机械设计及其自动化课程设计万向节传动叉(滑动叉)正文.pdfVIP

南通职业大学毕业设计 万向滑动叉工艺设计 摘 要 万向节滑动叉位于传动轴的端部。它的主要作用：一是传递扭矩，使汽车获 得前进的动力；二是当汽车后桥钢板弹簧处在不同的状态时，由本零件可以调整 传动轴的长短及其位置。零件的两个叉头部位上有两个孔，用以安装滚针轴承并 与十字轴相连，起万向联轴节的作用。零件上的花键孔与传动轴端部的花键轴相 配合，用于传递动力之用。 此次设计是在学完机械制造工艺学及机床夹具设计课程，并进行了生产实习 的基础上完成的。本设计主要编制该零件的机械加工工艺规程，并设计其中一道 工序的专用夹具，并撰写设计说明书。 此次设计培养了我熟悉并运用有关手册、规范、图表等技术资料的能力。进 一步锻炼了我识图、制图、运算、编写技术文件和操作CAD等基本能力。 关键字：万向节滑动叉、工艺、专用夹具 Abstract 1 南通职业大学毕业设计 万向滑动叉工艺设计 Universal joint glide fork is located the drive shaft the nose.Its main function: One, the transmission torque, causes the automobile to obtain the advance thepower;Two iswhen the automobilerear axle of car spring occupies the different condition, may adjust the drive shaft by this components the length and the position. In the components two jaw spothastwoholes,with installstheneedlebearingand isconnectedwith the cross axle, plays the rotary shaft coupling role. On the components colored key hole and the drive shaft nose spline shaft coordinates, to use in transmitting using of the power. This design is in study the machine manufacture technology and the engine bed jig design curriculum, and carried on in the production practice foundation to complete. This design mainly establishes this components the machine-finishing technological process, and designs working procedure the unit clamp, and composes the design instruction booklet. This design trained me to be familiar with and to utilize related technicaldata and so on thehandbook, standard, graph abilities.Further exercised me to know the chart, the charting, the operation, the compilation technology document and operates CAD and so on the basic capability. Keyword: Universal joint glide fork, craft, unit clamp.
