Abstract: There is provided a sliding member formed by combining a resin overlay and a soft metal overlay. The sliding member has a soft layer comprising a metallic material with a hardness of less than 40 HV provided under a resin overlay layer comprising a solid lubricant and resin. In the event of contamination by a foreign matter, the soft layer under the resin overlay layer is capable of plastic deformation and the resin overlay layer is capable of partial deformation accompanying the plastic deformation due to the hardness (T1) (μm) of the soft layer and the hardness (T2) (μm) of the resin overlay layer being such that 0.2≤T1/T2≤7.0 and 3.0≤T1≤20.0. Consequently, a foreign matter is desirably embedded and resistance to a foreign matter can be improved. Low friction is maintained by the resin overlay layer even after contamination by a foreign matter.

Abstract: A half thrust bearing having a semicircular shape includes a thrust bearing body having a slide surface that receives an axial force from a crankshaft, and thrust reliefs formed adjacent to respective end portions of the thrust bearing body. Wall thicknesses of the thrust reliefs decrease to the respective end portions. Each thrust relief length continuously increases in a direction from an inner circumference to an outer circumference of the half thrust bearing. Each thrust relief length is a length, in a direction perpendicular to a plane that includes an end portion of the half thrust bearing, from the plane to a point at which a surface of each thrust relief intersects an inner circumference of the thrust bearing body. The half thrust bearing includes a bearing alloy layer and a resin slide layer, or additionally a back metal layer. The slide surface includes the resin slide layer.

Abstract: A thrust bearing for receiving an axial force of a crankshaft of an internal combustion engine. The thrust bearing includes a pair of half thrust bearings having a semi-annular shape that form an annular shape by abutting their circumferential end surfaces. Each half thrust bearing include thrust reliefs formed adjacent to both circumferential end portions of a sliding surface receiving the axial force so that a wall thickness is thinner toward the circumferential end surface. A thrust relief length L2 at an inner end portion of the thrust relief positioned on a rear side of one of the half thrust beings in a rotational direction is larger than a thrust relief length L1 at an inner end portion of the thrust relief positioned on a front side of the other of the half thrust bearing in the rotational direction.

Abstract: A slide member is provided with a metal back, a bearing alloy layer disposed over a first surface of the metal back, and a diamond-like carbon layer disposed at least over a second surface of the metal back, the second surface being located on an opposite side of the first surface. The diamond-like carbon layer has a hardness equal to or less than 1000 HV and when subjected to infrared spectroscopy analysis, exhibits absorption wavenumbers of following wavenumbers (1) to (5) originating from different chemical bonding states: wavenumber (1): 2800-3100 cm−1, wavenumber (2): 1500-1800 cm−1, wavenumber (3): 1200-1500 cm−1, wavenumber (4): 3300-3600 cm−1, wavenumber (5): 730-930 cm−1.The relation (P1+P3)/(P1+P2+P3)≧0.50 is satisfied when an integrated value of absorption rate with respect to wavenumbers (1), (2), and (3) is represented as peak area values P1, P2, and P3, respectively.

Abstract: A resin composition for use in a sliding member, which has higher seizing resistance while maintaining abrasion resistance. The sliding resin composition includes: a resin binder; a solid lubricant; and a protecting and reinforcing agent that is harder and brittler than the resin binder. As the protecting and reinforcing agent, aggregates of particles harder than the resin binder are used. The amount of the protecting and reinforcing agent contained is 1 vol. % or more but 20 vol. % or less of the entire sliding resin composition. The particles harder than the resin binder have an average particle diameter of 10 nm or more but 100 nm or less that is smaller than that of the solid lubricant.

Abstract: The present invention provides a half thrust bearing in a semicircular ring shape for receiving an axial force of the crankshaft of the internal combustion engine, that include a back metal layer, a bearing alloy layer and a resin slide layer, or a bearing alloy layer and a resin slide layer. The resin slide layer constitutes a slide surface receiving the axial force, and the half thrust bearing includes thrust reliefs formed on a side receiving the axial force and adjacent to both circumferential end portions thereof so that a wall thickness of the half thrust bearing becomes thinner toward the circumferential end portions. At least the thrust relief on a rear side in a rotational direction of the crankshaft has a thrust relief length which becomes larger toward an outer end portion from an inner end portion in a radial direction of the half thrust bearing.
