At this year’s Hannover Messe, NKE Austria GmbH will present bearings for wind turbine gearboxes and generators. The Austrian bearing manufacturer has more than 20 years of experience in the wind energy sector. NKE bearings have been installed in more than 4,000 wind turbines across Europe, the USA and China, equivalent to more than 10,000 MW of installed power. 

PT products such as gears, motors, pumps, fans and bearings will—without a doubt—continue to run through rigorous and harsh environments for the foreseeable future, but software and hardware improvements aim to disrupt unplanned downtime and machine maintenance through a series of new condition monitoring assets.

Wind-turbine drivetrains undergo severe transient loading during start-ups, shut-downs, emergency stops, and during grid connections. Load cases that result in torque reversals may be particularly damaging to bearings, as rollers may be skidding during the sudden relocation of the loaded zone. Seals and lubrication systems must work reliably over a wide temperature variation to prevent the ingress of dirt and moisture and perform effectively at all rotational speeds in the gearbox. Many wind-turbine gearboxes have also suffered from fundamental design issues such as ineffective interference fits that result in unintended motion and wear, ineffectiveness of internal lubrication paths and problems with sealing. Improving the resistance of future gearbox designs to all these issues is a key to the future cost of energy generated by wind turbines.

The European Union aims to expand the capacity for wind power generated at sea to at least 60 gigawatts by 2030. With its sealing solutions for the foundation structures, Freudenberg Sealing Technologies helps ensure that new wind turbines reach a service life of at least 30 years or more despite the rough conditions at sea. 

The automotive and industrial supplier Schaeffler has signed a contract with the CERATIZIT Group for the acquisition of CERASPIN. Based in Livange, Luxembourg, CERASPIN has over 25 years’ experience in the development and production of premium ceramic products, the majority of which are processed into rolling elements for various bearing applications.

Danfoss Power Solutions has appointed Ines E. Sira as the new president of its Fluid Conveyance division, effective immediately. Based at the company’s campus in Eden Prairie, Minnesota, Sira will be a key member of the Power Solutions leadership team and will report directly to Eric Alström, president of Danfoss Power Solutions.

In its largest order to date, Danish wind turbine test specialist R&D Test Systems will develop the 30 MW powertrain and gearbox test bench for ZF Wind Power’s future “Test & Prototype Center” at Lommel, Belgium. Capable of simulating the multiplicity of wind loads that a nacelle powertrain might experience in its lifetime, the test rig, to be delivered in 2024, will help improve product reliability and shorten time to market.

Bonfiglioli presents the new high performant 800 series which comes in five sizes from 25,000 to 160,000 Nm in marine-resistant paint, suitable for blast cleaning. Easy and fast assembly of the 800 series gearboxes into the winch drum is a key feature of their design. Maintenance requirements are made as simple as possible, e.g., with an easy access to the brake, ready-made brake replacement kits as well as easy access to oil filling, draining plugs, and oil level pipe/indicator. 

Wind farms are expanding around the world. This is good for climate change. Wind turbines are being installed on the high seas with nacelle heights of more than 100 meters and rotor diameters of nearly 170 meters. This increases both the electricity yield and economic efficiency. Freudenberg is aiding wind power’s conquest with high performance components and materials.

We’ve covered SKF in medical, wind turbine, hand tool, solar panel, and compressor applications. We’ve examined SKF bearings utilized in crazy, out-of-this-world, aerospace applications. Nothing, however, tops the seal of approval coming from a professional skater in Europe.
