1、臥式車(chē)床主軸箱設(shè)計(jì)摘要金屬切削機(jī)床在國(guó)民經(jīng)濟(jì)現(xiàn)代化建設(shè)中起著重大的作用。機(jī)床技術(shù)水平的高低已成為衡量一個(gè)國(guó)家工業(yè)現(xiàn)代化水平的重要標(biāo)志之一。機(jī)床工業(yè)是機(jī)械制造業(yè)的“裝備部”，對(duì)國(guó)民經(jīng)濟(jì)的發(fā)展起著重大作用。本論文設(shè)計(jì)的主軸箱的變速級(jí)數(shù)是12級(jí)，傳動(dòng)比為1.41，轉(zhuǎn)速?gòu)?1.5r/min到1440r/min，加工工件的最大直徑為400mm，。論文對(duì)箱體內(nèi)結(jié)構(gòu)進(jìn)行方案設(shè)計(jì)，并對(duì)傳動(dòng)方案、傳動(dòng)路線(xiàn)進(jìn)行了分析，離合器、帶輪、潤(rùn)滑系統(tǒng)、密封裝置等進(jìn)行了設(shè)計(jì)、計(jì)算及校核。本設(shè)計(jì)的主要內(nèi)容包括：1.運(yùn)動(dòng)設(shè)計(jì)：確定主軸的轉(zhuǎn)速、擬定合理結(jié)構(gòu)式、結(jié)構(gòu)網(wǎng)和
2、轉(zhuǎn)速圖、確定齒輪的齒數(shù)、皮帶輪的設(shè)計(jì)計(jì)算以及實(shí)際轉(zhuǎn)速和標(biāo)準(zhǔn)速偏差的校核等。2.動(dòng)力設(shè)計(jì)：估算各傳動(dòng)軸的轉(zhuǎn)速、估算各軸的直徑、選擇電動(dòng)機(jī)、齒輪強(qiáng)度驗(yàn)算、主軸剛度的校核、軸承壽命的驗(yàn)算、選擇離合器。3.結(jié)構(gòu)設(shè)計(jì)：確定各傳動(dòng)組件的空間布置。關(guān)鍵詞：主軸箱，齒輪，摩擦式離合器32HORIZONTALLATHESPINDLEBOXDESIGNABSTRACTMetal-cuttingmachinetoolinthemodernizationofthenationaleconomyplaysanimportantrole.Thelevelof
