Wind turbines have seen rapid development during the last several years, and lubricants are of particular importance in this context.
Lubricants play a vital role in ensuring the components conform to the required operating times. Standard lubricants are often unable to keep up with the permanently increasing performance requirements. The article provides an overview of the specific tribological requirements the most significant components of wind turbines and the specific tasks to be fulfilled by the lubricants. It shows that the advantages for wind mill operators using high-quality specialty lubricants are considerable with regard to reliability, as well as cost-benefit aspects.
