WHY SYNTHETIC OIL?
FEATURE SPONSOR WHY SYNTHETIC OILS?
As an operator in the wind industry, you will be aware of how oil related failures in wind turbines can impact productivity, and how much any downtime can cost, which is why for trouble-free, smooth operation of wind turbines, even under extreme conditions, the right lubricant solution must be selected.
“As the importance of wind power increases, so too will the challenges to be met by wind power plants in terms of efficiency, downtime, shorter maintenance intervals, complex supplier management, and storage costs. These are just some of the challenges influencing an operators’ success, but with high-quality, tailor-made products and a comprehensive portfolio of services for the wind industry, Klüber Lubrication helps operators to overcome these challenges.” Stated Thomas Jørgensen, Sales Development Manager, Business Unit Wind Energy, Klüber Lubrication.
SUPERIOR PERFORMANCE
Synthetic lubricants offer a superior performance compared to those of conventional mineral oils, which is why high-performance products from Klüber Lubrication are selected by world renowned component and installation manufacturers for initial fill and used in numerous wind power plants worldwide, with many others being prepared for lubricant changeover.
WHY USE HIGH-PERFORMANCE GEAR OILS?
In wind turbines the risk of scuffing or micro-pitting damage which can change the shape of the tooth flank and may affect the mesh dynamics and the noise characteristics of the gears is particularly high. This is due to shock loads, vibration, high surface pressures and high sliding friction, all prevalent in wind turbines. Highly loaded gears are more susceptible, and the cracks associated with micro- pitting may even propagate, resulting in actual gear pitting and consequently premature gear failure.
In an effort to overcome the weaknesses of existing products on the market and accommodate the high loads experienced in wind turbine gears, Klüber Lubrication developed Klübersynth GEM 4-320 N. With its advanced additives, Klübersynth GEM 4-320 N has a high micro-pitting resistance of load stage ≥ LS 10 (GFT ”high“) according to the FVA 54/7 test, not only at 90°C, but also at 60°C, which is the usual inlet temperature in wind turbine gears. The gear oil offers a good resistance to load and ageing, as well as low friction, which enables longer oil change intervals, lower power losses and provides higher plant yield - by up to several thousand pounds over the service life of a wind turbine.
WHAT’S GOOD FOR GEARS NEEDS TO BE GOOD FOR ROLLING BEARINGS
Gear damage is frequently associated with rolling bearing damage, which is why the company manufacture products that are suitable for gears and the bearings in the gearbox. In the FE8 rolling bearing test developed by bearing manufacturer FAG wear should be less that 30mg, Klübersynth GEM 4-320 N delivers extremely good results with a wear rate of <10mg, far below the permissible maximum, thereby delivering huge cost savings to manufacturers and operators of wind turbines.
OPTIMALLY EQUIPPED, WHATEVER THE APPLICATION
Klüberplex BEM 34-131 N, a new speciality grease for rolling bearings offering excellent corrosion protection in very high, or very low operating temperatures where gears are exposed – as high as 120°C and as low as -30°C. The excellent wear protection even when subjected to vibration or oscillating movements extends the service life of the bearings and therefore the reliability of the wind turbine.
Klubersynth GE 46-1200, this synthetic
gear grease can be used for a variety of applications and was developed to lubricate spur gears, bevel gears and worm gears in particular. The grease can also be used to lubricate toothed couplings, ball and roller guides, and rolling and sliding bearings. The product has the benefits of polyglycol base oil in a fluid grease form, offering a high resistance to oxidation for a longer life with a low coefficient of friction.
Klübersynth AG 14-61, is an adhesive lubricant for gear rim and pinion drives, and delivers excellent wear protection and good load-carrying, contributing to the extended lifetime of the gear rim and pinion drives. Developed specifically for use at low temperatures to ensure wind energy supply during challenging winter months. Thie product remains suitably soft even at temperatures as
