Normal gearbox is more quiet and sound is high, like whistling. Like electric forklift, you hear mostly engine. Damaged bearing is loud, sound has much lower frequency.
The bearings in the generators we service in NZ are not huge however they are some of the largest rolling ball elements made (6336 C3) They are in the 2MW ABB machines. Bearing is small enough i can lift it myself and sit it on the bearing heater and then lift it over to fit it. Guessing 30kg.

This is terrifying. I’m already scared of wind turbines, but am obsessed with them, but seeing them from the outside is enough. But being inside it hearing it starting up and all the sounds and everything… holy crap being inside those is one of my worst fears. Irrational fears, that is. Tall ceilings and large spaces or terrifying 😮💨
@@frosty6960 Idk, I have a fear of large objects(I forgot what the phobia name is lol) or large empty spaces. It just seems eerie, like something is out of place. Oddly enough, whenever I drive by one I can’t take my eyes off of it. They’re scary but mesmerizing in way?? I can’t explain it
Fascinating!! i guess the low rotation speed is being geared up to high speed rotation of some small generator in the top that is generating relatively DC high voltage ? or is it AC? whats the frequency/rotation speed of the generator/dynamo?
Is that a v47/52? Keep pumping the generator grease. Will run for another 6 months. I changed generators bearing on a v47 in turbine before. It's an awkward job .
😅 that's exactly what we did on this V90.... but at some Point the condition is going pretty fast, pretty bad. There are definitely way better jobs on the Turbine 😄
Not on this particular type of Turbine. On almost every newer one it would trigger some kind of alarm like "generator Bearing A excessive vibration" which is been measured by the condition monitoring system. This system is working with acceleration sensors on various spots. Enercon and Siemens DD Turbines are able to detect unusual and loud sounds via various microphones.
The first warning is a large pillar of smoke and this may be followed by an audible tone such as a shreik, a squeel, and in some models a series of loud bangs. At this time you should switch the appliance off.
In this Case it was discovered during an routine Inspection. On newer Turbines there is mostly a condition monitoring system, that measures constantly the Conditions of the critical Bearings with acceleration Sensors.
This depends on the Type of Turbine and is between 1kW, up to ~15kW. In Production the own consumption is higher due to the Converter in operation, but this Energy is directly supplied by the own production. The consumption per Turbine per Year (means the periods there is no wind and the Aux systems of the Turbine have to be feeded by the Grid) depends highly on type and Wind conditions and vary between several 100 kWh up to 20 MWh, or In other Words between a shed and 5 Family houses. This may sound bad, but a Turbine is producing thousands of times the Energy which it consumes a year.
Esta turbina tiene un motor hidrauli o de 80kvas el convertidor para acoplar unos picos de 20 kvas odo depende del viento si es 3m/s acoplar y desacopla consume mucho
It was windy I guess :) There may be a gearbox between the rotor and the generator, so the RPMs of the generator is way higher than the blades we see outside. It depends on the model of turbine.
The Bearing Was about 10 Jears old and did several billion rounds, it's OK for retirement. These can run up to several months with a damage before the mandatory exchange of the Bearing.
@@saasch_baasch With respect, 10yrs isn't that long! Is it a design problem? I have no idea as to how long the bearings last in a 777 engine, but hopefully longer than 10yrs. From my perspective it's the 'perceived' difficulty factor in repairing the gearbox. Can the gearbox be removed /replaced without disturbing the blades?
I am not working for MTU or Pratt and Whitney, but I am sure that the design requirements and the kind of Bearings used inside a PW4000 Turbine of a 777 is absolutely and totally different. Just imagine what could happen after a failure... Boeing: several hundred People in danger of live... Windturbine: some minor Power less in the Grid... I guess that the Bearings inside a PW4000 are hydrostatic and high performance Bearings, which are absolutely non comparable to the Windturbine "simple" ball Bearings. 10 Jears may sound short, but just do a small calculation: the average RPM of the Bearing is 1000 1/min. * 60 minutes * 24 hours * 365 days * 10 jears.... about 5 billion rounds. Do the same for the tire bearings on your car: around 750 1/min (17" tires and 60 kph average) * 5000 hours (that's 300,000 km at 60kph average) this is just 3,8 million rounds, that's factor of 1400, so this 10 jear old Windturbine is like a car with 420 million kilometers on the dashboard.... of course, the conditions of a car and a Windturbine different, but this is just an example of how much operating hours Windturbines do have after a short period of time. The Change of a generator Bearing can be done by two men, takes about 2 days (varying) and doesn't need a huge crane. Gearboxes may be changed without disassembling the Blades on most Turbines.
Just a point from my side. Bearing in a 777 engine eg are getting changed after shorter period of time, as it’s mandatory for maintenance. A former colleague was working for a big plane turbine producer in Switzerland.
@@raysaunders5914 3 years late, but generally the bearings in a 777 engine will last considerably less than 10 years. Totally depends on how often the plane was used, but once the engines rated hours are up it comes apart for an overhaul and the bearings are usually done. 15,000-60,000hrs depending on the engine

I don't know why it jusy occurred to me but the thrust bearings on these must be absolutely, positively MASSIVE.

Most likely a crossed roller bearing. It takes both the radial and thrust loads.

What was the reason for starting it up again with a damaged bearing? Or was this the first time someone noticed a defective bearing?
Except for the big bell like clang it sounds almost normal. However, a main bearing element that is damaged has the potential for a big problem
Thanks to microphone auto processing this may sound something like normal, but in real this is anything like normal 😉

Do these implements experience current through bearings that exacerbate wear through high voltage pitting ?
Or is that managed in some way?

In this Case it was discovered during an routine Inspection. On newer Turbines there is mostly a condition monitoring system, that measures constantly the Conditions of the critical Bearings with acceleration Sensors.
How much power do turbines consume when idle? Do you know how much does 1 consume per year?

And I thought the bearings I helped replace on a timesaver (industrial conveyor fed belt sander) were bad! The shafts were quite wallered out too.

There may be a gearbox between the rotor and the generator, so the RPMs of the generator is way higher than the blades we see outside.
