为了设计出传动比函数具有二次不等幅特点的凹凸型非圆齿轮机构，利用自主开发的生成齿廓的软件设计了主动齿轮齿廓，利用 CAD软件优化了内凹部分的曲线。提出了新的齿廓生成方法，利用Pro/E软件仿照展成法原理，用主动轮作刀具、从动轮作毛坯生成从动齿轮齿廓。进行了虚拟仿真，提取了齿轮传动比的理论值。完成了齿轮传动试验，并利用高速摄像机测得了齿轮传动比的试验值。结果显示两组传动比的值基本一致，验证了凹凸型非圆齿轮啮合和传动的正确性及该类齿轮在应用中的可行性。%In order to design a concave-convex non-circular gear mechanism with two-unequal-am-plitude transmission ratio function,the driving gear tooth profile was designed by using the software of self-developed,while the curve of the concave part was optimized by using CAD software.A new method of tooth profile generation was proposed.Pro/E software was utilized imitating generating method to generate tooth profile,using the driving gear as tool gear and the driven gear as gear blank. Virtual simulations were carried out,and the theoretical value of gear transmission ratio was extrac-ted.The tests of gear transmission were completed.The experimental value of gear transmission ratio was measured by using high-speed digital video camera.The results show that the values of the two groups are basically the same.The correctness of the concave-convex non-circular gear in meshing and transmission,and the feasibility of this kind of special non-circular gear mechanism are verified.
