摘　　要：根据任意转角位置的双圆弧齿轮齿廓数学模型,运用Pro/E软件构建了双圆弧齿轮精确模型,首先分析比较了仅在凸齿处加载和在凸、凹齿处同时加载两种不同加载方式的区别,然后对一系列不同参数的双圆弧齿轮在轮齿的凸、凹齿处同时加载,进行了有限元分析,得出了双圆弧齿轮齿根弯曲应力与螺旋角、模数、齿数的关系曲线。其分析结果将为双圆弧齿轮设计和制造等提供参考依据。Based on the mathematical model of teeth profile of double-circulator-arc gear on any rotary angle position and with the help of Pro / E software a precise double-cireular-arc gear modelis built. Firstly, this paper analyzes and compares the tooth root bending stress under two different loading ways： one is only loading the convex tooth and ansther one is loading the convex and concave teeth. Then a senes of finite element analysis is comducted on the tooth root bending stress of both convex and concave teeth being loaded, therefore a relative curve between the tooth root bending stress of double-circulator-arc gear and the helix angle, modulus, number of teeth is obtained. The results of this analysis will provide a reference for design and manufacturing of the double-circular-arc gear.
