机电毕业设计论文_CA6140型卧式车床传动系统设计及内外传动链分析

CA6140型卧式车床传动系统设计及内外传动链分析Analysis of transmission system of CA6140horizonta l lathe and the internal and external driving chain摘要CA6140型卧式车床的加工对象主要是轴类零件和直径不太大的盘类零件，故采用卧式布局。

为了适应工人用右手操作的习惯和便于观察、测量，主轴箱布置在左端。

车床主轴箱三支承均用滚动轴承，进给箱系统用双轴滑移公用齿轮机构；纵向与横向进给由十字手柄操作，并附有快速电机，该机床刚性好，功率大，操作方便。

经济比较实惠。

本次毕业设计课题主要是对普通车床（CA6140车床）的进给箱内部船动机构进行设计与计算，特别是对传动机构中的齿轮进行了受力计算和校核，对各部分有了较为清晰的认识。

本次所研究的对象是CA6140车床，其主参数为400mm，主参数表示机床的规格大小，是机床的最主要参数，反映机床的加工能力，影响机床的其他参数和结构大小，所以通常以最大加工尺寸或机床工作台尺寸作为参数。

虽然说普通车床的设计研究已经到了极限的状况，但是如果能对平普通车床能做个非常透彻的了解，那么对自己所学的知识就能够达到一个更高的层次，也算是对自己三年来的一个知识的总结。

又由于整个车床的结构相对比较为复杂，所以只选了其中的进给箱部分进行分析和研究，并充分了解了传动原理和传动路线，能够初步理解机床的工作原理，对之前机械的各科专业知识又进行了一次较为全面的复习，基本达到了毕业设计的目的。
