Definitions
- the invention relates to grease compositions made from a base oil mixture which consists of a hydrocarbon oil and a perfluorinated polyalkyl ether oil and a small proportion of thickener based on a diurea compound and conventional additives which are used at temperatures of more than 180 ° C. to 250 ° C. have a particularly noise-reducing behavior, and a method for producing these grease compositions.
- Lubricants are used in vehicle technology, conveyor technology, mechanical engineering, office technology as well as in industrial plants and machines, but also in the areas of household machines and consumer electronics.
- the lubricants ensure that a separating, load-transmitting lubricating film is built up between parts sliding or rolling on one another. This ensures that the metallic surfaces are not touch and therefore no wear occurs.
- the lubricants must therefore meet various requirements, including:
- extreme operating conditions such as very high and very low speeds and loads, high temperatures which are caused by high speeds and loads or by external heating, very low temperatures by low self-heating of the bearings in a cold environment or by intensive heat dissipation to the cold environment , special requirements of the user regarding the running properties, eg low friction, low noise, the requirement for extremely long running times without relubrication in the meantime, unfavorable ambient conditions and inadequate sealing of the bearing point, and
- the noise characteristics of the lubricant are important parameters for the long service life of a grease-lubricated rolling bearing in the high temperature range.
- a lubricating grease can stimulate vibrations in the rolling bearing during partial rotation (rollover, walking), which are "lubricant noises" in the frequency bands 300 to 1800 Hz and High 1800 to 10000 Hz, compared to the bearing noises in the frequency band Low at 50 to 300 Hz.
- the lubricant noise is superimposed by the noise peaks which arise when hard particles are rolled over by the rolling elements in the form of shock pulses on the bearing ring.
- noise behavior is assessed according to the SKF-Bequiet method, which is based on the statistical evaluation of the noise peaks and the assignment to noise classes BQ1 to BQ4.
- the noise behavior and the service life of the rolling bearing deteriorate (H. Werries, E. Paland, FVA study on the subject of "low-noise lubricating grease", University of Hanover 1994).
- 100% noise class BQ1 characterizes very good, and low percentages only in noise class BQ4 very bad noise behavior.
- the better the noise behavior of a lubricating grease the lower the vibrations of the bearing which are forced by the lubricant. This is synonymous with a lower load on the rolling bearing and a longer service life of the bearing.
- a lubricant composition which comprises a base oil such as trimethylolpropane pelargonate, pentaerythritol pelargonate, polyphenyl ether, perfluoroalkyl ether and mixtures thereof, and a thickener such as a di- or polyurea.
- the diurea can be made from a diisocyanate and an amine such as octylamine and aniline.
- the lubricant composition can contain boron nitride or polytetrafluoroethylene (solid lubricant) and additives.
- European patent application EP-A 94 118 667.8 describes lubricating greases which are based on a mineral or a synthetic oil based on hydrocarbons, thickened with a perfluorinated polyalkyl ether with an organic or an inorganic thickener.
- the weight ratios of lubricating oil and perfluorinated polyalkyl ether / thickener are in the range from 97: 3 to 80:20 and the ratio of lubricating oil / perfluorinated polyalkyl ether is in the range from 95: 5 to 60:40.
- lubricating greases extend the operating time at a service temperature of 170 ° C to 175 ° C when the perfluorinated polyalkyl ether component is admixed.
- Low-noise lubricating greases are known from US Pat. No. 5,145,591, which are based on thermally stable polyphenyl ethers, alkylated phenyl ethers, polyol esters and aromatic carboxylic acids, which are compressed with 5 to 30% by weight of di- and / or polyureas, which are used in the above Operating temperatures of 180 ° C according to DIN 51 825 can be used.
- greases For use temperatures above 180 ° C, greases must be used which are based entirely on perfluorinated polyalkyl ethers thickened with PTFE, inorganic thickeners such as bentonites, aerosols or metal soaps or metal complex soaps , are used.
- the aim of the invention is to provide a lubricant composition which meets the above-mentioned requirements, can be used in particular under high temperature conditions and has very good noise behavior, and has long running times and essentially no wear and tear on the rolling bearing.
- a lubricating grease composition consisting of a mixture of an oil based on hydrocarbons, a perfluorinated polyalkyl ether oil and a diurea as a thickening agent and conventional additives is provided.
- the hydrocarbon-based oil is made from an ester of an aromatic di-, tri- or tetracarboxylic acid, with one or a mixture of C 7 to C 22 alcohols, a polyphenyl ether or alkylated polyphenyether, an ester of trimethylolopropane, pentaerythritol or dipentaerythritol aliphatic C 7 to C 22 carboxylic acids, C 18 dimeric acid esters with C 7 to C 22 alcohols, complex esters, prepared as individual components or in any mixture.
- the perfluorinated polyalkyl ethers of the grease compositions according to the invention have the general formula
- a '' is the same as A 'or is different -CF 3 , -C 2 F 5 , -C 3 F 7 , -CF 2 T, where TH corresponds to Cl, and v, w, x, y and z are integers ⁇ O are.
- the perfluorinated polyalkyletherols which are preferably used are thermally stable oils with low evaporation rates at 200 ° C., such as commercially available aflunox, fomblin, crytox or demnum oils which are used in the grease compositions according to the invention.
- the grease compositions that meet the requirements in the high temperature range can only be produced with perfluorinated polyalkyl ethers.
- the lubricating grease compositions according to the invention contain customary additives against corrosion, oxidation and for protection against metal influences, which act as chelate compounds, radical
- the lubricating grease compositions according to the invention are mixed in a ratio of greater than 60/40 of hydrocarbon-based oil and perfluorinated polyalkyl ether oil and thickened with 5 to 30% by weight of the diurea compound and contain up to 10% by weight of additives and / or up to 10% by weight of organic or inorganic solid lubricants.
- These solid lubricants can e.g. Polyimides, PTFE, graphite, metal oxides, boron nitride, molybdenum disulfide or phosphates.
- the viscosity of the hydrocarbon-based oil is in the range from 100 to 500 mm a / s and that of the perfluorinated polyalkyl ether oil is 10 to 1500 mm 2 / s.
- the grease compositions have dropping points according to DIN ISO 2176 of> 240 ° C and are suitable according to DIN 51825 for upper service temperatures up to 250 ° C.
- the grease compositions according to the invention are obtained either by mixing the hydrocarbon-based oil thickened with diurea with the perfluorinated polyalkyl ether oil and then homogenizing it via a high-pressure homogenizer and / or three-roller mill, or by mixing the hydrocarbon-based oil with the perfluorinated polyalkyl ether oil and is thickened in this mixture by synthesis of the diurea compound and then homogenized using a high-pressure homogenizer and / or three-roll mill.
- the invention is illustrated by the following examples.
- the fat is homogenized by a single high-pressure homogenization and subsequent rolling on a three-roll mill. In this way, a grease of NLGI class 2 according to DIN ISO 2137 is obtained. This grease obtained in this way is tested on a noise test bench. A particularly low-noise behavior was measured compared to commercially available lubricating greases.
- the grease composition was prepared analogously to Example 2, with the exception that the oil mixture presented consisted of 800 g of ester oil and 800 g of perfluorinated polyalkyl ether.
- the grease composition was prepared analogously to Example 2, with the exception that the oil mixture presented consisted of 800 g of ester oil and 500 g of perfluorinated polyalkyl ether.
- the grease composition was prepared analogously to Example 2, with the exception that the oil mixture presented consisted of 800 g of ester oil and 200 g of perfluorinated polyalkyl ether.
- the grease composition was prepared as in Example 2, with the exception that the 800 g of espresso no perfluorinated polyalkyl ether was added. In this way, a grease of NLGI class 2 according to DIN ISO 2137 with particularly low-noise behavior is obtained.
- Example 6 The grease composition of Example 6 was placed her ⁇ , with the exception that instead of 800 g Esteröl from trimellitic acid and C 8 - and C 10 alcohols Esteröl 800 g of pyromellitic acid and C 8 - and C were used 10 alcohols.
- PFPE perfluorinated polyalkyl ether
- PTFE polytetrafluoroethylene
- Table 1 shows the measurement results with regard to the noise test of the grease compositions according to DIN ISO 2137 prepared according to Examples 1 to 8.
- Table 2 shows the weight ratios of the grease compositions of Examples 1 to 8.
- Tables 1 and 2 show that the lubricating grease B6 based on an ester oil thickened with diurea exceeds the requirements for an upper operating temperature of 180 ° C according to DIN 51825 by a factor of 5, but the criterion of an L 50 running time of at least 100 hours according to DIN 51825 on the FAG FE-9 roller bearing testing machine at 200 ° C is not nearly fulfilled.
- the criterion of an upper service temperature of 200 ° C. is only met with thermally very stable diurea chains based on pyromellitic acid esters (B7).
- Table 3 shows that by adding perfluorinated polyalkyl ether oil an upper service temperature of 220 ° C according to DIN 51825 can only be reached if the mass fraction of perfluorinated polyalkyl ether in oil mixture with lubricating oil based on hydrocarbons is over 40% by weight.
