为了提高涡旋机械的整机性能 ,采用对称圆渐开线加直线的方法对涡圈始端型线进行了修正 .建立了对称圆渐开线加直线修正的几何理论 ,推导了啮合阶段的排气腔容积的计算公式 .研究结果表明 :涡圈始端采用对称圆渐开线加直线修正时 ,动、静盘涡圈仍能保证正确地啮合 ;涡圈始端对称圆弧修正是对称圆弧加直线修正的特例 ,而对称圆弧加直线修正又是对称圆渐开线加直线修正的特例
In order to improve the overall performance of the vortex machine, a symmetrical circular involute and straight line method was used to modify the starting end of the scroll wrap.The geometric theory of symmetrical circular involute and straight line correction was established, and the row The calculation formula of gas cavity volume.The results show that when the beginning of the vortex ring adopts the symmetrical circle involute and the linear correction, the dynamic and static vortex circles can still ensure the correct meshing; the initial symmetrical circular arc correction of the vortex ring is the symmetrical circular arc plus Linear correction of the special case, and the symmetrical arc plus linear correction is a special case of symmetrical circular involute and linear correction
