摘　　要：为了满足进口拖拉机动力输出轴国产化的使用性能要求,保证国产轴的可靠性,对其进行国产化中间试验研究。从材料选择、加工工艺、热处理工艺等方面着手,首先完成样件的试制生产。对自制样件与进口原厂件进行抗扭断强度和抗疲劳强度等方面的中间对比试验,通过数据对比分析,自制样件的性能指标已完全达到了产品替代的技术要求,国产化样件研制成功。通过课题研究,可进一步完善相关技术数据,为后续其他型号进口拖拉机动力输出轴的国产化研究提供参考。In order to meet the performance requirements of domestically produced power output shafts for imported tractors and ensure the reliability of domestically produced shafts,a pilot study was conducted on their localization.Starting from material selection,processing technology,heat treatment process,and other aspects,the trial production of the sample is completed first.Intermediate comparative tests were conducted on the torsional fracture strength and fatigue strength of self-made samples and imported original parts.Through data comparison and analysis,the performance indicators of self-made samples have fully met the technical requirements for product substitution,and the development of domestically produced samples has been successful.Through this research project,relevant technical data can be further improved,providing reference for the localization research of other imported tractor power output shafts in the future.
