All-around service –– Comprehensive consulting and technical support –– Development of plant lubrication charts –– Automatic lube point monitoring by means of Klüber Maintenance Software (KMS) ––...

Component Requirements Main gearbox –– High scuffing resistance and excellent micro-pitting resistance required –– Compatibility with paints and elastomers required –– Gear operation depends also on reliability of the rolling bearings. Requirements of rolling bearing manufacturers must therefore also be met Gear motors –– High scuffing resistance and excellent micro-pitting resistance required –– Compatibility with paints and elastomers required –– Gear operation depends also on reliability of the rolling bearings.

Lubricant Comment Benefits Klübersynth GEM 4-320 N –– Synthetic high-performance gear oil for particularly low and elevated temperatures and high loads –– Oil life approx. 3 x longer than that of mineral oil based lubricants –– High FZG scuffing resistance > 14 offers protection at normal and elevated loads –– High micro-pitting resistance, both at 90 and 60 °C, protects against premature fatigue failure –– Good wear protection prevents premature rolling bearing failure –– Dynamic seal compatibility tests with NBR and FKM document protection against oil-induced leakage –– No clogging of...

Component Requirements Main bearing –– Low speeds –– Occasional oscillating motion –– High loads –– Vibration Generator bearing –– High and low speeds –– Occasional oscillating motion –– High temperatures –– High loads –– Vibration Blade pitch bearing –– Oscillating motion –– Low temperatures –– High loads –– Vibration Yaw bearing –– Oscillating motion –– High loads –– Vibration Lubricants for bearings 6

Lubricant Comment Benefits Klüberplex BEM 41-141 The ADDED value The special grease Klüberplex BEM 41-141 fulfills and exceeds all the requirements of the bearing and wind turbine manufacturers as well as the aftermarket operators. The wide service temperature range, good pumpability and metering in centralised lubricating systems plus the good grease distribution and oil release ensure trouble-free operation of wind turbine bearing systems. The good wear protection properties, even under vibration conditions, lead to extended bearing life. –– Less downtimes, more production time ––...

Component Requirements Slew ring drives (yaw and pitch control) –– Low motion amplitude –– High load –– Vertical tooth flanks –– Tendency towards corrosion Component Requirements Slip rings –– Wear and corrosion increase transition resistance Lubricants for slew ring drives and slip rings 8

Lubricant Benefits Klüberplex AG 11-461 and 462 –– The product offers good adhesion and does not drop from the tooth flanks, even in the vertical orientation (unlike other lubricants). This reduces lubricant consumption, disposal and nacelle cleaning costs –– Light colour prevents staining of the nacelle and tower –– Good pumpability and metering in centralised lubricating systems, hence trouble-free turbine operation and availability –– Anti-corrosive effect provided during non-operation as well as in offshore applications where the nacelle is exposed to salty, humid air –– Klüberplex AG...
