Abstract

ABSTRACTThe present comparison is mainly based on the type of restrictor employed in the conical journal bearing with hole-entry in hydrostatic mode. It suggests efficient restrictor to be used in the subjected conical journal bearing. To find the characteristics, Reynolds's equation is applied to the fluid present in the space between conical journal and bearing, the flow equations for various restrictors have been presented using FEM. Different parametric characteristics have been obtained for the range of eccentricity ratio () = 0.1–0.7. The outcome of the comparative characteristics depict the significant variations in the restrictor-based conical hole-entry journal bearing performances in hydrostatic mode which may be useful for the bearing designer to precisely design the conical hole-entry journal bearing. Comparatively, the constant flow valve fitted hydrostatic conical journal bearing with hole-entry may be recommended based on the present study.
