Abstract
The stability of an ordinary journal bearing is found to increase by the use of multi-lobes. The performance can be further improved by the incorporation of pressure dam into these bearing. This paper analyzes the dynamic behavior of a new type of bearing, namely, an inverted three-lobe pressure dam bearing. An inverted three-lobe pressure dam bearing is produced by incorporating a pressure dam in the upper lobe and two relief tracks in the lower two lobes of an ordinary inverted three-lobe bearing. The characteristic curves of this bearing show that it is much more stable as compared to an ordinary inverted three-lobe bearing.
