传动轴说明书.doc

引言 机械制造工业是国民经济最重要的部门之一，是一个国家或地区经济发展的支柱产业，其发展水平标志着该国家或地区的经济实力，科技水平，生活水准，和国防实力，机械制造业是国家经济的装备部，是为国民经济提供装备和为人民生活提供耐用消费的行业，不论是传统产业，还是新兴产业，都离不开各种各样的机械设备，机械制造业的生产能力和发展水平标志着一个国家和地区国民经济现在的文化程度，机械制造工艺的内容极其广泛，它不但包括零件的制造，机械的加工，还有热处和产品的装配等，而机械制造的工业的发展和进步，又在很大程度上取决机械制造技术水平和发展，在科学技术高度发展的今天，现代工业对机械制造技术提出了越来越高的要求，推动机械制造技术向前不断发展，而且科学技术的发展也为机械制造技术的发展提供了机遇和发展，由于社会在不断向前发展，一些先进的技术不断进入到机械行业的领域中。我们不但要有先进的设备，还要有先进的工艺参数，还要有优质的人才，否则一切都是白费， 机械加工工艺设计在零件的加工制造过程中有着重要的作用，工艺性的好坏，直接影响着零件的加工质量及生产成本，在设计中为了适应小批批量的生产情况，以提高产品的生产效率，在设计中所采用的零件尽量采用标准件，以降低产品的生产费用，本说明书是关于传动轴的一个简单设计工艺过程，一方面它使我们懂得了传动轴的作用以及一些加工的基本要领，还让我们明白了精度要求对于一个机械加工行业说是多么重要，另一方面，它使我们在机械加工，机械制造行业不断的积累经验和知识，能够让我们早日研制新的产品，实现我们经济的腾飞 目 录 引言···········································································1 摘要···········································································3 关键词·········································································3 一、零件的作用·································································3 二、零件图分析·································································3 三、选择毛坯···································································4 四、锻造的方法及选择···························································4 五、毛坯确定···································································5 六、工艺分析···································································5 七、加工余量···································································5 八、零件热处理·································································6 九、加工工艺路线·······························································6 十、基准选择原则·······························································6 十一、定位基准选择·····························································7 十二、工艺设备·································································7 十三、机床选择·································································8 总结····································································
