After getting positive feedback on changes made to the show last year, AWEA Wind Power is doubling down and taking their ongoing transformation even further.
The first trade show dedicated specifically to small and community wind took place in Detroit, Michigan November 3â“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.
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.
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).
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.
Wind is the talk of the town. It has become especially relevant to the power transmission community where bearings, gears, couplings, motors and gearboxes are providing the equipment for this thriving alternative energy industry. It comes as no surprise that the Windpower 2009 Conference and Exhibition, arriving in Chicago from May 4â“7, will be the largest gathering of wind energy professionals and technologies to date.

A thermo-mechanical model of a splash lubricated one-stage gear unit is presented. This system corresponds to a first step towards the design of a hybrid vehicle gearbox that can operate up to 40,000 rpm on its primary shaft. The numerical model is based on the thermal network method and takes into account power losses due to teeth friction, rolling-elements bearings and oil churning. Some calculations underline that oil churning causes a high amount of power loss. A simple method to reduce this source of power losses is presented, and its influence on the gear unit efficiency and its thermal capacity is computed.

When trying to find a new bonding material dispense system, one manufacturer tested a series of pumps â” all of which leaked due to the abrasiveness of the bonding material. The manufacturer also had been attempting to manage shot size manually with their previous system, and was not able to keep dispense consistent. The company searched for a system that could accurately dispense programmed shot sizes while also eliminating the leaking issues they had experienced with previous pumps. Graco provided a Check-Mate pump with SmartWare software, and the manufacturer is now able to automatically dispense shots of bonding material as small as one ounce without leaks.

Increasing power density and improving cylinder lifespan are key issues.
Power density is a key factor in gear design. Increasing the power density enables engineers to use smaller gears for their applications which lead to smaller and lighter gear boxes. The benefit for example for the automotive industry is less moving load in the vehicles and therefor a reduction of fuel consumption and subsequently a reduction of CO2 emission. The limiting factor for the increase in power density of gears is the material strength in regard to the critical failure mode.

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

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.
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.
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.

A Q&A with N.K. Chinnusamy, president of Excel Gear of Roscoe, IL.
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.
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.
