I like how the video only shows the managers names and not the engineers and workers. It clearly shows the mentality of the company.
Who else thought they were going to see a video on it actually being made?
That is what I thought it was going to be as well.
I was hoping.
The largest wind turbine in the world. Very cool. A slam dunk for an interesting video one might think. And yet, no. Somebody seems to have let the marketing department go nuts and turn it in to a friggin commercial. Very disappointing.
I'm doing a COMSOL project to model vibrations in a 2MW wind turbine gearbox and found this video in researching how it actually works. This is so impressive! I had no idea how huge the gearbox would be!
Less sales pitch and self congratulation but more technical detail would have made a better video.
u b rite !!
Made by manager for managers! 👎🏼
Apparently you don't understand the nature of "green energy." It's not about practicality and improving the environment, it's about money and self congratulation.
'Feeling' like you made a difference is more politically useful than 'actually' making one. Otherwise, we'd build nuclear reactors. Just one would replace hundreds of these and work 24/7.
Fr. Why does youtube keep suggesting commercials
@@matthewmcclain1316 the sweet managerial talk is the soft hand gently caressing your rear end, only for you to find out later that they were just interested in your wallet and give anybody the same BS.
Damn 8 MW!!! Wind turbines are sure getting big. I guess this is driven by the efficiency of scale. This is the kind of new technology we need for our new green future. This is very encouraging. As a retired mechanical engineer, I wish I could have been involved in a project like this.
GE is now testing a 12 MW turbine in Denmark. I hear a 15 MW is in the design stages. There is a race to make them bigger, more efficient and cheaper. It leaves me in awe where we are headed in the next few years and comming decades.
Deluxe sauce, ABSOLUTELY! I was going to say that they should have focused more on the actual machines, and not turned the entire vid into a PR/Sales vid for the companies.
Amazing. For my undergraduate degree I worked on research into wind turbine gearbox planet bearings and I was only looking at a 750kW turbine (the research turbine of the NREL). It's interesting that you chose a design with two planetary gearing stages, since planetary bearings and gears can't be replaced in situ on the turbine (as far as I know). You must be very confident with the design, particularly with the very high loads which makes it especially impressive to me.
I'm feeling proud that I'm a part of winergy and Flender. #wemovetheworld
That's the biggest planetary gear set I've ever seen. Imagine the thrust washers in that bad boy 👍
This is really cool!! Especially since the gears are spinning 24/7 non stop
False, you need enough wind.. If only they could run 24/7..
One can only watch and listen with awe at this masterpiece of engineering. Unlike a simple work of art whose superficial surface finish is always seen by the human eye and which the public seem to be so emotional about and appreciate it through hanging it and showing it in public places, homes and theatres, such magnificent engineering, in contrast to pieces of art, is far away from the public eye, working in silence and unseen handling the energy through one end and transforming its to a more convenient manner at the other end to ensure that the magnetic fields are cut at a suitable rate of change to make alternators more convenient and efficient. It is even more magnificent to think that all this material has to work continuously for many many years, guaranteed to service the modern, tangible modern comforts in homes, hospitals, industry, transport systems and many more issues of our infrastructure. Few people in the social professions can appreciate the responsibility of guaranteeing such a product and prefer to work in the emotional classical professions which never guarantee their work. It seems that evolution takes a long time to create professions which provide real tangible comforts in a modern home and any country needs careful consideration of its educational system to ensure that children do not opt to chose the classical professions which are so emotional in their contents and guarantee nothing as most nations have such professions is great numbers but do not seem to reach the social and technical advancements which is reached by those countries where the logical and factual talents are encouraged in children to produce a product that is guaranteed to serve society and give all the tangible comforts it needs rather than the emotional requirements needed by many people. It is indeed a difficult decision for any country to take as to what type of education should be made compulsory for children such that they do not grow up to having to many dreams which cannot be achieved and for them to work on those dreams which they can achieve through understanding the beauty of the universe and its hidden wonders rather than philosophical emotional concepts, which never caused any nation to provide itself with tangible comforts in homes and hospitals and the social living quarters of any nation.
Engineer dedicated to and passionate about innovation, science, development and simulation speaking.
You don't need to bash other people's dedications/interestes/professions/passions to get your point across.
MINT is marvelous, but certainly not everything and not worth living if it was the only thing in the world.
Correct
Still needs improvement big time. All in their industry knows that the weak point is the gearboxes in a windmill. Waiting for the 12MW units.
i understand the diameter of the gear but the depth seems interesting considering the materials
Lovely piece of work.
Great product FLENDER GEARBOXES. Now working as a technical engineering consultant. I help customers understand the correlation between the component in gearboxes, the MRO-loop, FFT spectrum, aSKF value, the selected oil and what end-users can easily change to improve MTBF and reliability.
To all concerned in this project please take a bow, 11,000 homes!! That's a huge number and
all that energy from the wind.
I am sure this company is doing excellent job but this video has turned out to be a corporate video where they talk of cost schedule quality.They should have focussed on actual product mfg process.My opinion.
“The energy history of the future” how do people come up with statements like these?
Good job guys. Keep it up
Very interesting Great video 📹 thank you for Sharing Australia 🌏
Too much talk, not enough of actual manufacturing technique.
Make it bigger, what a breakthrough.
Very nice! I like it!
I love this stuff.
With losses, this is approximately 12,100 horsepower. At 9 RPM, that's close to 7,043,199 foot pounds of torque. I can definitely see why they chose the 2 stage planetary design.
Amazing accomplishments!
Hey WinergyGroup: make a video about the goddamn gears please -- I don't care about the engineers. Show us the manufacturing process.
*Impressive machine.* The wind turbines are starting to be more and more powerful.
Every turn of this wind turbine is going to produce sustainable and clean energy, which means more of the clean air for all of us. We can be happy about that !
Nothing beats an Eickhoff Gearbox. In a Pinwheel as well as in a Shearer.
Can you please guide me about the gearbox , we are working on 1.2 mw wind turbine
winergy gear box are good quality , another supplier was hansen i believe which my company suzlon bought...
I have this gearbox in my truck :)
I put one in my wife's watch.
It's a beautiful thing
These guys are going even bigger with floating colossal wind turbines.I think we should be thinking atmospheric from what the statement implys about structure and also I think it was said maybe as high as the troposhere.
Freeken Hanif!!!! Windpower is a small world!!!!
Hmmm a lot of not correct information, it is neither the biggest, most powerful turbine or gearbox. Since the MHI Vestas offshore Wind A/S. V164. is aporved for 9,5MW . and alread in Jan 2017 when this video was released. MHI Vestas had a 8,4 MW aproved
This video is about the largest gearbox as per Jan 2017 (and the video was created even earlier than that). You are right that the V164 reached 8MW capacity since 2013 and later greater capacities. However with a smaller gearbox. In fact most wind turbine manufacturers, including Vestas, want to eliminate the use of the gearbox through direct drive and more sophisticated and more powerful power electronics.
You can find something like this on the Avasva page. Full step-by-step instructions right on your desk.
5:24 The SIZE of that gearset!
I wonder what is the price range of this type of machinery?
couple hundred thousand im betting, and since the gearboxes tend to fail the most often in wind turbines, at least they can make money off of recurring purchases.
Wie viel Leistung geht in diesem Getriebe verloren bei Nennlast? Wird das Getriebe irgendwie aktiv gekühlt?
Bei Nennlast gehen innerhalb des Getriebes weniger als 1,2 % der Leistung
verloren. Um diese Verlustleistung abzuführen ist das Getriebe mit einer
separaten Ölanlage, welche u.a. aus Pumpen und einem Ölkühler besteht,
verbunden.
8 MW at 89 rpm, wow there must be a lot of torque on the input to the gearbox.....and the tower holding the whole lot up.
No it's a lot of hot air, wind and solar are about hot air and liberals.
Too many people bragging on themselves and not enough about the manufacture of the product!!! Dislike.
Video should be named " talking about it, not showing it"
What gear cutting and grinding machines were used to create these very large gears?
That looks impressive, until you realise it will be put igh up on a slender column above the sea.
Hello, i want to know How to monitor the grease level inside the gear box?
Good thing most of energy blows between blades of 509 year old leonardo design being so tall leverage blows them down
The best part of the video is where you guys say the same thing over and over and over again in slightly different variations. Actually that's the whole video.
It's actually a sales job.
Why do they don’t mount the gearbox and generator on the base of the tower instead of on the nacelle on the top ? Just use and angular gear on the top to transmit the power to the base. Installation and maintenance cost would be half..or less
6:16 - I see Antonio Banderas turned up to give us the low down on this box o' gears!
German engineer's looks and speeks like Terminators from skynet...
Who shot this? Helen Keller?
Counter rotation in parallel we get more power and energy
I'm all for renewable energies but you guys need a new camera guy. He seemed more interested in recording the backgrounds and not who was talking. Plus it would be great to see more actual manufacturing and generally more science behind the scenes.
Gearbox looks like gears in a automatic transmission
I m a mechanical engineer & I would like to work with you all.
This transmission is surprisingly simple in concept. It just has huge requirements on material strength calculations, manufacture precision and stuff like that. Automatic transmission in a car on the other hand is the worst possible nightmare. :D :D
Same concept as an automatic transmission, just scaled up by around 800 times.
As Mandy Rice Davis or Christing Keeler rather accurately quipped "well they would say that would'nt they!"
4:50 It is all nice and well, but does it fit in my Toyota hybrid? :)
Why do they use blades like that on smaller turbines, why don't they use blades (barrel style) like an air handler uses?
The Winergy 6MW gearbox has reliability issues, I have seen many replaced (as well as other manufacturer gbx's in this class). They need to build the 8MW gearbox to try and stay in the game but I highly doubt it will be any better.. Turbines are getting bigger, rotor speeds are going down due to blade limitations. Gearboxed turbines will have a slow death, just a matter of time. Physics will win this battle.
How can a gearbox be powerful ?
It's a transmission device ,not a producing power device.
Should have said it's strong, but that doesn't have the same emotive feel.
What torque are these things generating at peak?
+850.000 Nm..
It powers 11000 homes in ideal conditions and power none in high or no wind.
Green energy needs more development.
Agreed. You just were watching this "development". XD
jeabo0adhd
No matter how much development there is the fundemental drawbacks will still remain. Variable and to a point upredictable source of energy. A cube law relationship between wind speed and power output give an unstable genration, and the need for back up sources to provide security of power, not to mention the cost of subsidies.
Forget it, we gave up on wind power, quite rightly, decades ago.
Best part is that there were no meathead Americans or American flags hanging all over the factory. Awesome!
couple people looked experienced...
8mw, that's cute
Disappointing. Thought information would be shown. instead sit through an ad to be shown a company promotion.
if you power to and from a battery, you get rid of most complexity
Starts at 5:00 ends at 6:00
Vesta!!
At 0:35 LCOE = Life cycle cost of Energy????? Should it be Levelized Cost of Energy??
whats the energy cost of making one of these... will it ever make it back to justify its existance?
@saladdogger No it will NOT! It would need to run, with the wind blowing @ 35 MPH continuously with no slowdown in wind for about 30 years!! and wind doesn't do that!
Build Nuclear!!
@@weatherphobia nuclear is great, but how come we are moulding the spent waste reactor fuel into missile heads, bullets, and lawn darts instead of using scavenger reactors to burn it?
Those gears and planetaries may be "huge" but the actual gear teeth and thickness of parts like the ring gears are NOT "proportional" to the torque loads they'll be subjected to. And without "light" and "thin" oil and very complex and very "energy inefficient" lube/filtration/cooling systems those things are destined to fail. And that's a big problem on a WIND TURBINE since the "rotor" is "upwind" from the nacelle and there isn't much AIRFLOW OVER/THROUGH/AROUND THE NACELLE to use for COOLING THAT LUBE OIL. ALL of the "foreign" manufacturers of wind turbines that have exported their machines to the U.S. have had GEARBOX PROBLEMS at anywhere from a FEW MONTHS to a FEW YEARS of "constant operation" because there IS NO SUCH THING AS "CONSTANT OPERATION FOR YEARS" CAPABILITY FOR ANY MACHINE AND NO MACHINE IS DESIGNED FOR IT. AND "CONTINUOUS USE" is FAR BETTER AND MORE DESIRABLE than the REALITY machines like wind turbines have to survive which is SHORT-TERM OPERATION AND LOTS OF "COLD" AND "DRY" STARTS. "Capacity factor" is thrown around as a "metric" of what wind turbines are supposed to be able to do as far as "efficiency" but that's always bullshit.
First of all, not even "60%" of available "wind energy" can be "harnessed" by a wind turbine because "WIND RESISTANCE INCREASES WITH WIND SPEED". The higher the wind speed the less efficient wind turbines are even within their relatively small "window" of actual generating "capability" which is only single-digit "mph" in size. Over 12 mph at the NACELLE LEVEL and they're shutting down. And at 5 mph that's just enough wind speed to "break even" AFTER the electricity necessary to OPERATE THE TURBINE since the LAST GENERATION "EVENT" has been "made up". And oh yes, they are NET CONSUMERS OF ELECTRICITY AND A LOT OF IT WHEN THE WIND ISN'T BLOWING. Especially those in "cold" climates that need GEARBOX OIL HEATERS AND PRE-LUBE PUMPS ALONG WITH THEIR NORMAL ELECTRICALLY-POWERED HYDRAULIC SYSTEMS THAT ROTATE THE NACELLE AND BLADES TO THE PROPER POSITION FOR "STARTUP".
And the fact is that wind is rarely "just right" for "profitable" operation. They don't "fire them up" if the wind is "freshening" and heading toward a "high wind" period where they're unable to operate because "loss of control" is a real threat and since WIND BLOWS DUE TO CHANGES IN "BAROMETRIC PRESSURE" AS AIR MOVES FROM AREAS OF "HIGH PRESSURE" TOWARD AREAS OF "LOW PRESSURE" AND "LOW PRESSURE AREAS" ARE PRETTY MUCH ALWAYS ASSOCIATED WITH "STORMS" AND OTHER "UNSTABLE" TO "SEVERE" WEATHER AND "IDEAL WIND" ON THE GROUND CAN BE FAR TOO HIGH FOR THEM TO OPERATE SEVERAL HUNDRED FEET OFF THE GROUND, EVEN WHEN THEY'RE "TURNING" AND ESPECIALLY IN "HIGH WIND" THEY'RE NOT ALWAYS "GENERATING". THEY "FEATHER" THE BLADES TO CONTROL SPEED SINCE NO "BRAKE" EXISTS THAT CAN STOP/HOLD THEM IF THE "RIGHT" WIND HITS THEM HARD ENOUGH AND THEY ALWAYS HAVE TO "FACE" THE WIND OR RISK HAVING A "SIDE WIND" BREAK THINGS PUSHING ON JUST TWO BLADES AT ONCE.
And since "society" has changed "radically" since the last big "wind energy" experiment in the 1970s when a LOT more "moms" stayed home and household energy use was highest during the day while "mom" cooked and baked and cleaned and did laundry and watched TV while Dad was at work where "business" energy use was also "peaked" during the day and now "peak usage" is "split" between a few hours in the early morning when people are getting up and getting ready for work and furnaces/air conditioners are "cranked up" after being "turned down" all night AND another few hours in the "late evening" when that's all being "reversed" and "housework" is getting done before and after work and people's high-stress/high-speed working lives have them staying home and in the house a lot more on weekends when they just "veg out" and rest, peak usage is now when WIND ENERGY POTENTIAL is at its absolute LOWEST. The weather is always "calmest" during the "dark" hours of the day and when it IS windy during the "dark" hours its usually "stormy" and the wind is short-lived and too strong or unstable or unpredictable to be of any use.
The bottom line is that over their lifetimes, no "generator" is EVER going to "make money" any more than any other mechanical machine that turns "energy" into "power" for use by OTHER MACHINES/SYSTEMS can "make money". Least of all one that is running "continuously" 24-7-365 just to be on "standby" to be actually WORKING a small fraction of its "service life". People who bitch and moan about internal combustion engines and people letting their cars "warm up" in the winter and/or "cool down" in the summer before getting in and driving them places have no damned clue that when it comes to "powerplants" they don't come ANY LESS "ENERGY EFFICIENT" THAN WIND TURBINES. Especially when the electrical "energy" the DO generate when they're actually "working" is DIRECT CURRENT POWER that has to be "inverted" to produce AC power "for the grid" while it CONSUMES AC POWER when its NOT "WORKING".
And that is the OTHER reality. AC current MUST BE at the EXACT RIGHT VOLTAGE AND HERTZ (CYCLES PER SECOND) AND "2-PHASE" (3-PHASE AC IS ACTUALLY TWO LEGS OF ONE "SERVICE" AND ONE LEG OF A SECOND "SERVICE" AT THE "CONSUMER" LEVEL WHICH IS WHY 3-PHASE IS SO EXPENSIVE TO "ADD" TO AN EXISTING 2-PHASE SERVICE) AND THERE IS NO "POWER CONVERSION" LESS "EFFICIENT" THAN "INVERTING" DC TO PRODUCE AC POWER. MOST OF THE ENERGY IS LOST TO HEAT BECAUSE "INVERSION" ACTUALLY REQUIRES "INDUCTION" AND "SHUNTING" OF EXCESS DC CURRENT AS A DIRECT-CURRENT "FLOW" IS "STEPPED UP" BY A "COIL" AND THEN "CHOPPED UP" INTO "3-PHASE AC" BY "SWITCHING" THAT "STEPPED UP" CURRENT ON AND OFF "12O TIMES PER SECOND".
A car's "alternator" produces ACTUAL "3-phase" AC power and then "rectifies" that 3-phase AC current sending each "phase" through a simple diode that prevents it from "reversing" back into the stator winding it was induced in which would prevent that winding from getting MORE DC electricity from the VOLTAGE REGULATOR that "excites" the alternator stator windings "alternately" to produce those 3 phases and uses voltage to switch on/off that excitation current. Because its a relatively low AC output of "only" 90 volts or so and a relatively low amperage "per phase" and solid-state electronic voltage regulators now exist, a vehicle alternator at best can operate "continuously" at maybe 2/3 of its rated capacity. And internal combustion engines with spark ignition and electronically-controlled diesels need more "juice" the faster they run and the harder they work. And there's a BATTERY to act as a "storage reservoir" AND built-in "load" (due to internal resistance) on the charging system and the ALTERNATOR NEEDS ELECTRICITY TO PRODUCE ELECTRICITY. And rectification is "easy" and "energy efficient" compared to "inversion".
POWER PLANT ENGINES RUN AT SET RPM TO PRODUCE THEIR "RATED POWER" AT A SPECIFIC CYCLES PER SECOND USING ACTUAL "ALTERNATORS" BECAUSE AS LONG AS YOU CAN CONTROL SPEED AND EXCITATION YOU CAN CONTROL "OUTPUT" IN "VOLTS" AND MATCH THE "GRID CURRENT". BUT WIND GENERATORS CAN'T ACCURATELY AND PRECISELY "CONTROL" SPEED AND THEIR EXCITATION CURRENT IS "AC" AND TOO HIGH TO BE "SWITCHED" ACCURATELY/PRECISELY TO BE "CONSTANT VOLTAGE" GENERATORS SO INSTEAD THEY'RE JUST VERY EXPENSIVE AND INEFFICIENT DC GENERATORS SINCE EVEN DC GENERATORS IDEALLY RUN AT A "STEADY" AND PRE-DETERMINED SPEED TO PRODUCE "CONSTANT VOLTAGE" BUT BEING "DC" AND BEING ABLE TO "CONTINUOUSLY" EXCITE THEIR FIELDS WITH A STEAD FLOW OF CURRENT AT A MUCH LOWER AMPERAGE BECAUSE THEY'RE NOT "SWITCHING" ON AND OFF, THEY'RE STILL VERY "EFFICIENT" COMPARED TO WIND GENERATORS.
The OTHER reason wind turbines must be DC and the current "inverted" to go "on the grid" where that's even possible - there's a big push for "HVDC" or "High Voltage Direct Current" lines in the U.S. in several areas and coincidentally all of those DIRECT CURRENT "TRANSMISSION LINES" IN A COUNTRY WHERE ALL "GRID POWER" IS ALTERNATING CURRENT TEND TO BE "PROPOSED" IN AREAS AND ALONG ROUTES WITH "WIND FARMS WITHIN 10-20 MILES OF THEM AND THEY ALL LEAD TO AREAS OF THE COUNTRY WHERE "HYDROPOWER" IS A MAJOR SOURCE OF "GRID ELECTRICITY" AND WHERE "INVERTERS" SUFFICIENTLY LARGE TO HANDLE "INVERTING" SO-CALLED "HVDC" ALREADY EXIST SINCE "HYDRO POWER" IS ALSO PRODUCED BY DC GENERATORS BECAUSE HYDROELECTRIC POWERPLANTS CAN'T CONTROL "GENERATOR SPEED" ACCURATELY/PRECISELY ENOUGH TO PRODUCE AC CURRENT AT THE GENERATOR EITHER AND LEAST OF ALL IN A "GENERATOR HOUSE" WITH SEVERAL GENERATORS WORKING "SIDE BY SIDE" BUT COMPLETELY INDEPENDENTLY OF EACH OTHER) - is that to put a "powerplant" on the grid its OUTPUT VOLTAGE AND HERTZ HAS TO PRECISELY MATCH "LINE VOLTAGE/HERTZ" WHEN THAT "SWITCH" IS CLOSED OR THE MASSIVE AMOUNT OF ELECTRICAL POWER "IN THE GRID" WILL LITERALLY STOP ANY "POWER PLANT" OPERATING ALONE DEAD OR DESTROY BIG, EXPENSIVE PARTS TRYING. THERE CAN BE MILLIONS OF "HORSEPOWER" IN THE "GRID" AND SOMETHING LIKE A "SMALL TOWN" DIESEL/NATURAL-GAS GENERATOR OF SAY....7770 HP AT 140 RPM FROM AN 83,000 cubic inch engine will literally be "killed" if its brought "online" in a "peak load" situation for "load balancing" during a high-use period. And since you're talking about several dozen TONS of steel and iron going "around and around" in that "little" gen-set engine stopping in an instant, "killed" is the correct term for what happens to the "little" powerplant.
No wind turbine comes anywhere NEAR making that much "horsepower" all by its lonesome despite having as much or more "rotating mass" spinning away on it as its generating. So you can IMAGINE what would happen if a WIND TURBINE were brought "online" even if were POSSIBLE for one to produce "high-voltage AC" sufficient to go "on the grid" directly. I guarantee the blades would probably NOT break off the hub or at least not "instantly" either the hub would twist off the gen shaft or the gen would twist out of the nacelle.
it seems to me that if you pumped air or a fluid like water with a variable displacement pump and put the generator and associated stuff on the ground you do not even need a gearbox . why go to all that trouble to do all that precision machining?
got a video link? also hydraulics at those power levels tends to break quite spectacularly and have a lot of losses versus direct mechanical leverage
Is the gearbox just to step down the torque? cause i don't get how a gearbox is useless in an electric car but its useful in a wind turbine?
the electromagnets that push and pull the spinning part of the electric motor work best when the two opposing fields are slowly moving or stationary (on a CAR).
the giant blades only spin the shaft maybe around 20 more or less RPMs, so it needs to be brought to a speed that a generator motor will work at. generators use fast moving magnets to generate an electric current in a coil of wire, which creates a flow of electricity in that wire and thus an opposing electromagnet, again. that electric flow from the generator can be low or high voltage depending on how many wraps of wire the generator uses, and the current can be high or low depending on that and some other stuff like how hard the blades are pushing the magnets through the generator's induced magnetic fields.
Turning rotational energy into electricity because of how magnets cause electricity to flow through a wire, OR pushing your car along because of how electromagnets push against other magnets.
They probably could have saved a lot of trouble by just designing a molten salt reactor instead. Selling byproducts of the nuclear reaction and electrical production could pay for the cost of running the unit and electricity costs could be tiny or zero, depending on how well the other products are sold.
Nothing quite like tooting one's own horn.
Wind energy has been drastically recind in alternative energetic sources
Why
Phesiablites audit must
With a savonius sailboat.
Correct Title should be: "TALKING ABOUT Building the world’s most powerful gearbox for wind turbines - the Winergy 8 MW gearbox" Engineers come to see how thngs are made not listen to people talk about making things. There were a couple brief glimpses of the cool stuff but far too much talking..
But will it fit in my Honda?
I think your Honda can fit itside it.
Using synthetic lubes for the gear box
funny, dont worry. The 18650 will help keep energy costs down 😁😊🤣
More tech, less talking! ffs...
Ich glaub ich hab ein 980er Planetenrad entdeckt 😂🤦🏻♂️
Can anyone prove the energy it takes to make this product is replaced over the life of the unit? This should also include the energy it takes to decommission the unit. Wind is not the answer
Vestas be like "8MW? Hold my beer.."
Winergys gearboxes are propably the worst ones sadly. The bearings in these boxes just dont seem to last. But it keeps me busy working so go on😂
I am a big fan of wind energy but the American corporate vid producer here has rather let down their client.
Terrible title as gear boxes don't produce power.
Yo, guys, I don't think this will fit in my honda. :(
I bet 2 Hondas could fit in this LMAO
how much weight?
The gearbox has a weight of 80 tons. Including the coupling flange 86 tons. The input torque is roundabout 10,000,000 Nm
WinergyGroup thank you so much for your kindly reply
That is an incredible amount of torque, I'm still battling wrapping my mind around it.
pffff the amount of torque is insane hahaha
10.000.000 Nm holy moly!!
zwingt doch bitte nicht die Leute Englisch zu sprechen, klingt schrecklich
Recht hat er. Die wenigsten Deutsche versuchen englisch richtig zu betonen. Ist ja nicht schwer, aber ungewohnt.
i don't believe 11000 homes. 8 mw / 11000 is only 727 watts/ home.( less than 1 hp) and 8 mw is only about 30% of the time if that. ave output would be way less.
8MW is less than 11k hp .... a geared turbofan does the same job at 100k hp , in a very compact and lightweight assembly... www.popularmechanics.com/flight/news/a28082/rolls-royce-record-most-powerful-turbofan-gearbox-aircraft-engine/
so whats your point
Apples and oranges.
This disappointing little ditty doesn't pass muster, there is too much waffle from a load of old gasbags and barely a gear in sight. Rummy and vexatious.
Fine words don’t build grand castles.
VESTAS WIND ALL THE WAY!!
not hardly. let's see you say that when they're all down because no wind is blowing!!
The Zf gearbox is better
More "powerful" than the F35? Don't think so.
The F35 is a joke lol
