【摘要】：針對爪式真空泵現有的爪式轉子型線存在不光滑連接點的缺陷,本文提出了一種新型全光滑的爪式轉子,其轉子型線由6段圓弧和3段擺線的等距曲線組成,且能夠實現正確的嚙合;得到了其生成方法和型線方程。通過對其工作過程進行三維數值模擬,分析了全光滑爪式轉子內部流場的變化規(guī)律,并與現有的爪式轉子進行性能對比。研究結果表明:所提出的爪式轉子具有嚙合性能好、余隙容積小、力學性能好等優(yōu)點。
[Abstract]:In view of the defect that the existing claw rotor profile of claw vacuum pump does not only slip at the connecting point, a new type of fully smooth claw rotor is proposed in this paper. The rotor profile is composed of 6 circular arcs and 3 cycloid isometric curves. And can achieve correct meshing; The generation method and profile equation are obtained. Based on the three-dimensional numerical simulation of the working process, the variation of the flow field in the all-smooth claw rotor is analyzed and compared with the existing claw rotor. The results show that the proposed claw rotor has the advantages of good meshing performance, small clearance volume and good mechanical properties.
