一、前言转子型线由各段曲线组成。型线设计、结构参数的选择要求为气密性好、漏气三角形小、接触线长度短、面积利用系数大、工艺性好、转子刚性好。但这些结构参数和各个性能优劣 First, the preface The rotor profile consists of curves of various segments. Type line design, the structural parameters of the requirements of airtightness is good, small leakage triangle, the contact line length is short, large area utilization factor, good technology, good rotor rigidity. However, these structural parameters and the advantages and disadvantages of each performance
