摘要
推导出了涡旋压缩机渐开线型线的双圆弧修正齿的面积和质心的计算公式,并得到了由该齿构成的动静涡旋在不同曲轴转角下所组成的中心腔和各压缩腔轴向投影面积的计算公式,完善了双圆弧修正的几何学,同时得出了不同修正参数及不同排气角下的压缩比的计算公式,对涡旋压缩机的研究和设计有一定的指导作用.
Formulas for evaluation of area and centroid of scroll-wrap are derived for double-arc modification of scroll compressor,and expressions for computing axial projective area of both central chamber and compression chamber at different angular positions of the crank shaft are derived,also.Thus,the geometric theory of double-arc modification,at the same time the equation of compression ratio is gotten for different modificatory parameters and discharging angles,giving a guide for the research and design of scroll compressor.
