| description | To provide a crank shaft capable of reducing friction between a second main journal and a third main journal, and a method for setting a position of a counterweight.SOLUTION: A crankshaft 1 is for an in-line three-cylinder engine. Seen from an axial direction of a rotation axis X, a phase of a reference line extending downward from the rotation axis X is defined as a reference position B, a phase of a straight line connecting the rotation axis X and the center of gravity of a third counterweight 5c is defined as a third weight position C, and a phase of a straight line connecting the rotation axis X and the center of gravity of a fourth counterweight 5d is defined as a fourth weight position D. The third weight position C is set on the advance angle side and the fourth weight position D is set on the retard angle side with respect to the reference position B.SELECTED DRAWING: Figure 1
【課題】２番メインジャーナル、３番メインジャーナルのフリクションを低減可能なクランクシャフト、カウンターウェイトの位置設定方法を提供することを課題とする。【解決手段】クランクシャフト１は、直列３気筒エンジン用である。回転軸Ｘの軸方向から見て、回転軸Ｘから下方向に延在する基準線の位相を基準位置Ｂ、回転軸Ｘと３番カウンターウェイト５ｃの重心とを結ぶ直線の位相を３番ウェイト位置Ｃ、回転軸Ｘと４番カウンターウェイト５ｄの重心とを結ぶ直線の位相を４番ウェイト位置Ｄとする。基準位置Ｂに対して、３番ウェイト位置Ｃは進角側に、４番ウェイト位置Ｄは遅角側に、各々設定される。【選択図】図１ |
