摘要
对圆渐开线涡旋型线的齿头修正展开了研究。首先从圆渐开线几何学出发,叙述了涡旋膨胀机的几何模型,探讨了涡旋齿齿头修正方法。为了提高涡旋机械的综合性能,着重分析了型线修正问题,研究了双圆弧修正与双圆弧加直线修正的修正参数的变化规律和修正面积系数的变化规律,为涡旋膨胀机的几何模型研究奠定了基础。
The tooth head correction of the circular involute scroll profile was studied.First,starting from the circular involute geometry,the geometric model of the scroll expander was described,and the correction method of the wrap head was discussed.In order to improve the overall performance of the scroll fluid machine,the problem of wrap profile correction of scroll expander was analyzed.The variation rules of the correction parameters of the symmetrical circular arc shape and symmetrical circular arc plus straightline and the variation rules of the correction area coefficient were studied,which lays a foundation for the study of the geometric model of the scroll expander.
