Webinar: Advanced Mainshaft Bearing Solutions for Wind Turbines

Mainshaft bearings inside wind turbines are subjected to extremely harsh operating conditions that result in failure patterns which include surface-initiated fatigue, abrasive wear and uneven internal load distribution. This webinar will introduce you to the latest engineering advancements in spherical roller bearing design, including solutions that allow potentially damaging thrust to be safely transferred through the bearing to the housing support. The resulting reduction in torque, friction and heat significantly improves the overall efficiency of the system, thereby enabling the wind turbine to generate more power – more reliably!

1 Baby Steps in Wind Energy (August 2015)

The Department of Energy estimates that 4 million megawatts of potential power—four times the amount all U.S. power plants combined currently produce—exists in offshore wind energy. Construction of America’s first offshore wind turbines began in July. The wind farm, which is being constructed off the coast of Block Island, RI, will consist of five turbines. Together, they will produce 30 MW.

2 Modular Control Systems for Wind Energy (August 2016)

For a 5-megawatt wind turbine prototype, aerodyn employs the latest control and software technologies, including a comprehensive PC-based control solution and the new modular TwinCAT Wind Framework. The TwinCAT Wind Framework features the latest software engineering and Big Data applications to extend current Industry 4.0 concepts to the wind energy industry. The modular software supports, for example, the direct provision of sensor data to the operator’s database, and in general enables the easy adaption of the wind turbine operation management to future requirements.

3 Investigations of Bearing Failures Associated with White Etching Areas (WEAs) in Wind Turbine Gearboxes (March 2014)

A critical problem for wind turbine gearboxes is failure of rolling element bearings where axial cracks form on the inner rings. This article presents field experience from operating wind turbines that compares the performance of through-hardened and carburized materials. It reveals that through-hardened bearings develop WEA/WECs and fail with axial cracks, whereas carburized bearings do not. The field experience further shows that a carburized bearing with a core having low carbon content, high nickel content, greater compressive residual stresses, and a higher amount of retained austenite provides higher fracture resistance and makes carburized bearings more durable than through-hardened bearings in the wind turbine environment.

4 Wind Turbine Field and Test Rig Testing as Part of the Design Process for Gearboxes (September 2014)

The growth of worldwide energy consumption and emerging industrial markets demands an increase of renewable energy shares. The price pressure coming from coal, oil, nuclear and natural gas energy - combined with enormous worldwide production capacities for components of wind turbines - make wind energy a highly competitive market. The testing and validation of gearboxes within the test rig and the turbine environment attract a strong focus to the needs of the industry. The following contribution sums up the typical process requirements and provides examples for successful system and component verifications based on field measurements.

5 Michigan Eyes Investment at AWEA Small and Community Wind Conference (December 2009)

The first trade show dedicated specifically to small and community wind took place in Detroit, Michigan November 3–5. Denise Bode, American Wind Energy Association (AWEA) CEO, was pleased with the turnout for the event and the increasing potential for this segment of the wind energy market.

6 Wind Pushing Future of Mechanical Components (April 2015)

After a sluggish 2013, annual installations of new wind turbines grew by 44% in 2014, according to the Global Wind Energy Council. And while much of that growth has been in Asia— particularly China, which now leads the world with 114 GW of installed capacity—the USA, Europe, and the rest of the world expect steady growth for the next couple of years as well (Fig. 1).

7 Analyzing Wind Power (August 2016)

Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth’s surface, and rotation of the earth. Wind Turbines convert the kinetic energy in wind into mechanical power.

8 Momentum in Wind Power (April 2018)

Coming off of a stellar 2017 for the wind power industry, Wind Power 2018 is all about carrying that momentum forward.

10 FZG Gearboxes Lubricated with Different Formulations of Polyalphaolefin Wind Turbine Gear Oils (August 2016)

In order to analyze the different gear oils suitable for the lubrication of wind turbine gearboxes, five fully formulated ISO VG 320 gear oils were selected. In between the selected gear oils, four PAO base oils can be found: PAOR, PAOM, PAOC and PAOX. A mineral-based oil (MINR) was also included as reference.

11 Gear Lubrication: Long-Term Protection for Wind Turbines (April 2014)

The chemical and physical properties of gear oils may change, depending - more or less - upon their formulation and the environmental conditions under which they are used. This is why - after three years of use in a wind turbine - a gear oil was examined to determine if indeed changes were evident and if the protection of the gears and rolling bearings still met the same requirements as would be expected of fresh oil. Our findings revealed that the existing gear oil - as well as its ability to protect the gears and rolling bearings - had degraded very little compared to fresh oil.

12 AWEA to Wind Supporters--Do Not Panic (December 2010)

17 Premature Bearing Failures in Wind Gearboxes and White Etching Cracks (October 2014)

Wind turbine gearboxes are subjected to a wide variety of operating conditions, some of which may push the bearings beyond their limits. Damage may be done to the bearings, resulting in a specific premature failure mode known as white etching cracks (WEC), sometimes called brittle, short-life, early, abnormal or white structured flaking (WSF). Measures to make the bearings more robust in these operating conditions are discussed in this article.

24 How to Deal With Growing Pains (December 2018)

Wind turbines are getting bigger than ever, and the manufacturing infrastructure that facilitates their construction needs to start growing with them.

25 Global Industrial Outlook: Oil Slick, Currency Headwinds Worsen (April 2015)

End market conditions for the power transmission industry continue to worsen. With the Euro down 13% year to date and U.S. oil production surging we are seeing increasing headwinds, if not storm clouds, for the sector.

26 Global Industrial Outlook: Oil Slick, Currency Headwinds Challenge Growth (March 2015)

End market conditions for the power transmission industry have arguably worsened since our last column. In December we stated that with two armed conflicts underway impacting economic performance in Eastern Europe and the Middle East our stance was “Buy on the Sound of Cannons…. Selectively” while cautioning PTE readers not to be sanguine.

27 Solar Energy - The Alternative Alternative (October 2009)

While gear and bearing manufacturers engage in a wind energy arms race, the robotic automation industry has its sights set directly on the sun. Solar power—wind energy’s somewhat neglected step brother—has been gaining ground in alternative energy since 2001.

28 China! (April 2014)

Our last installment called out the likely headwinds from both the C.R.A.P. currencies (Canada, Russia, Australia and Latin America) and also weather impact. As companies start reporting in the coming weeks, expect first quarter results to be mildly impacted. This issue we take a closer look at China.

29 Finite Element Evaluation of Bearing Instrumentation Method (December 2014)

This paper presents an evaluation of measurements being taken on a 750 kW wind turbine gearbox being tested by the National Renewable Energy Laboratory (NREL). High-speed stage gears and bearings have been identified as critical components of the gearbox; during gearbox testing, these components were instrumented and tests were developed to evaluate loads on high-speed tapered roller bearings (TRBs). In this paper an advanced finite element-based contact modeling procedure has been applied to model the high-speed stage with the bearings fully modeled in order to evaluate strain levels. A major conclusion is that the strains of the slotted grooves are at such a level that they have acceptable signal-to-noise levels. This was verified by the results of the initial experiments presented here.

30 Plan Accordingly (April 2016)

Three upcoming shows cater to different areas of power transmission components and motion control technologies, including Windpower 2016, Powdermet 2016 and the Sensors Expo & Conference. All three exhibitions will offer the latest products, solutions and latest real world applications dedicated to wind energy, powder metal technologies and sensors. Here’s a quick rundown:

31 Global Industrial Outlook: Kind of Sluggish (August 2015)

We anticipate no substantive improvement in manufacturing activity. Not in the U.S. or internationally. If anything, headwinds may have become slightly more pronounced because a U.S. — Iran “deal” that everybody hates except a) the Iranian government and b) the Obama administration will result in the release of Iranian oil supply back onto the global market. Oil had rallied from about $50 to $60 over the past month (I like round numbers), but has since roundtripped. Expect further, deeper capital spending cuts in the U.S. oil sector to continue affecting demand for large capital equipment.

32 Bearing Protection Needed if Inverter-Duty Motors Are to Live up to their Name (August 2012)

All major manufacturers of 3-phase AC induction motors offer "inverter-duty" or "inverter-ready” models, but while these motors have inverter-rated insulation to protect the windings, the bearings--their most vulnerable parts--are too often ignored.

33 No Time to Kill for Barge Operation (August 2014)

The scene is serene and picturesque. Sunshine reflects off the light chop of the Ohio River, as a barge winds its way into view. While those driving along Louisville’s River Road may be inclined to reach for a camera to capture this idyllic scene, the mood at Nugent Sand Company is anything but tranquil.

34 A Recipe for Quality Big Bearings (June 2010)

Many power transmission components require a certain level of customization for each individual project. The big bearing market is no exception. Construction, mining, steel, marine and wind applications aren’t exactly areas where customers buy bearings in bulk.

35 DC Motor Protection (June 2013)
