The repair looks really good, but in that last shot I can tell just by looking at it the weld didn't get proper penetration. There shouldn't be a harsh line like that. I can't say if the entire weld didn't, but that edge sure didn't. The entire filler surface probably should have been cleaned via a little grinding prior to welding.
That edge might just be a bit of overhang from the lathe operation, made more obvious by the contrast. I get the same out of my cast iron gears..I can never get the weld dead flat with the rest of the gear without digging into the side of the rest of the gear so I wind up with that. Back lash in the carriage I suppose.
Should have done this with Tig. The guys smart, he just needs better tolls.. and yah.. some shoes wouldn't hurt either lol
Да ему туфли надо хорошие😅
Other than insufficient cleaning and poor welding, using an angle grinder to shape the welded tooth will never give him the correct angle on the drive or coast side of the tooth. If the angle is too steep, it will load the next tooth in line excessively. If the angle of the tooth is too shallow, it will load the previous tooth excessively. Either instance will result in more broken teeth.
Better cleaning, shielding adjacent teeth from splatter and using a high nickel rod would give the best possible life. Using a form ground carbide cutter in the lathe toolpost, he could have broached the tooth to be EXACTLY like all of the other teeth.
He needed a runout tab on the side so the start/stops would be outside the tooth edge and would machine off.
Я не устаю смотреть такие видосики. Когда совсем плохое настроение, включаю их и мне становится легче - как же много вокруг долбодятлов и самооценка, а с ней и настроение повышаются. Я считаю, что это терапевтические видосики, получше любого доктора психотерапевта!!!
мне тоже нравятся такого рода видео, я учусь в центре технического обучения и люблю сварку, этот человек хорошо работает, но его работу нужно немного довести до конца
И добавить нечего, нахер мозгоправы когда есть такие ролики)))
Особенно понравилось когда єто тело вставило шестерню в токарный с умным ебалом а потов тщательно все захуярил болгаркой ! Гений бл...!

It all depends on the gear tolerances. If these are loose-fitting gears, this repair may be adequate. But if the gears are tightly fitting, eyeball grinding is not good enough. The gears are likely to wear and clank and grind, perhaps wearing in to better conformance, perhaps to worse. Only time will tell.
I didn't think about that, but you are correct, I saw a few episodes on manufacturing machinery, and some of the gears they were making had to be within a certain tolerance, guided with a computerized cutting machine and checked within a tenth of a millimeter. 😦😦
if you look at the gear you will see that there is a lot of wear on one side so there is no way that it could ever be described as a "close fit" gear train.
doesn't it need hardening? maybe induction method best?
It only has to last long enough for the replacement part to arrive.
I did the same thing on the ring gear on a locomotive. Lasted a while and eventually they had to pull the engine and replace the gear. Kept them going anyway.
3rd world countries do what is needed with what they have, it is commendable, and good to keep repairing. If only new machines could be repaired like the old ones can be.
you think in a 3rd world country, that can't afford much, wouldn't want to do a poor repair job that breaks apart maybe causing more damage to more gears!
There is nothing even remotely "New" about this method of repairing broken gear teeth.
My family were doing this in their workshop back in the 1920's ( that is over 100 years ago) on steam engine gears.
In those days about the only welding rods that were available were early Quasi-Arc rods and the AC power source was very crude.
After the war we were running nearly 100 engine driven Lincoln, Petbow and Hobart welding sets.
The only difference being that welding power source and welding rod technology has come on in leaps and bounds since then.
Ps back then there was no such thing as an "Angle grinder" but we had the some of the very first Flex grinders that came into the UK back in the 1960's.
So the gears had to be set up on the "shaper" to re-cut the tooth profile.
It wasn't suggested that this was a new method.
@@tigerteff015 Look at the title of the video where it clearly states "A new method of repairing a broken tooth of....". Does that help clarify the error in your comment?
He got the welded tooth to very close conformity. Very nice for hand work, excellent.❤
If the weld was case hardened it might last but I think it will destroy the other undamaged gears.
Complain complain.. it needs to be hardened and forged etc.. this will work cause it is flexible as long as the sharp load is placed elsewhere on the gear it work
@@trexmidnite What is your educational attainment sir?
Супер мастер - эвольвенту болгаркой забацать смог
Я то же в шоке😂😂
Если мастер узнает что он сбацал эвольвенту болгаркой, следующая шестерня будет оплачиваться золотом!))
и нафик не нужен эвольвентомер , давече настраивал прибор )
И режимы закалки о отпуска.
И маска сварщику не нужна, без нее загар лучше ложится )
I want to see the machine working after this repair.
😫🤦
I've seen hundreds of these videos. One in a dozen they show the truck driving away. They never show if it still worked an hour, a day, or a month later. I bet, usually broken again.
@@georgegonzalez2476 That's right!

Hello Morning
Wishing all of you good health and a peaceful, joyful and happy new year
Модуль и эвольвента соблюдены, я спокоен.
Para un mecanismo sin grandes requerimientos puede servir como chapuza para salir del paso. En todo caso lo que se añade es otro material sin penetracion y el tallado con amoladora una barbaridad aunque sean dientes rectos.
What about hardeness of repaired teeth? Original has at least 55-60, but new one is just looking nice but does not have propertly characteristics.
Awesome work!
All is there it is to make the Gear Working I am worried about the Material of Electrode that it should be near to the Gear Material. Thanks for the Video.
This gear is steel but many gears are cast iron which are far more difficult to weld, Depending on the hardness of the gear itself this might last a long time.
Not if you're a good welder and the cast iron is quality.
@@77Avadon77 It's still a gamble, all cast iron has some impurities in it but yes some are better than others.
10:30 🤣🤣🤣 ну думаю, а где фрезер?? а вот и фрезер!! А сразу он угловой пилой не мог обойтись?? бор машинку возьми, лапоть! Нет, я уважаю рабочих людей и эти тонкости -- не по нашей вине, но повеселили меня, спасибо!
Мне интересно когда этот зуб снова отколится сколько он дел наделает 😢, а он больше чем уверен отлетит при хорошей нагрузки
Я у себя наваривал несколько зубов в кубовой мешалке. Поработал две смены. Разобрал. Зубы на половину стесались. Так, что это до жопы.
Мягкий без не калёный металл
Вот ия про тоже, кажись туфта полная ,а как же закалка и всё такое? И сколько это проработает?
@@user-pl4ny8oe6wда ни сколько. Метал не сварился адекватно друг с другом. Соединение чуть крепче, чем на поксипол
Отлететь не отлетит но вот подгонка на глаз это жесть. Что он есть что его нет сейчас этого зуба
Super Amano 👌🔥el arte ase el maestro
did similar on my lathe gears but i brased them works fine
Very nice.....
Can we get a floor vise like that from Harbor Freight?
Thank you for sharing👌👌👌👌👍
Primero no es algo nuevo, lo hacen en muchas partes del mundo.
Segundo, este tipo de reparaciones son "pañitos de agua tibia". Sirven para salir de un apuro momentaneo. Eventualmente esos dientes deberan repararse nuevamente puesto que las propiedades de esos materiales no es la misma que solo soldar y esmerilar. De hecho con solo calentar el material ya existen cambios importantes en la estructura metálica.
Normalmente las ruedas dentadas son aceros de alta dureza, generando resistencia al desgaste. Al calentar la zona, posiblemente produzca una cambio de fase, y lo q antes era resistente ahora ya no lo es.
Gee. The gears looked so BIG in the thumbnail.
welded incorrectly see the glaring gap in the weld(s) piled it on without removing all of the slag every time he poked at it with the rod a drop at a time
good try, though
That is definitely a new method. If that is cast iron that tooth will fall off by the time get your rickshaw started.

Cool work thanks 👍
Excelente trabalho, ótimo profissional

Ну хоть не ""Холодной сваркой"" !!!
It's good that you don't have a residual current circuit breaker that triggers the FI when the flex sparks fly into the power strip😅
Do you have twin disc 8501 series gearbox for sale? Both old and broken ones are fine!
Old method it work's but not long lasting in some case because grinding ,welding both are not so proper but it is hand work not shaper or milling machines.
Good job good effort excellent.
That's very good.
I'm excellente mechanikal enginieus and high class specjalista from Pakistan.
My quastion is, what is that "hardeness" iin metal, which you are talking about?
The gear will hardly generate a homokinetic movement. If the requirements are low, it is a solution to the problem.
Good joob 😍🥰
Until first running. You might as well use a glue) До первого запуска короче, с таким же успехом можно было на клей посадить.
Been watching these tird world mechanical technique of repairing cars and related parts; good efforts but all against modern technologies. Amazing
Thanks
Mr sneakers must be the bossman..
11:44 some of the gears look deformed like it was only engaging on the side that broke. Might be a shadow.

No Chair's? if not make one you have a Welder!
A gear cog is only as strong as it's weakest point.
Working with what you've got is admirable but how about bluing the gear in to the mating one. This is highly likely to vibrate its self to bits.
If the gear is steel the welded tooth will probably last as long as the others. Maybe longer.
sure no
Just wrong ...
Well, if the tooth is too hard, it will bend off. The core must be a bit more flexible than the surface and there aren't neither temperiong nor hardening. It will simply crach again and a bit lower this time. It is simple physics.
И сколько это отходит?
I know is a patch and is a nice work, But the lathe sparks shoe that the gear got a higher carbon content than the weld , is just a time to this to get to fail as welding damages cast metal
Car Starter ring gears on the flywheel 100 years ago had teeth renewed like this.
BRAVO ..
Я один не понял для чего снимался слепок, если всё остальное (кроме станка) делается "на глаз"? 😆
1:Dude makes the involute gear profile by hand with grinder...
2:He kills the hardened teeth with metal casting.
3: The repaired teeth and their surrounding are not hardened again.
What exactly is (new) in this method?

Интересно, как Вы закалили этот зуб? Какая твердость получилась?
То есть эвольвента "по болгарски" вас не смущает?))) Какая твердость! О чем вы говорите. Задача была восстановить зуб. Зуб восстановлен)))
The teeth on that gear are hardened. Unless he hardens the repair it won’t last very long!
sure it will . it's only 1 tooth. every old machinery repair book shows how they would braze back missing teeth with brass which is way softer that steel. it's been done forever.
Good works
Why do we need math and precise machinibg if we can do involute shape by hand? :)
Seems like an unneccessary amount of work just to finish with an angke grinder. Might as well have just built up the tooth with multiple passes on arc welder befire grinding it down.
They "repair" those parts just to put them on display in automotive museum in the departament with extremely botched repairs.
They will be used as a warning on how not to amend parts which lead to serious deadly accident.
manusia tidak akan kekurangan pikiran jika selalu kreatif . orang Pakistan adalah ahlinya 🎉
Какой марки электроды?
That wheel should be preheated first. There is no good connection between the wheel and the weld...
looks good, but that weld will not hold up unless that gear is just for timing, better off drilling then tapping a screw(s) into that area, and then weld it and grinding, or you get a proper HOT full penetration weld (but that cast material probably is full of junk inside it ) ...
that may be a steel gear . cast iron would not weld well at all and would crack.
MashaAllah
Thanks 🙏
That kind of welding leaves residual stresses in the material up to yield point. That makes the “repaired” tooth very weak indeed, i.e. it cannot transmit the original torque. 😒
its ok for low rpm and a gear tolerances that leeve yous whit some play and loose anyway repair all always made on old machine whit wear and some loose and play anyway it work for 5 years do so you jus gain 5 years
Why no one has thought of building a workbench yet is beyond me.
What is Gerari?
It is pronaunced Ferrari.
Good!

I don't see that holding very long
Если сломались зубья шестерни, значит она была неправильно спроектирована.
that angle grinder with no guard was giving me anxiety
You need to relax….I bet 50% of all angle grinders gave them removed.
interesting
I guess brazing hasn’t reached them yet
good job

It is always these guys wearing sandals and squatting on the ground. They don't understand how and why the things are made using a specific process. They just think that if it looks good, it will work good as well lmao.

Wow, using a table. That's a first.
Finest people !
And why is this a NEW technology? Nice handwork but nothing new
Well done
You can hang that gear on the wall. Definitely cannot go into a vehicle.
