根据正弦函数曲线类比推导出了正弦齿轮的直角坐标方程,利用CAXA电子图板2007的公式曲线功能和Pro/E软件建立了正弦齿轮和流量计的三维模型。为了探究正弦行星齿轮流量计的测量精确性,进行了流量脉动分析,分析结果表明:该流量计比渐开线齿轮流量计具有更小的流量脉动率。
According to the sine function curve analogy, the rectangular coordinate equation of sine gear was deduced. The three-dimensional model of sine gear and flowmeter was established by the formula curve function of CAXA electronic board 2007 and Pro / E software. In order to explore the measurement accuracy of the sine planetary gear flowmeter, the flow pulsation analysis was carried out. The analysis results show that the flowmeter has a smaller flow rate pulsation rate than the involute gear flowmeter.
