As the power rating of wind turbines is increasing, loads and temperatures acting within the confined space of the main gearbox are on the rise. Consequently, it is challenging for the gear oils used to attain service life, load and thermal resistance targets. Further critical issues are resistance to wear and micropitting as well as foam and residue formation. The Klübersynth GEM 4 N series of highly load-resistant, synthetic gear oils made by Klüber Lubrication have proven successful in improving the reliability of wind power plants around the world.
"Compared to standard oils, these high-performance gear oils from Klüber Lubrication offer high resistance to ageing and loads as well as low friction coefficients," explains Thomas Jørgensen from Business Unit Wind Energy of Klüber Lubrication. "This enables long oil change and service intervals, and higher plant yield - up to several thousand euros can be saved over the service life of a wind turbine."
The Klübersynth GEM 4 N series of gear oils offer high resistance to scuffing and micropitting as well as very good wear protection for teeth and rolling bearings. Thanks to the excellent ageing properties and oxidation resistance of these synthetic oils, they attain a much longer service life than mineral oil-based lubricants. They also show a good viscosity-temperature behaviour, supporting the formation of a sufficient lubricant film even at high temperatures. These oils possess excellent anti-foaming characteristics by the use of high quality raw materials in combination with suitable anti-foaming additives. The wide service temperature range of the Klübersynth GEM 4 N series makes it more versatile allowing customers to use a single viscosity class for both high and low temperatures.
