摘　　要：为了解决多涡旋齿涡旋机械的关键问题型线构建和型线修正,提出公转中心位置模型,确定两涡旋盘上多条涡旋齿的生成和运动啮合规律,建立任意齿数的多齿啮合型线构建的数学模型,给出常用曲线作为多齿啮合型线的条件,得到多齿啮合型线的构建准则,为直接构建满足正确啮合的新型多齿啮合型线奠定理论基础。以此为依据创建多齿的正多边形渐开线、组合型线和变壁厚型线等多种啮合型线,创建多齿的圆弧修正、圆渐开线修正和组合修正等多种型线修正方法;建立起包含单齿型线在内的多齿啮合型线理论体系。In order to solve the key questions, wrap profile construction and profile modification for multi-wraps scroll machinery, the model of orbiting central position is presented, the generation characteristic and motion meshing law of multiply wraps on two scroll plates are determined, the mathematic model of meshing profile construction for multi-wraps with random wrap numbers is established, the conditions of common curves being used for meshing profile for multi-wraps are given, and the construction criteria of meshing profile for multi-wraps are obtained. The study results lay theoretical foundation for directly constructing new meshing profile which can realize correct meshing. The new multi-wraps profiles such as regular polygon involute, combination profile as well as tapered thickness wrap profile are proposed, and the new multi-wraps profile modification methods including arc profile modification method, circle involute profile modification method and combination curve profile modification method are proposed, too. The theory system of multi-wraps meshing profile including the existing single wrap profile is established.
