企(qi)業的環境條(tiao)件較差，空氣中有(you)害物含量(liang)高，周轉場地太小，難以進行防銹(xiu)處理(li)。再加上天(tian)氣炎熱(re)，生(sheng)產工(gong)人違反防銹(xiu)規程等現(xian)象也不乏存在。 

滾(gun)動(dong)軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)在工作中允(yun)許有(you)輕微的運轉響(xiang)聲(sheng)(sheng)，如果響(xiang)聲(sheng)(sheng)過大或(huo)有(you)不(bu)正常的噪音或(huo)撞擊聲(sheng)(sheng)咯噔聲(sheng)(sheng)響(xiang)，則表明軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)有(you)故(gu)障。滾(gun)動(dong)軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)產(chan)(chan)生噪音的原因比較復雜，其一是(shi)軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)內、外圈配套表面(mian)磨(mo)損(sun)。而這(zhe)種磨(mo)損(sun)，破壞(huai)了軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)與殼體、軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)與軸(zhou)(zhou)(zhou)的配套關系(xi)，導致(zhi)軸(zhou)(zhou)(zhou)線偏離了正確的位置，軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)在有(you)負(fu)荷(he)時運轉產(chan)(chan)生異(yi)響(xiang)。當軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)疲勞時，其表面(mian)金屬(shu)剝落；也(ye)會使軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)徑(jing)向(xiang)間隙產(chan)(chan)生異(yi)響(xiang)。此(ci)外，軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)潤滑不(bu)足，形成(cheng)干摩擦，以及軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)破碎等都(dou)會產(chan)(chan)生異(yi)常的聲(sheng)(sheng)響(xiang)。軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)磨(mo)損(sun)松曠后，保持架松動(dong)損(sun)壞(huai)，也(ye)會產(chan)(chan)生異(yi)響(xiang)
