Blade bearings might not exactly be the most expensive components in a wind turbine, but damage to this fundamental part of the system can result in considerable downtimes and costs. By designing and testing blade bearings under realistic conditions reliable operation of future turbines shall be improved. In the HAPT research project (short for “Highly…

Wind power generation has been a proven technology and emits no carbon dioxide. It has gained widespread acceptance as the cleanest and most environmentally friendly form of energy. The increasing reliability of the system, especially the wind turbine, while reducing the operating expenditure remains a challenge in the wind power industry.

A flexible-pin gearbox that improves load sharing between the various gear elements makes it valuable for high peak load applications, such as wind and tidal-power turbines.

Large electric motor, wind generators and industrial gearbox repair services available for customers in the Pacific Northwest The Timken Company has opened a 70,000-square-foot, state-of-the-art motor and gearbox repair facility adjacent to its existing service center in Pasco, Wash. Built to enhance service to Timken Power Systems’ (TPS) customer base throughout the Pacific Northwest, the…

If wind turbines are to be built larger, their designers will have to think differently about building larger components. An inventor in Dallas wants to assist with a recent design for a pitch drive could take weight off a rotor and a turbine’s main bearing. The clever cam-activated mechanism turns a ring gear by “walking”…

RECENT PERFORMANCE MODELING of wind-turbine-gearbox bearings with field data suggests that taming torque reversals could lengthen a gearbox-bearing life up to two fold. The field data was collected by engineers at AeroTorque and supplied to bearing simulation and prediction firm Sentient Science. The later company has collected data on millions of military aircraft bearings and…

Wind turbine gearboxes are a little more reliable since researchers at The Timken Company have been able to reproduce smearing damage on bearings in the lab. Producing it means they know what causes it, and later tests on selected surface treatments show that one works well eliminating the damage. “Smearing is a damage mechanism in…

Engineers from the University of Sheffield have developed a novel technique to predict when bearings inside wind turbines will fail. A method, published in the journal Proceedings of the Royal Society and developed by Mechanical Engineering research student Wenqu Chen, uses ultrasonic waves to measure the load transmitted through a ball bearing in a wind turbine.…

Morgan Advanced Materials’ Electrical Carbon business recently announced new grounding brush holders, designed for stability and reliable dissipation of current to prolong bearing life. The grounding brush holders have a contact drop of less than one volt because to their high quality silver-graphite brush. DC motors applied on static drive systems and AC motors on adjustable-speed drives…

Research conducted by The Timken Company to address a critical issue for wind turbine operators received the 2015 Wilbur Deutsch Memorial Award from the Society of Tribologists and Lubrication Engineers (STLE). Timken researchers solved customer problems in the wind energy sector and underscored the value of Timken wear-resistant bearings in helping to prevent smearing damage to turbine…

Where are bearings used in a wind turbine? Although bearings are used many places throughout a nacelle, such as in the yaw and pitch bearings and on the generators, those on main shafts and gearboxes are most problematic. In main-shaft bearings, modular wind-turbine designs commonly use spherical-roller bearings (SRB) units that are more than 1m…

Morgan Advanced Materials’ electrical carbon business recently announced the release of its grounding brush holders, designed for stability and reliable dissipation of current to prolong bearing life. The grounding brush holders have a contact drop of less than 1 volt due to their high quality silver-graphite brush. DC motors applied on static drive systems and AC…

Bearing trends mainly focus on extending bearing life and reducing issues with wear, which is the primary cause of turbine-component failures, a problem that has long plagued the wind-energy industry. Due to this, many OEMs have accepted the challenge to developing and perfecting a high-performance bearing. The goal is to catch a bearing problem before it…

igus has recently released information on its new iglide L500 material, suitable for applications in fans and electric motors, among others. With the new material, the manufacturer has announced the release of their newest specialist bearing solution, ideally suited for continuous operation in high-speed rotation applications under low loads. The L500 material combines wear resistance in long-running,…
