可任意分度的插齒機(jī)齒輪加工回轉(zhuǎn)工作臺(tái)的設(shè)計(jì).docVIP

摘要插齒機(jī)作為齒輪加工機(jī)床的一種，已逐步體現(xiàn)出其加工的優(yōu)越性，在滾齒機(jī)、銑齒機(jī)上無法加工的一些齒輪，如雙聯(lián)齒輪和內(nèi)齒輪，在插齒機(jī)上可加工制造出來。在本課題的設(shè)計(jì)中，采用步進(jìn)電機(jī)控制回轉(zhuǎn)工作臺(tái)的轉(zhuǎn)角。在單片機(jī)的控制下，步進(jìn)電機(jī)每秒鐘發(fā)出的脈沖數(shù)決定了工作臺(tái)的轉(zhuǎn)位角度，使該插齒機(jī)成為真正意義上的可任意分度加工，進(jìn)而可實(shí)現(xiàn)加工任意齒數(shù)的齒輪。本課題所設(shè)計(jì)的回轉(zhuǎn)工作臺(tái)是用單片機(jī)作為控制系統(tǒng)來控制步進(jìn)電機(jī)的轉(zhuǎn)速，動(dòng)力由步進(jìn)電機(jī)發(fā)出，通過齒輪傳動(dòng)和蝸輪蝸桿傳動(dòng)，將動(dòng)力傳遞到蝸輪上，蝸輪的轉(zhuǎn)動(dòng)再帶動(dòng)主軸轉(zhuǎn)動(dòng)，從而實(shí)現(xiàn)與主軸夾緊的工件的轉(zhuǎn)動(dòng)。所設(shè)計(jì)的回轉(zhuǎn)工作臺(tái)實(shí)用、簡單、可靠、效率高。關(guān)鍵詞步進(jìn)電機(jī)；回轉(zhuǎn)工作臺(tái)；單片機(jī)；任意分度AbstractAsonekindofthegearfinishinglathes,thegearshaperhasmanifestedthesuperiorityinprocessinggradually,onthegear-hobbingmachine,thegearcuttercanntbetrue,forexampl-e,thetwingearandtheannulargear,buttheycanbeprocessedonthegearshaper.Inthisdesign,Iuseastep-by-steptheelectricalmachinerytocontrolthecornerofrotarytable.Underthecontrolofmonolithicintegratedcircuit,thenumberofpulseofthestep-by-stepelectricalmachineryeachsecondcanbesentouttodecidetherotarytablesindexingangle,makingthegearshapertobecometherandomindexingprocessinginthetruesense.Andthen,thegearprocessingwhichismentionedwillfullymightberealized.Therotarytabledesignedinthistopiciscontroledbythemonolithicintegratedcircuittocontroltherotationalspeedofstep-by-stepelectricalmachinery,thestep-by-stepelectricalmachinerysendoutthepowerfirstly,throughthegeardriveandthewormgearwormdrive,thenthepoweristransmistedtowormgear,andwormgear-rotatingmakesthemainaxlerotatethesametime,andthen,itcomestoberealizedthattheworkpiececlampedwithmainaxlecometorotate.Inmyopinion，thisdesignoftherotarytableispractical,simple,reliable,andtheefficiencyishigh.K目錄1緒論.11.1本課題的背景及應(yīng)解決的主要問題.11.2本課題的研究目的和現(xiàn)實(shí)意義.11.3插齒概述.21.4插齒機(jī)類型與適用范圍.21.4.1插齒機(jī)類型.21.4.2各種插齒機(jī)的適用范圍.31.5插齒機(jī)的工作原理及其參數(shù).31.5.1插齒機(jī)的外觀圖.31.5.2插齒機(jī)的工作原理.41.5.3插齒機(jī)的參數(shù).52設(shè)計(jì)方案選擇.62.1分度工作臺(tái).62.2數(shù)控回轉(zhuǎn)工作臺(tái).62.2.1開環(huán)數(shù)控轉(zhuǎn)臺(tái).62.2.2閉環(huán)數(shù)控回轉(zhuǎn)工作臺(tái).73工作臺(tái)設(shè)計(jì).83.1步進(jìn)電機(jī)的選擇與控制.83.1.1步進(jìn)電動(dòng)機(jī)的特點(diǎn)與種類.83.1.2步進(jìn)電動(dòng)機(jī)的選擇.93.1.3步進(jìn)電動(dòng)機(jī)的控制.93.2蝸輪蝸桿設(shè)計(jì)計(jì)算.143.2.1蝸桿傳動(dòng)輸入?yún)?shù).143.2.2接觸疲勞強(qiáng)度計(jì)算.153.2.3確定蝸輪蝸桿的主要尺寸.163.2.4確定蝸輪蝸桿的傳動(dòng)效率.163.2.5選擇蝸輪蝸桿的精度等級(jí).173.2.6蝸輪蝸桿傳動(dòng)的熱平衡計(jì)算.173.3齒輪設(shè)計(jì)計(jì)算.183.3.1齒輪設(shè)計(jì)輸入?yún)?shù).183.3.2齒輪的材料及熱處理.183.3.3齒輪的基本參數(shù).183.3.4齒面接觸疲勞強(qiáng)度校核.203.3.5齒根彎曲強(qiáng)度校核.213.4軸承設(shè)計(jì)計(jì)算.213.4.1軸承方案選擇.213.4.
