峭度系數(shù)診斷法。振幅滿足正態(tài)分布規(guī)律的無故障軸承，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。此方法的優(yōu)點(diǎn)在于與軸承的轉(zhuǎn)速、尺寸和載荷無關(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）。該值也是用于滾動軸承簡易診斷的有效指標(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）。該值用于滾動軸承簡易診斷的優(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，上海ABL注塑成型機(jī)軸承、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。通過對XP/Xrms值隨時間變化趨勢的監(jiān)測，可以有效地對滾動軸承故障進(jìn)行早期預(yù)報，并能反映故障的發(fā)展變化趨勢。當(dāng)滾動軸承無故障時，XP/Xrms，為一較小的穩(wěn)定值；一旦軸承出現(xiàn)了損傷，則會產(chǎn)生沖擊信號，振動峰值明顯增大，但此時均方根值尚無明顯的增大，故XP/Xrms增大；當(dāng)故障不斷擴(kuò)展，上海ABL注塑成型機(jī)軸承，峰值逐步達(dá)到極限值后，均方根值則開始增大，XP/Xrms逐步減小，直至恢復(fù)到無故障時的大小。

滾動軸承故障檢測的簡易診斷利用滾動軸承的振動信號分析故障診斷的方法可分為簡易診斷法和精密診斷法兩種。簡易診斷的目的是為了初步判斷被列為診斷對象的滾動軸承是否出現(xiàn)了故障；精密診斷的目的是要判斷在簡易診斷中被認(rèn)為出現(xiàn)了故障的軸承的故障類別及原因。下面主要介紹簡易診斷的幾種方法： </p> <p> （1）振幅值診斷法這里所說的振幅值指峰值XP、均值X（對于簡諧振動為半個周期內(nèi)的平均值，對于軸承沖擊振動為經(jīng)一定值處理后的平均值）以及均方根值（有效值）Xrms。這是一種是簡單、是常用的診斷法，它是通過將實(shí)測的振幅值與判定標(biāo)準(zhǔn)中給定的值進(jìn)行比較來診斷的。峰值反映的是某時刻振幅的是大值，因而它適用于像表面點(diǎn)蝕損傷之類的具有瞬時沖擊的故障診斷。均值用于診斷的效果與峰值基本一樣，其優(yōu)點(diǎn)是檢測值較峰值穩(wěn)定，但一般用于轉(zhuǎn)速較高的情況（如300r/min以上）。均方根值是對時間平均的，因而它適用于像磨損之類的振幅值隨時間緩慢變化的故障診斷。 </p> <p> （2）概率密度診斷法無故障滾動軸承振幅的概率密度曲線是典型的正態(tài)分布曲線；而一旦出現(xiàn)故障，則概率密度曲線可能出現(xiàn)偏斜或分散的現(xiàn)象。上海高精度引導(dǎo)的ABLABL軸承產(chǎn)品特點(diǎn)：良好的材料，產(chǎn)品精度高，可達(dá)上千個品種數(shù)百個品種；</p><div

這種理解并不***方面。對于沒有加清凈分散劑的潤滑油來說，顏色變黑的確是油品已嚴(yán)重變質(zhì)的表現(xiàn)，但現(xiàn)代機(jī)械軸承使用的潤滑油一般都加有清凈分解劑。 </p> <p> 軸承潤滑油 </p> <p> 這種清凈劑將粘附在活塞上的膠膜和黑色積炭洗滌下來，并分散在油中，減少高溫沉淀物的生成，故潤滑油使用一段時間后顏色容易變黑，但這時的油品并未完全變質(zhì)。 </p> <p> 積炭在汽缸內(nèi)呈紅熱狀態(tài)還容易引起早燃，如落入汽缸會加劇汽缸和活塞的磨損，還會加速污染潤滑油。其次，潤滑油過多增加了曲軸連桿的攪拌阻力，使燃油消耗增大。
