AI Summary & Key Takeaways
AI InsightThe results show that the value of the friction factor of the bearings decreased with increasing bearing pressure.
📌 3 Key Takeaways
Abstract
The zinc-aluminum based ZA-27 alloy was produced by permanent mould casting. Using this alloy and bronze obtained from commercial sources, thin wall journal bearings were manufactured by machining. The friction behavior of the bearings was determined by testing the bearings in a journal bearing test machine under different operating conditions. The results show that the value of the friction factor of the bearings decreased with increasing bearing pressure. It was also observed that the friction factor decreased with increasing bearing clearance. Scanning electron microscope examinations of the ZA-27 bearing operating surface showed that adhesive type wear had an effect on ZA-27 plain bearings.
