Abstract

684,247. Bearings. GLACIER METAL CO., Ltd. Jan. 8, 1951 [Jan. 23, 1950], No. 1710/50. Class 12 (i). In a journal bearing assembly the bearing or the journal is, in cross-section, of a substantially spiral profile extending over approximately 360 degrees and arranged so that the clearance between journal and bearing decreases from a maximum to a minimum in the direction of oil flow induced by rotation of the journal relative to the bearing, whereby substantially constant pressure of lubricating oil is created all round the journal under conditions in which no external load or force is applied to the journal. In the embodiment shown the bearing comprises two halves 1a, 1b, so machined that the bore 2 is of spiral section, and the variation in bearing clearance may be, for example, from about 0.001 of an inch at A to 0.007 of an inch at B so that the oil pressure created round the bearing under no load conditions is substantially constant. The direction of rotation of the journal is from maximum to minimum clearance and oil is introduced through a passage 1c and a groove 1d at or in the vicinity of the point of maximum clearance. In a further embodiment, Fig. 3 (not shown), the bearing is composed of four segments, bored at different centres and radii so that the bearing is finished with a bore of spiral section. Alternatively, the bore of the bearing may be cylindrical and the journal profiled to provide a spiral section.
