滾齒機差動機構(gòu)?分度軸及走刀掛輪架設(shè)計
摘 要：隨著工業(yè)技術(shù)的進(jìn)步，滾齒機的發(fā)展也上升到了一個新的水平。滾齒機主要是用于加工圓柱齒輪和蝸輪的，在加工機床中占有很重要的地位。而現(xiàn)時我國的滾齒機發(fā)展還相對落后，極大限制了整個工業(yè)生產(chǎn)力水平的提高，所以我們必須對其進(jìn)行設(shè)計改造。
課題研究的主要內(nèi)容是滾齒機的差動機構(gòu)、分度軸及走刀掛輪架。滾斜齒時就要使用差動機構(gòu)，差動機構(gòu)位于齒輪箱的側(cè)面，側(cè)面最上方的方頭上是機床工作臺的光杠，方頭下面第一個軸就是差動掛輪的主動軸。而傳動箱內(nèi)裝有主傳動進(jìn)給差動機構(gòu)構(gòu)件和走刀掛輪架及分度軸部件，設(shè)計出的分度軸能滿足加工要求，保證加工精度，且滿足強度、剛度、壽命、工藝性與經(jīng)濟性等方面的要求。
關(guān)鍵詞：滾齒機；分度軸；走刀掛輪架；差動機構(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
