1、 毕业设计（论文）毕业设计（论文） 题目题目 传动轴的工艺设计传动轴的工艺设计 院系名称 机电工程系 班 级 07 机电 1 班 学生姓名 学 号 指导教师 答辩教师 时 间 2010 年 5 月 10 号 I 摘 要 传动轴是组成机器零件的主要零件之，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 承受弯矩。应该使传动轴具有足够的刚度和高临界转速，传动轴的设计方法是以 材料力学为基础，根据轴的强度计算初定其外径， 根据其所承受的载荷确定热处 理工艺，然后校核临界转
2、速和扭转稳定性。在强度计算中，由于所取的安全系数 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，并根据现行规范 增添了些表面处理的方式比如表面发兰。 关键词：传动轴，零件，刚度，强度，表面发兰 II ABSTRACTABSTRACT Shaft is composed of the main parts of the machine parts, all made rotary motion transmission parts (such as: gears, worm, etc.) must be installed on the transmission shaft to ca
3、rry out the movement and force transmission, drive shaft commonly used in the transmission and drive axle the connection between. This axis generally longer, and high speed, can not bear to withstand torque moment. Should be sufficient to drive shaft stiffness and high critical speed, the drive shaf
4、t of the design method is based on mechanics of materials, according to the intensity calculated initially for the shaft diameter, determined according to the load they bear the heat treatment process, and then check the critical speed and torsion stability. In the strength calculation, Given the large safety factor taken, so that shaft size is too large, the paper discusses the shaft design process, and in accordance with existing norms of surface treatment to add s
