I摘要隨著現(xiàn)代車輛載質(zhì)量的不斷提高，重型車輛的傳動(dòng)比在不斷增大。為了適應(yīng)這一要求，帶有輪邊減速器的雙級(jí)主減速器得到了廣泛應(yīng)用。本文設(shè)計(jì)的輪邊減速器為行星齒輪式輪邊減速器。由于其載重量大，對(duì)結(jié)構(gòu)強(qiáng)度要求較高，選用2K-H型行星齒輪傳動(dòng)機(jī)構(gòu)。根據(jù)車輛的總體設(shè)計(jì)要求，確定輪邊減速器的傳動(dòng)比，參考同類型產(chǎn)品，確定各個(gè)齒輪的齒數(shù)，選擇合適的材料及加工精度。對(duì)各種約束條件進(jìn)行驗(yàn)證，然后對(duì)各個(gè)零件進(jìn)行強(qiáng)度校核。結(jié)合輪邊減速器的設(shè)計(jì)參數(shù)對(duì)該齒輪副進(jìn)行效率檢驗(yàn)。本文利用三維實(shí)體建模技術(shù)對(duì)輪邊減速器進(jìn)行了虛擬制造和虛擬裝配，并進(jìn)行了運(yùn)動(dòng)仿真。通過實(shí)體建模和裝配，對(duì)零件設(shè)計(jì)進(jìn)行干涉檢查。運(yùn)用仿真技術(shù)，對(duì)輪邊減速器的運(yùn)動(dòng)干涉和運(yùn)動(dòng)正確性進(jìn)行檢查。關(guān)鍵詞：輪邊減速器；強(qiáng)度校核；實(shí)體建模。IIAbstractInthisarticle,thedesigningofthewheel-sideplanetaryreducerofSX4180isintroduced.Accordingtothelargeloads,the2K-Hplanetaryreducerischose.First,inaccordancewiththeexperience,thenumberofgearsteethisdesigned.Second,thematerialandtheprecisionwerechose.Then,accordingtothecontactfatiguestrength,themodulusofthegearpearscanbegot.Afterthat,thebendingfatiguestrengthshouldbechecked.Afterdesigningtheparameters,thesizeofmodulescanbegotandtheefficiencycanbechecked.Asthelastlinkofthesystem,thewheelsideplanetarydohardwork.Inthisarticle,anefficientworkwillbedonewiththecomputertechnology.KeyWords:Wheel-sideplanetaryreducer；strengthcheck；Solidmodeling.目錄摘要.IABSTRACT.II目錄.I引言.11緒論.21.1輪邊減速器研究背景.21.2輪邊減速器研究意義.31.3輪邊減速器文獻(xiàn)綜述.41.4研究方向.92輪邊減速器設(shè)計(jì).102.1車型數(shù)據(jù).102.2輪邊減速器設(shè)計(jì)計(jì)算.112.2.1輪邊減速器的傳動(dòng)方案.112.2.2傳動(dòng)比設(shè)計(jì).142.2.3齒輪材料的選擇.142.2.4齒輪模數(shù)的設(shè)計(jì).152.2.5齒輪幾何參數(shù)的確定及校驗(yàn).172.2.6輪邊減速器的結(jié)構(gòu)設(shè)計(jì).202.2.7齒輪傳動(dòng)效率.262.2.8齒輪強(qiáng)度校核驗(yàn)算.272.2.8行星軸的設(shè)計(jì).332.2.9花鍵的選用及校核.342.2.10潤(rùn)滑方式的選擇.373輪邊減速器實(shí)體建模及運(yùn)動(dòng)分析.393.1實(shí)體建模技術(shù)的發(fā)展和選用.393.2輪邊減速器的實(shí)體建模與裝配.
