摘要： 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.

摘要： Provided is a sliding member comprising: a steel back metal layer; and a sliding layer including a porous sintered layer and a resin composition. The porous sintered layer includes Fe or Fe alloy granules and a Ni—P alloy part functioning as a binder for binding the Fe or Fe alloy granules with one another and/or for binding the Fe or Fe alloy granules with the steel back metal layer. The steel back metal layer is made of a carbon steel including 0.05 to 0.3 mass % of carbon, and includes: a non-austenite-containing portion having a structure of a ferrite phase and perlite formed in a central portion in a thickness direction of the steel back metal layer; and an austenite-containing portion having a structure of a ferrite phase, perlite and an austenite phase formed in a surface portion of the steel back metal layer facing the sliding layer.

摘要： Provided is a sliding member having a steel back metal layer and a sliding layer. The sliding layer includes a resin composition and a porous sintered layer including Fe or Fe alloy phase particles and a Ni—P alloy phase functioning as a binder. The steel back metal layer is made of a carbon steel including 0.05 to 0.3 mass % carbon and includes a ferrite phase and a pearlite phase. A central portion in a thickness direction of the steel back metal layer includes not greater than 30 volume % of the pearlite phase. The steel back metal layer includes a high pearlite phase portion in its surface facing the sliding layer. The high pearlite phase portion includes not less than 50 volume % of the pearlite phase.
