【摘要】：針對(duì)爪式真空泵現(xiàn)有的爪式轉(zhuǎn)子型線存在不光滑連接點(diǎn)的缺陷,本文提出了一種新型全光滑的爪式轉(zhuǎn)子,其轉(zhuǎn)子型線由6段圓弧和3段擺線的等距曲線組成,且能夠?qū)崿F(xiàn)正確的嚙合;得到了其生成方法和型線方程。通過對(duì)其工作過程進(jìn)行三維數(shù)值模擬,分析了全光滑爪式轉(zhuǎn)子內(nèi)部流場(chǎng)的變化規(guī)律,并與現(xiàn)有的爪式轉(zhuǎn)子進(jìn)行性能對(duì)比。研究結(jié)果表明:所提出的爪式轉(zhuǎn)子具有嚙合性能好、余隙容積小、力學(xué)性能好等優(yōu)點(diǎn)。
[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.
