Wind turbines are sophisticated machines, operating in demanding environments. This being so, it is very important to select the right lubricant, as the proper oil choice can improve wind turbine availability. This article focuses on the challenges in wind turbine lubrication, specifically addressing the use of an advanced synthetic gear oil, Mobilgear SHC XMP 320, in the main wind turbine gearbox.
ExxonMobil began tracking wind turbine gear box lubrication in 2000, and over the last 12 years has collected over 38 000 oil sample results. In framing the performance of the lubricant, it looked at system wear, oil oxidation stability, viscosity retention and water contamination, as these are the main determinants of proper gearbox operation.
