How Gearboxes Work

[vossovich]

Cool!

[dude2106]

A 5 speed lawn mover.. Whats next? Shopping trolleys with keyless entry, AC and powersteering?

No seriously why does it need 5 gears?

[CarbineGuy]

On minute I'm looking at 5 speed manual gearboxes in cars, the next minute, I'm looking at a lawn mower...what?

[ripacipa]

thank you for video!

[pablo2cabrera]

"notice the ratio" lol...I was watching the hole thing the same, had to backward couple of time to see the difference xD

Nice video

[MrNeoFromMatrix]

piece, piece, piece, piece.. xD

[moggsie3]

Nice - thanks!

[snviper]

Is the chain on the reverse gear the same on cars and the reason they "whine" when in reverse?

[myid9876543]

@snviper I don't know about the setup here, but the reason cars whine is that the normal forward gears are helical cut (see wikipedia: helical gears) and the reverse gears are straight cut (see wikipedia: straight-cut gears) for easier shifting into reverse. Helical gears are quiet under operation, thus they're used for the gears people use most.

[snviper]

@myid9876543 Thanks! I did some more research and found it out myself too. I suspected as much since I watch a lot of racing and they alo use straight cut gears, that's why the gearboxes whine so much.

[KRAUSER0130]

1:24 looks like toilet :D

[maxbhupi]

i like d way u explained d whole functioning of d gearbox...thanku :)

[PERFECTlONZ]

looks like sumbody took a dumb in ur gearbox bro

[rookerzzz]

nice, no synchronzers on that bad boy

[taipan342]

nice man thanks for making this clip

[2711365]

good it helps

[yesnikita]

Than you so much for this wonderful video! I got is at last!!! Thank you! Now I'd like to know what happens inside gears...

[Jongaist]

minha pica

[dougcosine1]

It would've been nice if you had explained why the ratio changes when the gear selector moves

[AwakeAIINight]

this is actually quite a good video to give those with limited mechanical knowledge a better understanding of the gearboxes

[xXDryDogXx]

hmm... try a wrench to hold the bolt???

[PimpBoy219]

slap some turbo in it lol

[torcunningham]

@roadrunnerblink. You might have noticed that there were grooves in the shaft where he was sliding the collar along to change gear. The slots have shift keys in them that are held by the collar, so when the collar is moved along the shaft the shift keys select each different gear. At 2:21 when the selecter is in neutral you can see the triangular bit of the shift key poking up next to first gear. As the collar is moved to the right this triangular bit of the shift key grabs each gear.

[roadrunnerblink]

I understand the concept of the that little sliding piece engaging so that the gear is now connected to the output shaft but what actually happens to make it connect?? does the gear suddenly grip the shaft? or is there a little rod that slots in to a hole or something? anyone got an animation or video of this? would be much appreciated.

[exnol]

Great video man. Thanks a lot.

I have a question BTW.

What is the role of that one big sided gear on the shaft that connects to the engine?

[envelope91]

This is one of the most common gearboxes, used even today in alot of lawnmovers with gearboxes. Alot of lawnmovers with this gearbox also does not need a clutch.

Instead, there is a minor delay before the gear is actually jumped into action.

[dahoboman]

It's got 1st/2nd gear, so you can mow up steep hills, and 5th gear, so you can cruise at a steady speed on the freeway

[MrTr0llol]

i just busted a load to this video

[5bananas1]

looks like a mission to drive

[ASNNetwork]

as u said, lil bit

[Sergeymac]

Like a Big AirSoft Gearbox!

[maagd7]

I have a Toyota AE111 GT year 97.

I need a six transmission gearbox (manual) for a 4AGE Blacktop engine 20valve.

email me: maagd7@intnet.mu

[zhhgao]

Thank you, you make it look so easy.

[shelstone66]

this actually taught me alot about the gearbox on my yukon! great video man

[Wankotf]

Thank you for your instructions!!!!

[TeoZMuff313]

Motocross bike gearbox, Just hold wide open and shift

[chuy805chuy]

wher did u get that!

i need to get one of those! =}

[Jacob6443]

i crushed my finger on a bike gear

[yamaharules100]

save ferris!

[Wrightis]

This was super educational! thanks

[bhavz89]

sweet ride...what's the 0 to 60 on this baby?

[ulfy01]

Jesus, this mower is a monster. 5 gears huh, how fast does that bad boy go?

[NotBadYeah]

Very well explained! Why is this video so popular in India?

[Boosted1981]

@NotBadYeah lol had to check myself...no kidding XD

thats pretty funnay :D

[john34261]

i have a more expert gearshift becauos it is more strong and very sharp just a connector so you will bleed

[asflis]

Very educational.

Thank you. :)

[shadooky]

"ferris gear drive lawn mower"...."belt drive, as you can see the belt's right there"

[TheAjslife]

do u know what grinds my gears?

[MrXxMancinoxX]

@TheAjslife not family guy I'm guessing???

[hotcokane]

excellent,

great video

[Joao92]

Great explanation!

[Expl01t3D]

[tga19463]

Thanks from Ukraine

[orafargolo]

Congratulations, man! Until now, this video was the best to explain me how a gearbox really works. Thanks!

[Feyyaz070]

dude thanks man greats from THE NETHERLANDS

[AltronZero]

Lawnmower Motor Sports, new Generation Shifting Action. Jokes aside, twas interesting, though you didn't explain how would the ring make the different ratios. That I must Learn.

[khalidpashamce]

Thanks a lot..

[RudyZombe]

This is very instructive. Thanks!.

[Sweetearthslug]

Very nice vid!  Very helpful

[specallez]

Excellent explanation! Really helpful, thanks!

[TheMtxrules]

Good explanation, better than some of those 3D animations over there

[kambengurooon]

thanks bro for this vid!

[kmharsha94]

ermm,,,,that sliding part requires that all parts are lined up.....can you pls tell me how thats done when all parts are spinning rapidly while engine is running????

[funnyman1776]

thanks, really simple but highly informative!

[envelope91]

I got a gearbox just like that one, i like it, because it has no clutch, instead, there is a small delay after you put in the gear, so to speak, it does not go into action imminently.

[godzac]

So my camry makes a big crunch noise any time I ever put it into 2nd gear, but this happens with no other gear. Would you guys know how to explain this from this video?

[AnotherDayInTheNJ]

@godzac only when you put it in the gear? or all the time in the gear?

[godzac]

@AnotherDayInTheNJ When I'm coming to a corner, sometimes I use the gears to slow down. Whenever I shift into second to do this, it makes a crunching sound and acts as though it struggles to move in place. It also behaves this way when changing from first into second quickly. I have to wait until I'm going very slow until I'm able to change into second without making this sound.

[ReiDiGera]

@godzac im no expert, but it sounds like your second gears synchro is kinda worn out

[jordanr1504]

@godzac sounds to me like the syncromesh has worn, if your goind down a gear from 3rd, put it into neutral, lift the clutch then put it back down then try and select 2nd. and do the same if your goin from 1st to 2nd but u may need to be goin abit faster so your car doesnt slow down as much

[christy2drag]

But where's the clutch?

[actionmethod]

I love the tone, it's like, I'm-an-MIT-guy-and-I-will-expl­ain-this-as-if-you-are-all-fiv­e-year-olds. :)

[SthealthRaider]

boats have like a thing that makes the prop move in different direction like to go forward and backward. is that a gearbox? i dont think so

[pepene93]

@SthealthRaider on most boats it is a sort of gearbox. some more advanced boats always spin the prop in the same direction, but they alter the angle of the blades to adjust thrust.

[SthealthRaider]

but how its called? turn cluch?

[super6plx]

I don't get how a car engine can still run while the vehicle doesn't move

like in a car you can be going backwards down a hill and in first gear accelerating at the same time.. I don't get it.

I just want to know what gears are responsible for allowing the engine to run so it's not LOCKED to the wheels, so when the engine spins a certain speed the wheels can spin at any speed while still having force applied to them (ie: accelerating while rolling backwards)

[pepene93]

@super6plx that depends. automatic transmission cars use a torque converter. what those do is they turn the engines rotational energy into hydraulic energy and back again. so it transfers force, but it can spin freely from the wheels to some degree. theyre not perfect, but they work. a car with manual transmission uses a clutch, so two plates, one connected to the transmission, and one to the engine. if the plates are together, power is transferred. if theyre apart, the engine is disconnected.

[super6plx]

@pepene93 man, there needs to be more smart people like you on the internet

sure there are plenty but wouldn't it be great if everyone was so smart? xD

[pepene93]

@pepene93 thanks, man! =D i wouldnt consider myself particularly smart, but i dont have a thing with cars, so id say i know a bit about them and how they work.

[rosnakey]

@super6plx what u are talking about is related to the clutch of a car, and P.S. if u release the clutch while going backwards on a hill and beeing in the first gear, the engine will stop. That's why when starting on a hill u need to syncronize the release of the hand brake (or normal brake) with the release of the clutch and the acceleration. And the few seconds when u are actually going backwards while accelerating is due to the flywheel slipping. Search car clutches for more info.

[roadrunnerblink]

i understand the concept of this but i just do not understand how the selector actually "grips" or "engages" the gears to the output shaft. can anyone explain this because in all the gearbox videos i have watched on here not one person explains how it works. thanks.

[Ritty5]

@roadrunnerblink Search youtube for "04 MG Gearbox, MGB" for a video by Universitymotorsltd. Helped me understand a little more...

[majid4tagh]

thanks alot, such a nice video

[sdjkqs]

nice video and clear sectional view of gear box.

i am much interested in understanding how clutch works with gear shift in either 2 wheeler vehicle or 4 wheeler vehicle.....which seems pretty demanding from you...... ;-)

[exmarkmetroguy]

nicee! same as my mower

[Leon112006]

nice video

[Smallgasengine1]

how come you don't replace it with a hydrostatic transmission its faster

[Smallgasengine1]

cool video

[stsk8stepally]

great job man!

[Xx69roadrunnerxX]

Awesome vid! 5/5! Great detailed info on the machine and tranny. Gotta love manual transmissions! Simple and reliable.

That was so nasty looking trans. fluid though. Looked like mud.

[Smallgasengine1]

its actually grease and gear oil

[Xx69roadrunnerxX]

Ya no shit!.... I looks nasty though, not clean oil.

[riverboy0501]

i learned alot about that is that how self propelled push mowers work to

[highdeserthater]

oh gotta question.

is this the same tranny that they used in older cars where you would neeed to double clutch? its simple outside design and inside design made me remember the tranny from a 60s dodge my neighbor fixed up.

[highdeserthater]

oh dear. lol havent heard that in a while!

nice tranny! nice piece of machinery! i like it. :) 5 stas

[67tr876]

great vid man !

[CamaroIROCInfantry]

I liked the gearbox piece. Very smooth looking. Nice informative video yet again! 5 stars.

[navaraute]

I wish you had kept the gears facing the same way in front of the camera through out the vid. Would have been a lot clearer. Nice vid all the same.

[Alexschoen14]

cool!

[HazakyProductions]

Long time no video, nice explanation! :)

[ils360]

i love the video 5*****
