After the successful completion of tests carried out both in the laboratory and in practice, Eco Gear 320 W is now approved for the initial filling of Winergy wind power transmissions. The aim of the development work was to come up with a lubricant that would lengthen service life, improve boundary layer properties as well as provide advantages in the low-temperature range. In addition, there was a requirement for a verifiable increase of the transmission efficiency due to the new oil as well as a significant increase in the energy efficiency of the turbines as a result of this. Addinol is confident that the solution is the Advantec Formula. Thanks to this formula, Eco Gear W achieves a reduction in friction and therefore reduces the oil sump temperature. These characteristics offer considerable advantages, especially if the drivetrain is subject to strongly varying stresses. The efficiency of the transmission is increased due to the reduction in transmission power loss. Furthermore, according to Addinol, Eco Gear W has an excellent air and water separation ability. Hall B7, Booth 505 Klüber Lubrication will be presenting its range of services as well as special lubricants. “We provide consultancy services to our customers for lubricant transitions, for creating lubrication schedules as well as for lubricant and component analyses. We also provide customer-specific seminars especially for the wind energy industry,” says Peter Mages, Market Manager Wind Energy. The company’s special services include the ‘GCA’ (Grease Condition Analysis). On the basis of the analysis results, the breakdown risk for expensive components or systems can be reduced and the service life of the lubricant can be maximised. The synthetic adhesive lubricant Klübersynth AG 14-61 was specially developed for gear rim and pinion drives as well as sliding bearings, for example azimuth bearings, in wind turbines. The lubricant, which can be transported with normal central lubrication equipment down to -30°C, enables problem free operation over a large temperature range and also plays a role in increasing the service life of gear rim pinion drives due to its wear protection. A further benefit of the new lubricant is its flexibility: “Klübersynth AG 14-61 produces excellent results in both transmissions and sliding bearings, so the number of lubricant types that need to be used is reduced,” according to Mages. Hall B5, Booth 525 Sika Kleben und Dichten Industrie have a new product, SikaForce-7800, in their product range. The filler, which is available for two temperature ranges with different hardening speeds, is used to repair major damage to the rotor blade surface. Impact by insects and hailstones, deep cracks, damage caused by whirled-up dust and holes in the surface can be repaired and rectified using the filler. SikaForce-7800 Blue is suitable for use in ambient temperatures of +5 to +15 °C; SikaForce-7800 Red has optimum properties for processing at temperatures between +15 and +30 °C. The surface can be sanded a few minutes after application and therefore provides a pore-free surface for painting over.SikaForce-7800 is available in cartridges for simple handling and workability. Another new product in the Sika range is SikaDur Blade Repair Kit, available as a MixPax with 300 g content. The 2-component epoxy resin system is suitable for the repair of laminated rotor blade surfaces. Sika praises the exceptional technical properties of the product. It stands out due to its excellent weather resistance. Hall B6, Booth 242 The SikaDur Blade Repair Kit is a 2-component epoxy resin supplied in user-friendly pre-mixed containers.
