Description

Verfahren zur Herstellung von Lagerbuchsen aus Blechen aus Leichtmetallegierungen Bei der weitgehenden Anwendung, welche geschlossene Lagerbuchsen im gesamten Maschinenbau gefunden haben, besteht ein Bedürfnis danach, auch die als Austauschwerkstoff wichtigen Leichtmetallagerlegierüngen in dieser Form anwenden zu können. Dem sind jedoch bisher gewisse Schwierigkeiten entgegengestanden. Um gute Lagereigenschaften zu erreichen, ist bei diesen Legierungen eine sehr weitgehende Durchknetung notwendig, wie sie in einfacher Weise nur bei der Blechherstellung zu erreichen ist. Aus Blechen geschlossene Buchsen herzustellen, ist nun möglich, aber nur auf dem Wege des Tiefziehens; dies bedingt großen Abfall und teure Produktion.Process for the production of bearing bushes from sheet metal made of light metal alloys In the widespread use of closed bearing bushes in the entire mechanical engineering sector have found, there is a need for them, including those that are important as replacement materials To be able to use light metal bearing alloys in this form. However, so far faced certain difficulties. To achieve good storage properties, a very extensive kneading is necessary with these alloys, like them can only be achieved in a simple manner in sheet metal production. Closed from sheet metal Producing bushes is now possible, but only by means of deep drawing; this causes large waste and expensive production.

Es hat sich nun gezeigt, daß es in viel einfacherer Weise möglich ist, Buchsen herzustellen, die, obwohl nicht geschlossen, den geschlossenen Lagerbuchsen gleichwertig sind. Wenn man nämlich Bänder aus Lagermetall, allenfalls in mehreren Verformungsstufen, mittels Ziehens durch eine Düse zu einem Schlitzrohr umformt, ergeben sich rohrförmige Werkstücke von hoher Maßgenauigkeit; daß diese Stücke längs einer Erzeugenden offen sind und daher immer etwas auffedern, kann beim Einbau sogar als Vorzug empfunden werden, da sie sich um so besser in die Bohrung des Lagerkörpers einzuschmi,gen vermögen. Auch besteht die Möglichkeit, durch seitliches Einschlagen eines Streifens, der einen schwachen Anzug aufweist, die Buchse gegen den Lagerkörper zu verspannen.It has now been shown that it can be done in a much simpler way is to produce bushings that, although not closed, correspond to the closed bearing bushes are equivalent. If you have bands made of bearing metal, at best in several Deformation stages, formed into a slotted tube by drawing through a nozzle, tubular workpieces with high dimensional accuracy result; that these pieces lengthways open to a generator are and therefore always spring something up, can can even be perceived as an advantage during installation, since they are all the better in the bore of the bearing body. There is also the option to go through the side Tucking a strip that has a weak suit against the socket to clamp the bearing body.

Besonders zweckmäßig erweist es sich, statt des in ganzer Dicke aus Lagerlegierung bestehenden Bleches Verbundblech zu verwenden, welches in der Hauptsache aus einer Legierung mit guten Fest!,- oder Ausdehnungseigenschaften besteht und nur einseitig eine dünne Schicht der Lagerlegierung trägt.It proves to be particularly useful instead of the full thickness Bearing alloy existing sheet to use composite sheet, which in the main consists of an alloy with good strength or expansion properties and only carries a thin layer of the bearing alloy on one side.

Es ist zwar bei der Formgebung von Rohren aus Blechstreifen ganz allgemein bekannt, die Blechstreifen durch geeignete Düsen zu ziehen. Ferner ist es bekannt, Gußblöcke aus unreinem oder legiertem Werkstoff zur Erhöhung seiner Korrosionsbeständigkeit mit Reinaluminium zu umgießen und dann durch Walzen oder Ziehen weiterzuverarbeiten.It is quite general in the shaping of pipes from sheet metal strips known to pull the metal strips through suitable nozzles. It is also known Cast blocks made of impure or alloyed material to increase its corrosion resistance to be cast around with pure aluminum and then further processed by rolling or drawing.

ach einem ferner noch bekannten, auf die Auskleidung von Lagern und nicht auf die Herstellung von Lagerbuchsen sich beziehenden Verfahren werden aus einer Lagermetalllegierung bestehende Blechzuschnitte von jeweils benötigter Abmessung eingerollt und in das auszukleidende Lager eingepaßt, und nicht, wie dies erfindungsgemäß erfolgen soll. Bänder aus Leichtmetall durch eine Düse gezogen, wodurch rohrförmige Werkstücke von hoher 'Maßgenauigkeit entstehen. Hinzu kommt noch, daß bei der Verwendung plattierter Bleche gemäß der Erfindung eine Trennung von Lager- und Grundmetall auch unter höchsten Beanspruchungen ausgeschlossen ist, während bei der bekannten Lagerauskleidung das Lagermetall nur durch seine Rückfederung gegen den Lagerkörper gepreßt wird. Eine größere Kräfte aufnehmende Verbindung besteht daher in diesem Falle nicht, wodurch auch ein größerer Verschleiß infolge des wenn auch nur geringen Arbeitens zwischen Lager und Auskleidung gegeben ist.Oh, and another still known, on the lining of bearings and Processes not related to the manufacture of bearing bushes are made a bearing metal alloy existing sheet metal blanks of the required dimensions rolled up and fitted into the bearing to be lined, and not as in accordance with the invention should take place. Strips of light metal drawn through a nozzle, creating tubular Workpieces of high 'dimensional accuracy are created. On top of that, when using it clad sheets according to the invention a separation of bearing and base metal is excluded even under the highest stresses, while with the known Bearing lining the bearing metal only through its spring back against the bearing body is pressed. There is therefore a greater force-absorbing connection in this Do not fall, which also means greater wear and tear as a result of the, even if only slight, There is work between the bearing and the lining.

Schließlich ist noch ein Verfahren bekanntgeworden, nach dem da: Lagermetall zwar zu einem Rohr gebogen wird. dieses Rohr wird aber in ein nahtloses Rohr eingeführt und durch einen weiteren Walz- oder Ziehvorgang fest mit diesem verbunden, so daß auch die Kanten des zum Rohr gebogenen Bleches fest aufeinander kommen und in ihrer Lage fixiert werden.Finally, another process has become known according to which there: bearing metal although it is bent into a tube. however, this tube is inserted into a seamless tube and firmly connected to this by a further rolling or drawing process, so that the edges of the sheet metal bent to form a pipe come tightly together and in their Be fixed in position.
