6 FAQs about [Wind turbine generator bearing adhesion]
What is a main bearing for a wind turbine?
the Creative Commons Attribution 4.0 License. This paper presents a review of existing theory and practice relating to main bearings for wind turbines. The main bearing performs the critical role of supporting the turbine rotor, with replacements typically requiring its complete removal.
How do journal bearings deteriorate in wind turbines?
Due to dynamic and slow-speed operating conditions, journal bearings in wind turbines are generally subject to sliding wear. According to Czichos [ 1 ], the four wear mechanisms for journal bearings are adhesion, abrasion, micro fatigue and tribochemical reaction.
What are the wear modes of wind turbine bearings?
Based on FTA, the authors revealed that the abrasive wear, adhesive wear, corrosive wear, erosive wear, fretting wear, false brinelling, micropitting and surface fatigue are the most prominent wear modes exist in wind turbine bearings. And the propagation of wear and structural vibrations highly affect the bearing life. 4.
Do wind turbine generators have bearing current?
Liu et al. examined a comparative study of bearing current on three different types of wind turbine generators: doubly-fed induction generator (DFIG), direct-drive permanent magnet synchronous generator (PMSG) and semi-direct-drive PMSG by using the simulation tool.
Can planetary gear bearings be used in wind turbines?
However, there is currently no standardized approach for the wear prediction of planetary gear bearings. In addition, experience regarding the use of journal bearings in wind turbines over the 30-year operational life of a wind turbine has been limited so far.
Why do wind turbine gearboxes fail?
Around two-thirds of wind turbine gearboxes fail due to the failure of bearings . Wind turbine gearbox bearings mostly fail at three locations: highs speed bearings (carries lower loads), planet bearings (carries higher loads), and intermediate shaft bearings.
