旋涡层
5) multiply wraps
多涡旋齿
1.
The graphical method of wrap profile modification using twin-circular arcs for two,three and four wraps was established,and the general profile modification method using twin-circular arcs for multiply wraps with random wrap number was obtained.
建立了双涡旋齿、三涡旋齿及四涡旋齿的双圆弧修正的作图方法,进而得到了任意齿数的多涡旋齿双圆弧修正的通用方法,并分析了齿形参数的变化对修正齿形特点及压缩机性能的影响。
2.
In order to extend the type of meshing profile of multiply wraps,the regular polygon involute is proposed to form the profile of multiply wraps.
为了拓宽多涡旋齿可用啮合型线的种类,提出正多边形渐开线可作为多涡旋齿的啮合型线,如边数分别为4,8,12…和6,12,18…的正多边形渐开线可作为双涡旋齿和三涡旋齿的型线,得出边数为2iZ(i=1,2,3…)的正多边形渐开线可作为Z涡旋齿的啮合型线。
