摘要： Construction is achieved that is capable of preventing the formation of radial streaks in the tip-end surfaces of teeth of hub-side face splines 21. When a swing center distance is taken to be L, a swing angle that is the inclination angle of the center axis of a roll 30 with respect to a main hub body 8 is taken to be θ, the pitch diameter of the hub-side face splines 21 is taken to be Dh, the number of teeth of the hub-side face splines 21 is taken to be Nh, and the number of teeth of a processing surface 31 of the roll 30 is taken to be Nr, the position relationship of the main hub body 8 and the roll 30, or in other words, at least one of the swing center distance L, the swing angle θ, and the pitch circle diameter Dh is regulated so that the relationship Nh/Nr=cos θ+(2L/Dh)·sin θ is satisfied.

摘要： A method of manufacturing a die forged crankshaft to be mounted in a two or more cylinder reciprocating apparatus includes: an upsetting step that includes upsetting a billet having a constant cross-sectional area along an entire length thereof to form a blank having an enlarged cross-sectional area at a region between a portion to be formed into a leading crank arm of the crankshaft and a portion to be formed into a trailing crank arm thereof; a die forging step that includes die forging the blank formed in the upsetting step to form a forged blank having a shape of the crankshaft with a flash; and a trimming step that includes trimming the flash from the forged blank formed in the die forging step. This makes it possible to improve the material utilization and to use a billet having a cross-sectional size as small as possible.

摘要： A forged crankshaft production method includes a first preforming step, a second preforming step, and a final preforming step. In the first preforming step, sectional areas of portions to be formed into pins and sectional areas of portions to be formed into journals are decreased, whereby flat portions are formed, and the portion to be formed into the pin located at a second position is decentered. In the second preforming step, a portion to be formed into the pin located at a first position is decentered, and a portion to be formed into the pin located at a third position is decentered to a side opposite to the portion to be formed into the pin located at the first position. In a blank obtained thereby, portions to be formed into pins have been reduced and decentered, and the material yield rate can be improved.

摘要： A forged crankshaft (1) includes a carbon steel containing S, wherein in a portion corresponding to a machined outer circumferential surface of a shaft part such as journals (J), crank pins (P), a front part (Fr), and a flange (Fl), a ratio x/y of an area rate x of sulfide in a position (X) corresponding to a parting surface of a die for finish forging to an area rate y of sulfide in a position (Y) corresponding to a bottom of a die impression of the die for finish forging is equal to or lower than 1.5. The forged crankshaft (1) can avoid an occurrence of machined surface cracks on the journals (J) and the crank pins (P) after the outer circumferential surface is machined.

摘要： In a forming apparatus, journal dies hold and retain rough journal portions of a preform blank therebetween, and reference crank pin die and movable crank pin dies contact rough crank pin portions thereof. In this state, the journal dies and the movable crank pin dies are moved axially toward the reference crank pin die and the reference crank pin die and the movable crank pin dies are moved perpendicular to an axial direction. With this, rough crank arm portions are axially compressed to reduce their thickness to that of crank arms of a forged crankshaft, and the rough crank pin portions are pressed perpendicular to the axial direction to increase an amount of eccentricity to that of the forged crankshaft crank pins. 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.
