“…Due to relative movement and poor sealing, external pollutants entering the bearing will cause wear, poor lubrication and assembly errors will also cause wear or scratch. In addition, hard particles entering the bearing from the outside will also cause indentation or scratch [10] .…”

Gearbox is an important component of wind turbine, and its reliability is closely related to the running state of wind turbine and the economic benefits of wind farm. Firstly, this paper introduces the structure and function of gearbox. Then, taking a wind farm with gearbox failure as an example, the failure types of gearbox are analyzed by endoscopic examination and on-site dismantling. Finally, the causes of failures in actual operation are analyzed, which provides guidance for preventive maintenance and failure treatment of wind farm.

“…Historically a majority of variable speed wind turbines have used doubly fed induction generator technology with a multistage gearbox (Polinder et al, 2005). Gearboxes, however, manifest relatively high failure rates and so lost revenue due to downtimes and repairs has become a major concern of the wind energy industry (Su et al, 2017;Dabrowski and Natarajan, 2015). New systems have there-fore been developed which require gearboxes with fewer stages or are direct-drive (DD), removing the gearbox completely.…”

“…Inclusions within bearing materials are known to increase the risk of premature failures due to them acting as a nucleation site for subsurface cracks and spalling (Jalalahmadi et al, 2011;Lund, 2010;M. Evans et al, 2013); much effort has therefore been made to refine steel-making process in order to ensure a high level of bearing material homogeneity and cleanliness (Tabatabaei et al, 2018;Ni et al, 2017;Michelic et al, 2011). As a consequence, the probability of large non-metallic inclusions (> 5 µm) in small-sized bearings is low.…”

A review of wind turbine main bearings: design, operation, modelling, damage mechanisms and fault detection

et al. 2020

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. The operational conditions and loading for wind turbine main bearings deviate significantly from those of more conventional power plants and other bearings present in the wind turbine power train, i.e. those in the gearbox and generator. This work seeks to thoroughly document current main-bearing theory in order to allow for appraisal of existing design and analysis practices, while also seeking to form a solid foundation for future research in this area. The most common main-bearing setups are presented along with standards for bearing selection and rating. Typical loads generated by a wind turbine rotor, and subsequently reacted at the main bearing, are discussed. This is followed by the related tribological theories of lubrication, wear and associated failure mechanisms. Finally, existing techniques for bearing modelling, fault diagnosis and prognosis relevant to the main bearing are presented.Published by Copernicus Publications on behalf of the European Academy of Wind Energy e.V.

Abstract. This paper presents a review of existing theory and practice relating to main-bearings for wind turbines. The mainbearing performs the critical role of supporting the turbine rotor, with replacements typically requiring its complete removal. The operational conditions and loading for wind turbine main-bearings deviate significantly from those of more conventional power plants and other bearings present in the wind turbine power-train, i.e. those in the gearbox and generator. This work seeks to thoroughly document current main-bearing theory in order to allow for appraisal of existing design and analysis practices, while also seeking to form a solid foundation for future research in this area. The most common main-bearing setups are presented along with standards for bearing selection and rating. Typical loads generated by a wind turbine rotor, and subsequently reacted at the main-bearing, are discussed. This is followed by the related tribological theories of lubrication, wear and associated failure mechanisms. Finally, existing techniques for bearing modeling, fault diagnosis and prognosis relevant to the main-bearing are presented.
