【摘要】：為了減輕特裝重卡傳動(dòng)軸的重量,同時(shí)不降低其強(qiáng)度,對(duì)主要零部件進(jìn)行了重新設(shè)計(jì),對(duì)零部件毛坯的鍛造工藝和機(jī)加工工藝進(jìn)行了重新規(guī)劃。設(shè)計(jì)了萬(wàn)向節(jié)總成,確定了萬(wàn)向節(jié)的規(guī)格,通過(guò)計(jì)算最終確定軸管尺寸為Φ150 mm×7 mm,通過(guò)對(duì)比相關(guān)的性能指標(biāo),對(duì)花鍵軸進(jìn)行了選型,改進(jìn)了端面齒突緣叉和花鍵軸毛坯的鍛造工藝以及花鍵軸的機(jī)加工工藝,最終實(shí)現(xiàn)了特裝重卡傳動(dòng)軸總成輕量化設(shè)計(jì)制造。實(shí)踐結(jié)果表明,在不降低傳動(dòng)軸性能的前提下,通過(guò)減小關(guān)鍵零部件毛坯的下料尺寸,提高了材料利用率,傳動(dòng)軸總成減重6.76 kg,減重8.45%,實(shí)現(xiàn)了傳動(dòng)軸的輕量化設(shè)計(jì)。
[Abstract]:In order to reduce the weight of the drive shaft of the special heavy truck without reducing its strength, the main parts were redesigned, and the forging technology and machining technology of the blank of the parts were replanned. The universal joint assembly is designed, and the specification of the universal joint is determined. the size of the shaft tube is 桅 150 mm 脳 7 mm, and the splice shaft is selected by comparing the related performance indexes. The forging technology of end face tooth protruding fork and splice shaft blank and the machining technology of splice shaft are improved. Finally, the lightweight design and manufacture of special heavy truck transmission shaft assembly is realized. The practical results show that, on the premise of not reducing the performance of the transmission shaft, the material utilization ratio is improved by reducing the blanking size of the blank of the key parts, and the weight loss of the transmission shaft assembly is 6.76 kg, and 8.45%. The lightweight design of transmission shaft is realized.
