and torque can be exchanged, power is absolute. A watt is a watt no matter what. If it takes say 5 watts to accelerate and maintain a mass at a given speed, and you're not putting at minimum 5 watts into the system (which youll of course have to input more than that for frictional losses in the bearings and contact points, plus rolling resistance, air resistance, etc) there is not enough energy (ie, power) to accelerate the mass to the speed. You can use that 5 watts to spin something light really fast, or you can use that 5 watts to lift something heavy slowly, but 5 watts is all you have. In physics, there are no free lunches.
You should see a doctor about your fingers 1. Clubbing: • This is when the tips of the fingers and nails become rounded and swollen. • Often associated with chronic low oxygen levels due to conditions like lung diseases (e.g., COPD, lung cancer), heart problems, or liver disease.
Hey man, just a heads up, but you may want to consult a doctor about your fingers, it looks like you have mild clubbing which could be a sign of lung or cardiovascular issues.
I spent a few years designing and testing cycloidal drives. This design will be nearly the worst torque ripple and non-linearity you can imagine. The multiple identical disks is the only way to average those out. But this design deletes that feature and there is no way to correct it in open loop control. SO its doomed from the beginning. Secondly, the differential type of gear reducers. like this, or a planetary wolfram drive, is the worst as well for constant ratio. Because if the ratio of 1 of the stages changes even a miniscule amount, the multiplication of the end ratio is changed much more than a simple 2 stage gearbox without this differential feature. 3rd. driving the disks with the output hub is much more difficult (to do smoothly) than driving the output hub with the disks like a normal cycloidal drive. I do really like the topic and your video was great. Just don't waste too much time on this. There is a reason nobody uses it, typically. If it is useful , Harmonic drives Inc. or Sumitomo buys them out and puts it in a drawer. True story.
Thanks so much for the thoughtful reply! I think I'm already seeing a bit of what you're predicting. I'll probably still play around a bit with the design anyway as I think it's valuable learning (for me anyway).
@@Cinema_Mechanics well you video was absolutely great. I could go for another. Let me know if you want to chat about cycloids. Maybe we could each learn a thing or two. I know I would. I have been down the rabbit hole with this.
My favourite bored mechanical engineering narrator comes back with another extremely interesting topic! Who knows where I'll use it? Is it going to be a 20°K mechanical testing machine?

Dude made a bunch of metal dowel pins when you can buy them over the counter.😂 Also, I second making any defirmed parts out of metal as other commentors have said. You have a cnc mill, you've proven the design with 3d printed parts, now you can justify the time and expense to make them out of metal. Not sure I would make them out of aluminum though. They are small enough, the extra weight steel would add would be insignificant
Well I mean I cut them. From a precision rod. Wasn’t actually that big a deal. Not sure where you buy individual pins at exactly the right length you need but sounds like a handy place!
I think requirements for an industrial robot isn't changed from what our ancestors set ages ago :D Rigidity first. Imagine that all our motors are stopped, firmly, they could be removed and the inputs could be welded. Now imagine that you grab the end of your 1,5 meter long robot arm and yank it. Does it moved more than 1-2mm? An industial robot would be like a stone in this case, rigid as f___, so when I'm planning a robot arm I start with the thinking of where is it gonna move when all inputs are locked. For example 1 meret long robot arm, with 3kg payload plus the mass of the arm itself, we can count for at least 10kg of moving mass, which is about 100Nm when it's extended horizontally (and stationay!) When it moves, and we want to stop it fast horizontally, it can easily doubles that, plus safe margin. So that's the mindset of which all DIY robot creators should think when it comes to sizing their parts. ;)
@@Cinema_Mechanics Hi! I hope you're doing well :) and so the project! I hope i didn't scare you off or discourage you, I didn't meant to. I just wanted to say don't afraid of sizing the parts bigger, larger, beefier ;) We are not Kuka or Fanuc but with a machine shop like this you can achieve similar results with a little bit bigger parts, lager diameter joints, etc. than an "official" robot with the same span. And the robot will be perfectly fine. Function will dictate the form :)

Doesn't having a different number of lobes make them not perfectly counterbalance each other? Or do they just need to have the same mass?
Speed and mass moment of inertia would need to match. Mass and lobes can differ, you'd probably have to shift around the "speed holes" to compensate. (I agree that mass is probably very similar to achieve this)
