Definitions

  • the present invention relates to a lubricant composition for application to the surface of drive elements, such as rolling bearings, gears, plain bearings and chains.
  • the composition is suitable for fatigue in the material of driving elements, such as
  • Another object of the present invention is the use of the lubricant composition for
  • Additives and solid lubricants that are well known and widely used. To prevent fatigue damage very few effective measures are known. One measure is the increase of the lubricating film thickness.
  • Fatigue wear is caused by local overload of the material due to periodic compressive stress.
  • the fatigue of the material becomes visible through gray staining, surface fatigue, micro-pitting or pits on the surface of the material.
  • the small microscopically visible eruptions on the tooth flank referred to as micro-pittings or pitting, can be recognized macroscopically as dull gray areas.
  • gray spots on tooth flanks can generally be observed in virtually all speed ranges. Even in rolling bearings very shallow eruptions occur in the area of the sliding contact as gray patches on the track.
  • WEG White etching cracks
  • Loading parameters is expected. Metailographically, white cracks in the depth of the microstructure can be detected. The white discoloration is based on the fact that the appearing as white cracks are not subject to the etching required in the sample preparation. These cracks can lead to outbreaks in the material and failure of the component with further tribological stress. As a cause, several factors such as slippage, harmful currents and diffused hydrogen are discussed. As is known, such damage occurs in particular in warehouses of
  • False brinelling is a form of damage that occurs in seemingly stationary bearings. Vibrations (for example in machines but also during transport by motor vehicles, rail vehicles or ships) or elastic deformations micro-movements are introduced into the contact surfaces, which can lead to damage after a few load changes. This can lead to restless running behavior and to immediate or early component failure.
  • Lubricants used different additives to avoid or at least minimize the above-mentioned damage in rolling bearings, gears, gears and the like.
  • various studies have been made to avoid fatigue, including an attempt to improve the lubricity of lubricants by adding various additives.
  • additives have been investigated which can reduce the friction between the components or which have an improved viscosity.

  • Molybdenum dithiocarbamate which are used as additives in urea fats for cardan shafts.

  • Solid lubricants such as Molybdenum disulphide, on the other hand, tends to settle out of oil formulations due to their density and can also be corrosive. Since the solid particles are used with particle sizes in the micrometer range, there is a strong influence on the flow behavior and an increase in viscosity and a deviation from the Newtonian

  • Composition can be homogeneously mixed with base oils of different polarities, since, for example, the choice of the substituents of Siiasesquioxans the polarity of the composition can be easily adjusted. In addition, due to its manufacturing process, sufficient saturation of the OH groups of the Siiasesquioxans can be ensured. Furthermore, it was found that the use of

In practical experiments it has also been found that silsesquioxanes which are liquid at room temperature (20 ° C) and / or low melting points
