It introduces the present situation of our country39。s shear machine type, the future direction of development, put forward the shear machine in production problems。 And then the blade of the transmission system of cold cut machine, the article analyzes the design scheme, then to the main parts of shearing mechanism analysis of stress and intensity. On the choice of gear respectively, the choice of the shaft bearing and pulley, and the selection of design calculation, and, in doing so, also checks. The design of gear, I use is on gear tooth surface contact fatigue strength calculation, and use the tooth root bending fatigue strength checks. In checking process, the design of gear check had a deeper understanding, and how to choose the right in shear machine of the gear. And the shear machine of main ponents of lubrication method were discussed, use ATUOCAD software, to the design reliability and economical analysis and evaluation. Keywords: Inclined blade cutting machine 。 ATUOCAD software ；design。 checked.目錄摘要…………………………………………………………………………….Ⅰ遼寧科技大學(xué)本科生畢業(yè)設(shè)計(jì) （論文） 第 IV 頁Abstract………………………………………………………………………..Ⅱ1 緒論 ..............................................................................................................1 剪切機(jī)的種類 ..................................................................................................................1 平行刃剪切機(jī) ....................................................................................................1 斜刃剪切機(jī) ........................................................................................................1 圓盤式剪切機(jī) ....................................................................................................2 沖型剪切機(jī) ........................................................................................................3 聯(lián)合剪切機(jī) ........................................................................................................3 型材棒料剪切機(jī) ................................................................................................3 剪切生產(chǎn)中存在的問題 ...........................................................................................42 傳動(dòng)方案的選擇 ..........................................................................................6 皮帶傳動(dòng)的選擇 ...............................................................................................................6 減速器傳動(dòng)選擇 ...............................................................................................................6 齒輪轉(zhuǎn)動(dòng)選擇 ...................................................................................................................7 ...................................................................................8 設(shè)計(jì)的基本要求 ...............................................................................................................8 剪切機(jī)構(gòu) ...........................................................................................................................8 主要參數(shù)的確定 ...............................................................................................................9 刀片的行程.................................................................................................................9 刀片尺寸.................................................................................................................10 理論空行程次數(shù).....................................................................................................10 剪切力的計(jì)算 .................................................................................................................10 單位剪切阻力曲線.................................................................................................10 最大剪切力.............................................................................................................11 電機(jī)容量的選擇 .............................................................................................................13 = f(α)曲線繪制 ......................................................................................................13=f(α)曲線的繪制 .....................................................................................................13 偏心軸上的靜力矩計(jì)算...........................................................................................13遼寧科技大學(xué)本科生畢業(yè)設(shè)計(jì) （論文） 第 V 頁4 主要零件的強(qiáng)度計(jì)算 ......................................................................................19 曲軸的設(shè)計(jì) .....................................................................................................................19 曲軸的計(jì)算 .....................................................................................................................20 齒輪的計(jì)算與校核 .........................................................................................................21 選定齒輪類型，精度等級(jí)，材料及齒數(shù)...............................................................21 設(shè)計(jì)計(jì)算齒面接觸接觸強(qiáng)度 ......................................................................................22........................................................................................................22.................................................................................................................22 按彎曲疲勞強(qiáng)度進(jìn)行較核設(shè)計(jì)...........................
