Abstract
A journal bearing comprises 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. A lateral face is disposed on an end of the body, and extends between the outer and inner surfaces of the body. A feed channel is formed in the lateral face at an acute angle with respect to the planar section and in an inward direction with respect to the axial bore. A first end of the feed channel communicates with the outer surface of the bearing at a location proximate to the planar section, and a second end of the feed channel communicates with the axial bore. A pocket is formed in the inner surface of the bearing in communication with the second end of the feed channel and extends along a substantially helical path from the lateral face of the bearing. At least a portion of the pocket has a width of greater magnitude than a corresponding depth of the portion.
