Wear Analysis of Wind Turbine Bearings
Abstract
Bearings are among the key mechanical components for conversion from wind to electrical energy in wind turbines, but their reliability are affected by the external and internal environment. Wear is among the most frequent cause of failure of wind turbine tribological components such as bearings. In this paper, a fault tree analysis (FTA) is conducted for bearing failures due to wear. Influence of material bearing and its place of installation have been investigated. Occurrence of different wear types and failure detection in bearings are studied.
