摘　　要：利用View Cast数值模拟软件对齿轮重力铸造凝固过程进行分析,对齿轮在凝固过程中可能出现的缩松、缩孔等缺陷进行预测,从而制定出工艺优化方案。研究结果表明,在齿轮的轮缘处加冒口,同时在轮缘侧面及幅板上加冷铁,可以达到消除和控制缺陷的目的,最终确定合理的铸造工艺方案。ViewCast numerical simulation software was used to analyze the solidification process of steel gear in gravity casting and the shrinkage porosity defects were predicted to design optimization casting process project. The results show that, placing risers on the rim of the gear and placing chillers on the rim and the webs of the gear, the defects can be reduced or eliminated. The optimal casting process project was selected in the end.
