滾齒機總體及傳動系統(tǒng)設(shè)計摘要：齒輪加工機床是機械制造工業(yè)中的一種重要的技術(shù)裝備，技術(shù)含量高且結(jié)構(gòu)復(fù)雜，滾齒機又是齒輪加工機床中應(yīng)用最為廣泛的一種，因此我們必須重視滾齒機的發(fā)展，不斷改進技術(shù)，使之達到國際領(lǐng)先水平。本文主要論述了滾齒機的發(fā)展現(xiàn)狀、發(fā)展趨勢及滾齒機在工業(yè)生產(chǎn)中的作用。主要設(shè)計任務(wù)是滾齒機機床總體結(jié)構(gòu)、傳動方案的設(shè)計。主要設(shè)計內(nèi)容包括：機床總體方案和機床工藝范圍的確定，機床傳動系統(tǒng)設(shè)計，機床總體結(jié)構(gòu)設(shè)計，以及冷卻裝置總成設(shè)計和床身零件的結(jié)構(gòu)設(shè)計等。本機床主要有四條傳動鏈：主運動傳動鏈，展成運動傳動鏈，進給運動傳動鏈和附加運動傳動鏈，對每個傳動鏈的傳動比進行分配，并通過掛輪對機床進行調(diào)整。設(shè)計的目標是使得機床能滿足強度、剛度、壽命、工藝性與經(jīng)濟性等方面的要求，且運行平穩(wěn)，工件可靠，結(jié)構(gòu)合理，裝卸方便，便于維修與調(diào)整，最后能滿足加工要求，保證加工精度。關(guān)鍵詞：滾齒機；傳動鏈；總體設(shè)計；冷卻裝置；床身Gear-hobbing machine system design and transmission system designAbstract: The gear machine tool is one kind of important technical equip in the machine manufacture industry, the technical content is high and the structure is also complex, the gear-hobbing machine also is a machine equipment which is applies the most widespread, therefore we must take the attention of the development of the gear-hobbing machine, improves the technology, enables it to achieve the international leading level. This article mainly elaborated the development of the gear-hobbing machine at present situation and the trend of development and the gear-hobbing machine in industrial production. The most important task is to design bed structure and transmission plan of gear-hobbing machine. The main design content includes: The engine bed system design, designs the engine bed overall structure, definite engine bed technology capability. The engine bed transmission system design, this machine has four transmission chains: The main movement transmission chain, unfolds movement transmission chain, the feed motion transmission chain and the attached motion transmission chain, needs to design each transmission chain the velocity ratio assignment. As well as cooling system unit design and lathe bed components structural design. The design enables the machine to satisfy such requests as intensity, rigidity, life, process and efficiency , moreover, it demands steadily movement, work piece is reliable, reliable clamping and structure, loading and unloading is convenient, repairing and adjustment is easy, finally can satisfy the processing request, guarantees processing precision.
