Wind Turbine Lubricants

Wind Turbine Lubricants

The loads placed on wind power plants and their components are high. Consequently, choosing the right lubricant is vital – for the initial lubrication of a component as well as for relubrication during operation. After all, it’s the lubricant that has to ensure reliable function of each machine element. In wind turbines we find both fluid (oils) and consistent lubricants (greases). Major lube points are in the:

• Main gears

• yawing gears

• Main and generator bearings

• Blade pitch gears, and

• Yaw system

The lubricants used are required to offer full performance over a long service life, good load resistance and good thermal stability. For the operators, these characteristics mean long relubrication intervals for greases and long lubricant life for oils. Some of the applications where Brugarolas SA Spain Lubricants are used in wind power stations:

Main gearbox/Azimuth Gears/Pitch Gear: Brugarolas lubricants offer high scuffing resistance at normal and elevated loads, high micro-pitting resistance, good wear protection, dynamic seal compatibility, low residue formation and higher efficiencies leading to optimized yield.

Yaw Gear systems: Lubricants from Brugarolas have very good adhesion properties, no dripping off from vertical toothing, high load-carrying capacity, suitable for a wide temperature range, suitable for centralized lubricating systems, high scuffing load capacity, Good pressure absorption, Good corrosion protection and Inhibit stick-slip.

Pitch Bearing: Brugarolas lubricants offer excellent wear protection, excellent low temperature behaviour, good seal compatibility and good corrosion protection Azimuth roller/ Plain bearing/

Generator bearing/ Yaw bearing: Usage of Brugarolas lubricants will enable lesser downtimes, more production time, reduction of repair and spare parts costs, simpler logistics due to leaner range
of products and less storage.

Slew ring drives (Yaw and pitch control): Brugarolas products offer good adhesion and do not drop from tooth flanks, even in the vertical orientation unlike other lubricants. This reduces lubricant consumption, disposal and nacelle cleaning costs. Light color prevents staining of the nacelle and tower.
