兆威機電的從業經驗總結出，齒輪減速電機的電氣系統因保養不善常會出現以(yi)下5點(dian)故(gu)障。

1.主傳(chuan)動(dong)電(dian)(dian)機(ji)運(yun)轉不正(zheng)常(chang)滑(hua)差(cha)電(dian)(dian)機(ji)在運(yun)轉過(guo)程中會劇烈振動(dong)，引(yin)起軸(zhou)承(cheng)(cheng)發熱。拆開離合器電(dian)(dian)樞與磁轉子，檢查電(dian)(dian)機(ji)的(de)軸(zhou)承(cheng)(cheng)是否嚴重缺乏潤滑(hua)油(you)脂，而造成軸(zhou)承(cheng)(cheng)嚴重磨損，電(dian)(dian)動(dong)機(ji)的(de)運(yun)轉性能下降。此時需要更換已損壞的(de)軸(zhou)承(cheng)(cheng)，并加注好潤滑(hua)油(you)脂。正(zheng)常(chang)情況(kuang)下，應對這部(bu)分機(ji)構的(de)所有部(bu)件(jian)進行(xing)一(yi)次(ci)清洗、加油(you)，以主傳(chuan)動(dong)電(dian)(dian)機(ji)的(de)正(zheng)常(chang)運(yun)行(xing)。

2.主機(ji)(ji)轉速周(zhou)期性(xing)下(xia)降出現這(zhe)種情況，大多(duo)數是(shi)因機(ji)(ji)械部分發生(sheng)了(le)故(gu)障所引起，調(diao)速電機(ji)(ji)的(de)膠(jiao)輥(gun)比(bi)較(jiao)多(duo)，每(mei)根(gen)膠(jiao)輥(gun)靠軸(zhou)承(cheng)來支撐動(dong)彈(dan)。如果某根(gen)膠(jiao)輥(gun)的(de)一端軸(zhou)承(cheng)發生(sheng)了(le)故(gu)障，都可能使(shi)主機(ji)(ji)的(de)轉速周(zhou)期性(xing)地下(xia)峰(feng)，嚴重時(shi)，主機(ji)(ji)動(dong)彈(dan)會更(geng)加挫折，應當(dang)即更(geng)換軸(zhou)承(cheng)才(cai)行。另(ling)外，應該注意主機(ji)(ji)各滾筒(包括印(yin)版(ban)，橡皮、壓印(yin)滾筒)的(de)軸(zhou)承(cheng)及其(qi)潤滑部位的(de)工(gong)作情況是(shi)否(fou)正(zheng)常，如果發生(sheng)故(gu)障同樣(yang)會影響印(yin)刷速度。

3.齒(chi)輪(lun)減速(su)(su)(su)(su)電(dian)(dian)(dian)機(ji)(ji)升速(su)(su)(su)(su)后(hou)機(ji)(ji)速(su)(su)(su)(su)又逐漸(jian)下降(jiang)以至停(ting)機(ji)(ji)出現這(zhe)(zhe)種情況，需要(yao)觀察(cha)調(diao)(diao)速(su)(su)(su)(su)電(dian)(dian)(dian)機(ji)(ji)電(dian)(dian)(dian)氣柜(ju)里(li)的(de)(de)(de)電(dian)(dian)(dian)流表(biao)指(zhi)針的(de)(de)(de)變化。如果(guo)其指(zhi)示(shi)電(dian)(dian)(dian)流急劇增大，則(ze)主(zhu)(zhu)電(dian)(dian)(dian)機(ji)(ji)的(de)(de)(de)熱(re)繼電(dian)(dian)(dian)器(qi)(qi)等過載保護裝(zhuang)置必(bi)然會(hui)產生保護動作，使(shi)(shi)主(zhu)(zhu)電(dian)(dian)(dian)機(ji)(ji)斷開三相(xiang)電(dian)(dian)(dian)源(yuan)而(er)住手(shou)運(yun)轉。這(zhe)(zhe)時(shi)(shi)需要(yao)認真(zhen)檢查主(zhu)(zhu)電(dian)(dian)(dian)機(ji)(ji)回路的(de)(de)(de)有(you)關接(jie)線(xian)(xian)(xian)元件(jian)及主(zhu)(zhu)電(dian)(dian)(dian)機(ji)(ji)的(de)(de)(de)交流接(jie)觸器(qi)(qi)，調(diao)(diao)速(su)(su)(su)(su)電(dian)(dian)(dian)機(ji)(ji)電(dian)(dian)(dian)氣柜(ju)里(li)的(de)(de)(de)所有(you)熱(re)繼電(dian)(dian)(dian)器(qi)(qi)等過載保護裝(zhuang)置的(de)(de)(de)接(jie)線(xian)(xian)(xian)部位是否松動，接(jie)觸是否不良而(er)發熱(re)。如果(guo)這(zhe)(zhe)些部位有(you)標題題目(mu)，則(ze)會(hui)在主(zhu)(zhu)電(dian)(dian)(dian)機(ji)(ji)增速(su)(su)(su)(su)后(hou)，由(you)于(yu)電(dian)(dian)(dian)路中的(de)(de)(de)導(dao)線(xian)(xian)(xian)和元件(jian)接(jie)觸不良使(shi)(shi)電(dian)(dian)(dian)流迅速(su)(su)(su)(su)增大，而(er)引起(qi)保護性(xing)的(de)(de)(de)停(ting)機(ji)(ji)。當調(diao)(diao)速(su)(su)(su)(su)電(dian)(dian)(dian)機(ji)(ji)運(yun)轉速(su)(su)(su)(su)度(du)較(jiao)低時(shi)(shi)，由(you)于(yu)主(zhu)(zhu)電(dian)(dian)(dian)機(ji)(ji)的(de)(de)(de)工作電(dian)(dian)(dian)流較(jiao)小(xiao)而(er)不會(hui)發生氣希望速(su)(su)(su)(su)逐漸(jian)下降(jiang)以至停(ting)機(ji)(ji)的(de)(de)(de)情況，但(dan)是，當調(diao)(diao)速(su)(su)(su)(su)電(dian)(dian)(dian)機(ji)(ji)升速(su)(su)(su)(su)時(shi)(shi)，用電(dian)(dian)(dian)負荷大，電(dian)(dian)(dian)氣元件(jian)的(de)(de)(de)故(gu)障就(jiu)會(hui)顯露出來。在實(shi)際工作中，有(you)時(shi)(shi)可以看到(dao)調(diao)(diao)速(su)(su)(su)(su)電(dian)(dian)(dian)機(ji)(ji)電(dian)(dian)(dian)氣柜(ju)內(nei)的(de)(de)(de)接(jie)線(xian)(xian)(xian)端子(zi)由(you)于(yu)導(dao)線(xian)(xian)(xian)接(jie)觸不良而(er)發熱(re)，甚至在連接(jie)處出現氧化物層，導(dao)線(xian)(xian)(xian)的(de)(de)(de)絕緣外反(fan)燒焦變色，這(zhe)(zhe)些標題題目(mu)都會(hui)嚴重影響主(zhu)(zhu)傳(chuan)動電(dian)(dian)(dian)機(ji)(ji)的(de)(de)(de)正常運(yun)轉。這(zhe)(zhe)時(shi)(shi)需要(yao)操作人員當即采取(qu)相(xiang)應措施(shi)，如清理(li)接(jie)線(xian)(xian)(xian)端子(zi)和導(dao)線(xian)(xian)(xian)的(de)(de)(de)接(jie)觸面，緊固(gu)接(jie)線(xian)(xian)(xian)螺釘(ding)，去除燒壞(huai)(huai)了的(de)(de)(de)導(dao)線(xian)(xian)(xian)氧化物層，更(geng)換(huan)損(sun)壞(huai)(huai)嚴重的(de)(de)(de)接(jie)線(xian)(xian)(xian)端子(zi)等。

4.主傳(chuan)動(dong)電(dian)機(ji)運轉時噪聲較大為(wei)了(le)調整滑差電(dian)機(ji)動(dong)平衡，其電(dian)樞(shu)(shu)和磁(ci)(ci)轉子(zi)的(de)兩端分(fen)別裝(zhuang)(zhuang)有配(pei)重(zhong)(zhong)裝(zhuang)(zhuang)置。如果這部分(fen)裝(zhuang)(zhuang)置稍(shao)有松動(dong)，那么滑差電(dian)機(ji)在(zai)速動(dong)彈時就會(hui)偏離原釆的(de)位(wei)置。故障(zhang)如果發生在(zai)主傳(chuan)動(dong)電(dian)機(ji)的(de)外(wai)瑞面(mian)，就會(hui)造成電(dian)樞(shu)(shu)和磁(ci)(ci)轉子(zi)的(de)局(ju)部摩(mo)擦(ca)，使噪聲加大。這時就需要停機(ji)修理，恢復(fu)電(dian)樞(shu)(shu)和磁(ci)(ci)轉子(zi)的(de)動(dong)平衡，并重(zhong)(zhong)新找好原動(dong)平衡配(pei)重(zhong)(zhong)的(de)位(wei)置并將其固定好，使主傳(chuan)動(dong)電(dian)機(ji)正常運轉。

5.主(zhu)傳動(dong)電(dian)(dian)(dian)(dian)機制(zhi)動(dong)電(dian)(dian)(dian)(dian)磁(ci)(ci)離(li)合(he)器(qi)燒毀必(bi)須保持調速(su)電(dian)(dian)(dian)(dian)機制(zhi)動(dong)離(li)合(he)器(qi)的(de)(de)(de)磁(ci)(ci)軛、銜鐵(tie)、摩(mo)擦(ca)片(pian)等(deng)部位的(de)(de)(de)清潔，無(wu)油污和雜物。據知，無(wu)論電(dian)(dian)(dian)(dian)氣(qi)(qi)元(yuan)(yuan)件，如果黏附上過多的(de)(de)(de)紙(zhi)毛、塵埃(ai)和金(jin)屬屑等(deng)雜質(zhi)，工作(zuo)(zuo)時間一長，就等(deng)閑使電(dian)(dian)(dian)(dian)氣(qi)(qi)元(yuan)(yuan)件發熱(re)、接(jie)觸(chu)不良，而(er)且(qie)摩(mo)擦(ca)片(pian)中的(de)(de)(de)這(zhe)些雜質(zhi)加大了離(li)合(he)器(qi)在不吸合(he)上作(zuo)(zuo)時的(de)(de)(de)摩(mo)擦(ca)負荷(he)和損害。此時，電(dian)(dian)(dian)(dian)氣(qi)(qi)元(yuan)(yuan)件由于接(jie)觸(chu)不良而(er)不吸合(he)，使其溫度(du)(du)升，制(zhi)動(dong)電(dian)(dian)(dian)(dian)磁(ci)(ci)離(li)合(he)器(qi)線圈的(de)(de)(de)絕(jue)緣便會過早受到(dao)損害，以致后被燒毀。因此要特別注意維護(hu)保養(yang)，定期用(yong)毛刷蘸汽油刷洗摩(mo)擦(ca)片(pian)等(deng)部件上的(de)(de)(de)油污等(deng)雜質(zhi)，對調速(su)電(dian)(dian)(dian)(dian)機電(dian)(dian)(dian)(dian)氣(qi)(qi)柜內所有電(dian)(dian)(dian)(dian)氣(qi)(qi)元(yuan)(yuan)件上面的(de)(de)(de)紙(zhi)毛、灰(hui)塵等(deng)雜質(zhi)進行清理，以利于離(li)合(he)器(qi)散熱(re)通風，減(jian)少損耗(hao)，降低工作(zuo)(zuo)溫度(du)(du)，延長電(dian)(dian)(dian)(dian)氣(qi)(qi)元(yuan)(yuan)件使用(yong)壽(shou)命。
