一、鍛造曲軸與鑄造曲軸的此較及鑄造材料的选擇曲軸为發动机中極重要的零件。它負有傳遞动力及轉化運动形式的双重任务;为了保证滿意的使用性能,曲轴应該具有足够的耐疲性、抗磨性、以及消震性。曲轴的设计,制造吸性能直接与毛坯的制法有关。曲轴毛坯有鍛的、鑄的兩种,鍛造曲轴充分利用了机械性能具有方向性的纖维组織,而鑄造曲轴的特点在于金属基体中夾有石墨
First, the forged crankshaft and cast crankshaft of this casting material selection and crankshaft for the engine is extremely important parts. It has the dual task of transmitting power and transforming the form of movement. In order to ensure satisfactory performance, the crankshaft should have sufficient fatigue resistance, abrasion resistance and shock absorption. Crankshaft design, manufacturing suction directly related to the system of blank. Crankshaft blank forging, casting two, forging crankshaft take full advantage of the mechanical properties of the directional fiber organization, and casting crankshaft is characterized by the metal matrix with graphite
