non-circular gears and planetary gear

[Creaform003]

Whats the use of this? If you wish to rotate axles in a square through a planetary gearing system. one off the top of my head would be, put packing plastic on an axle off each cog and place a forklift palate in the middle, it will evenly wrap the plastic around, while being more compact and consistent then a circular design.

[murmashi]

what is the point?

[soverato3]

made in china...

[spindlerkart]

SHOW ! AGORA SÓ TEM QUE DESCOBRI PRA QUE QUI SERVE !!!! heheheheh

[wvadam]

it is cool but why? does this improve anything?

[anVlad11]

mindfuck.

[SpikeZeek]

but will it pump a fluid?

[mcgmark]

Soo amazing

[s8006]

ради чего?

[midinerd]

my god sesame chicken sounds delicious right now

[punkrock4everz]

lol autocad !!!!!!!!!!!!!!!!!!!! FTW

[chuckbear1961]

It would be Awsome to buy a set of these unusual gears to put on display at some of the local machinery show,

[circusboy90210]

wow a planetary gear. china should have been so mutch ahead in the manufacturing game. what happened to them?

[at1live]

Brb just going to fetch my chop sticks

[utupoe111]

oooh song? :D

[sterby1]

Zappyguy111 There were already non-circular gears in production and use for almost 20 years now, think about the Biopace gear on the bicycles. Same reason DayoftheGreek explained.

[Zappyguy111]

Great DayoftheGreek, you've gone and done it, now there's a practical purpose for these gears.

[AX53B60]

Awesome engineering :)

[enticed2zeitgeist]

Is this really cool? Or is this somehow better than circular gears? or both?! >.<

[drainocleanser]

masturbating is so much better than building stupid gears

[flaviolimaj]

Where can I find gear cool gears designs like those? ^^

Thanks in advance

[TheJimmax]

Very nice, I suspect you have too much time on your hands:-)

[Sunfadedlovejaded]

Ummmm...

There are circular gears there.

[bonkthetube]

meh

[AltRage]

Is it possible for a sane person to design these things?

[mrr1181]

What program did u use?

[Mikenopolis]

reminds me of how the Mazda Rotatory engine work!

[WarzSchoolchild]

@Mikenopolis Not just a Mazda Rotary engine, but also a potential 'Sterling Cycle' motor design as well. Those little beauties are extremely efficient, and this planet-gear concept could theoretically minimise friction losses.

[wildstyle666brooke]

hey look it's spiro-graph for grown ups!!!

[BlazeDeval]

dam asians..

[IKOLong]

pretty awesome design. lolz, surprised they didnt clean it better tho

[BRYAWN]

you can easily do it for cheaper with rods and ball joints

[SuperJunkiexl]

fucking geometrics and physics

I wish those fuckers would work for me like that!!

[SmoothAndNaughty]

Beautiful engineering! Simply amazing!

[Agentoxedo07]

Holy-Terrorist:>*=*

[lestersole]

tl;dr

But still, looks fantastic.

[tootiekorps]

shit's sophisticared

[danger2615]

those are so cool :P

[anusmcshitswab]

trippy

[BennitoJuarez]

Horray for AutoCAD!!! lol

[Agentoxedo07]

@BennitoJuarez Holy-Terrorist:>*=* AutoCAD, i knowed very hard price !

[evtom]

dude whats up with the music it freaking annoying

[Furnus105]

I'm a mechanic - gears always keep fascinating me, i love them

[klesmer]

@Furnus105 Amen Bro, I have recently retired after wrenching for 45 odd years and have to agree,this kind of stuff is fascinating as all getout.

[reap62]

you crazy asians and your math...

[Pancake6021]

what is it?

[tsaotsaotherebel]

@DayoftheGreek: Yah, I agree, perhaps in certain applications there is a cyclical demand on torque. I'm sure it would be a very low-rpm application.

[starexports99]

cool but why?

[happygamestvfun1]

mad with soliworks?

[maydayfire]

any technical advantage or just artwork?

[nerdykid136]

I want some of those on my bike! :D

[moneymaker739]

racist music

[richardmaudsley77]

@moneymaker739 You're dumb.

[Neoomegasonic]

@moneymaker739 How the fuck is the music racist?

[moneymaker739]

@Neoomegasonic azn are creative azn zong azn creations - azn videos i happen to be azn

[Neoomegasonic]

@moneymaker739 Asians are awesome, lol.

[sifterbox]

can we get a .eps or .ai file of some of these ?

[comodoro1986]

good music!!!

[grokker]

whats with the chinky music?

[snowman4839]

Guess who's brain just got fucked?

[coolbrandon92]

i like the music,

[Scorpion85629]

Mechanical Art! I love it.

[myskateboard16]

reminds me of a rotary engine

[NeKoShinn666]

These will replace bareings in 2 years :P

[loudoggg29]

0:25 GOOOO AUTO-CAD!

[TheIceychill2]

i love chinese music lol

[MPX4132]

not exactly what i was looking for but real nice to look @, that's real engineering...

[neoreaper99]

Curious...have any stress tests been done on these?

[erminthon88]

love the music. what's the name of the song?

[TYZL3RD0G]

Stoners would be amazed by this

[karmainds]

beautiful work, love the thought that has gone into it

[aznprc4lyfe]

i like the chinese music in the background

[malogames]

thats the most cool ass thing ive ever seen involving gears

[mrmaigo]

Would be fantastic clocks

[mrmaigo]

Would be a fantastic clock...

[sanpaco13]

Interesting, but what is the practical use?

[tobyiy]

@sanpaco13 to make people say "interesting indeed" :D :)

[taobmc]

similar principles were used in that crazy rx8 engine, rotary engine somethin or other, no cylinders just two triangular planetary gear thingies

[CalvinKostov]

what's the name of the song?

[DrOhcysp]

I can see the third gear system being used as some sort of rotary engine because of the expansion and contraction of the individual chambers. Who knows!...

[ChuffChuffWoo]

Some people have too much engineering talent!! Lovely :-))

[DanFrederiksen]

very nice

[Hot5hots]

Nice Monitor, LOL

[327yellow]

wow that planetary gear is amazing what complicates things even more is the position of the orbiting gears determines the shape of the outside gear

[billyrohnsen]

jeeeeeeeeez that's precision

[djbass101]

The design of some of those gears and that they work hurt my head...

[vTrolLv]

@orlx-Agreed

[orlx]

Crap music

[Ratysz]

I actually had an application for such unusual gearing systems - I needed a linear speed change for my pump idea... Apart from actual usability, they are very aesthetically pleasing :)

[Knowwon249]

WOOOOOOOOOOOOOOO!!!!

Solid works does everything!!!

[8osiris]

it's not the gears but the ratio of spin

[LOLDISNEYLAND]

how can gear systems like this be of greater benefit than regular circular gear systems?

[DayoftheGreek]

I think it has something to do with maximizing torque at certain parts of the rotation. If the thing you are driving the gears with has more power in a certain part of the stroke, the gears can help to either smooth the output torque or boost it when it is needed.

I might be wrong, so maybe someone else can comment.

[FlyingSnake110]

@DayoftheGreek

As far as I know (I study on University of Technology) non-circular gears are used in pumps and hydraulic motors.

I don't know of any application that uses gears like this to transfer torque. Problem would be wear of teeth. (but I may be wrong, there may be some highly specialized applications)

[FlyingSnake110]

@DayoftheGreek

Some more info about that wear:

In normals gear sets number of teeth of two gears must not have any common divider. If there is common divider two teeth from both gears "meet" each other to often which is increasing wear and in result vibration.

[Urstupidumbass]

@DayoftheGreek No, It just wastes the energy. It looks like its giving power. But this is pointless and thats why we don't see it inside any technology.

[3nasacova]

@DayoftheGreek This is a response to your comment on non-circular gears. You posted your comment over a year ago so you may have forgotten it.

If it were possible to increase or decrease the output torque with some form of gear configuration it would then be possible to construct a perpetual motion machine. One way would be to arrange them in a circle and use universal joints to connect their drive shafts together. If timed correctly, each one would add torque to the next one, indefinitely.

[mstory22]

who cares

[NimbusFilms]

So much awesomeness...

[SCIYER]

Good Engineering of non-circular gears. Well done.

[COROVICD]

Is there an application, or is this just engineering for engineering sake?

[SCIYER]

Oh. yes... There are applications in Assembly Automation, Indexing operations and Continuous motion machines.

[aarschgezicht]

non-circular gear are usually used in flow meters. the ones with the planatary I really dont know.

[gnator500]

does anyone else want an animated version of 0:45 ?or 1:01?

[aarschgezicht]

sure

[santiGTO]

you should send me some drawing files with measurements to make some of these on ma comp and machine them out. they look sweet.

[Nogorn]

two words HOLY SHIT

[4K4K1K0]

0:10 alternative Wankel engine? :D

[stabilini]

whats the point of making non circular planetary gears?

[FelchBelcher]

stabilini,

The point is a WHOLE NEW LEVEL OF PLANNED FAILURE!!! Isn't it great?

Interesting art but the ear piercing chink twang has to go.

[shinkengatsxa]

fuck off that song is awesome.

[FelchBelcher]

Oh, my bad, I thought the name of that song was, "I like dog soup and cat barbecue." I didn't know it was called, "fuck off."

[shinkengatsxa]

it still tastes better than anything your mother could cook.

anyway enough of your whore mother, the Chinese had gears/ clocks before anyone else. music is totally appropriate.

[FelchBelcher]

ABSOLUTELY WRONG! ever hear of folks called Sumerians, Imhotep and Egyptians?

AND finally a Chinese copy cat thief who admits to eating cats and dogs- well, at least you are honest.

[shinkengatsxa]

look man why don't you go jerk off a pyramid and leave peoples musical tastes on you tube alone.

[FelchBelcher]

@shinkengatsxa you go first, I'm still tired from your 200 Kg mom last night.

[shinkengatsxa]

well if your whore mother could cook she might be able to keep some meat oh her bones.

i have a great recipe for feline fondue if you would like.

[FelchBelcher]

SO, you rice ball, slit eye muthufuckus admit to eating cats and dogs now, that's a refreshing change.

[FelchBelcher]

Aryan and inbreed Looser, eh? even worse....

[shinkengatsxa]

its not inbreeding when im fucking your mom. also tell her she doesnt need to worry about paying me back her blowjobs were well worth it.

/also she told me your were adopted cause your dad is impotent.

[liOVERLOADil]

Seriously, mom and impotent jokes? What -- did your cookie cutter insult collection begin to stagnate in the mid 90's?

[shinkengatsxa]

look man this is youtube you can take it or leave it. it's not like i really care about your thoughts or opinions im not gonna put that much effort into it.

we both know we're only starting shit with one another to keep ourselves amused.

and on that note...

YOU sir, are a douche.

[liOVERLOADil]

Ahahaha!! You're absolutely correct! I really appreciate honesty like this, its actually refreshing to see someone so keen on what's really going on...fag.

[jamesandrew2000]

@shinkengatsxa Finally, thoughtful insight about those of us that start trouble on YouTube. Your measured response was both refreshing and informative. Also..you don't know shit about asymmetrical gears so suck it you fuckin' nascar faggot. Best regards. Jim.

[shinkengatsxa]

@jamesandrew2000 i just +1ed your comment

/nascar sucks where did you get that from?

[jamesandrew2000]

@shinkengatsxa Nothing but a random universal insult. Guaranteed to rankle.

[silverruby1]

@FelchBelcher u damn fool so what if they eat cat, rat,dog, goat, bear ect what have you accomplished by knowing that

shinkengatsxa not saying that you eat these stuff dude

[akilli1453]

Lovely!

[MacMachineMan]

must be hard to make lol

[tickdog2k7]

Symmetry, mearsurements, equal divisions etc. not too hard to create a basic one

[MacMachineMan]

haha im 14

im not that smart yet :P

[Ilyun]

Класс!

[throwawayacct2]

Music in the video is "Jasmine" done by the Twelve Girls Band, I believe.

[snipper1ie]

Surely you mean; You and I.

[mission2ridews]

Awsome gears. wanna fix my car?

[TheOriginalEntz]

my buddy needs to align his camshaft too :D

[TheIketastic]

obviously u have no interest in engineering and such

[soulstarter]

right...

[soulstarter]

who the hell would waste his time posting so pointless comments

[Alienated29]

I tried flagging this video because it says nothing about the musician.

[arcticfoxpi]

Faggot

[Alienated29]

FUCK YOU

[bibiwanax]

Your name really suits you... but isn't enough put into practice!!!

Don't say anything if it's nuts!!!

[arcticfoxpi]

NO U

[marcibb]

Neat

[drift2paul]

Those last few seem like they have fractal properties.

[benccollins]

ace thanks for posting

[Prowler1]

this is cool

[Cbeaky73]

very very cool

[nebunu1force]

cool looking...no doubt in that...

[atleastitsnotcrack]

A solution waiting for a problem some might say

[benpva16]

@atleastitsnotcrack That's gonna be a really cool problem, though!

[Minxcomix]

Spirograph!

[HostileLaw]

for what is it needed ?

[caulk04]

Even if it does not have a legitimate use in industry, it shows an engineering skill and manufacturing prowess. Not many people are able to think outside the box these days. Kudos, that is cool as hell!

[vwontheautobahn]

They really are amazing... Some artists could make some wild things with these

[EgadsNo]

@caulk04 this looks like it would be extremely promising as a gear pump

[hootinouts]

I cannot think of any practical use of the planetary arrangement demonstrated here. Also, those gear teeth would jam as soon as a load was applied to the train. Anyhow it look neat.

[dibbuck]

Thinking for a legitimate application is even harder than engineering these things - very clever though

[bccritters]

wow! if even one tooth is not right that whole thing would jam... excellent!

[DonHoraldo]

nice but like square wheels I have to ask whats the application?

[fbave]

I second that... and have the same question in my mind...

[ananiasacts]

It might encourage someone to come up with a theory that can enumerate the entire class or proper subsets of such mechanisms. As mini and micro machinery become more commonplace a wide variety of bizarre motions might be employed to transfer energy inside a device.

[BlindDogFulton]

Holy fuck! I wouldn't have believed it if I hadn't seen it in motion!

[pekepowah]

who made this awesome music??

[fancczf]

it's amazing but, what those things for? they seemed to be useless.

[timerider4]

How do you align the little gears and keep them from falling out?

[Triple88a]

wow this baby can be used as an internal combustion engine. Its perfect.. got intake, got compression there, a spot that expands for combustion and then decrease in volume for exhaust again.

[canarack]

You should look into rotary engines.

[Triple88a]

yes this is what i had in mind however this is with gears :D

[juniosonga333]

it's not as efficient as a proper wankeI

[Blondets1]

why do you think that? there are 4 narrow points that could be separated into two combustion cycles. That is right two power strokes per revolution could yield great power. The only thing is in figuring out how to have dependable seals

[Blondets1]

OOps there are 7 seperate chambers for 30-50 second type so there would be 14 power cycles.

[ralphieboogerbottoms]

I have a solar-powered windmill that uses the power of the ocean tides through the moon cycles generating magnetic forces to charge my electric toothbrush.

[bccritters]

why dont you just use the free energy of your arm?

[bballbill6]

what is the point?

[qwasdninja]

Im asking myself the very same question when i read your post.

[bellinivernon]

Muy lindo !! ;gracias , desde argentina.

[tubeofyou12xz0]

Is that last gear setup very efficient, or just it just not appear to be? That is still really nifty all those designs in general.
