    摘要: PROBLEM TO BE SOLVED: To provide a method and an apparatus for treating broken surfaces of a ductile metal component for treating the broken surfaces so as to perform optimum surface alignment when aligning the broken surfaces of the broken ductile metal component again. SOLUTION: In the method of treating the broken surfaces 51a, 52a of the ductile metal component 50, the broken surfaces 51a, 52a are broken by fitting a half-divided type mandrel in a through hole of the ductile metal component with the through hole, and driving a wedge between the half-divided type mandrel. The broken ductile metal components 50 are held in a separated state so that the broken surfaces 51a, 52a keep a fixed space, and predetermined vibration is applied to at least one of the broken ductile metal components 50 in a direction to intersect the broken direction to eliminate break powder 59 stuck to the broken surfaces 51a, 52a.

    摘要: PROBLEM TO BE SOLVED: To provide a connecting rod capable of preventing reduction of service life of roller bearings as a result of a problem wherein the roller bearings used between the connecting rod and respective journals on a crank shaft easily receive variation of a stress distribution, and receive the instantaneous largest stress sometimes, in an internal combustion engine; and a method of manufacturing the same. SOLUTION: This method of manufacturing this connecting rod 10 includes: forming a substantially cylindrical rough bore at one end of the connecting rod 10; applying one of a compressive load and a tensile load to the connecting rod to at least partially deform the rough bore into a non-cylindrical shape; and machining the deformed rough bore into a substantially cylindrical shape (machined bore 30c, 30d) while the one of the compressive load and the tensile load is applied to the connecting rod.

CONSTITUTION:Six pices of material 4 are assembled in ring form so as to be jointed onto the periphery of a core bar 6, on the installing apparatus having the core bar 6 at the center part, then a pressing plate 7 is installed, and the upper parts (flat surface parts) 8-8 of the spherical part 1 of the material 4 are pressed in the direction of arrows and fastened tightly. Then, the installed plate is layed on a welding board, and the jointing parts of the materials 4 are welded and joined, thus welding is completed. The figure 11 indicates the built-up welding part. After the pressing plate 7 and the core bar 6 are dismounted, the connecting rod is installed onto the machine such as lathe, and the inner diameter of a ring-shaped material 12 is machined into a prescribed dimension R1.
