摘要： Disclosed is a connecting rod bearing for crankshafts having a pair of semi-cylindrical bearings. Circumferential grooves (CG) on the bearing inner surface extend from each circumferential end toward the circumferential center within a maximum circumferential angle of 45 degrees and divide reduced wall thickness region into two sections. Axial grooves communicating with the CG are provided along abutted ends of the bearings. Circumferential length of the CG is larger than that of the reduced region. Depth of the CG becomes gradually smaller from the end toward the center. Width of the CG is not smaller than one-quarter of a diameter of lubricant-oil outlet of internal lubricant-oil passage in a crankpin and less than the diameter. Cross-sectional area of the CG is larger than that of the axial grooves at a connection portion thereof.

摘要： There is provided a sliding bearing, which can continuously enhance conformability even when deformation by high oil film pressure in the vicinity of a central part of the sliding bearing occurs. The sliding bearing includes crownings which are each formed in an inclined shape toward an outer peripheral surface from an inner peripheral surface, at end parts in an axial direction, of an inner peripheral surface of a sliding bearing, so that even when the region in the vicinity of the central part of the sliding bearing 1 receives the oil film pressure and deforms in the recessed shape so as for both the end parts in the axial direction to locally contact a shaft, conformability can be enhanced not only at an early stage of use of the sliding bearing but also continuously by relief by the crownings.

摘要： A half plain bearing which can minimize lubricant leakage while retaining a crush relief function, comprising: grooved portions formed circumferentially on an inner surface of the half plain bearing; protrusions of the grooved portions in a secondary loaded portion being liable to running-in wear caused by contact with a shaft. Consequently, the protrusions undergo running-in wear through contact with the rotating shaft at an early stage. The worn protrusions serve the same purpose as crush reliefs, providing a crush relief function even though no crush relief is formed. This makes it possible to minimize lubricant leakage.

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.
