Description
Gegenstand der Erfindung ist ein Verfahren, um Gleitlager für schwere Einrichtungen, beispielsweise Walzwerke oder Lokomotiven, insbesondere Gleitlager ohne Lagermetallfutter, vor Inbetriebnahme zum Einlaufen zu bringen. Das Einlaufen erfolgt gemäß der Erfindung durch Verwendung einer an sich bekannten Druckschmierung mit Öldrücken bis zu mehreren 100 at.The subject of the invention is a method to produce plain bearings for heavy equipment, for example rolling mills or locomotives, in particular plain bearings without bearing metal lining, to be run in before commissioning. The running-in is carried out according to the invention by using a per se known pressure lubrication with oil pressures up to several 100 at.
jo Bisher hat das Einlaufen solcher Gleitlager große Schwierigkeiten gemacht, weil sich die Unebenheiten der Welle und der Lagerschale bekanntlich nur sehr schwer ausgleichen und infolgedessen beim Einlaufen häufig so hohe Temperaturen entstehen, daß der Betrieb nicht weitergeführt werden kann. Man war gezwungen, entweder die Lagerschale mit großer Sorgfalt und Mühe durch Tuschieren auf die Welle aufzupassen oder das Einlaufen des Gleitlagers unter erheblichem Zeitaufwand unter geringer Belastung vorzunehmen.jo So far, the running-in of such plain bearings has caused great difficulties because the As is well known, it is very difficult to compensate for unevenness in the shaft and the bearing shell As a result, temperatures often so high during run-in that the operation cannot be continued. One was forced to either use the bearing shell great care and effort to watch the shaft by spotting or running in of the plain bearing with considerable expenditure of time under low load.
Diese Nachteile werden durch das Verfahren nach der Erfindung behoben. Durch die hohen Öldrücke werden Welle und Lagerschale vor Inbetriebnahme voneinander abgehoben mit der Wirkung, daß das Schmiermittel zwischen die Teile eindringt, die sich aufeinander einlaufen sollen. Der auf diese Weise gebildete Ölfilm zwischen Welle und Lager vermindert eine übermäßige Reibung beim Einlaufen und ermöglicht ohne Belastungsverminderung in kurzer Zeit die Ausbildung glatter Laufflächen ohne schädliche Temperaturerhöhung.These disadvantages are eliminated by the method according to the invention. Through the high oil pressures, the shaft and bearing shell are lifted from one another before being put into operation with the effect that the lubricant penetrates between the parts that are supposed to run into each other. The one on this A well-formed oil film between the shaft and the bearing reduces excessive friction when running in and enables the formation of smooth running surfaces without damaging in a short time without reducing the load Temperature increase.
Insbesondere bei Fahrzeugen, z. B. Lokomotiven, gibt die Erfindung die Möglichkeit, das Fahrzeug, das mit neuen oder frisch ausgegossenen Lagern versehen ist, im, stationären Zustand in kürzester Zeit voll betriebsfähig zu machen. Bisher mußten die Fahrzeuge leer auf größeren Strecken Probefahrten machen. Die Probefahrten fallen bei dem den Gegenstand der Erfindung bildenden Verfahren des Lagereinlaufes weg, und es wird erreicht, daß neue oder frisch ausgegossene und aufgepaßte Lager auch bei stationär bleibenden Fahrzeugen schnell unter normalen Betriebsbedingungen voll arbeitsfähig gemacht werden.Especially in vehicles such. B. Locomotives, the invention allows the vehicle, which is provided with new or freshly poured bearings, in the stationary To make the condition fully operational in the shortest possible time. So far the vehicles had to Take test drives empty on longer stretches. The test drives fall in the case of the subject of the invention Process of the bearing inlet away, and it is achieved that new or freshly poured and fitted bearings quickly full under normal operating conditions, even with vehicles that remain stationary be made able to work.
Die Erfindung ist auch bei Gleitlagern mit Lagermetallfutter anwendbar, insbesondere wenn es sich um ein hartes Eingußmetall handelt.The invention is also applicable to plain bearings with bearing metal lining, in particular if it is a hard sprue metal.
