6 FAQs about [Wind turbine bearing grease]
What are the differences between grease lubricants for wind turbine pitch bearings?
It is apparent that there are significant differences between the greases, i. e., different base oil types, base oil viscosities between 13 and 420 mm 2 /s, different thickener types, NLGI classes from 1 to 2 are compared. The lack of a red line in the grease compilation shows the complexity of grease lubricants for wind turbine pitch bearings.
Do wind turbine bearings need lubrication?
Furthermore, due to the constant rotation of the hub, the used lubricant must remain in place. Therefore, the pitch bearings in wind turbines are usually lubricated with grease. Several publications already focused on grease composition for wear reduction of oscillating rolling element bearings , , , .
What is the use of Grease in wind turbines?
The grease is highly suitable for lubricating bearings that operate under both radial and axial loads, such as on wind turbine main shafts. It is suitable for extreme pressure, low temperature applications. It offers good corrosion protection, and has good water resistance. It operates in a temperature range of -30 to 110°C.
Which lubricants are used in pitch bearing of wind turbines?
The lubricants contain additives and solid lubricants, which may influence the wear behaviour. Since the focus of the work is the comparison of industrial grease lubricants, which are used in pitch bearing of wind turbines, the chemical composition of the greases is not fully known.
Do wind turbine pitch bearings wear?
The combination of oscillating operation, high loads, and mixed lubrication often leads to wear. Grease lubricants in wind turbine pitch bearings should be designed to avoid such wear. Due to different available grease lubricants, the anti-wear properties are investigated under downscaled wind turbine pitch bearing conditions.
Are pitch bearings lubricated with grease?
Therefore, the pitch bearings in wind turbines are usually lubricated with grease. Several publications already focused on grease composition for wear reduction of oscillating rolling element bearings , , , . Due to the instationary and heterogeneous operating conditions in wind turbines these results are not directly transferable.
