Abstract
The performance characteristics of externally pressurized hole-entry flexible journal bearings with capillary compensation are studied analytically. The finite element method has been used to solve the Reynolds equation governing the lubricant flow in the clearance space of a journal bearing and three-dimensional elasticity equations governing the displacement field in the bearing shell. The bearing performance characteristics are presented for a wide range of values of deformation coefficient ( C d ) which takes into account the flexibility of the bearing shell. The performance characteristics are compared for two hole-entry bearing configurations for the same values of bearing geometric and operating parameters. An example is also provided to enhance understanding of the effects of bearing shell flexibility on the performance characteristics of the two bearing configurations studied.
