Are tables illegal in Pakistan or what? Why is everything always on the floor?
Rare indeed.
Because it "rarely" works.
Especially with all that porosity.
And no bevel....
Ugh. This wouldn't pass day one of welding school.......
Yet these are the parts were all buying lol did ya see the one guy smoking the cutting bits lol
Why would he cut in a keyway if he was gonna weld it anyway?
I think the old gear was a cast iron piece and new gear bush was a high grade steel.
So my concern is how they weld cast iron with iron without proper heating.
Correct me if I wrong..
The old gear was hardened steel. Cast iron crumbles into tiny pieces like coarse sand when it is machined.
It's a lot like how I imagine things were here in England during the industrial revolution.... those machines may even have come from UK engineering plants that were shut down when all our machining and engineering was shut down and we just let China make everything... its a bit rough round the edges in the workshop not like a German factory for example but it's amazing too see what can be done still in these places.... wish there was more like this here ...can't beat creating somthing from a blank canvas
Ух ты! электронный штангенциркуль в ихних палестинах 😀 поставил лайк уже за это !И туда прогресс добрался.
Я так понимаю, что гравицапу из говна и палок сделать этим ребятам проблемы не составит
That was so painful to watch. The manufacturing of the gear blank had no reference to the bore at all. Then the hobbing of the gear was the same, no ference to the bore. The hobbing mandrel should have been a snug (not tight) fit to the bore so that the gear PCD was concentric to the bore, this was not the case. No craftsmanship at all. As for the welding and keyways??? and putting scrap pieces of metal in there to stop rotation of the 2 parts was atrocious, and to be honest the welding looked like bird poo. Don't say they do the best with what they have got, what they lack is gear cutting and general engineering know-how. The gear will run eccentric on the machine it is fitted on and be noisy and suffer from accelerated wear.
Who cares what you say
@@sammyd7857 I don't really care what you have to say, I am giving an honest appraisal as a professional mechanical engineer. If you post your shoddy work on TH-cam you have the sycophants, who have not got a clue, but will post 'Ooo superb, fantastic' because they've not got a clue either.
@@thepagan5432 have you done any tests that showed the results you pertain to know?
@@sammyd7857 A lifetime of being an engineering manager, primarily working in the gear and industrial, automotive, defence, aerospace gearbox industry. Extensive experience with top tier motor manufacturers. Traveling all across the UK, Europe, North America and Brazil modifying and repairing gearboxes and consulting on automotive gearing. I could go on, but I think there is enough there to satisfy anyone's curiosity. I am a qualified mechanical engineer, with further education at colleges and university.
@@thepagan5432 so you have no proof of your claims.
Им бы работать на разборках авто по восстановлению деталей.
He shouldn't have measured the ID of the flange at the edge because it tapers to a smaller diam where the web is. This means some loss of thickness under the teeth. Also cutting the keyways will weaken the cylindrical ring further. Whilst the keyways would certainly improve the shear strength of
the joint, a good weld shouldn't require them.
It may be the problem was they couldn't make a good weld to the cast iron centre hub. A better way than keyways would be to heat the ring and shrink it on to the hub before welding.
Üt az anyag a gépbe és ugy esztergáljátok,bravó!!!Nálatok AS szabvány van????,ahogy sikerül??
Hummm... a nessuno è venuto in mente che tra ghisa e acciao ci sono enormi differenze?,se l'ingranaggio originale era di ghisa un motivo c'è...
What is the point of machining keyways if the very next step is to weld the same pieces together?
After all that work you don't case harden the new gear? Trash.
Cutting teeth in mild steel will not last. The steel is way to soft.
good👍👍
Magyarul vakeráljatok ide bazzdmeg!!!
проще было новую изготовить чем этой херней заниматься, токарный есть, зубофрезер есть, все есть для изготовление шестерни, но нет они сделают порносварную шестерню
What kind of nonsense is that again? Gear gears are extremely hard that you can't easily roughen down on the lathe.
Excellent job! Great craftsmanship!👌👌👍🏻
This is how things are really done and not wait for someone to ship it from China !! we are so use to it that we don't use Our inventive anymore cheers !!
A very wonderful video. I wish you happiness from Saudi Arabia
Workig machine, presition
Good job
crazy videos, is so extreme it is likev a mixture of star wars and what ancient egypt must have been at some point.
amazing the works you do in these conditions
The amount of work that went into making this gear shows the true craftsmanship of this man.
Che lavoro fantastico che fanno i miei complimenti. !!!!!!
@lelerubens5290 lavoro fantasticamente inutile se avessi una formazione in meccanica e magari esperienza d'officina potresti capire il perchè...
Excellent camera work for us, good job.
We don’t need no stinking OSHA
harikasınız
Вот бы посмотреть видос, когда эта шестерня отработает свой ресурс и её привезут этому токарю чтоб он её срезал😂
Они скоро космолёт к Марсу отправят,хрен с ним в один конец,но отправят!
Very good 👍👍👍👍👍👍👍
Nice work!
Good job
👌👌👌👌👌👌👌
👍👍👍👍👍👍
👍👏👏👏
😘😘😘
👍👍👍
Amazing they use just the bolt tension to hold that blank in place- it would be pretty easy to turn a bushing to fit the shaft and the hole.
Also it is more important the teeth are cut concentric with the bore in the hub than the
OD of the ring because they were not both cut at a single setting. A bushing would help ensure this concentricity as well as resisting movement.
my big concern is the scatttering of those chippings.... its not realy safe with no safety gear
Верстак не изобретен
🤣🤣🤣🤣 bohhhrrr , Arbeitsmethoden wie im Mittelalter !!. Also wenn wir hier in Deutschland auch so arbeiten würden , ja dann gute Nacht .
