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 Documentation of Gearbox Reliability - An Upcoming Demand (June 2019)

The proof of the reliability of a gear drive is now an additional requirement. In Europe, the acceptance authorities for wind turbines are requesting a system reliability proof from gearbox manufacturers. The AGMA committee reviewing the AGMA 6006 standard for wind turbines is considering adding a chapter about design for reliability. However, reliability considerations are not new; NASA, for example, was in the 1980s using reliability concepts for gear drives.

3 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.

4 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).

5 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.

6 High-Capacity Bearings Carry the Load for Chinese Gearbox Manufacturer (December 2008)

Th e signing of a contract for more than 5,000 sets of SKF’s latest high-capacity cylindrical roller bearings (HCCRB) for wind turbines will impart added load-carrying capacity, more reliability and longer life to the Nanjing Gear Company’s (NGC) line of gearboxes for wind generation applications.

7 Cars with Jet Engines (June 2019)

In the late 1940s, the U.S. auto industry started an exciting experiment and spent decades on it. One result came in '63, when the Turbine was introduced by Chrysler Corp., now a part of Fiat Chrysler Automobiles (FCA). In appearance, the two-door, four-passenger car looked like a regular car, but it wasn’t. Under its sleek shell, the car had a jet engine.

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.

9 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.

10 Capacity--And the Lack of It--Rules (February 2008)

U.S. wind turbine growth puts a new spin on bearing manufacture.

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

Despite posting its slowest quarter since early 2007, AWEA remains optimistic that the wind industry can and will work successfully with the revolving doors in Washington.

12 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.

13 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.

14 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.
