Effect of shaft misalignment on the performance of starved porous bearings

Abstract EN

Performance of starved porous journal bearings with misaligned shaft was investigated theoretically under hydrodynamic lubrication condition.

The circumferential boundary condition for the oil film pressure is obtained by applying integral momentum equation to the oil film region in the bearing clearance.

Two types of misalignment, axial (vertical displacement) and twisting (horizontal displacement), are considered.

The analysis is performed on finite length , grooved misaligned bearing for starved inlet conditions.

Effect of different degree of starvation and supply pressure are investigated for a particular misaligned condition.

The results show that the journal misalignment and oil supply pressure have a marked effect on the static characteristics of the bearing.
