max-height: 320px;" alt="衢州大型齒輪,齒輪" src="http://tyunfile.71360.com/UploadFile/BY13506684752/637181688505605468/2587286.jpg"></div><p> 二、齒輪毛坯的加工 </p> <p> 因為齒面加工和檢測所用的基準(zhǔn)必須在此階段加工出來;無論從提高生產(chǎn)率，還是從保證齒輪的加工質(zhì)量，都必須重視齒輪毛坯的加工。在齒輪的技術(shù)要求中，應(yīng)注意齒頂圓的尺寸精度要求，因為齒厚的檢測是以齒頂圓為測量基準(zhǔn)的，齒頂圓精度太低，必然使所測量出的齒厚值無法正確反映齒側(cè)間隙的大小。 </p> <p> 齒輪常常和減速機安裝使用，齒輪減速機在長時間使用過程中由于摩擦，阻力等多種原因，齒輪精度在不知不覺中會發(fā)生改變，那么要怎么調(diào)整精度呢? </p> <p> 1、調(diào)整間隙法：齒輪減速機在運動過程中會產(chǎn)生摩擦，并引起相關(guān)零件之間的尺寸、形狀和表面質(zhì)量的變化，產(chǎn)生磨損，增大相關(guān)零件之間的配合間隙，此時我們需對其進行調(diào)整，使其在合理范圍內(nèi)，以保證零件之間相對運動的準(zhǔn)確性。 </p><p> 一、定位基準(zhǔn)的選擇 </p> <p> 由于齒輪的結(jié)構(gòu)形狀不同，齒輪定位基準(zhǔn)的選擇也常常不同。帶軸齒輪主要采用前列定位，孔徑大時則采用錐堵。前列定位的精度高，且能做到基準(zhǔn)統(tǒng)一。帶孔齒輪在加工齒面時常采用以下兩種定位、夾緊方式。 </p> <p> (1)以內(nèi)孔和端面定位即以工件內(nèi)孔和端面聯(lián)合定位，確定齒輪中心和軸向位置，并采用面向定位端面的夾緊方式。這種方式可使定位基準(zhǔn)、設(shè)計基準(zhǔn)、裝配基準(zhǔn)和測量基準(zhǔn)重合，定位精度高，適于批量生產(chǎn)。 </p> <p> (2)以外圓和端面定位工件和夾具心軸的配合間隙較大，用千分表校正外圓以決定中心的位置，并以端面定位;從另一端面施以夾緊。這種方式因每個工件都要校正，故生產(chǎn)效率低; </p> <p> <br /> 齒輪砂輪修整量要調(diào)整好，修整牙數(shù)不能過多，多修砂輪讓砂輪氣孔不會堵塞，一直保持鋒利。</p><div style="width:100%;text-align:

齒輪箱是通過大小齒輪的嚙合來實現(xiàn)變su效果的一種變速裝置，在工業(yè)機械的變速方面有很多的應(yīng)用。齒輪箱中的低速軸上安裝有大齒輪，高速軸上安裝有小齒輪，通過齒輪間的嚙合和傳動作用，就可以完成加速或減速的過程。齒輪箱的特點如下： </p> <p> 1、齒輪箱的產(chǎn)品選擇面廣：齒輪箱通常是采用通用的設(shè)計方案，但是在特殊情況下齒輪箱的設(shè)計方案可以根據(jù)使用者的需求而進行變化，變型為行業(yè)**的齒輪箱。齒輪箱的設(shè)計方案中，平行軸、直立軸、通用箱體和各種零部件都能按照使用者要求更改； </p> <p> 2、齒輪箱的運行穩(wěn)定：齒輪箱的運行穩(wěn)定可靠，傳動功率較高。齒輪箱的外部箱體結(jié)構(gòu)可以使用吸音材質(zhì)制造，降低齒輪箱工作過程中產(chǎn)生的噪音。齒輪箱本身具備的箱體結(jié)構(gòu)配合大風(fēng)扇能有效降低齒輪箱的工作溫度。在使用齒輪箱的過程中要及時的主要齒輪箱的清洗問題。齒輪箱清洗機利用齒輪箱原有的給排油系統(tǒng)以及過濾后的潤滑油對齒輪箱進行清洗，不改變齒輪箱任何硬件設(shè)施、不添加任何清洗劑，保證了齒輪箱安全運營，延長了齒輪箱的使用壽命。齒輪廠往往設(shè)一個工段或一個車間來承擔(dān)這項工作。衢州大型齒輪</p><p style="text-indent:25px">可以對齒輪進行滲碳淬火、氮化、調(diào)質(zhì)，對箱體進行回火。衢州大型齒輪</p><p> 漸開線齒輪加工方法有2大類，一個是仿形法，用成型銑刀銑出齒輪的齒槽，是“模仿形狀”的。另一個是范成法（展成法）。 </p> <p> (1)滾齒機滾齒：可以加工8模數(shù)以下的斜齒； </p> <p> (2)銑床銑齒：可以加工直齒條； </p> <p> (3)插床插齒：可以加工內(nèi)齒； </p> <p> (4)冷打機打齒：可以無屑加工； </p> <p> (5)刨齒機刨齒：可以加工16模數(shù)大齒輪； </p> <p> (6)精密鑄齒：可以大批量加工廉價小齒輪； </p> <p> (7)磨齒機磨齒：可以加工精密母機上的齒輪； </p> <p> (8)壓鑄機鑄齒：多數(shù)加工有色金屬齒輪； </p> <p>
