Betr. Patentanmeldung Sch@@ub@nmu@@@@ Hiermit möchte ich die nachfolgend beschriebene Erfindung zum deutschen Patent anmelden.Re. Patent registration Sch @@ ub @ nmu @@@@ I would like to use the following Application for a German patent described invention.
1. Beschreibung der Erfindung Gegenstand der Erfindung ist eine Schraubenmutter. Im Prinzip ist dies Schraubenmutter ftir all(;ewindeschrauben anzuwenden.Die Mutter besteht,iGegensatz zu den normalen Muttern,aus drei Teilen,und zwar aus: 1. Außenmutter,mit innen ausgebildeten Konus; 2. Einer geteilten Innenmutter,außen konisch ausgebildet; 3. Die konischen Teile sind durch Feder und Nut,oder durch Riffelung zwecks Mitnahme der Innen - und Außen teils versehen.1. Description of the invention The invention relates to a screw nut. In principle, this is a screw nut for all (; thread screws to be used consists, in contrast to normal nuts, of three parts, namely: 1. Outer nut, with internally formed cone; 2. A split inner nut, conical on the outside; 3. The conical parts are by tongue and groove, or by corrugation for the purpose of driving the inside and outside partly provided.
2. Stand der Technik Die herkömmliche Art der Schraubenverbindúngan besteht aus Schraube und Mutter.Sie sind in vielen Formen DIN-mäßig erfaßt.Das meist angewendete Material ist Stahl.Hier ist die Korrosionsbildung durch den H20 - Gehalt ir der Atmosphäre ein ausschlaggebender Faktor.Bei den übrigen Metallen treten durch die Oxydationsbildung in dem Sinne ähnliche Mängel auf.2. Prior Art The conventional type of screw connection Consists of screw and nut. They are recorded in many forms according to DIN. Most of the time The material used is steel. Here is the formation of corrosion due to the H20 content ir the atmosphere is a decisive factor, with the other metals penetrating the formation of oxidation shows similar defects in this sense.
Durch thermische Einflüsse,besonders bei höheren Temperaturen,ist die Korrosionsbildung sehr stark.Due to thermal influences, especially at higher temperatures, is the formation of corrosion is very strong.
Es gibt dem Stand der Technik gemäß viele Rostschutzmittel,auch auf dem Heißdampfsektor.Diese Erzeugnisse sind jedoch neben der Kosten auch Arbeitszeit zur Anwendung der Mittel zu berücksichtigen,wobei dies in der Praxis einer sorgfältigen Überwachung bedarf. There are many rust inhibitors in the art, too In addition to costs, these products also include working time to apply the funds to be taken into account, being careful in practice Monitoring is required.
Zum Schutze des Schraubenmaterisis gegen Kbrrosion und Oxydation werden zum Teil die Schreuban einer Oberflächenbehandlung unterzogen;wie zum Beispiel Uerzinken,Vernickeln /oder Verchromen.Ein Schutzanstrich ist jedoch aus tschnischen Gründen vor der Montags-nicht angebracht;ebenso nach der Montage.Zum Beispiel in der größten Industrie,der Chemischen,müssen ort unter großem Kostenau?wand (in der Summe von Produktionsausfall und Lohnkosten) Schraubenverbindungen gelöst werden.To protect the screw material against corrosion and oxidation In some cases the Schreuban has been subjected to a surface treatment, such as zinc-plating, nickel-plating / or chrome plating. For technical reasons, however, a protective coating is not required before Monday attached; also after assembly. For example in the largest industry, chemical, must location at great cost (in the sum of production downtime and wage costs) Screw connections are loosened.
Bei Betriebsetörungen in der Industrie treten häufig Undichtigkeiten sn Amaturen und Flaoschverbindungen auf.Zur Behebung dieser Undichtigkeiten sind Abs teilungen von Rohrleitungen,meist ganzer Produktionsbetriebe,erforderlich. Leaks often occur when there are operational disruptions in industry sn fittings and bottle connections. To rectify these leaks are Separation of pipelines, mostly entire production plants, required.
3a Vorteile der Erfindung.3a advantages of the invention.
Durch die zweiteilige Innenmutter werden die Spielräume zwischen den Zahnflanken verringert,sodass 1. Eine Korrosionsbildung verringert wird. Due to the two-part inner nut, the clearance between Reduced the tooth flanks, so that 1. Corrosion is reduced.
2. Durch grössere Anlageflächen die Sicherung gegen lösen der Schraubverbindung gegeben ist.2. Secure against loosening of the screw connection by means of larger contact surfaces given is.
Modellversuche,wobei zwei Schraubenmuttern gleicher Grösse über 3 Jahre der normalen Witterurung ausgesetzt wurden, ergaben eindeutig,dass die Eorrosonsbildung der mçeiteiligen Mutter gegenüber der normalen Mutter ca.Model tests, where two nuts of the same size over 3 Years of exposure to normal weather conditions clearly showed that the Eorrosons were formed the mçeiteiligen mother compared to the normal mother approx.
20 :8c % lag.20: 8c%.
Das lösen beider Schraubenverbindungen wurde unter Beugen mittels eines MomententtschlUssels vorgenommem.The loosening of both screw connections was done by bending of a momentary key.
Die Anzeige zeigte bei der normalen Mutter =2,25 Kg.The display showed the normal mother = 2.25 kg.
Bei der Zweiteiligen Mutter =0 Durch messer der Schraubenverbindung M12 , Mat.ST ,8 ; Vorteile der Erfindung Metallschrauben im gesamten Anwendungsbereich sind der Umwandlung von Fe2D in Fe203 durch den H20-Gehalt der Luft; d.h. Rost oder Oxydation,ausgesetzt.Die Ablösung der Gewindeflächen ist meist nicht mit normalen Werkzeugen-möglich.For the two-part nut = 0 diameter of the screw connection M12, Mat.ST, 8 ; Advantages of the invention metal screws throughout Scope of application are the conversion of Fe2D into Fe203 through the H20 content of the Air; i.e. rust or oxidation. The thread surfaces are mostly detached not possible with normal tools.
Die zerstörte Oberfläche des Gewindematerials bildet eine gegenseitige Verbindung zwischen Schraube und Mutter.Diese Verbindung kann so kompakt sein,daß s bei dem Vsrsuch einer Trennung der Schichten,der Abriss nicht möglich ist;d.h. die radiale Ablösung der Gewindeteile ist unmöglich.The destroyed surface of the thread material forms a mutual Connection between screw and nut. This connection can be so compact that s when attempting to separate the layers, demolition is not possible; i.e. the radial separation of the threaded parts is impossible.
Der besondere Vorteil meiner Erfindung Die Patentmutter sprengt sich selbst - durch die Drehung mittels des Werkzeuges.Die Gewinde werden nicht zerstört. The special advantage of my invention The godmother blows up itself - by turning the tool, the threads are not destroyed.
DIES IST NUR DURCH DIE DIAMETRALE ABLCSUNG MÖGLICH! 5. Anwendung der Erfindung In ellen Anwendungsgebieten von Korrosions -und Oxydstionsgefährdeten Schrauben.THIS IS ONLY POSSIBLE WITH THE DIAMETRAL SCALE! 5. Application of the Invention In all areas of application for those at risk of corrosion and oxidation Screws.
