I came here after watching Pakastani workers, using very simple tools to build a very large gear. I am fascinated by both videos, the one with the simple tools and the one with the high precision tools.
This session of "I spy who doesn't belong" starts off on easy mode with the first 2 minutes of office workers trying to look like they do something on the floor
What I found amazing is how they let someone with long hair that is flopping all over around that machinery. I witnessed a person's hair get caught in a machine many years ago and it is something I hope to never see again.
....any idea what these gears go into? I can imagine a few places where they would wind up at, but to establish an entire company to make them must be a lot more uss for largest gears that I would think. Ships? Hydro electric dams? Wind turbines? What else?
@@texasengineer5511 Thanks highly. One of those things that make you wonder why they make them in the first place. Guess Three Gorges Dam in china took a lot of capacity also.
How does the synchronization between the thread cutter and the spindle work? Is it handled by the computer with rotary encoders? Or is there some kind of linkage?
When I was studying production engineering in the1980s CNC consisted of a DOS machine with 5.5" floppy discs controlling a punch cutter. Accuracy 0.5 mm How things move on.
Amazing process .I use to operate fellows gear cutting machines , a Hobber and a Gleason Bevel gear machines and you could never run at that speed . the rpm yes but the feed never ,They were consider manual ,still got it done ,very interesting ,We also cut Worms and splines .
Customer: hello, you have sent me the wrong gear. Factory: sorry, please send it back in original packaging and we make you another one before Christmas
after a career of machining spur gears up to 160 inch diameter 16-30 inch face, 18-24 inch bore and up 140 teeth i found this just astounding. i knew what i did was dinosaur technology, but i had no fricking idea it was this advanced. the one thing my gears would be considered a "bastard" size tooth profile, designed in such a way to be cost prohibitive for a competitor to buy a hob cutter to fit each gear and pretty much guarantee a gear replacement would come from us. [SUGAR MILL extraction]
@ Paul M I was wondering if you could tell us where these gears are being used. I am not suprised that these large gears provide a need. I am surprised that there is an entire industry, all over that can support itself by making them. I can imagine that the prevalence of windmills have increased the need for large gears. Where did they go before that. A few are needed for ships. Another few in the turbines that are behind making electricity at a water dam. How many more applications use extremely large gears? thanx.
It's Germany, so they would probably do something really horrible to whoever screwed up...like forbid him from drinking beer ever again. A fate worse than death, indeed.
The most gears you saw in the video are all made for the steel industry, the big once are used in gearboxes of hot rolling mills, some in converter tilting geraboxes etc.
Cargo ships (typically) use reciprocating diesel engines that run at the same (very low) RPM as the prop so a direct shaft is all that is needed. Gear trains like this are needed to convert high-RPM sources like gas and steam turbines, to a lower RPM for the prop shaft. From what I can tell, only military/naval vessels regularly use these in ships. I can imagine that large factories may use gear boxes on this scale too but I've no experience with that. That being said, I doubt power plants would need any gears like this because the electrical generators work at the same high RPM as the turbines. Funny thing, when I was in the Navy, it was well understood that the USN doesn't 'buy' the bull gears (the largest final gear in the train) for its ships and subs, it leases them!!! Who knows if that it true but if so, it sure speaks to the cost of such large-scale, precision machining.
The woman supervisor needs to cut her hair or otherwise contain it so she will not get dragged into the machinery. Basic safety consideration like taking off all rings and wearing short sleeve shirts.

Philadelphia Gear makes gears that big, I used to work for them. The big ones could be used for a mill, like a cement mill. I worked for Falk also they made bigger gears than that. The biggest was for a hydro turbine, about 40' in diameter.
...maybe you could tell why so many super large gears are needed? The comments tells us where a few individual ones are needed and used. Once thats done, where do all of the other ones go?
@@629Justme You have the main gear which ours are close to 50 feet in diameter and then you put generators around that gear through other gears so you have multiple generators being run on one gear.
@@nickreno644 Thanks. Any idea as to the number of applications for these large gears besides atomic submarines? Trying to get an idea where all of these super larges gears go besides power plants and electric boats.
Woman with long hair needs to see picture from Norfolk Naval Shipyard taken during WW2, in the inside machine shop. A woman lathe operator lost most of her scalp this way. The black and white photo was still stomach turning, and effective when I saw it over 40 years ago.
hehehehe our company has a gear sitting in the muck in Alexandria Egypt harbor , dropped from the cargo ship that sent a Missouri[usa] gear to New Orleans shipping company to Egypt. shipping insurance paid for us to build a new one......also have 2 gears sitting in a louisiana swamp after a train wreck. 2 new ones made to replace them too. i'm talking 2 140 in dia, 95 tooth spur gears 24 in face 18 in bore. the egypt gear was much bigger!
What ever happened to Western Gear in California? I know that the small work went to the applied technology division in Utah. Who is making the large Western Gear designed components similar to those shown in this video?
0:32, that ladies hair is too long, and her makeup will cause her to break out if she worked in a factory condition for long doing what she's pretending to be doing. (inspection). Conclusion: She doesn't really work in that factory, she's just a paid actress.... Why? If I'm wrong then I just complimented someone's unrealistic appearance.

The dry grinding of gear teeth is surprising to see! German tech is the best in the world.
That's the type and size of equipment I was trained to repair. My journeyman card is for Machine Tool Repair. Found memories from Falk Corp.

Incredible engineering!
Enjoyed your video and gave it a Thumbs Up
Great people great work

How does the synchronization between the thread cutter and the spindle work? Is it handled by the computer with rotary encoders? Or is there some kind of linkage?
most likely axis interpolation between direct reading scales eg rotary encoder to linear scale.
When I was studying production engineering in the1980s CNC consisted of a DOS machine with 5.5" floppy discs controlling a punch cutter.
Accuracy 0.5 mm

Whats cool is somebody designed the machine to make the machines
What industry might those huge gears be for?
drawbridge mechanisms,mining machines etc.
They go on the outside of cement kilns, ball mills etc.
and what about windmills, waterturbines etc
The most gears you saw in the video are all made for the steel industry, the big once are used in gearboxes of hot rolling mills, some in converter tilting geraboxes etc.

It's looks good work.keep safe always friend 👍
Something so satisfying watching the shiny steel shaved off little by little.

Do you have any video from the gear manufacturing in China? Thank you
Where can I find so giant gears? In the power plants or inside the cargo ships ?

thanks! ill let the big "dick" mahoney know what you think
The dry cutting impress me the most. The coolant/lubricant would prolong the life of the cutting tool but somehow deemed unnecessary.
I saw various stage of large gear making back to front and the music excited me so much that I want to make my self one.
Where are these giant gears used ?

this could have a really informative video but instead you choose to show people ,,, instead of how the process is actually done ....!!!
It's a commercial advertising their services to clients. No money in showing a bunch of nobodies how they make a gear.

gears for adults. not as the small 2m gears that we had to hone by hand from the full in school.
Can anyone tell this huge gear is used for which industry /application?
Pls let me know name of the company manufacturing such huge gears
