摘　　要：分析了齿轮冷挤压过程中影响齿轮精度的主要因素,提出采用数值分析方法计算齿轮凹模尺寸补偿值的算法和过程。针对某汽车冷挤压齿轮进行了数值分析,得到了齿轮齿顶部分、齿根部分和渐开线部分的凹模补偿值。通过试验对冷挤压加工出的零件进行了影像测量,结果表明,按照数值补偿结果加工出的齿轮凹模可生产出合格的齿轮零件。The major factors that influence the precision of gear manufacturing during the process of cold extrusion have been analyzed.And the numerical analysis arithmetic and process which are used to calculate the size compensation of gear female die are put forward.Numerical analysis is made to the cold-extruded gear,from which the size compensations of die which forms the addendum,the dedendum and the involute part of the gear are obtained.By test,size of the components obtained with cold extrusion is obtained,the results show that that an eligible gear can be produced with the female die which is machined with the numerical compensation method.
