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.
Does a main shaft bearing provide fatigue resistance in offshore wind turbines?
Therefore, as one of the core transmission parts of offshore wind turbines, the main shaft bearing (such as TRB) needs to ensure sufficient fatigue resistance during this period. In this section, different practical issues are considered to demonstrate the effectiveness and benefits of the proposed method.
What is the main source of wind turbine bearing current?
In this study, different wind turbine configurations for bearing current study are proposed. Based on these configurations, the wind turbine main shaft bearing current source are analyzed. The CMV and the ESD effect is confirmed to be the main source of the bearing current.
Are turbine rotor blades a source of main shaft bearing current?
Additionally, the study reveals Electrostatic Discharge via turbine rotor blades as another major source of main shaft bearing current. The often-unnoticed rotor blades' electrostatic discharge effect is further examined in a laboratory experiment.
Why do wind turbine bearings have a unique design?
Moreover, the bearing’s unique design prevents roller-to-raceway contact stress peaks from developing as a result of the periodic bending of the rotor shaft during operation or accuracy errors that arise from the initial assembly inside the wind turbine’s nacelle.
