摘要
提出了圆弧型转子有三种不同类型的型线。对于圆弧及其包络线型转子 ,转子齿顶圆半径ra 与两转子中心距a的比值ra/a是一个很重要的参数。推导出该转子曲率半径的公式以及该比值极值的明显表达式。
There are three kinds of various profiles on circular arc is put forward.The ratio (r a/a) of addendum circle radius (r a) of rotor and center distance (a) of two rotors is a very important parameter for circular arc and its envelope rotors.The formula of the rotor curvative radius and obvious expressions of the ratio & extremes are deduced.The wind rate of these various kinds of three lobe circle arc rotor of Roots blower is calculated and comparison of their performance is carried out.
