车床主轴箱传动系统的设计
[摘要]现代工业离不开制造,在机械工业中使用最多的制造工具就是车床,CA6140车床是一种普遍又方便的车床,也是普通机械设备制造企业所需的设备之一。在机械加工车间中,车床约占据机床总数的一半左右,车床的加工范围很广,主要加工回转类零件,其中包括:外圆、端面、内圆、锥面、螺纹等等。本设计主要针对CA6140车床的主轴箱进行设计。车床主轴箱是一个比较复杂的传动部件。设计主轴变速箱的结构包括传动件(传动轴,轴承,带轮,离合器和制动器等),主轴组件,纵机构,润滑密封系统和箱体及其联接件的结构设计与布置。
设计的内容主要包括确定车床的主要参数,从而拟定传动方案和传动系统图,计算和校核主要零部件,主轴变速箱装配设计,并且利用专业制图软件进行了零件的设计和处理。

Design of lathe spindle box system
[abstract] Modern industry can not be separated from manufacturing, the most commonly used manufacturing tool in the machinery industry is lathe, CA6140 lathe is a universal and convenient lathe, but also one of the equipment needed by ordinary mechanical equipment manufacturing enterprises. In the machining workshop, the lathe accounts for about half of the total number of machine tools, the lathe processing range is very wide, mainly machining rotary parts, including: outer circle, end face, inner circle, cone, thread and so on. This design mainly aims at the spindle box of CA6140 lathe. Lathe spindle box is a more complex transmission component. The structure of the designed spindle gearbox includes transmission parts (transmission) Structural design and layout of moving shaft, bearing, pulley, clutch and brake, spindle assembly, longitudinal mechanism, lubrication sealing system and box and its couplings.
The contents of the design mainly include determining the main parameters of the lathe, so as to draw up the transmission scheme and transmission system diagram, calculate and check the main parts, and the assembly design of the spindle gearbox. And the professional drawing software is used to design and deal with the parts
