安裝非標軸(zhou)承(cheng)(cheng)(cheng)時,應(ying)檢(jian)驗軸(zhou)圈(quan)和軸(zhou)中(zhong)心(xin)線的垂直度。方法是將千分表(biao)(biao)(biao)固定于箱殼端面,使(shi)表(biao)(biao)(biao)的觸頭(tou)頂在軸(zhou)承(cheng)(cheng)(cheng)軸(zhou)圈(quan)滾(gun)(gun)道上(shang)邊轉(zhuan)動(dong)軸(zhou)承(cheng)(cheng)(cheng),邊觀察千分表(biao)(biao)(biao)指針(zhen),若指針(zhen)偏(pian)擺(bai),說明軸(zhou)圈(quan)和軸(zhou)中(zhong)心(xin)線不(bu)垂直。箱殼孔較深時,亦(yi)可(ke)用(yong)(yong)加長的千分表(biao)(biao)(biao)頭(tou)檢(jian)驗。軸(zhou)承(cheng)(cheng)(cheng)安裝正(zheng)確(que)(que)時,其座圈(quan)能(neng)自動(dong)適應(ying)滾(gun)(gun)動(dong)體(ti)(ti)的滾(gun)(gun)動(dong),確(que)(que)保(bao)(bao)滾(gun)(gun)動(dong)體(ti)(ti)位(wei)于上(shang)下圈(quan)滾(gun)(gun)道。如果裝反了,不(bu)僅軸(zhou)承(cheng)(cheng)(cheng)工作不(bu)正(zheng)常,且(qie)各(ge)配(pei)合面會遭(zao)到嚴重磨(mo)損。由于軸(zhou)圈(quan)與(yu)座圈(quan)和區別不(bu)很明顯(xian),裝配(pei)中(zhong)應(ying)格外小心(xin),切勿搞錯。此外,軸(zhou)承(cheng)(cheng)(cheng)的座圈(quan)與(yu)軸(zhou)承(cheng)(cheng)(cheng)座孔之間還應(ying)留有0.2—0.5mm的間隙(xi),用(yong)(yong)以補償零件加工、安裝不(bu)精確(que)(que)造(zao)成的誤差,當運(yun)轉(zhuan)中(zhong)軸(zhou)承(cheng)(cheng)(cheng)套圈(quan)中(zhong)心(xin)偏(pian)移時,此間隙(xi)可(ke)確(que)(que)保(bao)(bao)其自動(dong)調(diao)整(zheng),避免(mian)碰(peng)觸摩擦,使(shi)其正(zheng)常運(yun)轉(zhuan)。否(fou)則,將引起軸(zhou)承(cheng)(cheng)(cheng)劇烈損傷。
潤(run)滑(hua)(hua)(hua)對非(fei)標軸承(cheng)的(de)(de)運轉及壽命有(you)極為重要的(de)(de)影(ying)(ying)響,這里向您(nin)簡要介紹(shao)選擇潤(run)滑(hua)(hua)(hua)脂的(de)(de)一般原則。潤(run)滑(hua)(hua)(hua)脂由基(ji)(ji)(ji)礎(chu)油、增稠劑及添加劑制(zhi)成(cheng),不(bu)同(tong)(tong)(tong)種(zhong)(zhong)類和同(tong)(tong)(tong)一種(zhong)(zhong)類不(bu)同(tong)(tong)(tong)牌(pai)號的(de)(de)潤(run)滑(hua)(hua)(hua)脂性能(neng)相差(cha)很大(da),允許的(de)(de)旋轉極限不(bu)同(tong)(tong)(tong),在選擇時(shi)務必(bi)注(zhu)意。潤(run)滑(hua)(hua)(hua)脂的(de)(de)性能(neng)主要由基(ji)(ji)(ji)礎(chu)油決(jue)定,一般低(di)粘(zhan)度的(de)(de)基(ji)(ji)(ji)礎(chu)油適用(yong)于低(di)溫、高速,高粘(zhan)度的(de)(de)適用(yong)于高溫、高負荷(he)。增稠劑也關系著潤(run)滑(hua)(hua)(hua)性能(neng),增稠劑的(de)(de)耐水(shui)性決(jue)定潤(run)滑(hua)(hua)(hua)脂的(de)(de)耐水(shui)性。原則上,牌(pai)子不(bu)同(tong)(tong)(tong)的(de)(de)潤(run)滑(hua)(hua)(hua)脂不(bu)能(neng)混合,而且(qie),即(ji)使是同(tong)(tong)(tong)種(zhong)(zhong)增稠劑的(de)(de)潤(run)滑(hua)(hua)(hua)脂,也會因添加劑不(bu)同(tong)(tong)(tong)相互帶來(lai)壞影(ying)(ying)響。
