齒輪軸一般是小齒輪（齒數(shù)少的齒輪）。 </p> <p> 齒輪軸一般是在高速級(jí)（也就是低扭矩級(jí)）。 </p> <p> 齒輪軸一般很少作為變速的滑移齒輪，一般都是固定運(yùn)行的齒輪，一是因?yàn)樘幵诟咚偌?jí)，青海本地齒輪制造，青海本地齒輪制造，其高速度是不適進(jìn)行滑移變速的。 </p> <p> 齒輪軸是軸和齒輪合成一個(gè)整體的，但是，在設(shè)計(jì)時(shí)，還是要盡量縮短軸的長度，太長了一是不利于上滾齒機(jī)加工，二是軸的支撐太長導(dǎo)致軸要加粗而增加機(jī)械強(qiáng)度（如剛性、撓度、抗彎等）。 </p> <p> 齒輪軸的加工工藝分析有定位基準(zhǔn)的選擇：齒輪軸主要表面的加工順序，在很大程度上取決于定位基準(zhǔn)的選擇。軸類零件本身的結(jié)構(gòu)特征和主軸各主要表面的位置精度要求都決定了以軸線為定位基準(zhǔn)是**理想的。這樣既保證基準(zhǔn)統(tǒng)一，青海本地齒輪制造，又使定位基準(zhǔn)與設(shè)計(jì)基準(zhǔn)重合。一般多以外圓為粗基準(zhǔn)，以軸兩端的項(xiàng)尖孔為精基準(zhǔn)。

粗加工或不能用兩端前列孔（如加工主軸錐孔）定位時(shí)，為提高工件加工時(shí)工藝系統(tǒng)的剛度，可只用外圓表面定位或用外圓表面和一端中心孔作為定位基準(zhǔn)。在加工過程中，應(yīng)交替使用軸的外圓和一端中心孔作為定位基準(zhǔn)，以滿足相互位置精度要求。 </p> <p> 如果軸是帶通孔的零件，通孔鉆出后將使原來的前列孔消失。為了仍能用前列孔定位，一般均采用帶有前列孔的錐堵或錐套心軸。當(dāng)軸孔的錐度較大（如銑床主軸）時(shí)，可用錐套心軸；當(dāng)主軸錐孔的錐度較小（如CA6140型機(jī)床主軸）時(shí)，可采用錐堵。必須注意，使用的錐套心軸和錐堵應(yīng)具備較高的精度并盡量減少其安裝次數(shù)。錐堵和錐套心軸上的中心孔既是其本身制造的定位基準(zhǔn)，又是主軸外圓的精加工基準(zhǔn)，因此必須保證錐堵或錐套心軸上的錐面與中心孔有較高的同軸度。若為中小批生產(chǎn)，工件在錐堵上安裝后一般中途不更換。若外圓和錐孔需反復(fù)多次互為基準(zhǔn)進(jìn)行加工，則在重裝錐堵或軸套心軸時(shí)必須按外圓找正或重新修磨中心孔。

罩的入孔門沒有安裝門蓋，造成灰塵進(jìn)入保護(hù)罩內(nèi)的齒輪中。特別是球磨機(jī)空心軸與保護(hù)罩的動(dòng)靜結(jié)合處，都沒有安裝密封，使大牙輪內(nèi)的進(jìn)灰加劇。該鍋爐的預(yù)熱器為3分倉式，一路是送風(fēng)機(jī)的二次風(fēng)，另一路是一次風(fēng)機(jī)的熱一次風(fēng)，由于一次風(fēng)壓過高，將預(yù)熱器受熱面從煙氣側(cè)攜帶積存的灰(灰中含有高硬度的漂珠Al2O3)吹下后帶走，而熱風(fēng)系統(tǒng)的許多管道焊口不合格，造成嚴(yán)重泄漏。泄出的灰塵進(jìn)入齒輪護(hù)罩內(nèi)加劇了齒輪的磨損。 </p> <p> 每臺(tái)球磨機(jī)的大牙輪配有一臺(tái)美國LIN-COLN公司生產(chǎn)的自動(dòng)噴油裝置，沿大牙輪齒寬安裝有4個(gè)噴嘴，試運(yùn)時(shí)設(shè)定每隔2 min噴油一次，噴油時(shí)間2 s，每個(gè)噴嘴一次噴油約1.3 g。因?yàn)樵撉蚰C(jī)大牙輪的齒為斜齒，齒面上不易存油，所以噴油時(shí)間較頻繁。投產(chǎn)后改為每間隔15 min噴油一次，后來發(fā)現(xiàn)大小牙輪齒面磨損、起皮、點(diǎn)蝕等現(xiàn)象，又將噴油間隔時(shí)間改為8min。5號(hào)爐投產(chǎn)初期還幾次發(fā)現(xiàn)噴油裝置上蓋被人為提起后用鐵絲掛在球磨機(jī)保護(hù)罩上，而下部的油桶則不知去向。雖然噴油裝置仍在工作，但是噴進(jìn)去的不是油而是空氣，這也加劇了齒輪的點(diǎn)蝕。
