style="text-indent:25px">軸承是當(dāng)代機(jī)械設(shè)備中一種重要零部件，它的主要功能是支撐機(jī)械旋轉(zhuǎn)體，降低其運(yùn)動(dòng)過程中的摩擦系數(shù)，并保證其回轉(zhuǎn)精度。按運(yùn)動(dòng)元件摩擦性質(zhì)的不同，軸承可分為滾動(dòng)軸承和滑動(dòng)軸承兩大類。其中滾動(dòng)軸承已經(jīng)標(biāo)準(zhǔn)化、系列化，但與滑動(dòng)軸承相比它的徑向尺寸、振動(dòng)和噪聲較大，價(jià)格也較高。說說其中滾珠軸承制作的過程，先將軸承內(nèi)外圈推入設(shè)備進(jìn)行打磨；用水對(duì)其進(jìn)行冷卻，防止過熱產(chǎn)生形變；內(nèi)外圈打磨后，對(duì)其進(jìn)行涂油；將鋼材切割成圓柱體后進(jìn)行按壓成形；再進(jìn)行打磨、剖光；將內(nèi)圈安置在外圈上；鋼珠通過管道輸安裝于內(nèi)外環(huán)之間即可。江蘇全自動(dòng)軸承清洗機(jī)軸承套圈集中工序只用了一道工序就可完成一個(gè)或幾個(gè)套圈的車削加工。</p><div

style="text-indent:25px">立方氮化硼磨料簡(jiǎn)稱CBN磨料，由其制造的砂輪稱為CBN砂輪，其主要具有下列特征： ⑴ 硬度高，導(dǎo)熱率高，熱穩(wěn)定性好，可承受1300～1500℃高溫。 ⑵ 耐用性高，磨耗小，磨削比可達(dá)4000～10000（磨削比是指磨削過程去除工件材料量與砂輪磨損量的比值）而普通剛玉砂輪*為50～80。 ⑶ 磨削力小，磨削熱小，加工工件應(yīng)力小，表層應(yīng)力薄或沒有。⑷ 輔助時(shí)間（修整砂輪、更換砂輪）減少。對(duì)我國(guó)軸承行業(yè)來說，利用CBN進(jìn)行套圈磨削加工是種新的加工技術(shù)，應(yīng)用前景非常廣闊。由于CBN砂輪具有良好的加工特點(diǎn)，利用CBN砂輪進(jìn)行軸承套圈磨削國(guó)外早已進(jìn)行了研制并應(yīng)用于生產(chǎn)中。</p><p style="text-indent:25px">軸承的加工精度，是由機(jī)器設(shè)備加工精度決定還是由工藝控制的？比如機(jī)器的加工精度一般更多加工到P6精度，如果想加工P4精度的，可以用控制工藝的方法達(dá)到嗎？其實(shí)產(chǎn)品零件的加工精度是由工作母機(jī)的精度來決定的。如果機(jī)器的性能不足夠好，加工出來的產(chǎn)品也一定達(dá)不到比自身性能好的產(chǎn)品，尤其是批量加工出來的產(chǎn)品。從低精度的產(chǎn)品中挑選高精度的產(chǎn)品是比較費(fèi)勁的事。如果您的設(shè)備只能做到6級(jí)精度的產(chǎn)品，要做出4級(jí)精度的產(chǎn)品是比較難的，廢品率會(huì)比較高的，可能會(huì)得不償失。70年代則主要是以應(yīng)用60m/s高速磨削、控制力磨削技術(shù)及控制力磨床大量采用。</p><div

style="text-indent:25px">如何采用新工藝，新技術(shù)，以高精度、高效率、低成本地完成磨削過程，便是磨削加工的主要任務(wù)。安徽加工軸承座</p><p style="text-indent:25px">主軸錐孔相對(duì)于支承軸頸的位置精度是靠采用支承軸頸A、T作為定位基準(zhǔn)，而讓被加工主軸裝夾在磨床工作臺(tái)上加工來保證。以支承軸頸作為定位基準(zhǔn)加工內(nèi)錐面，符合基準(zhǔn)重合原則。在精磨前端錐孔之前，應(yīng)使作為定位基準(zhǔn)的支承軸頸A、T達(dá)到一定的精度。主軸錐孔的磨削一般采用**夾具，夾具由底座、支架、及浮動(dòng)夾頭三部分組成，兩個(gè)支架固定在底座上，作為工件定位基準(zhǔn)面的兩段軸頸放在支架的兩個(gè)V形塊上，V形塊鑲有硬質(zhì)合金，以提高耐磨性，并減少對(duì)工件軸頸的劃痕，工件的中心高應(yīng)正好等于磨頭砂輪軸的中心高，否則將會(huì)使錐孔母線呈雙曲線，影響內(nèi)錐孔的接觸精度。后端的浮動(dòng)卡頭用錐柄裝在磨床主軸的錐孔內(nèi)，工件尾端插于彈性套內(nèi)，用彈簧將浮動(dòng)卡頭外殼連同工件向左拉，通過鋼球壓向鑲有硬質(zhì)合金的錐柄端面，限制工件的軸向竄動(dòng)。采用這種聯(lián)接方式，可以保證工件支承軸頸的定位精度不受內(nèi)圓磨床主軸回轉(zhuǎn)誤差的影響，也可減少機(jī)床本身振動(dòng)對(duì)加工質(zhì)量的影響。安徽加工軸承座</p><p
