1、 减速器输出轴的工艺规程的设计-工序内容设计 摘要 轴类零件是机器中经常遇到的典型零件之一,这主要功用是支承回转零件(如:齿轮, 涡轮,带轮,链轮,联轴器等)并传递运动和动力.传递扭矩和承受载荷。轴类零件是旋转 体零件，其长度大于直径，一般由同心轴的外圆柱面、圆锥面、内孔和螺纹及相应的端 面所组成。按轴的承载情况不同可将其分为:转轴/心轴/传动轴/等.根据结构形状的不 同，轴类零件可分为:直轴、阶梯轴、空心轴和曲轴等。一般机械中,阶梯轴应用最为广 泛。 随着科学技术的发展， 先进设备不断涌现， 机械设计和工艺安排方面有了较的发展， 就目前市场轴的生产水平而言， 大型企业资金雄厚， 拥有先进的技

2、术和生产设备， 而中、 小型企业在工艺安排和夹具设备方面相对较差，通过对细长轴轴零件的工艺分析，运用 数控机床进行加工，提高生产效率、提高产品精度，降低生产成本。所以也希望本次设 计对解决中小型企业这方面的困难有实际作用和意义。 关键词：轴，轴承，绘图，设计，数控技术 减速器输出轴的工艺规程的设计-工序内容设计 II 1 The output shaft of the speed reducer of the technological process design process design Abstract Shaft parts is often encountered in the

3、typical parts, the main function is to support the rotary parts ( such as: gear, turbine ，belt wheel, sprocket, shaft coupling and so on ) and transfer movement and power transmission and torque under load. Shaft is the rotating body parts, its length is greater than the diameter, generally by the c

4、oncentric shaft and the outer cylindrical surface, conical surface, the inner hole and thread and the corresponding end faces. According to the shaft bearing is different can be divided into: shaft / mandrel shaft / etc. According to the structure of the different shape, shaft parts can be divided i

5、nto: straight shaft, shaft, hollow shaft and crankshaft. General machinery of the stepped shaft, the most widely used. With the development of science and technology, advanced equipment is ceaseless emerge in large numbers, mechanical design and process arrangement has a development, on the current

6、market the axis of the production level, large enterprises and strong in financial capital, advanced technology and production equipment, and in small and medium-sized enterprises in the process, arrangement and clamp equipment is relatively poor, the slender shaft shaft parts of the process analysis, use of CNC machine tools for processing, improve production efficiency, improve product accuracy, reduce the cost of production. So I hope this design to solve the small and medium enterprises th
