摘要(Abstract)：

在深入分析涡旋压缩机渐开线齿型端部修正目的的基础上 ,提出了涡旋齿端的基本修正原则 ,得出了齿型的选取依据 ,提出了型线及齿端参数的设计步骤 ,给出了圆弧类修正齿型结构内容积比的通用计算方法。系统研究了三种常用修正齿型的特征 ,并提出了其工程设计方法 ,解决了多自由度修正齿型无法直接设计的工程问题。
Based on the deep analysis of modification of top wraps for scroll machinery, the essential principle of modification is presented,a choosing rule of wraps is summarized,design steps of profiles and top wraps are put forth and a general method to calculate the inner volume ratio of scroll machinery modified by arc-shaped curves is obtained.Properties of three kinds of ordinary modifications are studied carefully,so a convenient, intuitionistic and practical design method is presented.This method is able to solve the problem that modified top wraps with multi-degree of freedom that can't be manufactured directly.
