Abstract

Tin and lead based alloys are widely used as journal bearing materials in tribological applications. If Al or Zn with their sliding property will be added to such materials the tribological properties of journal bearings can be improved once more. In this study, wear properties of these journal bearings manufactured from SnPbAlZn, pure Sn, pure Pb, pure Al, and pure Zn bearings were investigated. Experiments were carried out in every 30 min for the total of 150 min by using radial journal bearing wear test rig. As a result wear properties can be improved by variation of SnPbAlZn material.

Kurzfassung

Zinn- und Blei-basierte Legierungen werden vielfältig als Gleitlagerwerkstoffe für tribologische Anwendungen eingesetzt. Zusammen mit den Elementen Al und Zn ergeben sich sehr gute tribologische Eigenschaften von Gleitlagern. In der diesem Beitrag zugrunde liegenden Studie wurden die Verschleißeigenschaften von Gleitlagern aus SnPbAlZn, reinem Sn, reinem Pb, reinem Al und reinem Zn untersucht. Die Experimente wurden mittels Untersuchungen in Abständen von 30 min bei einer gesamten Versuchszeit von jeweils 150 min in einem Radialprüfstand für Gleitlager ausgeführt. Als ein Ergebnis stellte sich heraus, dass die Verschleißeigenschaften durch Wahl des Werkstoffes verbessert werden können.
