摘要： Disclosed is a sliding bearing for an internal combustion engine for supporting a crankshaft including a pair of semi-cylindrical bearings combined with each other into a cylindrical body. Each of inner circumferential surfaces of the respective semi-cylindrical bearings includes first and second curved surfaces following two kinds of arcs with different curvatures. The first curved surface is in a region including a circumferential central portion of the inner circumferential surface. The second curved surfaces are in remaining two regions of the inner circumferential surface. The circumferential oil groove and the axial groove communicate with each other. The circumferential grooves of the second curved surfaces and the axial groove communicate with each other. The groove bottoms of the circumferential grooves of the second curved surfaces are displaced to a side of the bearing inner circumferential surface from a groove bottom of the axial groove.

摘要： Disclosed is a sliding bearing consisting of a pair of semi-cylindrical bearings for supporting a crankshaft or a crank pin in an internal combustion engine. The sliding bearing is incorporated in a split-type bearing housing. One of the semi-cylindrical bearings being incorporated in at least one of the pair of housing halves, which one housing half has a relatively higher stiffness, is provided with a number of circumferential grooves on an inner surface of the semi-cylindrical bearing so as to extend circumferentially along the inner surface of the semi-cylindrical bearing. The circumferential grooves existing at least one circumferential end region of the inner surface of the semi-cylindrical bearing have a depth of not less than 10 μm, the circumferential end region including a circumferential bearing end face orientating a direction opposite to the rotation direction of the shaft or pin.

摘要： Disclosed is a cylindrical sliding bearing consisting of an upper and a lower half bearings, which supports a crankshaft of an internal combustion engine. An oil groove is formed circumferentially on an inner surface of at least the upper half bearing. There are provided circumferential grooves formed by boring machining on the overall inner surfaces of the half bearings. Each of the circumferential grooves existing in circumferential both end regions has a larger cross-sectional area than the grooves existing in other regions receiving predominantly operational load when the crankshaft rotates. The upper half bearing is chamfered at a front inner end edge with respect to a rotational direction of the crankshaft supported by the sliding bearing, and the lower half bearing is also chamfered at an inner end edge adjacent to the above front inner end edge, an area of the respective chamfered portion being the same as the 0.15 mm to 0.4 mm length chamfer corner area.
