| 为提高罗茨泵的性能，课题组提出了椭圆旋轮线构成的转子型线，得到了罗茨泵椭圆旋轮线型转子型线的数学模型。分析了椭圆率对转子型线形状的影响，并推导了转子型线的根切条件；然后以容积效率为性能参数对转子型线进行分析研究。结果表明：转子型线的椭圆率越小，容积效率越大；当椭圆率为0.4时，容积效率为0.665 6，比传统摆线型转子型线提高了23.09%，比圆弧型转子型线提高了8.07%。椭圆旋轮线型转子型线性能更好。 |

| In order to improve the performance of Roots pump, a rotor profile composed of elliptic rotor profile was proposed, and a mathematical model of the rotor profile of Roots pump was obtained. The influence of ellipticity on the shape of rotor profile was analyzed, and the root cutting condition of rotor profile was deduced. Then the rotor profile was analyzed with volume efficiency as performance parameter. The results show that the smaller the ellipticity of the rotor profile is, the greater the volume efficiency is. When the ellipticity is 0.4, the volume efficiency is 0.665 6, which is 23.09% higher than that of the traditional pendulum rotor profile and 8.07% higher than that of the arc rotor profile. The performance of the oval wheel rotor profile is better. |
