摘要： A connecting rod bearing for internal combustion engines of a forced-feed lubrication type crank shaft is provided, consisting semicircular bearings. An inner surface of the semicircular bearings is provided with a circumferential groove formed on the inner surface within a maximum circumferential angle range of 45 degrees, measured from one circumferential end facing the same direction as a rotational direction of the crankpin toward a circumferential center region of the semicircular bearing, each of the semicircular bearings having two circumferential ends which are of butt ends brought into contact with those of a mating semicircular bearing. In an assembled state, an axial groove is formed on an inner surface of the semicircular bearings so as to extend along the butt end throughout a full length between both axial ends of the semicircular bearing, whereby the axial groove, as a lubricant-oil flow channel, is connected with the circumferential groove.

摘要： A split-type sliding bearing, for a crankshaft in an internal combustion engine, is comprised of a pair of semi-cylindrical bearings which are fitted between a pair of housing halves having respectively high and low thermal expansion coefficients and constituting a split-type bearing housing, one of the pair of semi-cylindrical bearings being supported on the housing half having a low thermal expansion coefficient, and the other one of the pair of semi-cylindrical bearings being supported on the housing have having a high thermal expansion coefficient. The circumferential end zones of the semi-cylindrical bearing supported on the housing half having a high thermal expansion coefficient have a thickness which is set to be greater than that of the circumferential end zones of the semi-cylindrical supported on the housing half having a low thermal expansion coefficient. The split-type sliding bearing can solve the problem of occurrence of a stepped difference which is caused at the inner surface of the bearing between the abutting end faces of the pair of semi-cylindrical bearings when the temperature of the split-type bearing housing is increased during operation of the internal combustion.

摘要： A connecting rod bearing in which a semi-cylindrical bearing has an inner circumferential groove that extends from an abutting end with respect to another semi-cylindrical bearing toward a circumferential center part of the semi-cylindrical bearing, and is in alignment with an outlet port of a lubricant oil passage, the abutting end being oriented toward the same direction as a direction of relative rotation of the crankpin with respect to the connecting rod bearing. The dimension are sized such that the connecting rod bearing is capable of preventing large size foreign substances from entering into the clearance defined along the inner surface of the connecting rod bearing even though foreign substances, accompanied in the lubricant oil which is fed to the connecting rod bearing from a cylinder block of an internal combustion engine through the journal portion of a crankshaft, is not caused to discharge from the connecting rod bearing.

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.
