摘　　要：本文针对非圆齿轮传动系，提出了以偏心圆弧段系列设计从动齿轮的理论方法，齿轮节曲线采用 Ｂ样条和最优双圆弧样条综合逼近，并给出了分齿的具体办法。从而解决了任一凸形状的非圆齿轮的设计，减少了工程测绘带来的误差。最后，给出了仿真的结果。s This paper proposes a design theory of slave non circle gear based on sequences of off centered circular segments in connection with non circular gear drive.The pitch curve of non circular gear is approached by B spline curve and bi circular spline curve,and a specific method for teeth dividing is given.Thus the design of the non circular gear with the property of bulge shape is resolved,which decreases the engineering measurement error.Finally the result of relative simulation is developed.
