Definitions
- the present invention relates to a lubricating composition for application to the surface of drive elements such as roller bearings, gears, plain bearings and chains.
- the composition is suitable for preventing, reducing or avoiding signs of fatigue in the material of drive elements, such as micropitting, false brinelling and white etching cracks.
- Another object of the present invention is the use of the lubricant composition for treating surfaces of drive elements and the further use of such drive elements.
- One measure is to increase the thickness of the lubricating film.
- Fatigue wear is caused by local overloading of the material due to periodic compressive stress.
- the fatigue of the material becomes visible through gray spots (grey staining, surface fatigue, micro-pitting) or pits on the surface of the material.
- gray spots grey staining, surface fatigue, micro-pitting
- fine cracks appear in the metal lattice initially 20 to 40 ⁇ m below the surface, which lead to material breakouts.
- the small microscopically visible break-outs on the tooth flank known as micropitting or gray spot formation, can be recognized macroscopically as dull gray areas.
- gray spots can usually be observed on the tooth flanks in practically all speed ranges.
- very flat pitting occurs as gray spots on the raceway in the area of the sliding contact.
- White etching cracks can lead to fatigue damage that occurs much earlier than is to be expected for a drive element with given load parameters.
- False brinelling is a form of damage that occurs in bearings that appear to be stationary. Micro-movements are introduced into the contact surfaces as a result of vibrations (e.g. in machines, but also during transport by means of motor vehicles, rail vehicles or ships) or elastic deformations, which can lead to damage after just a few load changes. This can lead to unsteady running behavior and immediate or early component failure.
- Various additives are also used to improve the viscosity properties in lubricants in order to avoid or at least minimize the above-mentioned damage in roller bearings, gears, gears and the like.
- additives were investigated that can be used to reduce friction between the components or that have improved viscosity.
- the EP 1 642 957 A1 relates to the use of MoS2 and molybdenum dithiocarbamate, which are used as additives in urea greases for cardan shafts.
- the additives known from the prior art described above are not thermally stable as organic substances.
- they can evaporate under the operating conditions or, as classic anti-wear additives, can react primarily with the metal surfaces, ie they react primarily at the roughness points that are in contact, since the lightning temperatures that occur there provide sufficient energy for a chemical reaction with the metal friction layer is present. They can therefore counteract fatigue damage to a lesser extent at best.
- Solid lubricants such as Molybdenum disulfide, on the other hand, due to its density, tends to settle out of oil formulations and can also be corrosive.
- DE 102011103215 A1 describes the use of a composition containing surface-modified nanoparticles and a carrier material that is applied to the surfaces of drive elements to prevent or reduce fatigue damage. It is assumed that the mechanism of action of the nanoparticles is based on the fact that they accumulate on the surface of the drive elements and thereby smooth them out. The smoothing increases the contact surfaces and reduces the surface pressure.
- JP 2006144827 A names compositions with silica nanoparticles to suppress WEC damage.
- the subject of the present invention is a lubricating composition for application to the surface of drive elements, the lubricating composition containing a base oil and a silasesquioxane.
- the composition is suitable for preventing, reducing or avoiding signs of fatigue in the material of drive elements, such as micropitting, false brinelling and white etching cracks.
- the positive influence of the lubricant composition is surprising, since silasesquioxanes are significantly smaller than those in the publications DE 102011103215 A1 and JP2006144827A are nanoparticles and it could therefore not be assumed that, analogously to these particles, they can bring about a reduction in the signs of fatigue by smoothing the surface.
- the composition according to the invention can be mixed homogeneously with base oils of the most varied of polarities, since the polarity of the composition can be easily adjusted, for example, via the selection of the substituents of the silsesquioxane.
- the polarity of the composition can be easily adjusted, for example, via the selection of the substituents of the silsesquioxane.
- due to its production process sufficient saturation of the OH groups of the silasesquioxane can be guaranteed.
- the use of silasesquioxane enables high storage stability and that there is no impairment of foaming behavior or filterability.
- silsesquioxanes which are liquid at room temperature (20° C.) and/or have low melting points (preferably below 100° C., DIN EN ISO 11357-2 (edition: 2014-07)) can be used favorably .
- Silsesquioxanes are organosilicon compounds and form cage-like structures with Si-O-Si bonds and tetrahedral Si corners.
- the silsesquioxane can have 6 to 12 Si corners in molecular form and/or be present as an oligomer and/or polymer.
- Molecular silsesquioxanes are preferred according to the invention, more preferably molecular silsesquioxanes with 6 to 12, more preferably 7 to 10, in particular with 7 or 8 Si corners.
- each Si center is bonded to three oxo groups, which in turn connect to other Si centers.
- the Si centers are only partially bonded to three oxo groups bonded to other Si centers, and there are, preferably three, Si centers bonded to only two oxo groups bonded to other Si centers.
- the third group herein is preferably a substituent, more preferably a hydroxy substituent.
- the fourth group on the Si is also preferably a substituent, whereby a surface-modified silsesquioxane can be obtained, which is preferred according to the invention.
- suitable substituents are alkyl (C1-C20), cycloalkyl (C3-C20), alkenyl (C2-C20), cycloalkenyl (C5-C20), alkynyl (C2-C20), cycloalkynyl (C5-C20) -, aryl (C6-C18) or heteroaryl group, oxy, hydroxy, alkoxy (C4-C10), oxirane polymer (degree of polymerization with 4 to 20 repeat units)-, carboxy, silyl, alkylsilyl, alkoxysilyl , siloxy, alkylsiloxy, alkoxysiloxy, silylalkyl, alkoxysilylalkyl, alkylsilylalkyl, halogen, epoxy (C2-
- Preferred substituents are hydroxy, alkyl (C4-C10), aryl (C6-C12), especially phenyl and tolyl, alkoxyl (C4-C10), alkenyl (C2-C10), oxirane polymer, especially polyethylene glycol, polypropylene glycol, polybutylene glycol and/or or their copolymers (degree of polymerisation 4 to 20, in particular 10 to 15 repeating units), epoxy (C2-C10) and/or cycloalkyl (C5-C10), each substituted or unsubstituted.
