I see a lot of comments about not properly aligning the center to the new outside grind. While these people are correct in stating the importance of doing so, they are fundamentally a rather important point. Do you notice the size of that gear? The amount of tolerance you can have being out of round for the engagement with its mating gear is far far more lax than smaller gears most people have experience with. This combined with the end product ONLY NEEDS TO BE AS PRECISE as the machine it’s going into. For slower moving large gears being mated with a gear that is probably extremely worn already and operating in an environment where cleanliness, precision, longevity and everything else ALL COME as after thoughts to WILL IT FUNCTION AS NEEDED. My bet is these guys are very aware of what level of precision is needed to get the original machine functioning again,
Это тот случай, когда улучшать - только портить. Сточить зубы косозубого колеса с твердостью поверхностного слоя 65HRC резцом из быстрорежущей стали с твердостью 60-62HRC уже показывает уровень качества. Так что отсутствие радиального биения зубчатого венца, относительно оси детали на уровне 0.01 мм - меньшее из зол. И оскомину набил вопрос, почему показывают ремонт, а не работу отремонтированных деталей(риторический вопрос).
I have never seen a positive comment from a Russian, ever. I guess when you're mighty Russia and cannot beat a small nation like Ukraine in battle after fighting three and a half years, there's no positivity left in your life...
вам не понять русских, мы в отличии от пиндосов, не стираем города с лица земли вместе мирными людьми. а не пишем положительные комментарии на подобные видео, потому что не привыкли подхалимничать, а предпочитаем сказать правду, хоть она и неприятная. впрочем, отрицательные комментарии здесь оставили не только русские, понимающие в технике люди, сразу увидели что работа произведена очень некачественно и с огромными трудозатратами. можно было сделать намного качественнее и быстрее.
But what about the appalling non concentricity of the damaged gear when it was being turned off and then the ' thread' put on? The thing is at least 200 thou out of concentricity. The finished gear will end up going in and out of engagement with its neighbour.
Never worked in a machine shop? The casting looks like it's out of round, but the center hole is bored, and the outer surface is parallel to it. And as you can see, it's perfectly machined and still parallel to the center bore.
Just the vibration of cutting the teeth off that gear would drive me crazy... I will say that they make do with what they have at their disposal!!!! 😁😁😁
I admire the hard work, but this is not good. The inner bore was not centered to start with and that ruins it. 2nd thing is that both should have been machined smooth with a too tight fit. Then the inner could have been chilled and the outer ring heated and the two halfs put together then.

Super. Muy inteligentes y no se dejan varar. Felicitaciones.
i may sound a bit ignorabt but should the part be better centered in the chuck
This is Pakistan! In addition, the gear does not shine with quality either... And it will do!

Your skills are very good. I need to learn a lot from you
Pregunto porque no sé! Pero no lo dejó muy fino al engranaje no le sacó demasiado con el torno y le quedó poco cuerpo???
Very good.👍👍👍
Super jest to zrobione pomyślane i wytoczony pozdrawiam serdecznie.👍👍👍👍👍👍👍👍
You are very talented with your job 👍
@@paultabone2010 thank you so much…
He welded it then turned the weld off?
This job has a very tight tolerance
It fits where it touches 😉
Très beau travail 👍!
Perfect.
Биение не устранили теперь агрегат будет шуметь и не долго будет работать, будет износ. Мастер за изобретательноть 5 а за работу 2.
Now that was patience and attention to detail to get te fit correct and maintain the proper diameter on the gear. Nicely done sir. 😊

Its nonsense holding gear by not finished surface it's dumb because inside hole will not be in center after all he must use center hole
У него там биение жесть будет

@jimmyplain7583 it can be parallel but not perfectly in center even half mm can damage gear.
@@jimmyplain7583 No, he did not center the inner bore on the machine, watch when he takes it off, you can see.
Very poor workmanship, the bore was not centred by dial indicator. It is not true in parallel or angularity. The bore clearly has runout.
je vois pas trop l’intérêt de faire un filetage,tu emboites les deux pièces tu soudes et puis c'est bon
Bravo complimenti
Excellent job but i think its better to add some pins in addition to welding to ensure it will last longer
grind a chip breaker into your carbide may help
Excelent better than most U Tube vidieo Bernard Glasgow Scotland
Не уверен, у шестерни будет биение относительно центра
You know what kind of stuff I can make with a machine like that here in the US I would love to find one like that... People charge 7k + for one....
Офигеть, при помощи рулетки такую точную деталь выточить.
Точную? Не факт 😂
@@Alex_Ander77 Это был сарказм!
Muito bom
the hub is not centered will wobble
good bit of clever engineering much learning
Ты еще скажи геной инженерии металла.
It looks that centre is not aligned.
Good work 👍
wow recycled indeed.. RESPECT SIR.
Just the vibration of cutting the teeth off that gear would drive me crazy... I will say that they make do with what they have at their disposal!!!! 😁😁😁
Not sure what this gear goes on but I'm guessing the machine must vibrate like hell with a off center gear like that😂

Congratulation very good work
Definitely precise
Очень хорошо, молодец.
В каком месте то хорошо?
no sure how strong this is compared to the original but the repair is genius.
Он его даже не поставил по центру!!!😂😂😂😂😂😂😂😂😂😂😂😂
Биение жесть конечно😅
Смысл в резьбе?
salam vean y aprendan
Wow that's some Mickey Mouse stuff going on here.
Качество работы очень низкое
М...да, самый поганый ремонт. Вместо того что бы наплавить пару тройку зубов шестерни, оттермичить и фрезернуть, такой бардак.
🥰🤲salamat kupchak ❤
You’ve heard of third world? This is like 8th or 9th world.
LMAO
Насколько же токарю насрать на свою работу, что биение почти в полсантиметра его нисколько не смущает.
Are you kidding me ?🤣🤣🤣
This one looks like it could really work! Not like a lot of the others.
I d not center
You have no respect for our time, don't you know about something called editing?
I am impressed
фуфло. не отцентровал. всё отвалится
