线段渐开线涡旋压缩机的几何理论

Geometry Theory of Scroll Compressor Made up of Line Segment Involute

从线段渐开线的几何特性和已知涡旋压缩机的主要参数，建立了线段渐开线涡旋压缩机的几何理论，导出了压缩腔容积变化与回转角的关系，推导了涡旋转子上各种气体作用力计算公式。

According to the geometric features of line segment involute and the main parame ters of scroll compressor is established. Relation between volume of compression chambers and rotation angle and various of acting forces on orbiting scroll are also derived.
