Performance analysis of a multirecess capillary compensated conical hydrostatic journal bearing

The present paper is aimed to study theoretically the performance of a 4-pocket hydrostatic conical journal bearing system. The Reynolds equation governing the flow of lubricant in the clearance space of bearing has been solved using FEM. The bearing static and dynamic performance characteristics have been presented for the values of external load W¯r=0.1–1.0 and for the semi cone angles (γ=10°, 20°, 30° and 40°). The numerically simulated results indicate that the lubricant flow rate is significantly reduced in case of conical journal bearing vis a vis the corresponding similar circular hydrostatic journal bearing.
