Description
Gleitlager :aus Sintereisen werden nach dem Pressen und Sintern mit 01 getränkt. je größer der Porenraum des Lagerkörpers und damit seine Ölaufnahmefähigkeit ist, um so bessere Laufeigenschaften besitzt das Lager. Den Porenraum des Lagerkörpers könnte man an sich durch Pressen des Lagers bei geringerem Druck vergrößern, hierdurch würde das' Lager aber zu weich werden, so daß es die übliche Flächenpressung nicht mehr aufnehmen könnte.Plain bearings: made of sintered iron are impregnated with 01 after pressing and sintering. the larger the pore space of the bearing body and thus its oil absorption capacity, the better the running properties of the bearing. The pore space of the bearing body could be enlarged by pressing the bearing at a lower pressure, but this would make the bearing too soft so that it could no longer absorb the usual surface pressure.
Die vorliegende Erfindung bietet die Möglichkeit, die Laufeigenschaften eines Gleitlagers aus Sintereisen erheblich zu verbessern, ohne seine Tragfähigkeit oder seine anderen mechanischen Eigenschaften zu beeinträchtigen. Erfindungsgemäß werden in dem Lagerkörper Hohlräume angeordnet, in die locker eingefülltes Eisenpulver eingesintert wird. Dies so gebildeten schwammartigen Einlagen nehmen infolge ihres großen Porenraumes beträchtliche Ölmengen auf und geben diese im Betriebe an den Lagerkörper und an die Gleitfläche ab. Als besonders zweckmäßig hat sich die Anordnung einer Ringnut an den beiden Stirnseiten des Lagerkörpers entsprechend der Abbildung erwiesen. Die Nut kann nach der Herstellung des Lagers eingedreht oder gleich mit eingepreßt werden. Im letzten Falle kann die' Füllung aus lockerem Eisenpulver bei der Sinterung des Lagerkörpers selbst mit eingesintert werden, wodurch sich eine zweite Sinterbehandlung erübrigt.The present invention provides the ability to improve the runnability of a plain bearing made of sintered iron can be significantly improved without its load-bearing capacity or affect its other mechanical properties. According to the invention cavities are arranged in the bearing body, into which loosely filled iron powder is sintered in. This so formed sponge-like deposits take as a result of their large pore space on considerable amounts of oil and give them in the company to the Bearing body and on the sliding surface. The arrangement has proven to be particularly useful an annular groove on the two end faces of the bearing body as shown in the figure proven. The groove can be screwed in after the production of the bearing or at the same time be pressed in. In the latter case, the 'loose iron powder filling can be added the sintering of the bearing body itself are sintered in, creating a second sintering treatment unnecessary.
Das abgebildete Lager nahm bei der Erprobung die doppelte Ölmenge auf wie (las gleiche Lager ohne entsprechende Füllräume.The bearing shown took twice the amount of oil during testing on how (read the same warehouse without corresponding filling spaces.
Gegenfiber anderen, noch nicht zum Stand der Technik gehörenden Bauarten kann das Lager gemäß der Erfindung dem Verbraucher fertig getränkt geliefert und in jeder Lage befördert und eingebaut werden, ohne das ÖL aus den Füllräumen zu verlieren.Compared to other types that do not yet belong to the state of the art the bearing according to the invention can be supplied and ready-soaked to the consumer can be transported and installed in any position without taking the OIL from the filling rooms lose.
Gleitlager der beschriebenen Art eignen sich besonders gut als Austauschlager an den Stellen, an denen bisher. Wälzlager benutzt «-orden sind.Plain bearings of the type described are particularly suitable as replacement bearings in the places where so far. Rolling bearings used "-order.
