鉴于已有的高速水稻插秧机中的椭圆齿轮行星系分插机构在取秧过程中易出现伤秧、插秧过程中易出现倒秧或插不进秧的情况，借助于计算机辅助软件对双偏心卵形齿轮行星系在高速水稻插秧机旋转式分插机构上进行了应用研究，提出了以标准卵形齿轮节曲线和标准直齿圆柱齿轮渐开线作为基础，对无函数表达式节曲线的双偏心卵形齿轮行星系各项参数进行理论分析，建立双偏心卵形齿轮行星系的实体模型，为了将其与插秧机上其他零部件进行装配，给出了双偏心卵形齿轮行星系旋转式分插机构虚拟制造结果。对改装后的插秧机分插机构的虚拟样机进行仿真，与椭圆齿轮行星系分插机构在插秧性能方面进行比较。结果表明：由于双偏心卵形齿轮相对于标准椭圆齿轮的设计变量多，因而结构优化更灵活，安装在插秧机上稳定性好。因此，双偏心卵形齿轮行星系分插机构比椭圆齿轮行星系分插机构更能满足在高速化条件下插秧轨迹的要求。

Rice seeding may be hurt during being taken ,and may be upside-down or may not be easily inserted into the soil during being transplanted , which often occur in high-speed rice transplanters equipped standard elliptical-gear planetary system transplanting mechanism.In view of this situation, transplanting mechanism with the double eccentric oval-gear planetary system equipped in high-speed rice transplanters is studied by means of computer-aided software . Based on the standard oval-gear pitch curves and standard cylinder gear involutes , the parameters of double eccentric oval-gears planetary with functional-free pitch curve are analyzed .The solid model of the double eccentric oval-gear planetary system is established .In order to assemble it with other parts of the rice transplanter , its virtual manufacturing structure at rotary transplanting mechanism is given .The modified virtual prototyping of transplanting mechanism is simu-lated and compared with the existing standard elliptical-gear planetary transplanting mechanism in the performance of the rice transplanter .The results show that the developed new model meets better the requirements of planting trajectory in high speed condition , for the double eccentric oval-gear planetary system has more design variables , more flexible in structure optimization and good stability .
