The conical fluid film hybrid journal bearing may be developed as a modification to overcome the adverse effects of cylindrical journal bearing configuration. Hybrid bearing also have a capability to take advantage of simultaneous hydrodynamic and hydrostatic action. This paper aims to study analytically the performance characteristics of a non-recessed, worn hybrid conical journal bearing compensated with constant flow valve as restrictor. The Reynolds equation for conical bearing is developed in spherical coordinate system for governing the flow of iso-viscous incompressible fluid in the clearance space of conical journal and bearing and it is solved by finite element method together with restrictor flow equation. Numerically simulated results indicate that appreciable change in the performance characteristics of worn hybrid conical journal bearing with change in speed parameter and they are expected to be quite useful for the bearing designer.
