水泥攪拌車軸承我國軸(zhou)承工(gong)(gong)業(ye)制(zhi)造工(gong)(gong)藝和工(gong)(gong)藝裝備(bei)技(ji)術發展緩慢(man)，車加(jia)工(gong)(gong)數控率低(di)，磨(mo)加(jia)工(gong)(gong)自(zi)動(dong)化水平低(di)，全國僅有200多(duo)條自(zi)動(dong)生產(chan)線。對軸(zhou)承壽命(ming)和可(ke)靠(kao)性(xing)至關重(zhong)要的(de)先(xian)進熱(re)處(chu)理工(gong)(gong)藝和裝備(bei)，如控制(zhi)氣氛保護加(jia)熱(re)、雙細化、貝氏體淬(cui)火等覆蓋率低(di)，許(xu)多(duo)技(ji)術難題攻(gong)關未能(neng)取得突破。軸(zhou)承鋼(gang)新鋼(gang)種的(de)研發，鋼(gang)材質(zhi)(zhi)(zhi)量的(de)提高，潤滑(hua)、冷(leng)卻、清洗(xi)和磨(mo)料磨(mo)具等相關技(ji)術的(de)研發，尚不(bu)能(neng)適應軸(zhou)承產(chan)品(pin)(pin)水平和質(zhi)(zhi)(zhi)量提高的(de)要求(qiu)。因而造成工(gong)(gong)序(xu)能(neng)力指數低(di)，一致性(xing)差，產(chan)品(pin)(pin)加(jia)工(gong)(gong)尺寸(cun)離(li)散度大，產(chan)品(pin)(pin)內在質(zhi)(zhi)(zhi)量不(bu)穩定而影響(xiang)軸(zhou)承的(de)精度、性(xing)能(neng)、壽命(ming)和可(ke)靠(kao)性(xing)。
