摘　　要：研制了一种新型非圆齿轮机构,其节曲线是由两种半径的圆弧组合而成。介绍了非圆齿轮机构的结构及其工作原理,并根据几何关系推导了圆弧-圆弧型节曲线参数所需满足的条件。在此基础上设计了齿轮节曲线,并通过修正模数得到了所需的排量。用线切割加工技术制造了齿轮机构样品,与海德曼公司进口齿轮机构在相同条件下进行了对比试验。结果显示,两种齿轮机构的转速扭矩特性基本一致,这表明所提出的设计方法是可行的。A new type of non-circular gear mechanism was developed,whose pitch curve was combined by two kinds of arc with different radii.The structure and working principle of non-circular gear mechanism were described,and the equations which the parameters of arc-arc type pitch curves need to meet were derived according to the geometric relationships.On this basis,the gear pitch curves were designed,and the specified displacement was determined by amending the modulus.A sample of gear mechanism was manufactured by employing wire cutting technology,and was compared with the gear mechanism imported from Hydromech under the same conditions.The results show that the two gear mechanisms have basically the same speed-torque characteristic,which indicates that the proposed design method was feasible.
