Effect of Load Orientation on the Performance of an Inverted Three-Lobe Pressure dam Bearing

Abstract:

Article Preview

Sometimes the line of action of the load does not pass through the axis of a bearing and is shifted on either side by a few degrees. The effect of load orientation on the stability of an inverted three-lobe pressure dam bearing has been studied in this paper. An inverted three lobe pressure dam bearing is produced by incorporating two pressure dams in the upper two lobes and one relief track in the lower lobe. The result shows that stability of an inverted three-lobe pressure dam bearing supporting either rigid or flexible rotor is increased for the positive values of load orientation i.e. when the load line is shifted in the opposite direction of rotation.
