膠輥軸承和羅拉軸承的清洗、加油對(duì)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(shí)和三班機(jī)修工也都在過量給羅拉軸承加油,從而造成膠輥軸承在運(yùn)轉(zhuǎn)過程中溢出,油污浸入膠輥或膠圈的表面或內(nèi)部,導(dǎo)致膠輥膠圈在運(yùn)動(dòng)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(qiáng)膠輥膠圈的清潔,也很難對(duì)已經(jīng)浸透在膠輥膠圈內(nèi)的油污清潔干凈,從而影響運(yùn)轉(zhuǎn)效率,這也是棉紗產(chǎn)生油污、疵點(diǎn)的主要因素。改進(jìn)膠輥軸承的加油方式、控制加油量是保護(hù)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(hào)、加油量的多少、加油機(jī)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(duì)不同的紡紗設(shè)備羅拉軸承必須采用不同的油脂型號(hào)和加油方式加油,嚴(yán)格控制加油量,加油后的膠輥、羅拉軸承在運(yùn)行24h之內(nèi)無(wú)油污溢出是比較好的加油效果。如果膠輥、羅拉軸承在運(yùn)動(dòng)過程中有少量的油污溢出,必須迅速處理干凈,防止油污對(duì)羅拉、膠輥膠圈的污染,影響紡紗效果和紡紗質(zhì)量。

style="text-indent:25px">擠干輥加工時(shí)先按普通車削方法先加工出比較小截面圓弧回轉(zhuǎn)槽，其他截面可以通過數(shù)據(jù)編程控制不斷變化刀具進(jìn)給量進(jìn)行加工。車削過程中工件在高速旋轉(zhuǎn)，工件每轉(zhuǎn)一圈，刀具沿孔型截面圓弧的半徑方向變速往復(fù)進(jìn)給一次，刀架在段與段之間速度變化時(shí)會(huì)產(chǎn)生很大的加速度。為了避免刀架驅(qū)動(dòng)電機(jī)功率選擇過大，應(yīng)該通過計(jì)算優(yōu)化孔型曲線，在滿足精度要求的情況下，選取比較小的加速度。由于工件轉(zhuǎn)一圈刀架的轉(zhuǎn)動(dòng)進(jìn)給角度很小，分析時(shí)可認(rèn)為切削作用是在工件的一個(gè)截面上。擠干輥上墨會(huì)引起膠輥跳動(dòng)滑動(dòng)等情況，使印品出現(xiàn)水杠墨杠。</p><div
