Abstract:
A journal bearing comprising:(a) a body having a central longitudinal axis, a cylindrical inner surface coaxially disposed around the longitudinal axis and defining an axial bore, and an outer surface including a peripheral planar section;(b) a lateral face disposed on an end of the body and extending between the outer surface and the inner surface perpendicularly with respect to the planar section of the body;(c) a feed channel formed in the lateral face at an oblique angle with respect to the planar section and in an inward direction with respect to the axial bore, the feed channel having first and second ends, the first end of the feed channel communicating with the outer surface at a location proximate to the planar section, and the second end of the feed channel communicating with the axial bore; and(d) a pocket formed in the inner surface in communication with the second end of the feed channel and extending along a substantially helical path from the lateral face, wherein at least a portion of the pocket has a width of greater magnitude than a corresponding depth of the portion.
