Description

Zur Verminderung der Reibung aufeinander= gleitender Eisen- oder Stahlteile ist es .bekannt, die Oberfläche dieser Teile zu phosphatieren. Es bildet sich dabei eine durch Verzahnung mit der Oberfläche fest auf dieser haftende Kristallhaut mit guter Ölaüfsaugfähigkeit. Insbesondere hat man die Phosphatierung von Maschinenteilen zur Behebung der Einlaufschwierigkeiten und zur Verbesserung der Laufeigenschaften von hart auf hart laufenden Teilen verwendet.To reduce the friction on one another = sliding iron or steel parts it is known to phosphate the surface of these parts. It forms in the process a crystal skin firmly adhering to the surface through interlocking good oil absorbency. In particular, one has the phosphating of machine parts to eliminate run-in difficulties and to improve the running properties used by hard on hard running parts.

Erfindungsgemäß werden phosphaterte Laufzapfen bei Lagerbüchsen aus Bleibronze, Silber; Kadmium, Zinn, Blei (Weißmetall) oder diesen Metallen entsprechenden weichen Aluminiumlegierungen verwendet, die wesentlich weicher sind als ' z. B. Stahl oder Phosphorbronze. Beim Lauf der phosphatierten Zapfen in Lagern aus den vorstehend genannten Metallen wird zwar die Phosphatschicht genau so wie bei Stahllagerschalen mit der Zeit abgetragen. Indes erfolgt diese Abtragung in verhältnismäßig längerer Zeit, so daß die günstigen Laufeigenschaften bei Weißmetallagerschalen auch länger als bei Stahllagerschalen wirl@sain bleiben. Außerdem werden die außerordentlich harten abgetragenen Teilchen wenigstens zum Teil wieder in die weicheren Lagerschalen eingedrückt, so daß man nicht von einem Schwund des Phosphatüberzuges schlechthin sprechen kann, sondern von seiner zum mindesten teilweisen Verlagerung von. dem Lauf- -zapfen auf die Lagerschalen. Erfinungsgemäß werden. also die Betriebseigenschaften derartiger Lager erheblich verbessert.According to the invention, phosphated journals are made from bearing bushes Lead bronze, silver; Cadmium, tin, lead (white metal) or equivalent to these metals soft aluminum alloys are used, which are much softer than 'z. B. Steel or phosphor bronze. When running the phosphated cones in bearings from the The above-mentioned metals, the phosphate layer is exactly the same as with steel bearing shells worn away over time. However, this removal takes a relatively longer time Time, so that the favorable running properties of white metal bearing shells also last longer stay wirl @ sain than with steel bearing shells. Besides, they'll be extraordinary hard removed particles at least partially back into the softer bearing shells pressed in, so that there is no shrinkage of the phosphate coating can speak, but of its at least partial shift from. to the Trunnions on the bearing shells. Become according to the invention. so the operating characteristics such camp significantly improved.

Infolge der durch die Verwendung phosphatierter Zapfen bei Weißmetallagern erzielten günstigen Verhältnisse ist die Verwendung von Lagern aus einem der vorstehenden Metalle an Stelle von Stahl in einem viel größeren Umfange ermöglicht, als es bisher der Fall war.As a result of the use of phosphated pins in white metal bearings The favorable ratios achieved is the use of bearings from one of the preceding Metals instead of steel are made possible to a much greater extent than before was the case.

Die Zeichnung stellt ein Ausführungsbeispiel des _ Erfindungsgegenstandes dar. r bedeutet die Kurbelwelle einer Brennkraftmaschine, a ein Endlager im Kurbelgehäuse 3 mit einer Lagerschale q, aus einem der vorstehenden Metalle. Die B;onderschicht 5 des Laufzapfens 6 ist der Deutlichkeit halber übertrieben stark gezeichnet.The drawing represents an exemplary embodiment of the subject matter of the invention r means the crankshaft of an internal combustion engine, a an end bearing in the crankcase 3 with a bearing shell q, made of one of the preceding metals. The bonding layer 5 of the journal 6 is drawn exaggerated for the sake of clarity.
