二、课程设计总结
设计中运用了Matlab科学工程计算软件，用notebook命令调用MS—Word来完成设计说明书及设计总结，在设计过程中用了机械设计手册2.0 软件版辅助进行设计，翻阅了学过的各种关于力学，制图，公差方面的书籍，综合运用了这些知识，感觉提高许多，当然尤其是在计算机软件CAD 方面的运用，深切感到计算机辅助设计给设计人员带来的方便，各种设计，计算，制图全套完成。
由于没有经验，第一次做整个设计工作，在设计过程中出现了一些错误比如线形，制图规格，零件设计中的微小计算错误等都没有更正，设计说明书的排版也比较混乱等等。对图层，线形不熟悉甚至就不确定自己画出的线，在出图到图纸上时实际上是什么样子都不知道 ，对于各种线宽度，没有实际的概念。再比如标注较混乱，还是因为第一次做整个设计工作，没有经验，不熟悉。
这次设计的目的是掌握机械设计规律，综合运用学过的知识，通过设计计算，绘图以及运用技术标准，规范设计手册等有关设计资料进行全面的机械设计技能训练。目的已经达到，有许多要求、标准心中虽然明确理解掌握但是要全力，全面的应用在实际中，还有待于提高水平。
虽然它可能不是良好、优秀，但是既然教学环节、课程设计目的已经达到，那么这次设计做的就是完全合格的。当然还受软件的熟悉，运用程度的影响，所有这些必须得参加实践，接触实际工程设计中才能提高。带轮，齿轮，轴，轴承这些关键的设计计算都达到合格，并且用机械设计手册2.0 软件版的验证了。
通过这次课程设计，感到机械设计综合了力学，公差，材料，制图等学科的知识，要好了这些功课，才能做好机械设计。
