曲轴

曲轴的作用流程,红色部分即为曲轴(图为直列四缸)
Cigueñal desmontable de un motor de 2 tiempos monocilíndrico (Piaggio).
Cigueñal de un motor de barco con 6 cilindros en línea, con 7 apoyos.
Corte de un motor donde se aprecia el contrapeso que toma la cabeza de biela que mueve el cigüeñal.

曲轴(crankshaft)是往复式活塞引擎中,将活塞的直线往复运动的动能转化为旋转动能的部件。曲轴主要是由一根会旋转的长轴构成,为了将往复式的运动转换为旋转运动,曲轴上会有「曲轴臂」或曲轴销部份,其轴心和曲轴的轴心有径向位移,而活塞连杆的较大一端会连到曲轴的曲轴臂或曲轴销。

若在四冲程循环中一般会在曲轴上加装一飞轮,以降低其转矩脉冲特性,有时也会在另一端加上旋转或振动的阻尼器,以减少曲轴上的扭力震动

A crankshaftrelated to crankis a mechanical part able to perform a conversion between reciprocating motion and rotational motion. In a reciprocating engine, it translates reciprocating motion of the piston into rotational motion; whereas in a reciprocating compressor, it converts the rotational motion into reciprocating motion. In order to do the conversion between two motions, the crankshaft has "crank throws" or "crankpins", additional bearing surfaces whose axis is offset from that of the crank, to which the "big ends" of the connecting rods from each cylinder attach.
