1）齒輪基本參數(shù)：模數(shù)Mn，齒數(shù)Z，壓力角a，螺旋角β，齒寬b，齒頂圓d，齒根圓de，漸開線起始圓dfe。齒輪2）齒輪精度要求：精度等級(jí)，單個(gè)齒距偏差fpt，齒距累積總誤差Fp,齒廓總偏差Fa，螺旋線總偏差Fβ，徑向跳動(dòng)Fr，公法線長度及偏差Wkn,跨齒數(shù)K。齒輪精度等級(jí)越高，各項(xiàng)偏差值就越小。 </p> <p> 齒輪磨齒加工一般分為展成磨和成形磨。 </p> <p> 1）展成磨加工：以展成線為軌跡，齒向方向線接觸磨削。 </p> <p> 2）成形磨加工：砂輪修形成齒廓形狀，齒向方向面接觸磨削。 </p><p> 一、齒形誤差齒形誤差是指在齒形工作部門內(nèi)，包容實(shí)際齒形廓線的兩理想齒形(漸開線)廓線間的法向間隔。齒輪滾刀是加工外嚙合直齒和斜齒圓柱漸開線齒輪**常用的一種工具。這種滾刀側(cè)后刀面的軸向截形是直線，如果用它代替漸開線滾刀切齒時(shí)，則切出的齒輪齒形不是漸開線，因而在理論上造成了一定的齒形誤差，稱為齒輪滾刀的造形誤差。另外，在實(shí)際加工過程中不可能獲得完全準(zhǔn)確的漸開線齒形，老是存在各種誤差，從而影響傳動(dòng)的平穩(wěn)性。齒輪的基圓是決定漸開線齒形的惟一參數(shù)，假如在滾齒加工時(shí)基圓產(chǎn)生誤差，齒形勢必也會(huì)有誤差。齒輪齒面硬度高會(huì)出現(xiàn)輪磨削裂紋。</p><div

在實(shí)際應(yīng)用中，對于尚未制定出判定標(biāo)準(zhǔn)的齒輪，可以充分利用現(xiàn)場測量的數(shù)據(jù)進(jìn)行統(tǒng)計(jì)平均，制定適當(dāng)?shù)南鄬ε卸?biāo)準(zhǔn)，采用這種標(biāo)準(zhǔn)進(jìn)行判定稱為相對值判定法。 </p> <p> 相對判定標(biāo)準(zhǔn)要求將在齒輪箱同一部位測點(diǎn)在不同時(shí)刻測得的振幅與正常狀態(tài)下的振幅相比較，當(dāng)測量值和正常值相比達(dá)到一定程度時(shí)，判定為某一狀態(tài)。比如，相對值判定標(biāo)準(zhǔn)規(guī)定實(shí)際值達(dá)到正常值的1點(diǎn)6~2倍時(shí)要引起注意，達(dá)到2點(diǎn)56~4倍時(shí)則表示危險(xiǎn)等。至于具體使用時(shí)是按照1點(diǎn)6倍進(jìn)行分級(jí)還是按照2倍進(jìn)行分級(jí)，則視齒輪箱的使用要求而定，比較粗糙的設(shè)備（例如礦山機(jī)械）一般使用倍數(shù)較高的分級(jí)。 </p> <p> 實(shí)際中，為了達(dá)到比較好效果，可以同時(shí)采用上述兩種方法，以便對比比較，評價(jià)。齒輪在傳動(dòng)中的應(yīng)用很早就出現(xiàn)了。杭州印刷齒輪</p><p style="text-indent:25px">齒輪的使用時(shí)間是多久呢？杭州印刷齒輪</p><p> 齒輪及其齒輪產(chǎn)品是機(jī)械裝備的重要基礎(chǔ)件，絕大部分機(jī)械成套設(shè)備的主要傳動(dòng)部件都是齒輪傳動(dòng)。隨著國民經(jīng)濟(jì)的高速發(fā)展，全行業(yè)年銷售總額已突破千億元，形成了企業(yè)多元并存、共同發(fā)展的行業(yè)格局。其中，**企業(yè)、骨干企業(yè)已成為推動(dòng)行業(yè)管理水平、產(chǎn)品技術(shù)質(zhì)量水平和自主創(chuàng)新能力提升的重要力量，為把我國從齒輪制造大國建設(shè)成為齒輪制造強(qiáng)國做出了突出貢獻(xiàn)。 </p> <p> 根據(jù)（中國齒輪行業(yè)產(chǎn)銷需求預(yù)測與轉(zhuǎn)型升級(jí)分析報(bào)告）顯示中國齒輪傳動(dòng)行業(yè)在“十一五”期間得到了快速發(fā)展，2005-2010年中國齒輪行業(yè)的工業(yè)總產(chǎn)值逐年增加，且同比增幅均在20%以上。2010年整個(gè)齒輪產(chǎn)業(yè)實(shí)現(xiàn)工業(yè)總產(chǎn)值上百億元，齒輪全行業(yè)市場需求超過上千億元，世界排名第二。從規(guī)模和銷售額等各方面因素來看，齒輪產(chǎn)業(yè)已然成為中國機(jī)械通用零部件基礎(chǔ)件領(lǐng)域的“**”級(jí)行業(yè)。中國已經(jīng)成為名副其實(shí)的世界齒輪制造大國。杭州印刷齒輪</p><p
