在實際應(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在不同時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，判定為某一狀態(tài)。比如，相對值判定標(biāo)準(zhǔn)規(guī)定實際值達(dá)到正常值的1點6~2倍時要引起注意，達(dá)到2點56~4倍時則表示危險等。至于具體使用時是按照1點6倍進(jìn)行分級還是按照2倍進(jìn)行分級，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。 </p> <p> 實際中，為了達(dá)到比較好效果，可以同時采用上述兩種方法，以便對比比較，評價。寧波大型齒輪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。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="臺州減速齒輪,齒輪"

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 /> </p><p> 仔細(xì)觀察就會發(fā)現(xiàn)，這種齒輪的齒并不是梯形，而是兩邊呈現(xiàn)出一定的弧度。它的好處是齒間嚙合可以始終保持相同的速度，減少齒間的碰撞，進(jìn)而提高齒輪的使用壽命。 </p> <p> 齒輪除了實用，本身還是一件精致的工藝品。當(dāng)許多不同種類的齒輪結(jié)合成一個精密復(fù)雜的系統(tǒng)時，向人們傳達(dá)的是理性與感性并存的美感。 </p> <p> 齒輪的尺寸用齒頂圓直徑、齒根圓直徑、齒厚及齒寬等，齒輪與齒輪相互嚙合的點稱為嚙合點，這個點的運動軌跡稱為嚙合圓。其次，在分度圓的圓周上，一個輪齒兩側(cè)齒廓間的弧長稱為該輪齒的齒厚，在齒輪的一個齒槽內(nèi)其兩側(cè)齒線的弧長稱為該輪齒的齒槽寬。還有，齒厚與齒槽寬之間的差距，也就是說嚙合傳動的輪齒反轉(zhuǎn)時的游隙稱為齒間隙，為了使齒輪平穩(wěn)嚙合必須要有適度的齒間隙。齒輪在工作中有什么樣的用處？</p><div

傳動精度齒距誤差是衡量齒輪精度的**主要指標(biāo)（齒距誤差和背隙有一定換算關(guān)系，商家更喜歡標(biāo)背隙而不是齒距誤差，因為背隙的數(shù)據(jù)更好看，就像寬帶運營商喜歡標(biāo) Mbps 而不是 MB），良好設(shè)計的齒輪，齒距誤差為 0 的情況下，例如 1 模 30 齒的齒輪副，很容易做到扭矩誤差 < 0點5%（角度誤差 < 0點05度）。但如果有 5 微米（對的，不是 0點05 mm，是 0點005 mm）的齒距誤差，扭矩誤差就會超過 3%，然而 5 微米已經(jīng)屬于國標(biāo) 5 級精度了，機(jī)械手用的精密減速機(jī)通常也只有 5 級精度。齒輪精度等級劃分中，相鄰兩個精度等級一般只差 2～5
