A Practical Comparison of Planetary and Orbitless Gear-Heads.
Wind turbines are getting bigger than ever, and the manufacturing infrastructure that facilitates their construction needs to start growing with them.

Gearmotor manufacturers find new ways to push the envelope. (With Sidebar on new alternative to planetary gearboxes)
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.
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.
Coming off of a stellar 2017 for the wind power industry, Wind Power 2018 is all about carrying that momentum forward.
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 wasnââ‚¬â„¢t. Under its sleek shell, the car had a jet engine.
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 powerâ”wind energyâ™s somewhat neglected step brotherâ”has been gaining ground in alternative energy since 2001.
According to GTM Research and the Solar Energy Industries Association (SEIA), photovoltaic (PV) installations increased 41 percent from 2012 to 2013. Additionally, 410 MW of concentrated solar power came online in 2013. Solar was the second-largest source of new electricity generating capacity in the United States.

Prototype and Process Development Ensuring Stable Quality at the Highest Level
Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earthâ™s surface, and rotation of the earth. Wind Turbines convert the kinetic energy in wind into mechanical power.
The revolution goes by many names: machine-to-machine communication, smart manufacturing and the Industrial Internet, to name a few. In Europe, the prevailing term is Industry 4.0. In Germany, where that phrase was coined, the government is putting down â‚¬200 million to cultivate a lead in the industry. The McKinsey Global Institute estimates that its potential economic impact will be almost $4 trillion (or more) by 2025. Enthusiastic evangelists will tell you that the Industrial Internet is the most important advance in their industries that theyâ™ve seen in their decades-long careers.

A Q&A with N.K. Chinnusamy, president of Excel Gear of Roscoe, IL.
The Magnetic Gearing and Turbine Corp. (MGT), founded by Australian inventor Andrew French in 2000, manufactures injection molded gears and couplings based entirely on magnetic technology. The repulsive magnetic forces are used to transmit power without losing any energy, and drive shafts rotate completely independently of each other.
Th e signing of a contract for more than 5,000 sets of SKFâ™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 Companyâ™s (NGC) line of gearboxes for wind generation applications.
U.S. wind turbine growth puts a new spin on bearing manufacture.
The latest developments for wind turbines from Voith Wind rely on proven technologies.
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.

In recent years the estimation of gearbox power loss is attracting more interest â” especially in the wind turbine and automotive gearbox industry â” but also in industrial gearboxes where heat dissipation is a consideration as well. As new transmissions concepts are being researched to meet both ecological and commercial demands, a quick and reliable estimation of overall efficiency becomes inevitable in designing the optimal gearbox.
The Department of Energy estimates that 4 million megawatts of potential powerâ”four times the amount all U.S. power plants combined currently produceâ”exists in offshore wind energy. Construction of Americaâ™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.
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 Asiaâ” particularly China, which now leads the world with 114 GW of installed capacityâ”the USA, Europe, and the rest of the world expect steady growth for the next couple of years as well (Fig. 1).
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.
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.
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.
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 operatorâ™s database, and in general enables the easy adaption of the wind turbine operation management to future requirements.
