Abstract
The manufacturing, installation, operation and dismantling of wind turbines can also have environmental impacts such as excessive carbon emissions and consume large amounts of resources. Optimisation of the tribological properties of wind power greases can reduce the energy consumption and carbon emissions of wind power systems, improve their operational efficiency and reliability, thereby slowing down climate change and improving environmental quality, which is not only important for individual wind power projects, but also has a positive impact on reducing carbon emissions, promoting clean energy development and combating climate change on a global scale. However, the higher the grease lubrication performance, the lower the wind turbine failure rate and the lower the carbon emissions. Good tribological properties can significantly reduce the coefficient of friction of mechanical components, reducing surface wear and heat generation, helping to extend the life of mechanical equipment, improve efficiency and reduce unnecessary repairs and replacements. Therefore, in this paper, Mobil SHC 461WT lithium composite grease was mixed with molybdenum dialkyl dithiocarbamate (RFM3000), nano-boronated rare-earth friction modifiers (SK3115), polysiloxane viscosity modifier (PV611), and zinc dialkyl dithiophosphate (ZDDP), and the comparative analysis of their tribological performances was carried out through the method of cross-experimentation. The results showed that the average coefficient of friction of Mobil added with the four antiwear additives was reduced by 74 %, 41 %, 54 % and 48 %, respectively, and the average diameter of wear spots was reduced by 64 %, 63 %, 69 % and 54 %.
