ca6140主傳動(dòng)系統(tǒng)的設(shè)計(jì)

摘要
CA6140車床作為主要的車削加工機(jī)床，廣泛的應(yīng)用于機(jī)械加工行業(yè)中，適用于車削內(nèi)外圓柱面，圓錐面及其它旋轉(zhuǎn)面，車削各種公制、英制、模數(shù)和徑節(jié)螺紋，并能進(jìn)行鉆孔，鉸孔和拉油槽等工作。床身寬于一般車床，具有較高的剛度，導(dǎo)軌面經(jīng)中頻淬火，經(jīng)久耐用。機(jī)床主軸孔徑大，操作靈便集中，溜板設(shè)有快移機(jī)構(gòu)。機(jī)床結(jié)構(gòu)剛度與傳動(dòng)剛度均比較高，功率利用率也比較高，適于強(qiáng)力高速切削。其主軸箱是車床的動(dòng)力源將動(dòng)力和運(yùn)動(dòng)傳遞給機(jī)床主軸的基本環(huán)節(jié)。本設(shè)計(jì)主要針對(duì)CA6140機(jī)床的主軸箱進(jìn)行設(shè)計(jì)，設(shè)計(jì)的內(nèi)容主要有車床運(yùn)動(dòng)參數(shù)的確定、傳動(dòng)方案和傳動(dòng)系統(tǒng)圖的擬定、主要設(shè)計(jì)零件的驗(yàn)算。

Abstract
CA6140 lathe as a major turning processing machine, widely used in mechanical processing industry, suitable for cutting YuanZhuMian inside taper surface and other rotation, face, cutting various metric, imperial, module and thread, and diameter drilling, reaming and heaming work. In general, lathe bed width with high stiffness, guide surface by frequency quenching and durable. Spindle aperture, centralized operation spirit, has moved fast. Machine structure stiffness and stiffness are relatively high, transmission power utilization rate is high, suitable for high speed cutting power. It is the power source of the lathe spindle box will force and motion to the spindle of basic link. This design is mainly for the spindle box CA6140 machine design, design is the main content of lathe movement parameters, transmission scheme and transmission system graph and the main design parts.
  Keywords: CA6140 spindle box parts
