【摘要】 随着参与啮合齿轮对数的增加,内外啮合行星机构的配齿条件也会发生变化.同心条件越来越宽松,邻接条件越来越复杂,速比条件越来越容易满足,而装配条件则需要根据参与啮合行星轮对数的奇偶性严格判定.在4个配齿条件中,装配条件最严格,也最易被忽视,应引起足够的重视.将行星机构各构件的装配相位夹角表达式代入相应转速方程,以齿数应满足整数作为约束条件,确保单排行星机构的各构件不相互干涉,确定单星和双星内外啮合单排行星机构的装配条件,进而拓展为每组行星齿轮经过奇数次啮合或偶数次啮合的装配条件.相关结论为工程技术人员在设计内外啮合单排行星机构时,提供了成熟的解决方案.更多还原

【Abstract】 With the increasing of meshing frequency,the teeth matching constraint conditions of commonplane internal-external mesh planetary mechanism were changed.The concentric constraint condition became more and more relaxed,the adjacent constraint condition became more and more complex,the speed ratio constraint condition became more and more easy to be fulfilled,and the assembly constraint condition should be adjusted strictly with the parity of each group gears meshing frequency in the planetary mechanism.Among these constraint conditions,the assembly constraint condition was the strictest,but often tends to be ignored by engineers,which should be considered more seriously.Taking the rotation angle expression of components of planetary mechanism during the assembling process into the rotation equation,and taking the teeth number should be integer as constraint condition,to avoid common-plane internal-external mesh planetary mechanism components interference each other while assembling the planetary mechanism,and the assembly constraint condition of single-pin and dual-pin planetary mechanism were deduced,then the assembly constraint condition of odd-pin and even-pin planetary mechanism were obtained.These conclusions could prove engineers mature solutions when they design common-plane internal-external mesh planetary mechanism.更多还原
