摘　　要：内齿旋压成形是一种新型的齿轮制造技术,对内齿旋压件成形组织性能的研究不但能丰富旋压成形理论,而且对于指导内齿旋压生产、降低产品的试制成本和提高旋压设备利用率都具有重要意义。本文阐述了内齿旋压用毛坯及内齿件的制取方法,并对原始板坯、内齿旋压用杯形预制坯及内齿旋压件的金相组织进行了分析比较。结果表明,与切削加工不同,旋压成形后,齿轮件出现明显的纤维组织并形成变形织构,使其力学性能得到显著提高。The manufacture methods of the cup-shaped blank and trapezoidal inner gear formed by spinning have been introduced.The metallographic organizations of the original blank, the cup-shaped blank and the inner gear spun workpiece have been analyzed and compared mutually. The results show that the obvious fiber organization and deformation texture are formed in the gear made by spinning, differing from the gear made by cutting, which consequently improving the mechanical properties of the inner tear sDun Darts.
