Lifetime lubrication of Wind Turbine Main Gearboxes

Motivation

The average lifetime of a Wind Turbine and its components is 20 to 25 years. Yet for the lubrication used in the main gearbox, a much shorter use of 3-5 years is granted. This is mainly because of conservative estimation by oil suppliers. For that reason an oil change for the main gearbox is needed regularly. In a Wind Turbine environment this is a difficult and expensive job, and large amounts of old oil have to be disposed and refilled. This research project aims to reduce the necessary oil changes and tries to figure out a possible way of runnig a wind turbine without oil change.

 

Research Goals:

  • Understanding the mechanisms for aging oil in wind turbine gearboxes
  • Identification of limits for the functionality of gearbox oil
  • Development of replenishment method to prolong the use of oil
  • Development of a prognosis tool to estimate the deterioration of the oil
