“…Through the structural design of these two types of bearings, the requirements of generators for high precision and low noise can be achieved [ 32 , 33 ]. Nevertheless, when selecting raw materials for the bearings, their insulating properties should be considered to avoid damage to the bearings caused by current pitting [ 34 ]. Pitch bearing is being used to adjust the rotation angle of the blades for the purpose of regulating the windward direction of the blades and optimizing the electrical power delivery [ 35 ].…”

Wind power, being a recyclable and renewable resource, makes for a sizable portion of the new energy generation sector. Nonetheless, the wind energy industry is experiencing early failure of important components of wind turbines, with the majority of these issues also involving wind power bearings. Bearing dependability is directly tied to the transmission efficiency and work performance of wind turbines as one of its major components. The majority of wind turbine failures are due to bearings, and the vast majority of bearing failures are due to lubrication. The topic of improving the accuracy and life of wind power bearing motion is becoming increasingly essential as the wind power industry develops rapidly. This study examines the various constructions and types of wind turbines, as well as their bearings. We also examined the most typical causes of friction and lubrication failure. Furthermore, contemporary research on wind turbine bearings has been compiled, which mostly comprises the study and development of lubrication technology and other areas. Finally, a conclusion and outlook on current challenges, as well as future research directions, are offered.

Cu nanoparticles as N32 base oil additives are studied in the paper and their structure is characterized by transmission electron microscopy (TEM) and X-ray powder diffraction spectroscopy (XRD). The widely used steel-steel friction system is chosen to test the feasibility and practicality of Cu nanoparticles as bearing lubricant additives. The results show that N32 base oil with 0.5% Cu nanoparticle can improve the test sample contact fatigue life than pure N32 base oil.

The purpose of this paper is to examine how the fatigue life of ball bearings is affected by hard turning. Two different batches of 6309 deep-groove ball bearings were manufactured. The batches had identical balls, cages, and outer rings. The inner rings were soft machined and heat treated in the same way. The inner rings were subsequently processed in two different ways; one batch was ground and honed and the other was hard turned and honed. The bearings were then assembled, and tests were conducted on test rigs designed for bearings. The purpose of the test was to determine the fatigue life of the bearings by means of the inner ring. Based on the results it can be concluded that hard turning improves the fatigue life of ball bearings.
