OBSERVATIONS ON THE PERFORMANCE OF SELF-ACTING GAS JOURNAL BEARINGS
Technical Report
·
OSTI ID:4037548
Investigations were made of the performance of selfacting, gas- lubricated bearings. A theory for the occurrence of the phenomenon of half- frequency whirl in plain journal hearings is discussed. An evaluation of the stability of these bearings is presented on the basis of different forms of energy contained within the gas film in order to predict the threshold of the whirl instability. A study was also made of moisture condensation in the gas film of bearings under a rotating unbalance load (synchronous whirl). Wide variations in relative humidity, load, L/D ratio, and speed were employed. The results showed a consistent effect due the ratio of bearing load to ambient pres sure. (auth)
