Abstract: A bearing device includes a crankshaft having a plurality of journal portions, main bearings for supporting the crankshaft, and a bearing housing. The plurality of journal portions includes a first journal portion with a lubricating oil passage and a second journal portion without the lubricating oil passage. The first and second journal portions are supported by the first and second main bearings. The bearing housing includes an upper-side housing and a lower-side housing. A length of a crush relief of at least an upper-side halved bearing of the second main bearing is larger than a length of the crush relief of each of upper-side and lower-side halved bearings of the first main bearing.

Abstract: The present invention refers to a crankshaft (1) for an alternative compressor comprising a main shaft (21) connected to an eccentric pin (2) by means of a peripheral flange (3) containing a lubricating hole (24) extending through said eccentric pin (2) and through at least part of the body of main shaft (21), one of the edges of said hole (24) being on the cylindrical surface (2a) of said eccentric pin (2). With this type of hole, the present invention allows for the use of shafts having extremely low diameters (and, as result, with low viscous loss), even with high eccentricities, whereby an excellent capacity of oil pumping and mechanical strength is maintained.

Abstract: A crankshaft for an internal combustion engine can be an integrated crankshaft in which a thrust receiving surface is formed on each of crank arm parts around the root of a crankpin in an annularly protruding manner to restrict axial movement of a connecting rod. A recessed portion is formed in each of the facing surfaces of facing crank webs at a position near a corner portion continuing from the crankpin to the crank arm part, the position being so close to the crankpin that part of the thrust receiving surface is cut away.
