Y3150E型滾齒機(jī)刀架設(shè)計(jì)
摘 要
滾齒機(jī)是齒輪滾刀加工齒輪的專用機(jī)床，在齒輪加工中應(yīng)用最廣泛。在滾齒機(jī)上可切削直齒、斜齒圓柱齒輪。這種機(jī)床使用特制的滾刀時(shí)也能加工渦輪、花鍵和鏈輪等各種特殊齒形的工件。
本滾齒機(jī)由床身、立柱、刀架及滑板、工作臺(tái)組成。滾刀箱固定在刀架滑板上，滾刀心軸插入滾刀主軸并用拉緊螺栓固定在主軸上。為了保證主軸與前軸承的適當(dāng)間隙，前軸承是做成外錐并開(kāi)口。調(diào)整軸承上的兩個(gè)螺母，可以使前軸承做軸向移動(dòng)，使前軸承孔收縮便可消除主軸和軸承間過(guò)大的間隙。
我的課題主要內(nèi)容是滾齒機(jī)刀架系統(tǒng)設(shè)計(jì)：以8mm最大加工模數(shù)為基本參數(shù)，對(duì)滾齒機(jī)刀架進(jìn)行設(shè)計(jì)，擬定總體方案，進(jìn)行結(jié)構(gòu)設(shè)計(jì)，對(duì)主要的零件進(jìn)行設(shè)計(jì)計(jì)算和強(qiáng)度校核。使設(shè)計(jì)的刀架可用于齒輪加工，最后用CAD軟件生成圖紙。

Y3150E Gear Hobbing Machine Cutter Frame Design
Abstract
The gear hobbing machine is special purpose machine tools cutting gear with gear hob and it is widely used.It can be used for machining spur cylindrical gears,helical cylindrical gears.With special hobbing cutter,it could machine worm gears multiple spline and sprocket wheels whose tooth profile are special.
This gear hobbing machine is composed of bed,column,cutter frame,slider,and machine table.Rob cutter frame is fixed on the slide of cutter rack, the hob shaft is inserted into hob spindle and fixed with the draw-in bolt on the main axle. In order to guarantee the spindle and the suitable front bearing gap, the front bearing has the outer cone and the aperture. Adjusting on the bearing two nuts, it causes bearing movement along the front axle when motion and causes contraction of the front bearing hole then to be possible to eliminate the gap between the main axle and the bearing.
The topic main content of topic is hob-cutter frame design as well as the spindle assembly design:8mm maximum machining modulus of the basic parameters,hobbing tool holder to design,develop the overall program,structural design,the main parts of the design calculation and strength check.Make the design of the turret and the table can be used for gear cutting,finally with CAD software to generate drawings.
Key words :gear hobbing machine,cutter frame, gear
