Yaw Control

For a higher and efficient energy output, the nacelle must be adjusted to the wind power as soon as the wind turbine sensor measures a change in wind direction or speed. This sets a drive mechanism in operation adjusting the nacelle slowly and precisely to the right wind direction. High loads and dynamic forces impact nacelle rotary joints and result in the long run in, high wear and premature failure. LUBCON lubricants are easy to apply, absorb vibrations, dissipate wind forces and offer efficient tribo-corrosion protection at longer operation stops for a precise and failure-free adjustment. The lubricants remain at the friction points due to the good adhesion properties and protect them permanently against wear and potential fretting corrosion.

Yaw bearing

Turmogrease SLF 4001

Vibration absorbing, well adherent lithium/calcium special soap grease with semi-synthetic base oil and a customised additive package. The particularly load absorbing special grease for pitch and yaw bearing lubrication in wind turbines withstands varying temperatures and climate conditions, protects against wear even at extreme high loads and oscillating movements and prevents false brinelling (fretting corrosion).

Turmogrease Li 802 EP

Long-life grease with lithium soap thickener for best lubricity in wind turbine generators, yaw and main bearings. The high performance grease with special additives reliably withstands, due to its constant lubricity, high speeds, vibrations, temperatures and shock loads. It enables long service life and therefore reduces repair and replacement costs. It is extremely load and age-resistant and offers good corrosion protection. The grease is perfectly suitable for lubrication with central lubrication systems.

Pitch/Yaw gear

Grizzlygrease No. 1

Outstandingly water, media and temperature-resistant, mineral oil based, lithium/calcium complex soap grease with extreme high load carrying capacity, particularly at low speeds and oscillating movements. The mechanically and chemically resistant grease for open gear lubrication absorbs vibrations, shock loads and features high wear and tribo-corrosion protection. It is very adhesive and adheres to metal surfaces even at high centrifugal forces.

Yaw drive

Turmogearfluid WKA

Especially developed long-life lubricant for the gear motor lubrication in wind turbines. The oxidation-resistant oil features good wetting properties, keeps its dynamic viscosity even at high shear loads and protects against wear, corrosion and deposit formations.

To disencumber maintenance staff and to extend maintenance intervals LUBCON offers the central lubrication system EasyMatic HD, a robust and reliable solution for the automatic yaw drive lubrication. The lubrication system supplies continuously yaw bearing and yaw gear with the right and fresh lubricant amount.
