With the development of economy as well as to the learning and introducing foreign advantage technology, lathe industry in China has played a pivotal role in the world. Spindle box is the important part of the lathe and it controlled the power transmission of the whole lathe.Spindle box directly affects the work efficiency of machine tool, thus the importance of the spindle box is goes without saying.This design is mainly for CA6140 lathe spindle box design,and lathe spindle box is a more complicated driving part.According to the current actual situation,considering the factors related to economy and efficiency, to reasonable design idea of lathe spindle box, finally completed the design of lathe spindle box. The major design content including the determination of the parameters, formulate transmission and variable structure scheme and system diagram,transmission design,the estimate and check of?transmission?parts, the?design?of?the?components?structure and the check the spindle component. ?Focus on the parameter?design of gear, belt pulley, bearing and so on, and use the graphics software for designing and processing of the parts. Key words: CA6140 lathe; spindle box; transmission; parts  目录 摘 要 I Abstract II 第一章 绪 论 1 1.1车床的发展及主轴箱的作用 1 1.1.1车床的发展历史 1 1.1.2主轴箱的作用 2 1.2主传动系
