| 摘 要： | 研究了具有内、外起始角的变基圆涡旋型线，根据展开角是否在x轴起始，给出两种形式的变基圆外型线方程，并明确给出相对应的内型线方程，推导出偏心距的表达式，分析了两种形式的变基圆涡旋型线方程的关系.对两种形式的变基圆涡旋型线进行双圆弧齿头修正，给出双圆弧修正型线方程，分析两种情况下修正型线方程的关系，并探究修正展角对修正齿头几何形状与压缩比的影响，为变基圆涡旋型线的研究提供了一定的理论基础和应用参考.

| Abstract: | The scroll profile of variable base circles with internal and external starting angles was studied. Based on whether the opening angle started on x axis， the external and internal profile equations of two types of variable base circles were given. The expression of eccentric distance was deduced and the relation between two types of base circles with changing radius profile equations was analyzed. The scroll profile of variable base circles was modified in double arc and the modified profile equations of double arc were given. The relation between two types of modified profile equations was analyzed and the influences of the modified opening angles on the modified tooth profile and compression ratio were explored， which may provide a reference for further studies on variable base circle scroll profiles. |
