    摘要： In a manufacturing method for a grinding wheel in which a plurality of wheel chips each composed of an abrasive grain layer containing superabrasive grains and a foundation layer are adhered to a core attached to a wheel spindle carried by a wheel head of a grinding machine to be drivingly rotatable about a rotational axis and in which a grinding surface formed on the abrasive grain layers grinds a workpiece, drivingly rotatably supported by a workpiece support device of the grinding machine, in contact at a grinding point, the method forms green wheel chips each having opposite ends in a wheel circumferential direction inclined relative to the wheel circumferential direction, bakes the green wheel chips to form baked wheel chips, and adheres the plurality of baked wheel chips to the core so that an oblique groove is formed between adjoining abrasive grain layers.

    摘要： In a grinding wheel comprising a disc-like core member and a ring-shape grinding wheel layer wherein superabrasive grains selected from cubic boron nitride particles and diamond particles are contained together with aggregates in a bonding material, the aggregates are made of porous ceramics particles and have an average particle size which is in a range of 70% to 150% relative to the average particle size of the superabrasive grains, and bridges made of the bonding material are formed between the aggregates adjoining to one another or between the aggregates and the superabrasive grains adjoining to the aggregates.

    摘要： A crankpin 1 of a crankshaft rotatably supports a big end of a connecting rod 4 through a sliding bearing 5 fitted therein. The sectional profile of the crankpin 1 takes the form of a polygon whose profile is made of plural arcs of curvature. When the crankpin 1 rotates relative to the bearing 5, the wedge effect is generated to decrease the squeeze loss, a kind of the power loss. And, the oil film thickness between the crankpin 1 and the bearing 5 is secured to prevent the shear loss, another kind of the power loss, from increasing, whereby the power loss can be decreased in total.

    摘要： A plurality of segmented chips are reinforced by applying an adhesive to the circumferentially opposite end portions thereof, and the adjoining segmented chips adjoining in the circumferential direction are adhered to the circumferential surface of a disc-like core with the adhesives at the circumferentially opposite end portions being not jointed with each other. Thus, the segmented chips can be prevented from being loaded with an unnatural force even when the disc-like core with the segmented chips adhered thereto expands and contracts radially due to thermal expansion and thermal contract. Thereby, expansion and contraction of the disc-like core do not impose a compression stress or the like on adhesives situated between adjoining segmented chips.
