摘　　要：以纯滚动凸圆弧齿轮为研究对象,分析了跑合前不同名义压力角、齿数、齿顶高系数对纯滚动凸圆弧齿轮的齿根弯曲应力的影响规律;分析得出:纯滚动凸圆弧齿轮的齿根弯曲应力随齿轮的名义压力角、齿数增加而减少,随齿轮的齿顶高系数增加而增加。为纯滚动单圆弧齿轮的参数选择提供参考。The pure rolling convex circular arc gear is designed in this paper. The influence rules of different modulus, nomi- nal pressure angle, helix angle, tooth number and the addendum coefficients on the tooth root bending stress of pure rolling convex circular arc gear are studied. It is concluded that the tooth root bending stress decreases with increase of the modulus, the nominal pressure angle and the teeth number, while increases with increase of the helical angle and addendum coefficient. It would provide a theoretical basis for parameters selection of the pure rolling single arc gear.
