Thanks for bringing back to life Constantisecu's invention, it's a really clever design. BTW, his patent was bought by General Motors and buried apparently because it wasn't used in any production car never.
I am an aircraft technician, I've worked on all sorts of planes, including some original WW1 biplane....I knew the name Constantinescu was familiar....something to do with propellers.....then I remembered, he invented the gun synchronisation mechanism which allowed guns to fire through the propeller directly forward.
Another brilliant inventer who's works seems to been almost completely forgotten.
I absolutely love your videos, you truly make me smile and enjoy the stuff you build. Thank you
Wow, thank you!
nice to see you cover a Romanian inverntor's ideea!
From Coandă to Karpen and Justin Capra you cold get your hand full for a year's worth of YT content 😂
I ave done stuff on Karpen and Coanda mate - Capra never inspired me tbh
@@ThinkingandTinkering wishing you would do Karpen cells again :))
I love this guy. His proof of concept stuff teaches us how to think. Robert M. really puts a lot of effort and though into every build. AMASING@
Fascinating. Such a clear visualisation, thank you. Immediately obvious that the pendulum could be replaced with any energy storage device including a spring, a gas cylinder or accumulator, an arrangement of magnets or even the flux of an electromagnetic field. The distance between the input shaft and output shaft could be variable, or the mechanical resistance of the storage device could be varied (if electromagnetic it could be electromagnetically controlled). That will get me thinking!
This is the video that got me to subscribe to your channel. I've drawn up my own version of this on Sketchup. I'm going to see what's involved with putting it on thingiverse. I've been enthralled with this device forever. Thank you so much for building your version.
Seems perfect for the variable output of a solar Stirling. Could start by trying the fluidyne, then the thermal lag, then the RMS magnetic displacer Stirling. 😁👍
Great point! cheers mate
I just watched the last Wintergatan youtube video about the Huygen Drive... I immediately thought about you 😅
nice heads up mate - i like it thank you for sharing
Dr. Smith, I believe you have discussed this before. But this would be a good place to bring it up again. The Owen 1916 magnetic transmission. It's from around the same timeline.
Excellent Robert. It expands my technical mind 😅
awesome mate
Amazing video! Thank you for sharing mate!
Glad you enjoyed it!
Anyone else getting the uneasy feeling that Robert is building the biggest version of Mousetrap ever seen?
lol - no mate - i will shrink this down - i am demonstrating the concept here
@@ThinkingandTinkering 😄
perfect breakfast viewing thanks
Yes, Constantinescu invented (among many other inventions) that great torque converter. Unfortunately it has a major flaw leading to fairly rapid mechanical failure. Constantinescu himself tried different high strength materials to overcome that and hoped that better materials will be available in the future to sustain the mechanical stress of the parts. Too bad he concentrated on materials, rather than finding the source of the failure. He would have find the issue and its easy fix.
Thanks for the info!
The inverse use could also be beneficial. A CVT to convert the variable speed input, to a constant speed output, specifically like in a wind capture generator.
I am not sure i see the need for it mate - especially for wind generation - what are you thinking? can you expand?
@ThinkingandTinkering
Instead of dumping the over voltage energy when the turbine spins too fast, attach the CVT to maintain a constant usable output voltage. Or provide the exact same output voltage throughout a range of wind speeds.
you could do that with a belt and pulley CVT couldn't you?
also - when i think about it a bit more wouldn't a Huygen's drive work well here?
@@ThinkingandTinkering
I would think so. Maybe a centrifugal governor to set the pulley gap.
Excellent!!! So interesting and helpful!
I am no linguist but I think the name ends with “cue” like pool cue, or queue like the line at the ATM.
Cheers, Robert!
cheers mate
You should have a museum of all your machines.
lol - cheers mate
😯very interesting
Thnx for exposing me to it, Rob !!!
The motor could be a stirling and the "weight" could be linear generator.
Somethinhg like that could be a "hub," where different kinds of energies cound be exchanged or used alternatively.
The hole in the pendulum shaft for the out, if you elongate to hole so that the pivot of the output could be shifted up or down, will alter the leverage angle for more variable control
AWESOME!
Glad you think so!
Fascinating.
I wonder why it's not used more!
The double jointed pendulum made me fear chaotic behaviour but I suppose the constraints on the output (and input) prevent the system from going crazy.
Maybe because it would shake itself apart
a problem is that it needs each pin and joint to be able to withstand 100% of the engine output plus 100% of the extra energy stored in the mass times the moment ratio. This may make it too heavy and too noisy (there will be some slack, and that's a source of noise) for use.
Because it's not used, there is a reason.
it was used mate - i don't know why it still isn't used
@@ThinkingandTinkering I'm thinking mechanical issues at high speed and high power. But that's a semi-educated guess.
There's got to a be a history of it somewhere.
i think they were extensively used on hand-driven railway trollies
The mechanical age was full of gizmos like that and it was so popular that the American Sherlock Holmes movie uses it quite a lot and the (so-called) "Steampunk" theme/idea is still with us. One would think such things can also be adapted to our electronic age for better performance. Is there some kind of electronic version of this?
I would be interested in the efficiency of friction heat production, being hydraulic or contact.
I love th😂is Rob!😂 And really want to tested this with the motor without a piston! /Mikael
Very Steam Punkish Rob! haha
Genius mechanism mate.
lol - cheers mate
geweldig!
Bedankt lol
I get how this work as you've explained it yet im a little confused, I tried looking this up and it says about a flywheel in some illustration's but most talk about the pendulum... So if it was made for a vehicle like it was manufactured would it *have a flywheel or *how does the pendulum still work in a moving car? Id imagine turning would throw off the occilations or is there a redundancy im overlooking? Either way thank you for your time and your videos, it's appreciated.
That's really clever I love it
cheers mate
I bet that thing could be designed to work rotationally by designing it as a flywheel where the one connection is offset from the middle, essentially using the wobble to store that energy.
All the thoughts on torque I would love to see you build a version of Skinners torque multiplier/gravity machine from the 1930's. So little footage of it unfortunately...
no I am not going to do that mate
Yes please do! Even if you just explain why it doesn't work!
mmm - that's a good point mate - cheers
I wonder if you could use magnets instead of gravity for the pendulum
give it a go mate and let us know how you get on
Could something like that be used in the power-train of a human/electric-powered bicycle or vehicle?
Like @vibe77guy , the inverse could take a variable speed input and provide a constant speed output.
@@obsculor Rob explained that the pendulum was for demonstration purposes and that real world versions of this mechanism have been used with flywheels in cars
More adaptive gearboxes, pretty please.
I tought it was the other cvt invented by a romanian, like in the 1920's, was made from two levers, Stefanescu I think was the inventor.
Totally saw you going with a scotch yoke, but eh, it's mechanically the same action. I have my concerns that the mechanism you chose for this demonstration would wear more quickly due to the torque applied.
Good grief, would never have thought of this😂🎉 so it uses gravity to store the energy or is it force and motion?
10:56 maybe if they also put brakes the car would have been more popular. Only having the accelerator seems like a recipe for a bad soup.
Hi Mate, Could you please give me the link to your online shop ? I'm having trouble finding it!! Cheers!
the shop is closed mate - I can't manage it any more I am afraid
Ahhh, that would explain it then! Thanks for the reply though!
@@ThinkingandTinkering
So the best torque converter would be a generator. With drive electric motors since you would be able to have a feedback loop to control the power output. Hybrids are great I guess.
A perhaps unrelated question. What in your estimation, is the device portrayed on the Trajan column?
no idea but it is probably a plutei or festucae - but no one really knows for sure
your way ahead of me Ithaught you were on about his interuptor for aro machine guns arllar Sopwith Cammel ttfn&ty
What did I miss, this seems rube Goldberg ish, I assume there's a future windmill needing torque regulator. But with the small wind things he does he does not need this. I need a m2 area wind thing. So get printing snap together big wind😅
you missed the end of the video it would seem lol
You forgot about the necessity of stabilizing the output of wind turbines.
no i didn't mate - just because i don't mention it doesn't mean i have forgotten it lol
How close is this to a centrifugal clutch? Thanks
not at all mate
Wonderful Video Rob... I was of the understanding that most modern automatic transmissions are of the Power Converter type, not the Torque Converter type...
do you mean a fluid coupling mate?
Can ugrinsky turbines work horizontally
Yes, but the reason it’s used vertically is so that wind can hit it from any direction.
yes
Constantinescu means constant
Good Belly Catch, Rob!!!
hey at least it has use mate lololol
@@ThinkingandTinkering Yea, I've found mine quite useful as well. Although, for health reasons, I've been working on losing mine.
lolol - i need to lose mine too mate lol
I love the noise it makes. Isn't the core effect roughly the same as connecting a flywheel to the input and output shafts via springs. Put a disc of springs on input and output sides of the flywheel to connect to matching discs on the same axle but connected to the input and output. Or use concentric rings with springs between them - flywheel ring between the input and output rings
no mate - you need to think of it in terms of levers with a moving fulcrum
@@ThinkingandTinkering I understand that - I was trying to avoid the translation to linear motion and back. The pendulum becomes a flywheel and gravity is replaced by the spring (which ought to logarithmic instead of linear to replace the pendulum )
clever mate - thank you for expanding both on your topic and my my mind - cheers mate
With all respect, there is no such thing as an oversized engine. :D
lolol - fair enough lol
It's not truly a constant torque converter if you can stall the output.
that's not right mate - enough force on any output will always stall it
@@ThinkingandTinkering I mean if you can stall it while the input is still moving. That means the "gear ratio" is changing. An example of a transmission that doesn't do that is a gear.
that makes no sense to me mate - if you hold onto a gear with a force above the input force it will stop the gear - I must be misunderstanding what you are saying - can you explain in a different way so i get it?
why not coupling it with the Tesla turbine, notorious for its low torque?
if weight is replaced by spring pulling it down. that might also facillitate adjustmnt
give it a go mate and let us know how you get on
