As other comments say, this is not any sort of precision gear. But on top of that, how do you insure there are an integer number of teeth on the full circle, exactly?

[@GerardDick]

Serious skull sweat involved in getting the threads to stay aligned as the circle is completed. Diameter needs to be a precise multiple of the thread pitch.

Это не может заменить червячную пару. При большой нагрузке винт, который будет в роли червяка, просто сотрется очень быстро или вовсе потянет резьбу. Все таки у болта резьба работает не на трение, а на сдвиг и сразу всей длиной. Но на основе такой пары вполне можно сделать редуктор для невысокой нагрузки и непостоянной работы. Скажем, ворота пару раз в день открыть-закрыть, или небольшой груз поднимать изредка. В общем, схема хорошая и применение может найти.

@@AmazingTechnology1 я такое делал лет 35 назад, но по бронзе и диаметр был порядка 40мм. Не помню уже. Я переделывал мотор-редуктор дворников на фольксваген пассат В3. Там сожрало шестерню пластиковую. Оси дворников закисли, мотор тянет, тяжело ему, в итоге несколько зубьев просто срезало. Но там вся хитрость в том, что на этой шестерне выемки были, контакты, я уже не помню точно, и повторить это я не мог уже. Я точил кольцо с такими импровизированными зубьями, накатку изнутри сделал, шестерню проточил и напрессовал этот бронзовый венец. Он прекрасно держал нагрузку за счёт хорошей острой накатки внутри. Переделывать пришлось и конец вала двигателя, там же родной червяк уже не годился. В общем, было работы много. Б/у мотор-редуктор, оригинальный, стоил 140 долларов. Для меня дорого. Вот провёл такой эксперимент. Но дворники после этого двигались уже медленнее, шаг то более мелкий, а обороты те же. Приходилось использовать чаще ускоренный режим, чтобы компенсировать этот эффект. Но главное, что после очистки и смазки осей привода и установки туда подходящих резиновых колечек для уплотнения от воды, все работало нормально. И я так долго ездил, пока наконец купил новый узел. И таки да, я не сэр, я товарищ... Работяга родом из СССР, механик наладчик. Сэры - они все там, очень высоко.... 🤣✋✋✋

I used to cut nut threads the same way. Just set the lathe to the right pitch, set the right depth for the particular thread and let it go through once, and it is done. I made hundreds of threads without needing the grind/replace the carbide insert in a single point tool. I was making M70x1.5 threads.

[@jonesbugattis]

[@Tom-jx9te]

You have to have the diameter of the worm gear blank exactly correct for the pitch of the thread, called the circular pitch, or else as the worm gear rotates the threads won’t cut in the same place -they will double cut -and ruin the gear teeth

[@AmazingTechnology1]

You are correct
thank you

[@bogywankenobi3959]

EXACTLY! He is just hogging off material.

[@AmazingTechnology1]

@bogywankenobi3959 Steel Thanks

[@rogermarsh9806]

I’ve tried this method several times and it never works. Because the diameter of the blank is bigger than the circular pitch diameter as soon as the cutter connects the surface it will try to cut the number of teeth to suit that diameter. I have been gear cutting for over70 years and always use a dividing head and fly cutters which I make with the aid of a slide projector converted to a shadow graph. Amusingly my workshop is not big enough to get a 50:1 magnification so everything is drawn to a scale of 27.5 just to add spice to the working day.

[@bogywankenobi3959]

This is not a bad idea per se. But it is being executed wrong. Let me see if I can explain in words what I mean . . . When he is finished the center of the tap, or the axis of the tap, will be at (one of) the correct distance(s) from the center of the worm wheel. What he needs to do is start with the worm wheel (and thus the cross slide) already at its final position but with the worm wheel off to the right of the end of the tap. Then bring the wheel into the end of the tap until it starts turning under the influence of the tap. After a few rotations of the worm wheel, he could move the worm wheel to the left a little more and thus allow the tap to start cutting a little deeper. After a few more revolutions he again moves the wheel "deeper" into the end of the tap and keep this up until the wheel is being cut from the center of the tap. If the tap starts along the line that it will end up on, this method could work.

If you divided the circumference by the pitch and you have no decimals after the comma, then you have achieved it.

[@azarellediaz4892]

It’s not that hard if you know basic machining math.
1. Look at the “thread” around the gear as a flat surface; you need exact diameter at the center to do this.
2. You will need the exact pitch of the tap being used to proceed.
3. Divide the diameter of the gear blank by the pitch, adjust the blank diameter until you get the exact number of teeth required to go around the blank and the next tooth lines up perfectly to the next groove on the gear.

[@GnosisMan50]

It’s a good idea, but you can tell that at the end of his machining, the threads are not matching when it reaches a complete circle. He lost sight that the workpiece has to be a specific diameter in order for the pitch of the thread will match the circumference. Otherwise, he’s not going to get complete threads all the way around.

Very good job ! I'm an hobbyst, can i ask some details ?
If i use a tap with a pitch of 2,0 mm. and i want to get a ratio ( say for instance ) 1:40 , i should get a finished gear with 40 teeth and primitive circumference of 2 mm x 40 = 80 mm, which is a circle with a primitive diameter Dp = 80 / 3,14 = 25,48 mm. True ?
And a module m = D/z = 25,48 / 40 . Then i have to start from a external diameter which should be :
Dext = Dp + 2m = 25,48 + 2 ( 25,48 / 40 ) = 25,48 + 1,27 = 26,75 mm.
Starting to cut from such a diameter ( 26,75 mm ) should produce already 40 teeth from the beginning, no half tooth in any case ...

This guy is using a tap instead of a proper hob. Taps cut a triangular thread - this maximises friction so the bolt doesn't come loose. Gear teeth should have involute curve, which minimises friction.
He's done a pretty rough job anyway. The blank axis is nowhere near rigid enough - you see the blank tilt into the tap every time a flute comes into contact, thus cutting more deeply on one side than the other.

[@AmazingTechnology1]

Okay 👍

[@EJP286CRSKW]

He is also using a dead centre where he should be using a live centre, and he is lubricating the work instead of the cutter. Wastes a lot of time and oil lubricating the flat top surface instead. This is not a gear, it is a thread. And even granted using a tap he is using the wrong kind, a starter tap instead of a gun tap. Complete rubbish.

[@keithammleter3824]

@@EJP286CRSKW : It is so wrong to use a threading tap, I don't think it matters whether it's a starter tap or any other tap - the tooth profile is totally wrong in any case. He's actually using an intermediate tap.
If he is too mean or cheap to buy or make a proper hob, he's not going to spend on a live centre.
Did you notice he has to reach into the gearbox to change speed. So the gear change mechanism is broken, Not surprising the way these guys treat their machines.

[@hasturm1232]

Buono come lavoro, ma bisogna tenere conto del diametro iniziale ed andare con un avanzamento maggiore all'inizio. Per capire, se ho un avanzamento pari a 2 mm ed il diametro non è un multiplo di 2 mm avrò un dente "parziale". La larghezza della gola poi si allarga troppo. La prima passata andrebbe molto lenta e profonda, magari lavorando con "maschi" a diverso diametro e sostituendoli per gli step di rifiniture. In pratica durante la lavorazione si corregge da solo e lo si può valutare visivamente ma mantenendosi più vicino possibile al diametro finale può evitare delle gole di lavorazione troppo larghe e denti di diversa larghezza, migliorando in precisione e riducendo i giochi di scorrimento.

Unientity was 100% correct. Gears require laser precision cuts. Way too risky to use when cut like this. I’ve been cutting gears my whole life and we use lasers. Never grinding. Way way too risky.

[@taxicamel]

I have no idea who or what "Unientity " is, but I see no such entry or commenter. No one uses "lasers" to manufacturer gears unless they are very light-duty this spur gears with next to no precision whatsoever. High quality gears of all types, that drive with power, are made by grinding. Sadly it is very questionable commenters who make comments like this that truly make people really dumb when they take this information as if it correct.
For EVERYONE who thinks I am the one who doesn't know what I am talking about .......DO YOUR OWN RESEARCH!!! GOOGLE FOR THE INFORMATION ......IT IS REALLY EASY TO DO.
I sold industrial machine tools of all kinds, for many years. I sold junky cheap machinery when customers refused to pay for good machinery, and I sold the expensive machinery when customers understood what the difference was. Conventional machines and CNC machines. Gear manufacturing equipment from FELLOWS, PFAUTER GEAR GRINDERS ...just to name a couple.
Laser cutting gears? Sure, when you're making gears out f wood or something else.
