The Life of a Gear

[@samgorman5731]

Our formula student had an old metal flask welded in place for an oil catch ... no wonder these guys do so well.

[@VaibhavSarda]

Glad to be a mechanical engineer to understand where they DID show the machining part. Infact here's a few of the machining processes that they're shown: 0:34 Surface Grinding of Blank 0:53 Wire EDM to cut the profile (you really do get a machined gear out of that single process) They've also shown a lot of the measurement processes used nowadays, optical inspection etc.

[@IkarimTheCreature]

1:47 also shows vibratory tumbling of the gears to improve surface finish and remove burrs.

[@overunityinventor]

This is half life, you didn't show how does the gear dies.

[@hotcroc2856]

#GearsLiveMatter

[@danishdezembro1116]

Half process...

[@FirstLast-yh5vc]

This is formula student. In the lifetime of the car these gears are unlikely to break down, but it would have been nice to see it at the end of the season :D

[@gbornitz]

@@FirstLast-yh5vc This is Formula Student. The gear is probably designed to last 1000 km to save another 2 g of weight.

[@zhouzhou3785]

somehow let me remind the life of a bolt video from red bull racing.

[@capelli8275]

yeah, they go a lot of inspiration from that video, and it was very well made

[@riderscornernz8945]

Love this. I believe Red Bull did a similar one for a bolt a while ago

[@fervunk1143]

im pretty sure this was inspired by it.

[@khairulasri2070]

This video should be named the life of mechanical engineer

[@alexandresousa6136]

This is so satisfying to watch .. A raw piece of still being changed por something mechanical :D

[@MrRanggong]

Wow this just blows my mind. Who wouldve understood how many smart and dedicated people it takes to get everyday machinery we use to work correctly time and time again. I think the definition of hero's is wrong. If the lights ever go out you'll wish you knew one of these guys.

[@blinkmotorworks]

Amazing video. Deserves more likes and views

[@ariefrifqymjn]

Xade Red Bull's better

[@maxpayne438]

Xade nope, it kinda passes from blank to toothed gear in 3secs. Can't understand how they cut it and why the placed it underwater

[@brettlinton4933]

That was EDM, (Electrical discharge machining)

[@maxpayne438]

brettlinton why wasn't laser cut? And what's the machine that submerged the part?

[@ShyamUHS]

yes

[@josehdz6154]

The grind never stops

[@Gab199ProductionsOfficial]

We must transit motion boys..

[@mrpalaces]

Mechanical engineering it's best engineering

[@zephroth]

All that precision work then they throw it in a vibration grinding set and don't test the dimensions after...

[@MrEpicLion]

Yeah I was a little confused at that part.

[@YszapHun]

i believe the end dimensions were accurate when the vibration grinding was finished. of course they measure it afterwards too, but you also have to measure the part size BEFORE it is vibration grinded because when it is finished, it has to be the perfect size. this is done by testing the abrasives and setting the time and vibrational parameters on the machines. the first few gears made were obviously bad in size, but they adjusted the technology afterwards. this is called indirect measurement!

[@microbuilder]

That wasnt a grider, it was a tumbler, it simply breaks edges, doesnt really change dimensions.

[@ipadize]

depends on how long you let it tumble :)

[@jeffreybell7225]

This vibratory process is likely Accelerated Surface Finishing or (ASF). This method of vibratory finishing uses high density, non-abrasive media with the addition of a chemical accelerant to convert the surface of the part to a state that the asperities can be slowly honed down. This non-directional finish significantly reduces frictional coefficients, thus increasing wear resistance, decreasing crack propagation points and ultimately gaining operational life. Material removal can be negligible at millionths of an inch.

[@boomperson818]

and this is where the series takes off

[@bollingbollz9379]

It's amazing how far technology has come.

[@dietalkaa]

2:17 $11 usb microscope from ebay? :D

[@EngineeringAndRestoration]

You'd be surprised how common these things are in manufacturing. Easy to give a quick visual inspection and the quality is good enough just for that.

[@dietalkaa]

Yeah, thats awesome. I use them daily :P

[@adrianvonbrockdorff1091]

or maybe a $2000 Dino-lite ;)

[@vksgears839]

gear chennai

[@RexinOridle]

I can probably buy a 2017 BRZ with that money.

[@Uizzj]

A Brz? Might as well buy a civic

[@alexmoore5970]

jerardo rosales I own a brz and it's a phenomenal vehicle, drive one for yourself.

[@Evan2]

alex moore it looks great and it's cheap but it sure as hell isn't quick

[@alexmoore5970]

Buy a WRX, or a used Mustang Gt/ Camaro SS if you want quick, this car is a blast. I have fun revving it to the moon, taking corners like a fool, and just drove JDLs show car, I am excited about turbocharging my own. The show car was limited to 280whp, but trust me when I say that thing was a rocket.

[@hadrieneverard8121]

This gear actually has a funnier life than me

[@RaphaelCh]

It's by watching videos like this one that I realize that Mechanical Engineering was not a bad choice for me.

[@ADX420]

How familiar are you with the gears wars?

[@Baard2000]

The most crucial part: tooth surface preparation by either polishing ( @Roessler) , grinding or the arc wire machining is missing. Also the eventual coating with wcc or dlc ....would be nice. If regtulations allow.

[@jellegiesen4889]

Totally copied/inspired *Life of a bolt*

[@kappcave]

I think inspired ) itsnot so easy to make video like video by RedBull.

[@iRxyanDestinygtaandmoreL]

yep inspired, and who the fuck cares just enjoy the vid

[@pastorofmuppets7654]

Usain Bolt retired

[@lsx_moe]

Jelle Giesen this one was nicer

[@jellegiesen4889]

LAZERKONG thats true , but the idea has been copied . Wich is not a problem. With all the respect its a good video

[@I_know_what_im_talking_about]

😂 at this video for not getting ANY views while "Life of a bolt" got a million+ I guess people only typically watch the same type of video ONCE and move on to more important Facebook things.

[@kingmatthews5436]

Maybe because the other video is by Red Bull racing

[@raedwulfone]

Well ,You really can't expect as many Gear heads as Bolt heads,I'm serious planetary system to boot...

[@ahmedalansari786]

Its simple.. The bolt one was published by a channel with 246,000 subscribers.. and this one was published by a channel with only 246 subscribers.

[@colineverett6160]

RB's was better shot and edited as well.

[@Voluntarists]

It doesnt show the machining process here ..

[@hedley326]

These videos are incredible

[@phillipmcintosh6489]

I enjoyed the video however it seemed like a lot of processes were missing from the video although I'm no gear expert. At 0:54 you see what looks like a milling machine with a fine bit that seems to drill a hole less than a mm deep and makes sparks while doing so. If this is the pre-EDM stage I would have thought the hole would need to go right through the product in order to feed the wire of the EDM machine through it and yet it didn't. Next at 0:58 you see a magic machine that you just put in a blank and out comes a finished gear. I thought it was the EDM machine and yet not only has it done the vertical shaping (by EDM) but also the scalloping (don't know the correct term, rotary profiling??) as though it's been turned in a lathe. Are there machines that can do the rotary profile as well as the vertical profile? Lastly they show a completed planetary gear assembly that seems to be the drive unit that connects the electric motor of the kart looking thing (electric formula student??) to the wheel and hub, etc. As I say, I'm no expert so would appreciate someone explaining the processes and machines. Thanks in advance.

[@tarksable]

That end cars awesome. i want it now.

[@spike4850]

tarksable well just think about how much work went into making that one gear, and from that get a rough idea of how high the price would be.

[@djdisleksik2119]

Looks like I've ended up on my weird recommendations again

[@sskorch82]

So they sent the part off to be tumbled and heat treated? I work for a company that can do everything shown in the video without sending off the part.

[@ruikazane5123]

man, without those we are dead already Thanks

[@LR-qi9rj]

never in my life have I seen a machinist wearing a lab coat

[@arnaldomanggalarahardja283]

It's more precious than a diamond

[@thegooserider7245]

Right, first off I would like to ask yet again! How the hell I got here? Second, I would like to know where to get one of those little F1 cars. They look AMAZING

[@dahalsuraj]

The attention to the detail given to f1 car parts is insane

[@dorianvincent2101]

It’s not F1 ^^

[@nobustrive1405]

Super quality product!!

[@nickfrechette19]

I love technology so much.... Incredible...

[@sitrakamatthieu]

Awesome vidéo!!! Bravo !

[@flashman_tv]

Missing a bit the important part of hardening.

[@UREindhoven]

Unfortunately not all processes could be included in the video.

[@r7z859]

Before this was a bolt, now a gear, im going places

[@SebyNeg]

Cool Video guys, very nice👍

[@NicotinJunky]

Planetary gear in Wheel, nice. But a shame you didn't show the tempering and grinding after.... and the Surfacemassurments not on the Flanks..... well..

[@dha12oks]

You know what really grinds my gea... Sorry couldn't resist...

[@gokuljagannath]

Wanna know what grinds my gears? Perfection.

[@binarynumbers7681]

What is the ”cutting”-procedure called? When the gear is formed out of the raw-material?

[@geniferteal4178]

Did you find out? Here I am a year later wondering the same thing.

[@geniferteal4178]

EDM is a thermal process for removing unwanted material by applying cycled discharging sparks in the gap between an electrode and a conductive workpiece. This method is typically used for machining refractory metals and hard materials, which are difficult to machine with conventional machining techniques.

[@phantommedia9964]

What's the music used in this video? I like it, thanks!

[@dalecook1206]

So, how much exactly do you know about the gear wars?

[@seanriopel3132]

Anyone know what controller the man was using with his left hand in the beginning?

[@Zkoon]

Cool video! But hey, a straight cut cylindrical gear? Come back when you have made the perfect conical gear 😉

[@micromachine7954]

So each wheel has an electric motor, with a planetary gear box that the actual wheel bolts to? Is this for torque multiplication or something?

[@hubertbehrendt1438]

It don't seem like a precision gear at all, I mean yeah little bit of surface grinding involved but apart from that EDM machined gear and spline, no gear/bore/O/D grinding involved nothing?

[@samhenninger3727]

Only wire EDM?? That's incredible if their process is so good it doesn't require hobbing or broaching!

[@seeker4430]

Could somebody list the processes that are shown in this video in making the gear? For the benefit of noobs

[@pawelzygmunciak3680]

What is the device the engineer operates by left hand @ 0:18 ? Is it a HW part of that CAD program?

[@x50music]

1:12 that part really grinds my gears

[@hugh6025]

cease

[@pastorofmuppets7654]

This changed my perception of Mechanical Engineers

[@MyFavoriteDisease]

Really? What did you think they would do?

[@pastorofmuppets7654]

I didn't know their work involved such extensive use of computer software.

[@fuesel2]

PastorOfMuppets now you know better. I even work with mechanical engineers who work with human tissues and membranes. This field is called soft tissue mechanics. The mechanical engineering field is incredibly wide and diverse.

[@pastorofmuppets7654]

Interesting!

[@BekirPerla]

What is the medium in 1:50 and 1:54 that Rosler use for polishing the gear?

[@nagesh007]

Wow amazing

[@empiirik]

You can imagine how much in such meticulously way producted gear will cost.

[@theclown6277]

a weapon to surpass a metal gear

[@boringsoren]

this almost madee cry

[@Js14561]

wait till they find out about home-depot

[@infaskjeeshorts5729]

just amazing!!!

[@ANabih-uo3zy]

When the life of a gear is more epic than your life as a human

[@maddoxinc1642]

A motor at each wheel would make ground clearance a lot more practical on a truck.

[@carplay5454]

i like the part where the gear is shown.

[@parthapratimsamanta3982]

which software you use for cad designing purpose

[@severalmalfunctions]

As a mechanical engineer this video made me laugh. 50% of the video were the people looking at the gear and the whole process was just wasteful. And what about hardening/surface treatments? Wven if the steel was already hardened they should apply a surface hardening treatment

[@beepboop69420]

not everything could be shown so they could only include certain parts

[@lubinlaison1216]

Which designing software do they use

[@commvaibhav1]

wow!! awesome!!

[@marach41]

Gearhead would be proud

[@jean-gabrielcanapa1225]

Amazing video :) 1:51 1:55 What are the names of the processes ? Deburring/Vibration polishing ?

[@michaellynch9862]

Vibratory finishing. It removes burrs and sharp corners

[@19koffing]

i dont know...but that second guy in the blue polo is pretty darn cute

[@estroncio64]

Do they use CMM for all the gears they make?

[@miyucafetokki66]

I guess it means that only one tire performs better than the others because it was equipped with a "perfect gear"

[@projectjt3149]

Looks similar to the "Life of a Bolt" video the Red Bull F1 team made.

[@JoeyLovesTrains]

Why does the into look like the same formatting to AutoVlog?

[@Rzkjr]

First half a minute is a massive advert for Microsoft tbh.

[@BranFlakesR1337]

LOL why do the scientists wear coats if they dont wear gloves nor goggles hah

[@petersvidler1590]

From my experience working in an eng lab, most of the time you're working with stuff that would badly stain your clothes, but won't do all that much to your skin. I've ruined more pairs of pants with machine grease than fingers with chemical burns... So wearing a lab coats usually makes sense

[@BranFlakesR1337]

okay so what you're saying is that they're okay with getting oil and grease on their hands and eyes but not their clothes haha

[@Crunchh]

On which software you design?

[@maxwell4444]

Powertrain Engineer: *drops it*

[@AnonymousF11]

Have you heard of the gear wars

[@tinyboxxx]

This is sick...

[@swikocki]

No checks for gear profile, lead, runout and pitching?

[@AbhishekSharma-gt7im]

That's called quality

[@dnltbrca]

No tempering?

[@UREindhoven]

The gears were tempered, but not all processes could be in the video.

[@stanbondarev9256]

it's disappointing me;/ Carburization and heat treatment is very important stage and maybe the most sophisticated comparing to that was shown.

[@slavepetrich]

This is making of the gear , it life starts when it assabled on a wehicle.

[@boshypatry]

And how much does that gear cost at the end?

[@creativelife4453]

really , gear story started with desgin, from hand to with report, many participate to give us one gear

[@ibrxhimmma8962]

i love this

[@What_was_wrong_w_jst_our_names]

Bruh this video made me think about life

[@markliu696]

hey man can I contact you？I want to make a four-motor racing car

[@geniferteal4178]

00:54 I think we're missing a lot of this process. It looked like a laser cutting device but then it goes under water or some other liquid and gets effectively machined? They are hiding the proprietary technology I'm just curious how that works I thought it was gonna cut the basic blank but apparently it didn't have to Cut through the metal. it cut 2 specific depths like a milling process. Anyone know the name? I'll look it up whatever this equipment is.

[@geniferteal4178]

EDM is a thermal process for removing unwanted material by applying cycled discharging sparks in the gap between an electrode and a conductive workpiece. This method is typically used for machining refractory metals and hard materials, which are difficult to machine with conventional machining techniques.

[@koningwillie6839]

Well redbull made such a vid a month before this clip with their f1 team

[@damarwirawan1348]

there will be a time where subatomic distance of precision are possible

[@xclimatexcoldxx]

That must be like $1000. That's a lot of work for a gear.

[@michaelkennedy8573]

Difference between quality engineering and "made in China"

[@Moucheron1990]

"How familiar are you with the Gear Wars?"

[@AlphaNerd132]

Was that a plasma torch that operated under water?!

[@IkarimTheCreature]

that was a wire edm machine, it's removing material by creating tiny sparks between a running wire and the work piece.

[@bibeksah4953]

So this is where red bull got the idea for the life of a bolt

[@adrian9098]

yhea 50 grams of gear and 2kg of paper... very good guys mother nature would totally love your work

[@Arctic-DX]

Get out of here.

[@akshayg7557]

do they use planetary system?

[@UREindhoven]

Yes, it is an in-wheel compoundend planetary gears set.

[@dontreadmyprofilepicture5209]

This video was more interesting than a MrClickbaitFTW video
