膠輥軸承和羅拉軸承的清洗、加油對膠輥膠圈的影響在紡織廠不容易引起重視。通常膠輥軸承加油都是隨手任意往上涂,沒有量的控制,保全保養(yǎng)時和三班機修工也都在過量給羅拉軸承加油,從而造成膠輥軸承在運轉(zhuǎn)過程中溢出,油污浸入膠輥或膠圈的表面或內(nèi)部,導致膠輥膠圈在運動過程中老化龜裂,從而造成大量纏繞和損壞、損傷。即使紡紗廠加強膠輥膠圈的清潔,也很難對已經(jīng)浸透在膠輥膠圈內(nèi)的油污清潔干凈,從而影響運轉(zhuǎn)效率,這也是棉紗產(chǎn)生油污、疵點的主要因素。改進膠輥軸承的加油方式、控制加油量是保護膠輥膠圈不被腐蝕、浸透、損傷、損壞的因素之一。羅拉軸承加油的油脂型號、加油量的多少、加油機的擠壓次數(shù)是減少膠輥膠圈污染、損傷、損壞、龜裂、破裂的關(guān)鍵。因此對不同的紡紗設(shè)備羅拉軸承必須采用不同的油脂型號和加油方式加油,嚴格控制加油量,加油后的膠輥、羅拉軸承在運行24h之內(nèi)無油污溢出是比較好的加油效果。如果膠輥、羅拉軸承在運動過程中有少量的油污溢出,必須迅速處理干凈,防止油污對羅拉、膠輥膠圈的污染,影響紡紗效果和紡紗質(zhì)量。上海軋輥廠商哪家好軋輥的耐沖擊是對軋輥還有一些特殊要求。</p><div

style="text-indent:25px">高速鋼作為熱軋輥材料的應用在1988年始于日本，20世紀90年代初期美國和歐洲也進行了研制，我國在20世紀90年代后期開始研制和使用高速鋼軋輥。一般高速鋼的成分為1%～2%Ｃ，0%～5%Ｃｏ，0%～5%Ｎｂ，3%～10%Ｃｒ，2%～7%Ｍｏ，2%～7%Ｖ，1%～5%Ｗ。因為擁有大量可形成強碳化物的合金元素如Ｗ和Ｖ，其比較終的顯微組織含有大約10%～15%具有極高硬度和高溫穩(wěn)定性的碳化物，所以在高溫下工作能保持較高的強度和硬度。其工作層硬度高，可達到80～85ＨＳ，具有較好的耐磨性和抗熱裂性，軋輥表面沒有出現(xiàn)熱裂紋，一般沒有剝落現(xiàn)象。</p><p style="text-indent:25px">軋輥渦流檢測原理：渦流檢測是建立在電磁感應原理基礎(chǔ)之上的一種無損檢測方法，它適用于導電材料。當把一塊導體置于交變磁場之中，在導體中就有感應電流存在，即產(chǎn)生渦流。由于導體自身各種因素（如電導率、磁導率、形狀，尺寸和缺陷等）的變化，會導致渦流的變化，利用這種現(xiàn)象判定導體性質(zhì)，狀態(tài)的檢測方法，叫渦流檢測。渦流探傷的優(yōu)點：1、檢測時，線圈不需要接觸工件，也無需耦合介質(zhì)，所以檢測速度快。2、對工件表面或近表面的缺陷，有很高的檢出靈敏度，且在一定的范圍內(nèi)具有良好的線性指示，可用作質(zhì)量管理與控制。3、能測量金屬覆蓋層或非金屬涂層的厚度。冷軋輥主要失效形式包括劃傷、粘輥和剝落等。</p><div
