The stability of ordinary journal bearings is found to increase by the use of multi-lobes. Studies have shown that performance can be further improved by incorporation of pressure dams into these bearings. This paper analyses the performance of a four-lobe pressure-dam bearing which is produced by incorporating two pressure dams on the upper two lobes and two relief-tracks on the lower two lobes of...
This paper analyzes the dynamic behavior of a new type of bearing, namely, four-lobe pressure-dam bearing. It is produced by incorporating two pressure dams in the upper two lobes and two relief tracks in the lower two lobes of an ordinary four-lobe bearing. The characteristic curves of this type of bearing show that it is much more stable as compared to an ordinary four-lobe bearing. A study of the...
