</p> <p> <br /> </p> <p> 一、根據(jù)軸承承受載荷的大小、方向和性質(zhì) </p> <p> 1.載荷小而平穩(wěn)時，宜用滾子軸承。 </p> <p> 2.當軸承只承受徑向載荷時，可選用向心球軸承或向心短圓柱滾子軸承；當軸承只承受軸向載荷時，可選用推力球軸承。 </p> <p> 3.當軸承同時受軸向載荷和徑向載荷作用時，應(yīng)根據(jù)軸向載荷A和徑向載荷R的相對值來考慮。 </p> <p> ａ當A比R小很多時，可選用向心球軸承。 </p> <p> ｂ當A<R時，選用向心推力球軸承或圓錐滾子軸承。 </p> <p> ｃ當A>R時，可選用大接觸角的向心推力球軸承和大錐角的圓錐滾子軸承。 </p> <p> ｄ當A比R大很多時，可將推力軸承和向心軸承組合使用，分別承受軸向和徑向載荷。江蘇性能價格比高的ABL軸承部件加工過程中要注意三大事項，分別為：固定進刀退刀模式、養(yǎng)成規(guī)范的調(diào)試動作和換刀點設(shè)定模塊化。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="浙江ABL辦公設(shè)備軸承,ABL" src="https://tyunfile.71360.com/WaterMark/UploadFile/shhcjmcd/637465784268665459/5405996.png"></div><p> 一、軸承的滾動聲 </p> <p> 采用測聲器對運轉(zhuǎn)中的軸承的滾動聲的大小及音質(zhì)進行檢查，軸承即使有輕微的剝離等損傷，也會發(fā)出異常音和不規(guī)則音，用測聲器能夠分辨。 </p> <p> <br /> </p> <p> 二、軸承的振動 </p> <p> <br /> </p> <p> 軸承振動對軸承的損傷很敏感，例如剝落、壓痕、銹蝕、裂紋、磨損等都會在軸承振動測量中反映出來，所以，通過采用特殊的軸承振動測量器（頻率分析器等）可測量出振動的大小，通過頻率推斷出異常的具體情況。測得的數(shù)值因軸承的使用條件或傳感器安裝位置等而不同，因此需要事先對每臺機器的測量值進行分析比較后確定判斷標準。 </p> <p> 三、軸承的溫度 </p> <p> 通常軸承的溫度隨著運轉(zhuǎn)開始慢慢上升，1-2小時后達到穩(wěn)定狀態(tài)。軸承的正常溫度因機器的熱容量、散熱量、轉(zhuǎn)速及負載而不同。如果潤滑、安裝部合適，則軸承溫都會急驟上升，會出現(xiàn)異常高溫，這時必須停止運轉(zhuǎn)，采取必要的防范措施。使用熱感器可以隨時監(jiān)測軸承的工作溫度，并實現(xiàn)溫度超過規(guī)定值時自動報警或停止，防止燃軸事故發(fā)生。 </p> <p> 現(xiàn)代化機械設(shè)備幾乎都是需要大量資金的裝備，設(shè)備的購買、維修和使用費用十分昂貴，迫切需要設(shè)備管理的經(jīng)濟效益必經(jīng)通過對設(shè)備日常的維護和保養(yǎng)，來減少設(shè)備的有形磨損，減少設(shè)備壽命周期內(nèi)的維修費用和其他非正常開支。 </p><p> 從轉(zhuǎn)速對軸承的要求，可確定以下幾點： </p> <p> <br /> </p> <p> １）球軸承與滾子軸承相比，有較高的極限轉(zhuǎn)速，故在高速時應(yīng)優(yōu)先選用球軸承； </p> <p> <br /> </p> <p> ２）在內(nèi)徑相同的條件下，外徑越小，滾動體就越輕小，運轉(zhuǎn)時滾動體加在外圈滾道上的離心慣性力就越小，因而就更適合用在更高的轉(zhuǎn)速下工作。故在高速時，宜選用超輕、特輕及輕系列的軸承。重及特重系列的軸承，只用于低速重載的場合。如用一個輕系列軸承而承載能力達不到要求時，可考慮采用寬系列的軸承，或者把兩個輕系列的軸承并裝在一起使用。 </p> <p> <br /> </p> <p> ３）保持架的材料與結(jié)構(gòu)對軸承轉(zhuǎn)速影響極大。實體保持架比沖壓保持架允許更高一些的轉(zhuǎn)速。 </p> <p> <br /> </p> <p> ４）推力軸承的極限轉(zhuǎn)速均很低。當工作轉(zhuǎn)速高時，若軸向載荷不十分大，可采用角接觸球軸承承受純軸向力。 </p> <p> <br /> </p> <p> ５）若工作轉(zhuǎn)速略超過樣本中規(guī)定的極限轉(zhuǎn)速，可用提高軸承的公差等級，或適當?shù)丶哟筝S承的徑向間隙，選用循環(huán)潤滑或油霧潤滑，加強對循環(huán)油的冷卻等措施來改善軸承的告訴性能。若工作轉(zhuǎn)速超過極限轉(zhuǎn)速較多，應(yīng)選用特制的高速滾動軸承。滾動軸承是精密的機械零件，其精度是以微米為計算單位。</p><div

用高溫經(jīng)常表示軸承已處于異常情況。高溫也有害于軸承潤滑劑。有時軸承過熱可歸類于軸承的潤滑劑。若軸承在超過125℃的溫度長期連轉(zhuǎn)會降低軸承壽命。引起高溫軸承的原因包括：潤滑不足或過分潤滑、潤滑劑內(nèi)含有雜質(zhì)、負載過大、軸承損壞、間隙不足及油封產(chǎn)生的高摩擦等等。 </p> <p> 因此，連續(xù)性的監(jiān)測軸承溫度是有必要的，無論是測量軸承本身或其它重要的零件。如果是在運轉(zhuǎn)條件不變的情況下，任何的溫度改變可表示已發(fā)生故障。 </p> <p> 軸承溫度的定期量測可藉助于溫度計，例如SKF數(shù)字型溫度計，可精確地測軸承溫度并依攝氏溫度或華氏溫度定單位顯示。 </p> <p> 重要性的軸承，意味著當其損壞時，會造成設(shè)備的停機，因此這類軸承比較好應(yīng)加裝溫度探測器。 </p> <p> <br /> NSK軸承動力特性的分析涉及固體接觸的彈性變形與彈性流體動力潤滑分析及其相互影響修正。上海進口ABL</p><p
