摘要： In a forming apparatus, movable journal dies (10U, 10B) and stationary journal dies (9U, 9B) hold and retain rough journal portions (Ja) of a preform blank (4) therebetween, and movable crank pin dies (12) contact rough crank pin portions (Pa) thereof, and in this state, the movable journal dies (10U, 10B) and the movable crank pin dies (12) are moved axially toward the stationary journal dies (9U, 9b) and the movable crank pin dies (12) are moved in a direction perpendicular to an axial direction. With this, rough arm portions (Aa) are axially compressed to reduce their thickness to that of arms of a forged crankshaft, and the rough crank pin portions (Pa) are pressed in the direction perpendicular to the axial direction to increase an amount of eccentricity to that of the crank pins of the forged crankshaft.

摘要： In a forming apparatus, journal dies (10U, 10B) hold and retain rough journal portions (Ja) of a preform blank (4) therebetween, and reference crank pin die (11) and movable crank pin dies (12) contact rough crank pin portions (Pa) thereof, and in this state, the journal dies (10U, 10B) and the movable crank pin dies (12) are moved axially toward the reference crank pin die (11) and the reference crank pin die (11) and the movable crank pin dies (12) are moved in a direction perpendicular to an axial direction. With this, rough crank arm portions (Aa) are axially compressed to reduce their thickness to that of crank arms of a forged crankshaft, and the rough crank pin portions (Pa) are pressed in the direction perpendicular to the axial direction to increase an amount of eccentricity to that of the crank pins of the forged crankshaft. Consequently, it is possible to form a blank for finish forging having a shape generally in agreement with a shape of the forged crankshaft for a three-cylinder engine.

摘要： A forged crankshaft includes a plurality of main journals, a plurality of crank pin journals rotatable in a circular path about axes defined by the main journals, and a plurality of crank webs. At least one crank web of the plurality of crank webs defines a middle crank web which is located between and connects two neighboring crank pin journals of the plurality of crank pin journals. The middle crank web has a stress relief forged therein, which is defined by first and second spaced sidewalls, an inner wall and a base wall. The forged-in stress relief has a predetermined depth, wrap angle, radius, and undercut which together define a shape of the forged-in stress relief. The shape of the forged-in stress relief is controlled to reduce stress in the crankshaft.

摘要： A ring member (1) is made of a steel material a rod member (W), which has been rolled so as to have a sectional shape of the ring member (1), with end faces of its opposite ends being joined together. This joining is accomplished by means of a liquid phase bonding such as, for example, welding. The ring member (1) is rendered to be a raw material before a mechanical process is applied for the bearing ring of a rolling bearing assembly. In such case, the ring member (1) has to have an annular groove (3) that is processed to a raceway groove of the rolling bearing assembly. A strengthening treatment through a friction stir welding is applied to a joint (1a) after a rough turning process has been applied to the ring member (1) so as to have a sectional shape resembling to the sectional shape of the bearing ring.

摘要： Es wird ein Verfahren zum Herstellen eines Lagersitzes für ein Halbschalenlager in einem Metallteil offenbart, bei dem das Metallteil durch einen Schmiede- oder Gießvorgang unter gleichzeitiger Ausbildung einer halbschalenförmigen Ausnehmung hergestellt wird, deren Durchmesser etwas kleiner als der des Halbschalenlagers ist. Sodann wird die Ausnehmung durch spanloses Verformen solange bearbeitet, bis der Durchmesser der Ausnehmung dem des Kalbschalenlagers entspricht. Dieses Verfahren zeichnet sich durch sehr geringe Kosten aus und ist darüber hinaus auch bei beengten Platzverhältnissen anwendbar.

摘要： A method for producing a forged crankshaft includes a die forging step, a trimming step, and an excess projecting portion crushing step. The die forging step forms a finish forged blank with flash, the finish forged blank including a shape of the crankshaft, in which crank arms (A) have excess projecting portions (Aaa, Aba) at outer peripheries of side portions (Aa, Ab) thereof near a crank pin (P), the excess projecting portions projecting from the outer peripheries. The trimming step removes the flash from the finish forged blank formed in the die forging step. The excess projecting portion crushing step crushes the excess projecting portions (Aaa, Aba) of the crank arms by pressing the crankshaft using a pair of first dies (10A, 10B), the crankshaft being obtained by removing the flash in the trimming step. With this method, it is possible to conveniently produce a forged crankshaft having reduced weight in combination with sufficient stiffness.

摘要： A method for producing a forged crankshaft includes a die forging step, a trimming step, and an excess projecting portion bending step. The die forging step forms a finish forged blank with flash, the finish forged blank including a shape of the crankshaft, in which crank arms (A) have excess projecting portions (Aaa, Aba) at outer peripheries of side portions (Aa, Ab) thereof near a crank pin (P), the excess projecting portions projecting from the outer peripheries. The trimming step removes the flash from the finish forged blank formed in the die forging step. The excess projecting portion bending step bends the excess projecting portions (Aaa, Aba) of the crank arms toward a journal (J)-side surface of the crank arm (A) by inserting a first die (10) having a U-shape from a direction of eccentricity of the crank pin (P) to the crankshaft obtained by removing the flash in the trimming step. With this method, it is possible to conveniently produce a forged crankshaft having reduced weight in combination with sufficient stiffness.
