Most people cannot appreciate how truly amazing this is. I wouldn't have believed it if I didn't see it
I cannot believe the plastic gears didn't crumble inside. That's 700kg*cm of torque, absolutely insane.
@@arcsiz Maybe there's high amount of wear after prolonged usage. Still amazing any how.
@@huytranvan2754 At the end, you can see that all of the contact surfaces have roller bearings, so I wouldn't expect too much wear at all. Though material creep might cause issues under load
That's such a nice thing to say. I'm happy with it. Next is to replace the NEMA17 with a NEMA23 and see if I can lift 50Kg.
@Paul Gould I would love to see that❣️
Finally a decent short I'm actually interested in!
Thanks
44lbs that smooth on 3d printed parts. This is a feat just in how smooth it is with a lever that long.
The sound is encouraging. Neat work!
Wow, over 60 Nm! Impressive.
Such a strong little NEMA17
Bro just needs some tiktok edits, smash cuts and some giga chad theme music for that stepper and gear box now.
Amazing!
Thanks!
Lovely
Thanks
Awesome video! Please keep posting. I'm following :)
Hey very great project 😊 can you plz tell me about the size of stepper motor you used
Incredible torque
Since the belt reduction output torque is about 1.6 ft/pound you could replace it with a magnetic gear. I'm not sure what would be a more complex construction.
I've played around with magnetic gears. They don't have much torque handling.
@@PaulGouldRobotics That's the idea. Combine both the first stage may be okay. But you got a belt. It could help with efficiency I believe.
Can the hand go faster and how many reps can it do in a minute? I ask for a friend... 🤣
Great work! Do you performed some tests to measure the backlash?
what is the holding torque and at what rpm does the stepper rotating and and what is the speed and torque after gear reduction
😮 ahhh ouai il vraiment bcp trop chaud le gars 😐
Impressive! Just how big is the total reduction?
28:1 cycloidal, 3.6:1 5M HTD & 3.6:1 3M HTD timing belt reductions
360:1 total reduction
Would this work for building a robot arm like the ar4 robotic arm?
The cycloidal might have too much backlash for the ar4. Maybe my anti-backlash housing design with needle bearings and extra timing belt stages could work.
This is crazy bro lol my 3d prints keep failing at half the weight
Hello, is there any possible way to get the cad drawings or contact you about designing these gear drives?
CAD files at Thingiverse 5595805. I'm happy to chat to you on Instagram.
how strong stapper motor nema 17
Coud you tell what stepper drivier do you use, in my project of cyclodi drive with NEMA 23 motor and TB6600 driver i see little current and the tork is way lower than i expeceted, do you have any sygestions whot can i do?
I use the KL-4030 (40V @ 3A) and the 17hs24-2104s stepper motor. TB6600 is better. What is your NEMA23?
@@PaulGouldRobotics Thenk you for responding, i'm using JK57HS56-2504 nema 23 stepper motor with 1:19 reduction on my cycloid drive, and i could only lift about 4,5 kg on 15cm arm, wich is about 6,6 Nm, even on really low speeds. I didnt check the stall torque of the whole drive, but still i think thats really low.
I've just find out that you reduction was 360 and know i understand that you couldev lift that much. Really impresive stuff.
where can I find this bearing?

Dang, that's scary.
And no fishing cable...
Do you mean Capstan drives?
@@PaulGouldRobotics Yeah, I thought they were stronger?
Редуктор нелинейно вращается. Уже проходили такое.
Почему? Это обычный циклоидалтный редуктор. Добиться хорошей соостности на напечатанных деталях задача очень сложная, но в остальном ок.
@@dimarusful когда добьетесь линейности, то сообщите мне пожалуйста.
Plastic gear !!!
PLA+ 90% infill, 3 walls
44 ft/lbs? Thats pretty impressive.
It is stronger than me :-)
Great job! Was this printed with solid infill?
3 layers, 90% infill 0.4mm nozzle and PLA+
