本科毕业论文题目名称：复合行星齿轮变速器传动比的分析与计算方法的探讨学 院：专业年级：学生：班级学号：指导老师：二 XXX 年 六 月 十 日摘要通过实际调研，汽车自动变速器的结构复杂，工作过程难于理解，主要是因为该类型变速器传动比的分析与计算较为复杂。本文从阐述辛普森式和拉维奈尔赫式两大典型行星齿轮机构入手，对行星架与太阳轮和齿圈的三者之间的传动比关系进行了数学推导和论证，使单排行星齿轮机构的传动比计算，转化为一般的定轴轮系计算。其约束行星排仍采纳一般的定轴轮系计算方法，然后将设定值和求出值代入动力排，尽而求出复合行星齿轮机构传递动力时所形成的传动比。此种复合式行星齿轮机构传动比的求解方法较用解联立方程组的求解方法，更为简单方便 ，易于掌握。这对迅速掌握该类型变速器结构原理，提高维修能力，具有十分重要的意义。关键词自动变速器；传动比；分析与计算AbstractThrough practical research , for the analysis and calculation of transmission are more complex，the automotive’s transmission structure is more complex than others ,and the work processes is difficult to understand .This paper analyze and study the transmission ratio relationship among the planet 、the sun wheel and the ring gear , so that the single-gear ranked the transmission ratio changes into a general round of the axis of calculation .Boundedby its planetary line still use the general calculation methods of the axis calculation methods, and then we can put the setting value and sought value into the power row, finally calculate the transmission ratio when the complex planetary gear mechanism transfers power. It’s much easier to use the simultaneous equations to solve such compound planetary gear transmission institutions ratio, and we could understand it easily and conveniently. It makes great significance for me to improve the maintenance capacity, as well as to grasp the principle of this type’s transmission structure rapidly.Keywords automatic tra...
