直流減速電機的軸(zhou)承不可以過(guo)緊？各位(wei)商友們知道嗎？那么造成直(zhi)流(liu)減速(su)電機軸(zhou)承過(guo)緊的原因(yin)是什(shen)么呢，今天兆(zhao)威機電就給大家簡單分析一下。一起來看(kan)看(kan)吧！

　 操(cao)作人員怕車廢端(duan)(duan)(duan)蓋(gai)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)室(shi)，直(zhi)流(liu)電(dian)機修(xiu)理時要使軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)外圈(quan)與(yu)端(duan)(duan)(duan)蓋(gai)配(pei)合(he)(he)公差合(he)(he)適。偏重采用(yong)公差范圍的(de)(de)下限，不(bu)愿車到(dao)上(shang)限，這(zhe)樣就使軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)室(shi)直(zhi)徑偏小(xiao)，增大了與(yu)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)外圈(quan)配(pei)合(he)(he)的(de)(de)過盈(ying)量(liang)；另外，修(xiu)理工人對(dui)于適當減(jian)(jian)少配(pei)合(he)(he)公差的(de)(de)大過盈(ying)量(liang)對(dui)直(zhi)流(liu)減(jian)(jian)速(su)電(dian)機的(de)(de)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)減(jian)(jian)少噪聲有好處(chu)的(de)(de)認(ren)識不(bu)夠，比(bi)方(fang)(fang)在拆微型直(zhi)流(liu)減(jian)(jian)速(su)電(dian)機軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)時發現軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)外圈(quan)與(yu)端(duan)(duan)(duan)蓋(gai)配(pei)合(he)(he)好拆，就誤認(ren)為軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)配(pei)合(he)(he)過松，說軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)“跳井了于是墊銅皮(pi)、打沖孔眼，甚(shen)至更(geng)換(huan)端(duan)(duan)(duan)蓋(gai)，或更(geng)換(huan)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)、擴大外圈(quan)直(zhi)徑來解決這(zhe)個問題，常見的(de)(de)方(fang)(fang)法是將端(duan)(duan)(duan)蓋(gai)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)室(shi)再擴大，然后鑲套，使軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)與(yu)端(duan)(duan)(duan)蓋(gai)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)室(shi)配(pei)合(he)(he)緊密，其結(jie)果造成直(zhi)流(liu)電(dian)機修(xiu)后軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)噪聲增加，軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)發熱(re)等不(bu)良(liang)現象(xiang)。由(you)于配(pei)合(he)(he)過緊，軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)發熱(re)，使潤滑脂被(bei)擠出去，軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)跑道（軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)工作面）局部無潤滑油(you)，軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)因過熱(re)而產生軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)故障。
