    Abstract: A split-type sliding bearing for a crankshaft in an internal combustion engine incorporated in a split-type bearing housing. The sliding bearing consists of a pair of semi-cylindrical bearing bodies combined with each other to form a cylindrical body. The bearing housing has a cylindrical bearing retaining bore and consists of a pair of housing halves. One of the housing halves has a relatively lower stiffness, and the other has a relatively higher stiffness. One of the bearing bodies is held by the housing half having a relatively lower stiffness. The other bearing body is held by the housing half having a relatively higher stiffness. The bearing bodies have an equal outer diameter to each other, and both of the circumferential end parts of one bearing body have a larger thickness than those of the other bearing body prior to incorporation into the housing halves.

    Abstract: Provided is a half bearing constituting a sliding bearing for a shaft member of an internal combustion engine that is unlikely to cause seizure in a sliding surface even if deflection or whirling of the shaft member occurs during an operation of the internal combustion engine. In a half bearing that constitutes a sliding bearing, a plurality of circumferential-direction grooves are formed to be adjacent to each other in a sliding surface, the sliding surface includes a plane portion that is parallel to an axial line direction and an inclined surface portion that is adjacent to the plane portion, the inclined surface portion is displaced from the plane portion toward an end portion of the sliding surface in the axial line direction such that the sliding surface successively comes close to a back surface, positions of maximum groove depths of the circumferential-direction grooves are located on groove center lines, the groove center lines in the inclined surface portion of the sliding surface are inclined relative to a vertical line toward the end portion of the sliding surface in the axial line direction, a groove inclination angle of the circumferential-direction groove that is the closest to the plane portion is a minimum angle, and the groove inclination angle successively increases toward the end portion of the sliding surface in the axial line direction.

    Abstract: There is provided a bearing apparatus of a crankshaft for an internal combustion engine. The bearing apparatus includes a crankshaft having a plurality of journal portions and a plurality of crank pin portions; a main bearing supporting the crankshaft; and a bearing housing holding the main bearing. The plurality of journal portions include a first journal portion having a lubricating oil passage and a second journal portion not having the lubricating oil passage. The first and second journal portions and are supported by the first and second main bearings and. The bearing housing includes an Al alloy upper housing and an Fe alloy lower housing. The groove depth of the oil groove of the upper half bearing of the second main bearing is one half or less than the groove depth of the oil groove of the upper half bearing of the first main bearing.
