A complicated design with no benifit.

So 4 of them could comfortably run a single toaster.

You dont need chain engagement on the whole wheel.

I am a mechanical engineer and I have also designed a floating water turbine. This turbine is described in my public report KD 598 titled: "Ideas about the 3-bladed VIRYA-0.65 water turbine with 20° inclined shaft coupled to the generator of the VIRYA-2.68 windmill for 12 V or 24 V battery charging". The generator and the turbine rotor are directly coupled to each other without an accelerating transmission. I have my own non commercial website on which you can find this report for free at the menu KD-reports but my experience is that if I mention my website, my post will be removed. You find my website if you type Kragten Design at Google.

Impressive design my friend!

I made my shuriken using soda cans

My grandfather has used a wooden wheel as long as i can remember. With practice, you can mirror polish an edge!

Tolles Video. Ich habe viele Ideen bekommen.

I'm very excited to have this capability!

Nifty design and video!🌞 Worm gears might be worth investigating. Thanks for showing us.

super cool awesome, was wondering how many hours you had in it thanks

WHAT

😁We have patented an entirely new, low cost, hear-silent, ultra-efficient, *_infinitely variable_* , ultra-torque dense [small & light], high durability gear technology, called FrictionLess Gear, which is a reformulation of gearing theory sans any toothed wheels. The gear range can easily be >700:1 [ultra high gear rage possible] with a price a fraction that of the lowest priced competitor. Enables smaller batteries and/or longer range in EV's [Exploding Vehicles ;-0 ] . Legacy and novel applications abound. Retrofits of ALL existing bikes, even electrics, will be available. 😉A novel, low cost, near-silent, electric motor tech may be paired w the FrictionLess gear set.

Why not swap the outer chain to the outside of the main sprocket? You can use a spring loaded tensioner in the smaller drive sprocket to keep tension over time. Reduces friction, keeps the massive surface contact

I can see this having the same problems as a CVT. During extremely fast changes in input speed. The chain will completely bust. I can see this happening from freak waves. And wakes from container ships. Also sea or fresh water will inevitably find its way in, and weaken the chain.

That is baller, could you make a monocycle with it

That is amazing!

Nice design. I like how you recognised and discussed the shortcomings.

I love this it is amazing, and I have been thinking about how to get gear reduction cheaply at the wheel without using Unimog / Humvee / VW's kombi gear reduction hubs. Please share keep inventing ! this is a fantastic way to change ratios!

What exactly is this threading process called?

combine this with a chain driven cvt and a flow rate censor connected through a diffusion model to the cvt

W Polsce ten typ elektrowni wodnych opracowano około 10 lat temu.. Widziałem testy na wodzie. Jak chcesz to podeślę link.. Pozdrawiam

Very interesting! Did you consider using rope instead of the chainbelt? Since it is a large piece, might work and also super reduce machining cost

External wheel should be bearing on different surfaces than sprocket surfaces.

Не эффективно. Потери на трении и преодолении сил деформации цепи очень большие. Все это можно построить на планетарном редукторе.

There is a very simple way for your case. There are chains with ears. A chain like this, but at least 1" fasten to the outer ring. On the inside, the chain turns a small gear with 10 or so teeth. The small gear only works on one of its teeth, but since the teeth are large, it transmits the power well enough and the wear is weak From it with a smaller circuit, move to the second generator drive.

Your project showcases an impressive and sophisticated design, particularly in the complex drive converter system leading to the generator. Your technical skills and engineering capability are clearly outstanding. That said, as others have noted, relocating the power conversion and generator components into the pontoons could greatly enhance the design. This adjustment would allow you to incorporate a wide range of off-the-shelf components for converting rotary shaft power into electricity. Not only would this simplify assembly and construction, but it would also improve transportability. Additionally, housing these components in the pontoons would effectively protect them from water exposure. The waterwheel itself stands out as a particularly exciting feature. Optimizing its hydrodynamics to extract maximum power from river flow presents a fascinating and valuable engineering challenge. Overall, you've developed an exceptional and inspiring demonstration of engineering skill. Keep up the excellent work!

Great work, and great presentation!

As an engineer myself, I really appreciate implementation of any idea. Coming from a mostly theoretical background, I am always impressed with anyone that can realize an idea. From pen to production. Great job.

Only a idiot let run the the KI sound in double speed

Due to water and corrosion, I wonder if this could also be done using Silicone Rubber Timing Belts instead of chains? I would imagine the chain can get more torque, but if it is in water, maintenance may be a concern.

Looks cool, but inventing a way to use a chain on the inside seems like you're over-complicating the design. Usually when you are trying to do something that has never been done before, it is because you are doing it wrong. Sometimes, there is a new genius way, but start with design as form following function, not the other way around. It looks like you're trying to contain a gearbox inside a rotating hub while also constraining yourself to input and output on the same axis. State your problem first. Are these features absolutely required for this to function? Why is it so important to keep the shaft input and output on the same axis? You already have access to CNC to make the inverted sprocket, why not make planetary gears instead? Or, just make one ring gear and one internal gear where you have an idler sprocket, then modify your one set of external chain sprockets to spin on that idler and back the the hub.

If you wanted to, you could use my design for a transmission, but it does employ a planetary gear set. Between input shaft and output shaft that are connected to the sun gear, and the ring gear… The planet carrier carries magnets that pass, stationary wires, and generate electricity. So, all of the friction is turned into the generation of electricity to be used anywhere else. I designed it for a car so that the car can send the electricity to front electric wheel motors, but now I’m shifting over to another design that employs electrorhological fluids that partially engage, or fully engage, two counter rotating discs by sending an arc of electricity through them. In a design like you’re talking about, a person doesn’t have to use gears, you can use a belt with holes in it that is made out of UHMWPE, or Vectran, chains would be fine, but I would just use a plastic belt with holes in it. If you really want something that would help the environment, I wouldn’t mind if you were to represent this idea… The plastic trash dump in the center of the ocean that is the size of Texas, could have solar lensing, melt it, and froth it up with air, or sequestered CO2, to 80% foaming, and 20% solids, and it would be far, far, larger than Texas, and anchored to the floor of the ocean, it could generate electricity with the tides. Then, you’d be a hero for figuring out what to do with all of that plastic in the ocean. There is a certain kind of algae that will cling to it to keep the plastic from disintegrating into the water. The energy that it creates can create hydrogen through electrolysis, and the hydrogen safely stored on metal hydrides like that of plasma kinetics. These cartridges that safely store the solid hydrogen, can be transported by air boats to distribute the cartridges to the lands, where autonomous drones deliver these cartridges to peoples vehicles while they sleep, so they never have to worry about range, anxiety. Right now, I am in the process of redesigning and ideal adiabatic HCCI hydrogen, internal combustion engine, that has no touching parts, so it never wears out or needs maintenance of any kind. These motors fit inside the wheels of a car, and that’s why I was watching your video, because I thought that it was a variable speed transmission that was very compact. Since you’re dealing with water, you could have cups and contactless plungers that engage, and disengage as the teeth of a cog, and the water is slowly pressed out of the cup by the plunger before it fully disengages. This would mean that it is frictionless, and no touching parts means it would last a long time. It is a far less expensive approach than chains. This paragraph was edited and I didn’t feel like erasing the rest , so you’ll have to try to make sense of it. of a wheel that will act as gear teeth, but hold water that a contactless plunger can fill those cups, but slowly leak out the water before disengagement on another gear as teeth, and you would only have the friction of water. Plus, it would be really, really, cheap, and last for a long time because there’s no touching parts. Right now, I’m in the process of a new manufacturing technique that I call plasma forming. Atomic elements are heated to a plasma by microwaves and geometry shaped by electromagnetic field lines assisted by AI, and when the microwaves turned off the plasma collapses into solid objects that are dimensionally perfect in geometry. This means that a cylinder a very precise dimensional accuracy can barely fit into a plunger, and while it turns, there is no friction because of the layer of air in the boundary layer between the two moving surfaces. Someday we’ll be able to manufacture, frictionless, gears, etc., with no touching parts, and the acoustic resonance harmonic standing waves will use very little energy to support extreme loads. The plasma forming can make thousands of objects per second very inexpensively, and at that point, you could use that sort of technology for your transmission. I didn’t mean to throw you into a rabbit hole, I was just seeing if I could help. Good luck, and thank you.

In which software did you make generative design study?

Great to see more from you, I used to watch your homebuilt knives and slingshots religiously back in the day! Congratulations on the cool project. I really think that kind of approach is what the world needs. Simple stuff that can be built or maintained anywhere. About the gearbox, I guess the by far biggest downfall here is that the chain wants to unwrap itself from the inverse sprocket when you apply force to it. The reason chains usually work so well as you obviously know is because they are self tightening around the sprocket they run on. In your layout it's self untightening in a way. Another major issue I see is that the moment the chain start to length itself, you'll have issues of correct engagement at the rollers. I guess that that's probably why people usually use belts as they bring a bit more tolerance due to some flexibility in terms of correct engagement. Why didn't you base it on a motorcycle belt yourself? Those are also rather easily available, would the added width have been an issue for you?

Why not just use a planetary gearbox? This seems needlessly complicated.

very clever, good job

Impressive! Well done.

2500 nm is the sigma ?

Genial!!!

The idea is good, but the price of 2000 pounds seems like way too much. You need to reduce the price to under 400 pounds to have any use. Start thinking about low cost replacements for your parts. Diesel generators are way smaller, can be used anywhere and can be run with local oil and fat, reducing the potential cost of an entire day of runtime to a pound or less, if not at full power, all while costing under 500 pounds. potentially giving you 4 years of power for the same price, but not dependant on rivers. So while this might seem like a nice project, i doubt it will ever be used, aside from some white people going to africa to show off renewable energy as a youtube video or investor scam.

👌

Can you do a workshop/work room tour, what tools printers are you using?

10s across the board! Impressive work

Maybe you could weld the chain into a flange, to minimize the cost of the big internal gear.

It looks cool. I once built something similar for a packaging machine. The guide that holds the chain in place is going to wear down way sooner that you imagine - especially if you have load (that is what happened to me). . . Take a look at the gear system for a cement mixer (use that as inspiration)

I'm no engineer; if you were to make a separate sprocket that bolts onto and stands off from the water wheel, the chain could run on the out side. You may need only two tension pullies to keep the chain in contact with the smaller pullies. This may reduce the rotational speed?

Well that Inverse sprocket was a nice torque concept. Best wishes on your future.

I do not believe it is over complicated at all as mentioned. I saw no generator or pump in the design. Were you thinking of a self designed unit or off the shelf components ? LOL, funny after thought, if given shaft or cable drives from both sides, and further gear reduction at the ends of each drive shaft, this might be able to drag itself up stream. Probably very, very slowly, but still. 😁

I suggest putting the chain on the outside of the sprocket. I'm not making a joke... fix the chain in the place where your inverse sprocket is, in a circular path. It could be held by its link pins between two plates. Then you can use a conventional smaller sprocket on the inside, driven by the circular outer chain. Fix another sprocket to that one (slightly smaller diameter, yes, reduction ratio but necessary to fit) to drive your final chain stage.
