Abstract: The invention provides a bearing device, including a crankshaft, a pair of half bearings each having crush reliefs adjacent to both circumferential ends thereof, a bearing housing having a retaining hole, and one half thrust bearing arranged adjacent to the retaining hole. Each half thrust bearing is configured at least by a bearing alloy layer and a resin slide layer which constitutes a slide surface receiving an axial force of the crankshaft, and thrust reliefs adjacent to both circumferential end portions of the sliding surface so that its wall thickness is made thinner toward the circumferential end surface. A thrust relief length at an inner end portion of the thrust relief positioned on a rear side in the crankshaft rotational direction is formed to be larger than a thrust relief length at an inner end portion of the thrust relief positioned on a front side.

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.

Abstract: The invention provides 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 bearings 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: There is provided a half thrust bearing having a semicircular-ring shape for a crankshaft of an internal combustion engine, including a back metal layer and a bearing alloy layer having a slide surface on which thrust reliefs are formed adjacently to both circumferential end surfaces so that a wall thickness of the half thrust bearing becomes thinner from the slide surface toward the circumferential end surfaces. A thrust relief length L1 of each thrust relief extends over a circumferential angle θ1 from the circumferential end surface toward a circumferential central portion, and is constant between an inside end portion and an outside end portion in a radial direction of the half thrust bearing. A flat surface of each thrust relief includes a first region on the circumferential end surface side and a second region on the circumferential central portion side.
