峭度系數(shù)診斷法。振幅滿足正態(tài)分布規(guī)律的無(wú)故障軸承，其峭度值約為3。隨著故障的出現(xiàn)和發(fā)展，峭度值具有與波峰因數(shù)類似的變化趨勢(shì)。此方法的優(yōu)點(diǎn)在于與軸承的轉(zhuǎn)速、尺寸和載荷無(wú)關(guān)，主要適用于點(diǎn)蝕類故障的診斷。 </p> <p> 波形因數(shù)診斷法波形因數(shù)定義為峰值與均值之比（XP/X）。該值也是用于滾動(dòng)軸承簡(jiǎn)易診斷的有效指標(biāo)之一。 </p> <p> 波峰因數(shù)診斷法波峰因數(shù)定義為峰值與均方根值之比（XP/Xrms）。該值用于滾動(dòng)軸承簡(jiǎn)易診斷的優(yōu)點(diǎn)在于它不受軸承尺寸、轉(zhuǎn)速及載荷的影響，也不受傳感器、放大器等一、二次儀表靈敏度變化的影響。該值適用于點(diǎn)蝕類故障的診斷。通過(guò)對(duì)XP/Xrms值隨時(shí)間變化趨勢(shì)的監(jiān)測(cè)，可以有效地對(duì)滾動(dòng)軸承故障進(jìn)行早期預(yù)報(bào)，并能反映故障的發(fā)展變化趨勢(shì)。當(dāng)滾動(dòng)軸承無(wú)故障時(shí)，XP/Xrms，為一較小的穩(wěn)定值；一旦軸承出現(xiàn)了損傷，則會(huì)產(chǎn)生沖擊信號(hào)，振動(dòng)峰值明顯增大，但此時(shí)均方根值尚無(wú)明顯的增大，故XP/Xrms增大；當(dāng)故障不斷擴(kuò)展，峰值逐步達(dá)到極限值后，均方根值則開(kāi)始增大，XP/Xrms逐步減小，直至恢復(fù)到無(wú)故障時(shí)的大小。

</p><p>自潤(rùn)滑軸承<p>自潤(rùn)滑軸承是采用以保持架作潤(rùn)滑源的轉(zhuǎn)移潤(rùn)滑方法，維持軸承正常運(yùn)轉(zhuǎn)的一種特殊軸承。自潤(rùn)滑軸承結(jié)構(gòu)多為單列角接觸球軸承和向心短圓柱滾子軸承。<p>陶瓷軸承<p>陶瓷軸承可以應(yīng)用于高速、高溫、低溫、強(qiáng)腐蝕、強(qiáng)磁場(chǎng)、真空、高壓等各種惡劣的工況。陶瓷軸承的主要特性是:承載能力高，耐熱性好、極限轉(zhuǎn)速高、摩擦溫升小、摩擦損失小、耐久性高、耐腐蝕性好、絕緣性好、導(dǎo)磁率低、自潤(rùn)滑性好。<p>高速軸承<p>通常將Dm?n值超過(guò)1.0×106mm?r/min的滾動(dòng)軸承稱為高速軸承。這里，Dm為滾動(dòng)體的中心圓(節(jié)圓)直徑，n為內(nèi)圈的轉(zhuǎn)速。目前在實(shí)際應(yīng)用中，高速軸承的Dm?n值已達(dá)到3.0×106mm?r/min，本世紀(jì)初，高速軸承的Dm?n值可達(dá)到3.5×106mm?r/min。<p><br/>勒盾 ABL 軸承是一家高精度精密軸承專業(yè)制造商；提供日本NTN軸承 4T-A4059/A4138 ；<div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="浙江ABLUCP314,ABL"

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(kāi)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。 </p> <p>
