滾齒機(jī)差動(dòng)機(jī)構(gòu)?分度軸及走刀掛輪架設(shè)計(jì)
摘 要：隨著工業(yè)技術(shù)的進(jìn)步，滾齒機(jī)的發(fā)展也上升到了一個(gè)新的水平。滾齒機(jī)主要是用于加工圓柱齒輪和蝸輪的，在加工機(jī)床中占有很重要的地位。而現(xiàn)時(shí)我國(guó)的滾齒機(jī)發(fā)展還相對(duì)落后，極大限制了整個(gè)工業(yè)生產(chǎn)力水平的提高，所以我們必須對(duì)其進(jìn)行設(shè)計(jì)改造。
課題研究的主要內(nèi)容是滾齒機(jī)的差動(dòng)機(jī)構(gòu)、分度軸及走刀掛輪架。滾斜齒時(shí)就要使用差動(dòng)機(jī)構(gòu)，差動(dòng)機(jī)構(gòu)位于齒輪箱的側(cè)面，側(cè)面最上方的方頭上是機(jī)床工作臺(tái)的光杠，方頭下面第一個(gè)軸就是差動(dòng)掛輪的主動(dòng)軸。而傳動(dòng)箱內(nèi)裝有主傳動(dòng)進(jìn)給差動(dòng)機(jī)構(gòu)構(gòu)件和走刀掛輪架及分度軸部件，設(shè)計(jì)出的分度軸能滿足加工要求，保證加工精度，且滿足強(qiáng)度、剛度、壽命、工藝性與經(jīng)濟(jì)性等方面的要求。
關(guān)鍵詞：滾齒機(jī)；分度軸；走刀掛輪架；差動(dòng)機(jī)構(gòu)
Design of Differential Motion Mechanism and the Dividing Spindle and the Gear Swing Frame for Feeding of the Gear-hobbing Machine
Abstract: Along with the industry technology progress, the gear-hobbing machine development also rose to a new level. The gear-hobbing machine mainly is uses in processing the cylindrical gears and the worm gear, in processes the machine hold the very important status. But at present our country's gear-hobbing machine development relatively is also backward, the entire industry productive forces level has been enormously limited, therefore we must carry on.
The main issue is the differential motion mechanism, the gear swing frame for feeding and the dividing spindle.Helical rolling will have the use of the differential motion mechanism,it is located in the side of the gearbox,the top side of the square head is a machine tool table light bars,square head is below the first axis of the active differential gear shaft.And there are the differential transmission, the dividing spindle, and the gear dividing swing frame in the gear box., The dividing spindle must satisfy some demands, such as intensity, rigidity, life, movement stability, structure rationality, convenience in loading and unloading, machining precision.
Key words: Gear-hobbing machine; the dividing spindle; the gear swing frame for feeding;Differential motion mechanism
