    摘要： 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.

    摘要： A half thrust bearing includes a sliding surface for receiving an axial force of a crankshaft of an engine, and a rear surface on an opposite side thereto. The sliding surface includes a flat surface portion near a circumferentially central portion, and two inclined flat surface portions on both circumferential sides of the flat surface portion. The axial distance between the rear surface and the sliding surface is maximum at the flat surface portion. At any radial positions, the axial distance in each inclined flat surface portion is maximum on a circumferentially central portion side and is reduced toward a circumferential end portion of the half thrust bearing. Each inclined flat surface portion is arranged to form one constant thickness portion extending linearly from a radially inner end to a radially outer end at a circumferential angle of 45°.

    摘要： The invention relates to a method for producing a sliding bearing composite material (10), having a support layer (14), in particular made of steel, a bearing metal layer (18) made of a lead-free aluminum base alloy containing magnesium, and a running layer (22), wherein the aluminum base alloy ultimately comprises 0.5-5.5% by weight magnesium, optionally one or more alloy components from the group comprising zinc, copper, silicon, iron, manganese, chromium, titanium, zirconium, vanadium, nickel, cobalt, cerium, and alloy components resulting from impurities, the sum of the latter not exceeding 1% by weight, and the remainder being aluminum, wherein the aluminum base alloy is copper-free or contains at most 3% by weight copper, the total content of zinc, copper, and nickel does not exceed 8% by weight, and the total content of all alloy components does not exceed 12% by weight. The bearing metal layer (18) is either rolled directly onto the support layer (14) or roll-cladded beforehand with an intermediate layer (38) made of an aluminum alloy or technical pure aluminum and then rolled onto the support layer (14) with this intermediate layer (38) in between, in such a way that the intermediate layer (38) subsequently has a thickness of at most 100 μm, in particular at most 50 μm, wherein the composite of the support layer (14) and the bearing metal layer (18) thus obtained is soft-annealed at temperatures between 280° and 350° C. for 2 to 10 hours so that the bearing metal layer of the composite has a Brinell hardness of 50-80 HB 1/5/30. The running layer (22) is subsequently applied galvanically or by means of a PVD method to the bearing metal layer (18).

    摘要： A crankshaft bearing support structure includes a cylinder block having a first holding portion; a first plain bearing held by the first holding portion of the cylinder block; a crank cap fastened to the cylinder block, the crank cap having a second holding portion; a second plain bearing held by the second holding portion of the crank cap; and a crankshaft having an axis of rotation, the crankshaft being rotatably held by the first plain bearing and the second plain bearing and configured to receive an explosive load from a piston via a connecting rod. The crankshaft flexes, when subjected to the explosive load, in a direction of the explosive load. The crank cap in provided with a mechanism which causes the second holding portion to flex in a manner that a bearing holding surface of the second holding portion follows flexure of the crankshaft subjected to the explosive load.

    摘要： The invention relates to a bearing cover (3) for a split bearing arrangement (1) which comprises a bearing block (2) in addition to the bearing cover (3), and the bearing cover (3) has clamping surfaces (4) which lie against co-operating clamping surfaces (5) of the bearing block (2) when the bearing arrangement (1) is in the assembled state, and a first radially inner bearing support surface (12) having an at least approximately curved cross-section as viewed in the axial direction is provided between the two clamping surfaces (4). An additional surface (15) is provided between at least one of the clamping surfaces (4) and the first radially inner bearing support surface (12) which directly adjoins the first radially inner bearing support surface (12) and clamping surface (4) and which is disposed at an obtuse angle (16) to the first radially inner bearing support surface (12) and at an acute angle (17) to the clamping surface (5).

    摘要： A slide bearing configured to support a crankshaft or a crankpin includes: a halved upper bearing body which is disposed on the upper side in an up-and-down movement direction of a piston; and a halved lower bearing body which is disposed on the lower side in the up-and-down movement direction. The upper bearing body includes an upper sliding surface having an upper oil groove disposed along a circumferential direction of the upper sliding surface at a central portion in an axial direction of the upper sliding surface. The lower bearing body includes a lower sliding surface that configures, along with the upper sliding surface, a cylindrical sliding surface that rotatably supports the crankshaft or the crankpin through an oil film, and the axial width of the lower sliding surface is narrower than the axial width including the oil groove of the upper sliding surface.
