Benchmarking av temperatur och friktion i axialkullager smörjt med ett nytt polymerbaserat fett (Swedish)
Abstract [en]

This project concerns the benchmarking of a novel polymer thickened grease with a lithium thickened one. The new grease has shown low temperature property in the previous bearing tests on SKF-R2F. A DAQ interface was implemented using lab View for a modified four-ball machine. The result shows the temperature and friction torque profiles of the greases at different speeds. The raw data is attached with a suggested improvement for friction measurement.

Abstract [sv]

Det här projektet avser att jämföra ett nytt polymerbaserat fett med ett lithiumbaserat fett. Det nya fettet har påvisat låga temperaturegenskaper i det tidigare testet med ett lager av typen SKF-R2F. Ett DAQ-gränssnitt implementerades med Lab View för en modifierad fyr-kulig maskin. Resultaten visar temperaturer och friktionsmoment av fetterna vid olika hastigheter. Förslag på förbättring av friktionsmomentet är presenterat tillsammans med rådata.
