ONYX Insight has unveiled a new upgrade to its fleetMONITOR technology which will enable wind operators to monitor the health of their turbines using data from Bently Nevada System.
This report derives the equation for relative elastohydrodynamic lubrication (EHL) film thickness. Mineral (MIN), polyalphaolefin (PAO), and polyalkylene glycol (PAG) lubricants with viscosity grades of ISO 320, 150, and 32 are analyzed.
There is growing financial risk to maintaining operational wind turbines. The average lifespan of a wind turbine is around 20 years and as components within turbines begin to approach the end of their lifecycle, performance can decline resulting in reduced productivity. Meanwhile, recent reports have highlighted that new, larger capacity machines could lead to a rise in component failures and mechanical breakdown issues as manufacturers push to develop bigger turbines, faster.
NKE Austria GmbH (Booth #3C16) will exhibit at this year's Husum Wind trade show taking place September 12-15 in Husum, Germany. The Austrian bearing manufacturer participates for the first time at the fair for renewable energies in Northern Germany.
Nearthlab, a leading provider of autonomous drone technology, announced that the company is scaling up its strategic partnership with ONYX Insight, a global provider of predictive maintenance solutions (PdM) beyond North America to Europe and APAC. The expansion comes a few months after the initial kick-off in March.
Heidenhain Corporation will be exhibiting at Cleanpower, May 22-25 in New Orleans, LA. The booth (#1514) will feature technologies from two companies in the Heidenhain family of brands—Leine Linde and LTN—that can reduce challenges related to wind turbine service and boost overall uptime.
Bearing manufacturer NKE Austria GmbH is entering into a strategic partnership with Kugler Bimetal SA, a Swiss producer of bimetallic components and tribological surface finishes. The cooperation was announced at the Hannover Messe in April 2023.
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.
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.
