You're the first one to actually explain how these cycloidal drives work. And I've seen hundreds of them popping up as of lately 😊

It's operation is far more "wormlike" than the worm gear, it is a very cool drive gear, thanks for showing this one !

That is really amazing! Very interesting thing is how it behaves when you stop adding more power. Just adding some weight to that magnet disc will make it a much better flywheel. Then add some separation between gears and a flywheel (ratcheting or other also discussed in previous episodes) and we have a perfect device for a wind turbine 😊

If you increased the size of your magnets , which would increase the magnetic flux working on the serpentine coil, the mass would increase, which would allow for a bit of energy storage, giving you a smoothed relatively constant motion between gust of wind in a flywheel effect, Decreasing voltage fluctuations. Splendid Vlog as usual Rob.

Fantastic, you're making great progress! I'm learning a lot from your videos.

Really cool! I could use that on a bunch of my projects. Cheers to the inventor!

Also seems quieter than the more normal gears, which is nice bonus in a wind turbine.

Rolling sliding contact is most definitely the way to go Robert. Excellent lifespan from this design. Nice work fella too. Peace vf

That's really inspiring! 🤔 The extruded cam rides on the ridge only, leaving the trough free. If we adjust the shape it could be driven by water like an Archimedes screw in reverse using twisted cams, 2 would give you 24V Wish I had a tinker shop😂 Great videos, nice work 👏 thanks 😉

This is getting better and better... 👍👍

Bloody awesome, Rob. Can’t wait to see how it does in a breeze. Might be the ticket.

I just docovered your channel. You seam like an amazing guy and I'm probably going to binge watch your videos 🙂 BTW you probably heard it many times, but I get a stron Anthony Hopkins vibe from you

You're channel will grow with current world affairs. Sad way to be found, but amazing to listen to as an American. Thank you.

That's a great piece of work! Thanks!

Thanks for showing me something I haven’t seen before!😊

Why haven’t I found this channel until now!? This is totally my kinda stuff.

You Rock Robert! Good luck to yah Luke!

and the pleasant surprises continue with each video - as do the accolades...... bloody brill, Mate!

Easy to sand cast, looks like a winner!

incredible content for education and people seeking knew knowledge. Thank you.

brilliant, always look forward to your vids and mad explorations.....

Wow that looks very good! Thanks you for the clear explaination Rob, now I do understand it..😅😀 Cheers!

Nice example, I didn't know that those kind of gear transmission existed. Thanks for sharing.

Brilliant. That worked a treat.

That's really interesting, never seen one of these before, excellent!

Wonderful as always.

A quick google suggests these things are essentially free of backlash. If true, they would make great mechanisms for telescope pointing.

That eccentric cylcoid looks almost impossible to machine properly... luckily you can print it! The gear ratio is quite good too!

Very cool! ....looking forward to seeing which turbine you go with to power that....

Robert. Mate, you never cease to amaze me. I’m wondering where the venture capitalists are. Your blood, as my dear old Dad used to say, is worth bottling.

I think this man may be a literal genius.

Absolutely awesome.

What I like about this design is that your transmission gears won't break if your input is reversed for any reason. Your gear would simply and effortlessly reverse with no wear on the gear at all. You could also possibly use the same worm gear in tandem with another gear at the same time if you wanted and make it turn both gears, assuming your input is strong enough to turn both. One of the gears would turn the opposite direction, but that's none of these concerns (reversing or reversed extra gear) will be a problem for energy generation if the wires are connected to a full bridge rectifier, allowing constant and predictable output regardless of the direction the input turns. This concept could be used on any renewable power source that notoriously reverses direction, such as tidal or shoreline wave power where the ebb and flow of a wave can both be harnessed easily to generate power. Another perk to pinning this worm gear between 2 gears is that if there was any threat of the worm gear slipping from the main gear, it'll be drastically reduced if not eliminated completely by being pinned between two main gears.

Nice demo. Looks like that even with a 3-d printed plastic part, there's very little runout. Might be good for machine tool drives.

😊👍 Excellent! That worm drive, really _looks_ like a worm! .

This is highly viable in a variety of DIY configurations.

Great Video Great knowledge Thanks!!

Essentially a stack of very, very thin offset gears and cams. Clever!

Ya broke the camel's back, I'm all in now!

Thank you. I gotta try that cool worm drive. I made a triple helical stator and noticed a large reduction in driving torque 👍. I'm going to use floating magnetic bearings to reduce more friction and this worm drive looks like a great addition. I wonder how hard it would be to print one 😁👍

Nicely made. I sure will get myself a nice 3D printer soon enough. In the mean time i'll have to continue recycling old discarded junk like fishing reels to get my rpm up.

that was really cool

Excellent animations for instructiion!

Robert is a treasure to humanity

Awesome, love it 👍

16 volts... what did you get? Another great video And better content Mr Murray has gotten a great success! I am a fan for the videos to coooommeee!

DANG! 😵‍💫🙌 That's impressive!!!

Looks like, so long as you can keep it past its shift slip point, it should turn with relative ease. ~( 'w')/ Even though one may not see it as 'low friction' I see it as 'continuous impulse' which, in this case, sort of acts to reduce friction by always keeping some portion of the interface at the moment of peak mechanical advantage.

I said this before but i have to repeat myslef: You're a Genius!

Thank you Robert 👍👍👍👍👍👍👍👌👌👌👌👌👏👏👏👏👏👏

Good luck Luke.

Oh that's awesome. Almost flying.

My first thought is that there will be too much heat when you hook it to a wind generator. Can’t wait to see how it will work. Best of luck.

That is awesome!

Would this drive in metal need to be a wet gearbox aka: “oil bathed” for friction reduction? Or could a hard forged wheel be driven by a brass oilite or powdered metal pinion?

Thank You Anthony Hopkins.

Lovely... looks very 'natural' how the cogs/cam interact... seems like losses would be very minimal.

Very interesting 👌

Very interesting 👍

Would wrapping the serpentine coil around the sides and bottom (like c-channel) increase the generation? I would imagine the angle of the wire would matter a lot more.

Think this one may really be a winner. Let alone if u manage to up the ratio without putting much more force to turn it. Xxx

This Is CRAZY !

Seeing these videos always gives me inspiration to think up various designs to push these sorts of designs further, but i don't ever manage to try to design things properly. I could go online and find software to help me i'm sure, but never set aside the time properly. One thing tends to leave me wondering in the meantime though: You show the Voltage of these sorts of designs, but not usually any amperage to work out the Wattage. For this design, what IS the amperage? Could this alone charge a phone over a day? If it were even on with no data transfer, would it lose charge overall - just with the hand crank?

You would need a hypoid oil for any decent load on those gears, there is a large sliding bearing surface on those gears

This is very interesting, making a silicone mold so a wax copy can be made, for a lost wax casting from aluminum, using a old cast car rim, should hold up fine for a wind turbine, especially id pkaced inside a case, with a bit of tacky lubrication, a bit of lucas oil stabilizer, mixed with automatic transmission fluid, About 10% Lucas to 90% ATF, should make a thin oil that sticks to the gear leaving a film. For excellent lubrication. It will work well for tge bearings also, just leave a scroll pattern on the gear, to pull lube up to the axel, using a hollow axel, with a hole leading to bearing, it can be self lubricating. The oil running off the large gear, running into the axel, then to the next bearing, running out the axel, into the bearing, possibly have a scroll wheel just to pick up oil, and feed tge axel. Use a coil of about 3mm copper tubing, soldered to a copper disc. Feeding a roughly 1-3mm i.d. of the tube. With a 1mm hole to lube the bearings , with this system straight ATF can be used, no lucas added, the system would basically have a pump oiling the gears and bearings.. Im going a bit off an a tangent here. However, i have had the idea for a hybrid manual transmission, using a pump like a automatic, and clutches like an automatic or motorcycle, still using gears, only use the clutches to engage the gears, the shift lever only opens a hydraulic valve engaging the clutch, without pressure, they automatically disengage. With no friction, using a spring to separate the clutches, More like a motorcycle clutch i guess, having 6-8 packs per transmission, plus a normal clutch, that could be replaced by a valve, that slowly engaged the clutches, a normal 4speed transmission would be long, or possibly large, about the same as a automatic transmission. It could be setup to wirk automatically, uts like replacing the syncronesh with a clutch pack, about 8 3.5"-4" clutch disc and steels, maybe a smaller diameter for reverse, with less disc, being Reverse doesn't require holding lots of power, using a hydraulic coupling in place of a clutch, making it more like a automatic. Keeping all the gears from creating drag on the main shafts nearly eliminating the losseshaving one clutch connecting tge input shaft to the output shaft. Should not requiremire than a few hp to drive , normal losses are 25j+ hp or better at full power, this system should be 2-5hp, usjng a carbon ceramic on titanium with slotted steels1.5mm thick with .5 mm slots tge ceramic material having carbin fiber reinforcing it, basically a carbon composite, using a ceramic material with carbon inside, like porcelain with carbon using carbon fiber to reinforce, using powdered graphine to make a light weiggt ceramic making the clutch new, about 2.5-3.2mm thick the 2.5mm steels. Possibly baking the mose efficient transmission. Us live to build a eorking example, with a single pneumatic actuated clutch on each gear, having reverse, and 2 forward gears. And a electric motor, with most of the parts 3D printed, probably usung a sheet metal disc with a piece of paper from a brown paper bag . As the friction material. With another 20 gauge sheet metal for the clutch, and 3mm plastic fir the pressure discs, with a wavy flat wire spring, to spread the pressure disc off the clutch. Use a 3D printed standat clutch with paper as the friction material and simple pressure plate, and a dimple printed air compressor, and hollow cylinders to prove it works, using a electric motor, for spinning the gears. A car company could use the same transmission, only configured different to be manual or automatic, or possibly a option to be both. It could save money, save fuel , and be fun to drive,

hey question, what size bar are you using for the Coggs because they're not 8 mm but the bearings size are so are you drilling them out to eight mill and using an eight mil bar or are using a smaller bar in the bearing if possible can you tweak the STL files to have an 8 mm hole in all of the gears?

Actually very low ratio worm drives can be back driven. 5:1 is about the break over point.

Very clever.

Please sir, make more... I am addicted.

a worm gear can be reverse driven, but it takes a special set of circumstances for this to be true - if the coefficient of friction is less than the tangent of the lead angle, ie if you have a worm with a large tooth angle then it is possible with enough torque to back drive it, this is generally desirable if you are worm driving large and heavy components and dont want to have something break if the input stops suddenly, the friction and losses are enormous and brake the large heavy component quite quickly

if you make not only the inner part rotate, but also the outer part in the opposite direction, you get much more performance without forcing the parts made by the 3d printer too much, because it would share the stress on the whole machine.

Thanks!

Is it possible to change the big twisting gear into a water turbine (driven by water)?

ThankQ

Subscribed :-), that was fun

That’s awesome! 16 V is quite a lot for this arrangement, compared to what you’ve done before… but what if you could do a rotor that has magnets “inside” and “outside” the coil? Would that double the output?!?

Great video! (10 🕙)

What does this do different from a basic 10 to 1 gear?

I'm having trouble visualizing how you attached the coil to the frame.

What for amps was it putting out?

👍 getting there.

Could you make a video on making these gears and how you match the big gear to the smaller in tinkercad.

10x RPM not 10x speed. Since the magnet disc is larger there is another factor of magnification in speed that the magnets pass the coil based on the ratio of the diameters between the magnet disc and the driven gear. If the size of the magnet disc was increased with no other changes the speed of the magnets motion would increase too.

Hiya Robert ... I love your videos and ideas ... Please could I ask the amps for the 16v....

It would make quite a nice orbital gear

Looks like it would make a good fly wheel too after you stopped turning it . Can you stack these like the planet gears ⚙️??

Great idea to utilize wind mill as driver but maybe you will use stirling engine ? Mirror driven ? Ect ?THANKS SO VERY MUCH !

Could this be applied to bicycles to increase efficiency?

Oooh now I'm thinking if it'd be possible to use the quieter eccentric cycloidal gears in your stackable planetary gearbox , such as in your 1964 video A DIY Wind Turbine Gearbox.

Cool

do you have any videos showing how you learned to do all this in tinkercad, I teach engineering and it's always been a challenge to teach cad

I have a question that might help you! Have you considered an infinite variable gear setup at the initial point of the blades so that even a tiny breaze can keep the unit turning? Cheers.

We are getting very close now , we’ll actually you are getting very close to a system for green house heating, chimney heating and dare I say it a system to feed off my efforts when I do cycling on my indoor trainer, all obviously liked to small batteries or a series of batteries that will generate heat = wow looking forward to be warm this winter = wow plus two more wow’s.

Are you still working on that battery factory?

Would connecting 3 of those be spinnable?

Dear there r not much scientific temperament youtubers to breed problem solver generation. Thanks for ur efforts. Issue with u is u dont go and present in details. Pl be slow and explain the stuff in details. For example in this presentation. U cld explain how magic gears r different. And i saw coil type is different. Like zigzag instead of coils.

this would make a good bicycle powered power source, if you could turn the rear wheel into a flywheel and get it up to speed, and have that keeping the generator going, or some form of exercise gear that is modified cause it to spin a flywheel.

That's nice. How many amps? I hope Luke does great in school, I'm sure he will if he takes something that he's really interested in.

Looks like he got the idea from a supercharger, not sure which, but it’s whipple or twin screw or positive displacement.

4:06 Use two mirrors. The first will flip the image backwards, the second will flip it forwards again so you can read it. You can even put them off camera so we don't see them.
