采用測(cè)聲器對(duì)運(yùn)轉(zhuǎn)中的軸承的滾動(dòng)聲的大小及音質(zhì)進(jìn)行檢查，軸承即使有輕微的剝離等損傷，也會(huì)發(fā)出異常音和不規(guī)則音，用測(cè)聲器能夠分辨。 </p> <p> <br /> </p> <p> 二、軸承的振動(dòng) </p> <p> <br /> </p> <p> 軸承振動(dòng)對(duì)軸承的損傷很敏感，例如剝落、壓痕、銹蝕、裂紋、磨損等都會(huì)在軸承振動(dòng)測(cè)量中反映出來(lái)，所以，通過(guò)采用特殊的軸承振動(dòng)測(cè)量器（頻率分析器等）可測(cè)量出振動(dòng)的大小，通過(guò)頻率推斷出異常的具體情況。測(cè)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(duì)每臺(tái)機(jī)器的測(cè)量值進(jìn)行分析比較后確定判斷標(biāo)準(zhǔn)。 </p> <p> 三、軸承的溫度 </p> <p> 通常軸承的溫度隨著運(yùn)轉(zhuǎn)開始慢慢上升，1-2小時(shí)后達(dá)到穩(wěn)定狀態(tài)。軸承的正常溫度因機(jī)器的熱容量、散熱量、轉(zhuǎn)速及負(fù)載而不同。如果潤(rùn)滑、安裝部合適，則軸承溫都會(huì)急驟上升，會(huì)出現(xiàn)異常高溫，這時(shí)必須停止運(yùn)轉(zhuǎn)，采取必要的防范措施。使用熱感器可以隨時(shí)監(jiān)測(cè)軸承的工作溫度，并實(shí)現(xiàn)溫度超過(guò)規(guī)定值時(shí)自動(dòng)報(bào)警或停止，防止燃軸事故發(fā)生。

在利用振動(dòng)對(duì)滾動(dòng)軸承進(jìn)行簡(jiǎn)易診斷的過(guò)程中，通常是要測(cè)得的振值（峰值、有效值等）與預(yù)先給定的某種判定標(biāo)準(zhǔn)進(jìn)行比較，根據(jù)實(shí)測(cè)的振值是否超出了標(biāo)準(zhǔn)給出的界限來(lái)判斷軸承是否出現(xiàn)了故障，以決定是否需要進(jìn)一步進(jìn)行精密診斷。用于滾動(dòng)軸承簡(jiǎn)易診斷的判斷標(biāo)準(zhǔn)可大致分為三種： </p> <p> （1）判定標(biāo)準(zhǔn)：是用于判斷實(shí)測(cè)振值是否超限的量值； </p> <p> （2）相對(duì)判定標(biāo)準(zhǔn)：是對(duì)軸承的同一部位定期進(jìn)行振動(dòng)檢測(cè)，并按時(shí)間先后進(jìn)行比較，以軸承無(wú)故障的情況下的振值為標(biāo)準(zhǔn)，根據(jù)實(shí)測(cè)振值與該基準(zhǔn)振值之比來(lái)進(jìn)行診斷的標(biāo)準(zhǔn)； </p> <p> （3）類比判定標(biāo)準(zhǔn)：是把若干同一型號(hào)的軸承在相同的條件下在同一部位進(jìn)行振動(dòng)檢測(cè)，并將振值相互比較進(jìn)行判斷的標(biāo)準(zhǔn)。 ABL軸承是的高級(jí)工程軸承和合金鋼制造商；提供日本NTN軸承 4T-A4059/A4138 ；</p><div style="width:100%;text-align:

style="text-indent:25px">NTN軸承如何選擇潤(rùn)滑脂：潤(rùn)滑對(duì)軸承的運(yùn)轉(zhuǎn)及壽命有極為重要的影響。這里向您簡(jiǎn)要介紹選擇潤(rùn)滑脂的一般原則。潤(rùn)滑脂由基礎(chǔ)油、增稠劑及添加劑制成，不同種類和同一種類不同牌號(hào)的潤(rùn)滑脂性能相差很大，允許的旋轉(zhuǎn)極限不同，在選擇時(shí)務(wù)必注意。潤(rùn)滑脂的性能主要由基礎(chǔ)油決定。一般低粘度的基礎(chǔ)油適用于低溫、高速；高粘度的適用于高溫、高負(fù)荷。增稠劑也關(guān)系著潤(rùn)滑性能，增稠劑的耐水性決定潤(rùn)滑脂的耐水性。原則上，牌子不同的潤(rùn)滑脂不能混合，而且，即使是同種增稠劑的潤(rùn)滑脂，也會(huì)因添加劑不同相互帶來(lái)壞影響。在潤(rùn)滑軸承時(shí)，油脂涂的越多越好嗎潤(rùn)滑軸承時(shí)，油脂涂的越多越好，這是一個(gè)常見(jiàn)的錯(cuò)誤概念。軸承和軸承室內(nèi)過(guò)多的油脂將造成油脂的過(guò)度攪拌，從而產(chǎn)生極高的溫度。ABL軸承----用于生產(chǎn)供所有領(lǐng)域使用的精密機(jī)械；提供日本NTN軸承
