The provided is a bearing device for a crankshaft of an internal combustion engine including: a crankshaft having a plurality of journal portions; main bearings for supporting the crankshaft; and a bearing housing, wherein a range in which the oil groove of the upper-side halved bearing of the second main bearing is formed in the circumferential direction includes at least a range of a circumferential angle of 20° within the ±45° region, a circumferential end portion of the oil groove on a rotationally forward side communicates with the crush relief at a minimum, and is open to a circumferential end face at a maximum, and a circumferential end portion of the oil groove on the rotationally backward side of the journal portion is positioned on a circumferential center portion side of the upper-side halved bearing from a circumferential end face of the upper-side halved bearing.

A sliding bearing includes an inner ring element; an outer ring element; and at least one sliding bearing element, which is arranged between the inner ring element and the outer ring element, wherein the sliding bearing element includes at least two sliding bearing pads, wherein the individual sliding bearing pads each have a bearing surface, which has the basic shape of a spherical cap.

An apparatus and method for assembling a split sleeve onto a shaft. The split sleeve apparatus provides a first and second arcuate portion with each having a partial cylindrical configuration. The first and second arcuate portions have at least one finger extending circumferentially outward from their opposing ends. The at least one finger from each of the first and second arcuate portions complementarily engage one another to form a continuous cylinder. At least one aperture extends longitudinally through the at least one finger of the first and second arcuate portions. A dowel rod extends through the at least one aperture for connecting the first and second arcuate portions to form the cylinder. The first and second arcuate portions are fabricated from a material having heat expansion characteristics that allow the material to expand when heated during assembly and to contract when cooled creating an interference fit with the shaft.

A bearing including a sidewall including a substrate and a low friction material extending along at least one of a radially inner surface or a radially outer surface of the sidewall, the sidewall further including: a body defining a bore about a central axis; and a flange contiguous with and extending from an axial end of the body, where the flange includes a folded over outermost peripheral edge, where the substrate has a reduced thickness at the outermost peripheral edge, the flange being configured such that the substrate is not exposed along the outermost peripheral edge.

A device for assembling a sliding bearing, in particular a spherical bearing, which has an inner ring and a divided outer ring, the device including a clamping ring provided for receiving the outer ring, the inner diameter of the clamping ring corresponding at most to the outer diameter of the outer ring in the maximally compressed state thereof. To shrink the clamping ring onto the outer ring and to detach the clamping ring from the outer ring, a temperature control device, in particular in the form of an induction-heating device, which heats the clamping ring, is provided.

An internal combustion engine, including a pair of opposed pistons, a pair of opposed cylinders, and an output shaft, wherein each of the pistons is arranged for reciprocating motion within a respective one of the cylinders, driven by combustion, and the pistons are coupled to the output shaft by a coupling such that said reciprocating motion of the pistons drives rotation of the output shaft, wherein the coupling includes a connecting rod coupled to the opposed pistons, and the coupling further includes a crankshaft rotatably mounted within a slider bearing, the slider bearing being formed of separable parts and having unitary sides for sliding contact within the connecting rod.

An apparatus and method for assembling a split sleeve onto a shaft. The split sleeve apparatus provides a first and second arcuate portion with each having a partial cylindrical configuration. The first and second arcuate portions have at least one finger extending circumferentially outward from their opposing ends. The at least one finger from each of the first and second arcuate portions complementarily engage one another to form a continuous cylinder. At least one aperture extends longitudinally through the at least one finger of the first and second arcuate portions. A dowel rod extends through the at least one aperture for connecting the first and second arcuate portions to form the cylinder. The first and second arcuate portions are fabricated from a material having heat expansion characteristics that allow the material to expand when heated during assembly and to contract when cooled creating an interference fit with the shaft.

A rotating support device for a torsion beam is be coupled to a support pillar, especially applicable in solar power plant installations which reduces the number of parts used and facilitates the assembly. The device has a clamp which can be coupled to the support pillar having a cylindrical inner area, a bushing intended to be positioned inside the clamp and which has the possibility of rotation together with the torsion beam with respect to the clamp and a retaining part which can be coupled in the slop which in an assembly situation protrudes in height with respect to the central sector of the clamp.

A sliding bearing that is disposed in a cylinder block and supports a journal portion of a crankshaft, including: a semi-annular first split bearing having a first circumferential end surface; and a semi-annular second split bearing having a second circumferential end surface. The first and second circumferential end surfaces contact each other, the first split bearing has a same outer diameter as an outer diameter of the second split bearing, the second split bearing has a thickness at a second circumferentially central position that is greater than a thickness of the first split bearing at a first circumferentially central position, the thickness of the first split bearing is decreased from the first circumferentially central position toward the first circumferential end surface, the thickness of the second split bearing is decreased from the second circumferentially central position toward the second circumferential end surface.

A sliding member includes an overlay layer made of a resin on a side of a sliding surface of a bearing alloy layer. When a valley void volume Vvv (μm.sup.3/μm.sup.2) in the sliding surface of the overlay layer is defined as Vv1, Vv1 is in a range of 0.015≤Vv1≤0.200.
