摘 要
實(shí)際應(yīng)用中，車床主要進(jìn)行車外圓、車端面和鏜孔等工作。車削很少在其他種類的機(jī)床上進(jìn)行，而且任何一種其它機(jī)床都不像車床那樣方便的進(jìn)行車削加工。由于車床還可以用來鉆孔和鉸孔，車床的多功能性可以使工件一次安裝中進(jìn)行幾種加工。因此，在生產(chǎn)中使用的各種車床比任何其它種類的機(jī)床都多。
現(xiàn)代機(jī)床正在向高速度化、高精度化、高柔性化、高自動(dòng)化、高可靠性等方向發(fā)展。CM6150型車床是一種中型精密普通機(jī)床， 它具有操作方便，輕巧，結(jié)構(gòu)簡(jiǎn)單，工藝性好，振動(dòng)、噪聲小，加工精度高，生產(chǎn)率高等優(yōu)點(diǎn)。因此它被廣泛的應(yīng)用在各種車間。本設(shè)計(jì)以CM6150機(jī)床為基礎(chǔ)，進(jìn)行了車床中若干部件的設(shè)計(jì)。本設(shè)計(jì)的主要內(nèi)容包括以下三部分：
主軸箱的設(shè)計(jì)，這部分主要包括：總體的設(shè)計(jì)與布局、各傳動(dòng)軸的設(shè)計(jì)及驗(yàn)算、主軸的設(shè)計(jì)及驗(yàn)算、各齒輪的設(shè)計(jì)及驗(yàn)算、主軸箱CAD圖的繪制。
變速箱的設(shè)計(jì)，這部分主要包括：主要參數(shù)的選擇原則，確定個(gè)檔變速齒輪的模數(shù)、齒數(shù)等齒輪參數(shù)。
齒輪計(jì)算和軸的計(jì)算，對(duì)齒輪的接觸強(qiáng)度和彎曲強(qiáng)度進(jìn)行計(jì)算，進(jìn)行軸的設(shè)計(jì)。介紹了軸的結(jié)構(gòu)，軸徑的選擇方法，計(jì)算個(gè)檔位的彎矩，扭矩，并找出軸的危險(xiǎn)截面進(jìn)行強(qiáng)度校核。

Abstract
Lathes are machine tools designed primarily to do turning, facing, and boring. Very little turning is done on other types of machine tools, and none can do it with equal facility. Because lathes also can do drilling and reaming, their versatility permits several operations to be done with a single setup of the workpiece. Consequently, more lathes of various type are used in manufacturing than any other machine tool.
The development of the machine tool has the following tendencies: high velocity, high precision, high automation and high reliability etc. However, The CM6150 is a medium-sized lathe with high precision. It has following advantages such as convenient operating, simple structure, good crafting, low noise and vibration, high manufacturing accuracy, high productivity and so on. So it is widely used in kinds of workshops. The design is based on CM6150 machine, a lathe in the design of a number of components.This design includes three parts below:
Design of the main shaft box，What is involved in this part are: the total layout and design, the design and calculating of each transferring shaft, the design of spindle, design of each gear and the CAD drawing of the spindle box.
Design of the transmission box ，What is involved in this part are: I explained the choosing principle of the main parameters I determined some parameters about gears, for example, the helical angle, the tooth width, the tooth number etc.
Gears ’s calculated and shaft ’s calculated ，I calculated the rigidity and strength about the main gears. I designed shaft and introduced their structure, the choosing method of their radius, I found their hazardous section ,then calculated the rigidity and strength.
Keywords: the main shaft box; the transmission box; transmission
