Uptower Investigation of Main and High-Speed-Shaft Bearing Reliability

National Wind Technology Center

National Renewable Energy Laboratory

Research output: NLR › Technical Report

Abstract

This purpose of this report is to summarize the investigation of the operational conditions conducive to premature main bearing wear and gearbox bearing axial cracking failures in wind turbines. The report fully describes the series of operations conducted and measurements gathered from commissioning of the instrumented drivetrain in January 2017 through the end of the wind season in May 2018.
