INFLUENCE OF WEAR ON THE PERFORMANCE OF FOUR-POCKET/SIX-POCKET CONICAL JOURNAL BEARING SYSTEM COMPENSATED WITH CONSTANT FLOW VALVE RESTRICTOR

摘要

The four-recessed/six-recessed conical hybrid journal bearing offers excellent performance characteristics for axial andradial external load applications. In the present work, an analytical study concerning the influence of wear on theperformance of a four- pocket/six-pocket hybrid conical journal bearing system compensated with a constant flow valve(CFV) compensated restrictor has been studied. The Reynolds equation governing the lubricant flow in the clearancespace of the bearing has been solved using finite element method. The static and dynamic performance characteristicshave been presented for the various values of external radial load, wear depth parameter and for the various values ofsemi-cone angles vis-à-vis four-pocket/six-pocket conical journal bearing. The numerically simulated results of fourpocket/six-pocket suggest that, the performance of the conical bearing is greatly affected by the wear defect.
