摘　　要：分析了轮边减速器壳的缩松和缩孔产生的原因 ,依据均衡凝固和大孔出流技术 ,采用热侧冒口浇注与补缩 ,克服了缩孔、缩松、渗漏缺陷 。This paper dealt with the cause of shinkage cavities and dispersed porosity of wheelhub reductor case casting based on proportional solidification principle and large orifice discharge theory.By using the hot side riser and feeding, the defect on shrinkage and leakage were eliminated and remarkably increased the ratio of casting qualification.
