Claims

[Claims for Utility Model Registration] 1. A bearing comprising a cylindrical bearing region having an inner surface and an outer surface, the bearing having a gap region between the inner surface of the bearing region and the outer peripheral surface of the shaft neck member. an oil film that surrounds the cylindrical shaft neck member with a close gap therein to support the load, and the bearing region is made of a bearing material having a constant thickness t in the radial direction throughout. the bearing area has a constant radius of curvature r on its inner surface relative to the shaft neck member, and the shaft neck member has a radius of curvature slightly smaller than radius r at its outer periphery so that the bearing region An improvement of a differentially loaded bearing, in which half of said bearing area also has a thickness slightly greater than t, and the radius of curvature of its inner surface is less than r and less than rr. a first circumferential portion which is enlarged and the other half of said bearing area, which is opposite to the first circumferential portion and which has a thickness slightly less than t and has a curvature of its inner surface; a second circumferential portion having a radius greater than r, wherein the first and second circumferential portions of the cylindrical bearing region each have a backing layer, an intermediate layer, and an innermost plating layer having the inner surface. and wherein the first circumferential portion is operatively disposed relative to the shaft-neck member and receives the higher of the different loads, and the second circumferential portion is operatively disposed relative to the shaft neck member and receiving the lower of the different loads, the bearing region comprising a pair of opposing layers comprising the backing layer, the intermediate layer and the innermost plating layer; one of the half shells forms the first circumferential part, the other half of the shell forms the second circumferential part, and the painter's tool A two-split shell type bearing in which the split shells face each other and have end faces for mating, and the mating end faces have the same thickness. 2. A utility model in which the thickness of at least the intermediate layer of the first circumferential portion is greater than the thickness of the intermediate layer of the second circumferential portion to provide a difference in thickness between the two diurnal portions. A split shell type bearing according to registered claim 1. 3 The first circumferential portion and the second circumferential portion in the intermediate layer and the plating layer.
Claims for registration of a utility model, wherein the circumferential portions of the second circumferential portion have different thicknesses, and the thickness of the plating layer of the second circumferential portion is greater than the thickness of the plating layer of the first circumferential portion. The split shell type bearing described in item 1. 4. An increase in the thickness of any of the layers of the first circumferential portion and a concomitant decrease in the radius may be accompanied by a decrease in the thickness of the corresponding layer of the second body portion. A two-split type bearing according to claim 1, wherein the increase in radius is equal and opposite to the increase in radius.
