摘要：
In this paper a generalized Reynolds equation suitable for misaligned hydrodynamic journal bearings lubricated by either Newtonian or non-Newtonian ferrofluid is developed. The equation has been solved numerically by the finite difference technique with an appropriate iterative method and the pressure distributions have been obtained. Design charts for all static characteristics (including load capacity, attitude angle, side flow, friction force and misaligned moments) under different misalignment conditions are presented. The effects of misalignment conditions on all these bearing-performance characteristics are analyzed. The results conclude that magnetic lubrication improves, in general, the bearing performance under misalignment.
