传动轴的工艺设计
摘 要
传动轴是组成机器零件的主要零件之一,一切做回转运动的传动 零件(例如:齿轮,蜗轮等)都必须安装在传动轴上才能进行运动及 动力的传动。传动轴的主要作用为,传递力矩和扭矩。传动轴常用于变速 箱与驱动桥之间的连接,这种轴一般较长,且转速高,只能承受扭矩 而不能承受弯矩。应该使传动轴具有足够的强度和高临界转速,在强 度计算中,由于所获取的安全系数较大,从而使轴的尺寸过大,本文 讨论的传动轴工艺设计方法,并根据现代规范增添了些表面处理的方 法比如表面发蓝。主要内容是传动轴的如何选择材料,传动轴的分析和加工 方法的选择,传动轴的加工方案的选择以及如何选择毛坯。通过计算设计出加工 传动轴的加工时间,做到有计划的利用时间去生产提高生产效率。

The drive shaft of the process design
Abstract
Shaft is composed of the main parts of the machine parts, all of the transmission parts motion (for example: gear, gear, etc.) must be installed in the transmission of power to exercise and shaft transmission, often used in the connection between the transmission and drive. The shaft generally is long, and the high speed, can withstand torque not inherit the moment. Should make the shaft has enough rigidity and high speed, strength calculation, because of the large safety factor, thus make shaft dimension, this paper discusses the transmission technology design methods, and according to the current standard added some way of surface treatment. The main content is how to choose the material transmission shaft, drive shaft and the analysis of the choice of processing methods, transmission shaft of the processing scheme selection and how to choose the blank. By calculating the design processing and transmission shaft of the processing time, done in a planned use of time to production to improve production efficiency.
