磁浮列车车载无油润滑涡旋空压机型线端部修正研究

Initial End Modification of the Warps in Maglev Oil-free Scroll Air Compressor

提出一种无油润滑涡旋空压机型线端部修正方法。采用解析法讨论了齿端干涉现象、刀具圆干涉的修正条件、排气泄漏系数和排气平稳性。分析了压缩机的最小修正区域,给出了型线端部修正时的脱啮角、排气角和展角的计算公式。齿端修正结果与样机测绘结果高度吻合,验证了分析的正确性。

A wrap modification used for oil-free scroll air compressor is proposed,and the analytical method is applied to explore the wrap interference,tool circular interference,the leak coefficient and the relationship between the discharge angle and the discharge pressure.Then the minimum modification section is analyzed,the formula about the discharge angle,the exhaust angle and unfold angle is given.The result shows that the circle of modification coincides with the prototype accurately.
