Abstract

When using lubricants in binding machines, the isolation properties of the used lubricants are essential for a failsafe operation of the spot-welding process. Lubricants are applied to the sliding plates to ensure low-friction infeed of the spot-welding arm. In case of over-lubrication, a current transfer results in a reduced functionality of the spot-welding process. Therefore, the isolation properties of the used lubricants have to be considered. The measurement of the isolation resistance and the dielectric strength is suggested for the selection of a proper lubricant. Within this contribution, the isolation properties of thin lubricant film contacts were systematically investigated by measurement of the isolation resistance and dielectric strength. The influence of temperature and humidity present in the insulation fluids and the dependency of the measurement voltage and electrode distance are discussed. The benchmark of a selection of different lubricants clearly indicated the importance of choosing the right lubricant for the specific application.

Zusammenfassung

Beim Einsatz von Schmierstoffen in Bindemaschinen sind die Isoliereigenschaften der jeweiligen Schmierstoffe für einen störungsfreien Betrieb des Punktschweißprozesses entscheidend. Schmierstoffe werden an den Gleitplatten aufgetragen, um eine reibungsarme Zustellung des Punktschweißarmes zu gewährleisten. Allerdings kommt es bei Überschmierung durch die Stromübertragung zu einer reduzierten Funktionalität des Punktschweißprozesses. Aus diesem Grund sind die Isolationseigenschaften der verwendeten Schmierstoffe im Besonderen zu berücksichtigen, und die Messung des Isolationswiderstandes und der Durchschlagsfestigkeit ist für die Auswahl eines geeigneten Schmierstoffes empfohlen. Im Rahmen dieser Studie wurden die Isolationseigenschaften von dünnen Schmierfilmkontakten durch Messung des Isolationswiderstandes und der Durchschlagsfestigkeit systematisch untersucht. Dabei wird der Einfluss von Temperatur und Feuchtigkeit in den Isolierflüssigkeiten und die Abhängigkeit von der Messspannung und dem Elektrodenabstand diskutiert. Der Vergleich einer Auswahl verschiedener Hydrauliköle zeigte deutlich, wie wichtig die Wahl des geeigneten Schmierstoffs für die jeweilige Anwendung ist.
