Experimental Vibration Analysis of Cryogenic Treated Shafts Supported by Journal and Rolling Element Bearings

In this study, the effects of cryogenic treatment and tempering on the vibration behaviors of rotating shafts mounted on the rolling element and journal bearings were investigated for the same loading conditions and operating speeds. In this experimental study, the data obtained with the help of proxy probes were analyzed and the results were compared. The results showed that the lowest amplitude values were obtained for the cryogenic treated shaft mounted on the journal bearing. The amplitude values of journal bearing are significantly superior to the rolling element bearings having stability in account
