Performance Experiments with a 200 mm, Offset Pivot Journal Pad Bearing

Abstract

Journal bearings are an important design option, particularly appropriate for high-speed rotating machinery applications. This paper presents results from an extensive program of experimental work with a 200 mm, five-shoe, tilting-pad bearing of this type. The tilting pads were fitted with offset pivots; this is in contrast to most previous work which has concentrated on bearings with pads which have centrally mounted pivots. The new results obtained for the offset pivot pad bearing are compared with recently published, equivalent results for the same bearing filled with center pivot pads. A substantial temperature reduction in bearing temperature is revealed for the offset pivot case.
