Definitions
- the present invention relates to a fitting, for example a pull-out guide, in particular for a baking oven, with at least two rails which can be moved relative to one another and which are guided against one another via rolling elements
- EP 1589291 A1 discloses a generic pull-out guide which has rolling elements mounted in a rolling cage.
- the WälzSystemkorfig on a lubricating layer which u.a. the inclusion of boron nitride in a paint provides.
- the coating extends over the entire surface of the rolling element cage. Since boron nitride is used only for reasons of cost in areas in which its special material properties are absolutely necessary, when using this compound, the most cost-effective application is required. A large-area coating as in EP 1589291 A l is therefore not useful.
- the object of the present invention is to provide a fitting, in particular a pull-out guide, and a lubricant which, even when using rigens and when using high temperatures over a long period of time a smooth running of the rails allows.
- the lubricant contained in the boron nitride and / or polysiloxane is applied to the significantly smaller areas of the raceways at least in regions. This allows a targeted lubrication with less material consumption.
- Hexagonal boron nitride has proven to be an optimal lubricating and lubricating agent in the range of higher temperatures. It is chemically inert and oxidation resistant with the exception of alkaline melts and basic solutions.
- the structure of the boron nitride is similar to that of graphite and from a temperature of 900 0 C, boron nitride converts to cubic ß-boron nitride.
- the application of the lubricant is preferably carried out as a lubricating paste, suspension or in powder form. This allows the lubricant to be used for industrial series production. In addition, these application forms enable a very exact selection and coating of the application surfaces.
- the lubricant mixture is according to a preferred embodiment, a mixture of boron nitride, graphite and high-temperature grease, with a mass fraction w
- the lubricant may advantageously contain as polysiloxane preferably a Siükonpaste, a silicone grease and / or a silicone oil which does not burn at temperatures above 300 0 C, so for example in the pyrolysis of ovens.

- the consistency between these embodiments can be varied by mixing.
- Post-treatment after application of the lubricant by vibratory grinding enables better distribution and adhesion of the lubricant and lubricant on the metallic substrate.
- the lubricant has a temperature resistance of above 600 0 C, which allows, for example, an application in the range of cooking ovens and their purification by pyrolysis.
- the lubricant has a thixotropy, which decreases in these pastes under mechanical action whose viscosity and the original viscosity sets only after prolonged standing again.
- the pastes can be relatively easily distributed on the surface of the drawer guides under pressure load. This is the case with BNC pastes, for example.
- the viscosity of a lubricant without the addition of solids is advantageously in the range between 50-1500 mm 2 / s, preferably 100-1000 mmVs, whereby an application of the low to medium viscosity mass can be carried out without the lubricant flowing out at the ends of the webs can.
- the lubricant is so hydrophobic that a bacterial or fungal attack of the lubricant is excluded.
- the low surface tension in conjunction with a pronounced surface activity at 25 ° C of 20-22 mN / m, preferably from 20.9 to 21 s, 2 mN / m allows the complete wetting of a large-area substrate upon application despite a high viscosity of a lubricant.
- the carrier substance Depending on the carrier substance, it is decomposed predominantly into water and carbon dioxide during the pyrolysis.
- the boron nitride and graphite content in the lubricant mixture evenly into the
- Runways of the pullout guide distributed. After decomposition of the carrier substance during the pyrolysis, at least the boron nitride remains in the tracks of the pullout guide and enables a smooth operation of the pullout guide, thus it is still lubricated. Due to the mechanical stress before the pyrolysis of the boron nitride / graphite content is incorporated in the mixture in the tracks of the statement leadership.
- the lubricant according to the invention is particularly suitable for the lubrication of fittings in household appliances such as ovens or refrigerators, through its range of use of about - 5O 0 C to about 600 0 C. Also for other areas is the
- lubricant conceivable, especially in areas where a food suitability is required.
- pullout guides, hinges, flap fittings or other moving parts, in particular on household appliances can also be lubricated with the lubricant according to the invention.
- lubricants are preferably used which comply with the FDA 21 CFR 178.3570 (US Food and Drug Administration).
- the lubricants should be registered by the NSF (National Sanitation Foundation) in the Hl category. Reference is also made to ISO 21469.
- the lubricants used preferably also meet the hygiene requirements according to the German version DIN EN ISO 21469: 2006.

- a lubricant with boron nitride and / or graphite can be carried out in the following ways: Coating the raceways with a boron nitride lubricating varnish
- Lubricants and lubricants are, for example, boron nitride and graphite, which are relatively easily distributed by friction on a surface due to their hexagonal structure and then prevent friction.

With a consistently high mechanical load, you will get an almost constant viscosity within the specified temperature range.
- the viscosity of BNC-Si lubricant is in the range between 100-1000 mm7s, is determined at 25 ° C according to DIN 51562 and classifies the BNC-Si lubricant in the category of low to medium viscosity substances. Due to the high hydrophobicity of the lubricants form a corrosion protection, which leads neither to bleeding in the temperature range, nor to oil secretions, even over long periods of time.
