兆威機電的從業經驗總結出，齒輪減速電機的電(dian)氣系(xi)統因保養(yang)不善常會出(chu)現以(yi)下(xia)5點故(gu)障。

1.主(zhu)驅(qu)動(dong)電(dian)機(ji)(ji)運(yun)轉(zhuan)不正(zheng)(zheng)常滑差電(dian)機(ji)(ji)在運(yun)轉(zhuan)過程中會劇(ju)烈振(zhen)動(dong)，引起軸承(cheng)發熱。拆(chai)開離合器(qi)電(dian)樞與磁轉(zhuan)子，檢查(cha)電(dian)機(ji)(ji)的軸承(cheng)是(shi)否(fou)嚴重(zhong)缺乏潤滑油(you)脂(zhi)，而造(zao)成軸承(cheng)嚴重(zhong)磨損，電(dian)動(dong)機(ji)(ji)的運(yun)轉(zhuan)性能下降。此時需要更(geng)換已損壞的軸承(cheng)，并加注(zhu)好(hao)潤滑油(you)脂(zhi)。正(zheng)(zheng)常情況(kuang)下，應對(dui)這部(bu)(bu)分(fen)機(ji)(ji)構的所有(you)部(bu)(bu)件進行(xing)一次清洗、加油(you)，以主(zhu)驅(qu)動(dong)電(dian)機(ji)(ji)的正(zheng)(zheng)常運(yun)行(xing)。

2.主機(ji)(ji)轉速(su)周期性(xing)下降出現這種(zhong)情況(kuang)，大(da)多(duo)數(shu)是因機(ji)(ji)械部(bu)分發生(sheng)了故(gu)障(zhang)所(suo)引起，調速(su)電機(ji)(ji)的膠輥比(bi)較多(duo)，每(mei)根膠輥靠軸承(cheng)來支撐動彈。如果某(mou)根膠輥的一(yi)端軸承(cheng)發生(sheng)了故(gu)障(zhang)，都可(ke)能使主機(ji)(ji)的轉速(su)周期性(xing)地(di)下峰，嚴重時，主機(ji)(ji)動彈會(hui)更加挫折(zhe)，應(ying)當(dang)即更換(huan)軸承(cheng)才行。另外，應(ying)該注意主機(ji)(ji)各(ge)滾筒(tong)(包括(kuo)印(yin)版，橡皮、壓(ya)印(yin)滾筒(tong))的軸承(cheng)及其潤(run)滑部(bu)位的工(gong)作情況(kuang)是否正常(chang)，如果發生(sheng)故(gu)障(zhang)同樣會(hui)影響印(yin)刷速(su)度。

3.齒(chi)輪減速(su)(su)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)升速(su)(su)后機(ji)(ji)(ji)(ji)(ji)(ji)速(su)(su)又逐漸下(xia)降(jiang)以(yi)至停機(ji)(ji)(ji)(ji)(ji)(ji)出現這(zhe)種情況(kuang)(kuang)，需要觀(guan)察調(diao)速(su)(su)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)電(dian)(dian)(dian)氣(qi)柜(ju)里的(de)電(dian)(dian)(dian)流(liu)表指(zhi)針(zhen)的(de)變(bian)化(hua)。如(ru)果其指(zhi)示電(dian)(dian)(dian)流(liu)急劇增大，則主電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)的(de)熱(re)繼電(dian)(dian)(dian)器(qi)等(deng)(deng)過載(zai)保護(hu)(hu)裝置(zhi)必然會(hui)(hui)產生保護(hu)(hu)動作，使主電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)斷開三相電(dian)(dian)(dian)源(yuan)而(er)(er)住手(shou)運轉(zhuan)。這(zhe)時(shi)(shi)(shi)需要認真檢查(cha)主電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)回路的(de)有(you)(you)關接(jie)(jie)線(xian)(xian)元(yuan)件及主電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)的(de)交(jiao)流(liu)接(jie)(jie)觸器(qi)，調(diao)速(su)(su)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)電(dian)(dian)(dian)氣(qi)柜(ju)里的(de)所有(you)(you)熱(re)繼電(dian)(dian)(dian)器(qi)等(deng)(deng)過載(zai)保護(hu)(hu)裝置(zhi)的(de)接(jie)(jie)線(xian)(xian)部(bu)(bu)位(wei)是否松動，接(jie)(jie)觸是否不良(liang)而(er)(er)發(fa)熱(re)。如(ru)果這(zhe)些部(bu)(bu)位(wei)有(you)(you)標題(ti)題(ti)目，則會(hui)(hui)在主電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)增速(su)(su)后，由于(yu)電(dian)(dian)(dian)路中的(de)導線(xian)(xian)和(he)元(yuan)件接(jie)(jie)觸不良(liang)使電(dian)(dian)(dian)流(liu)迅(xun)速(su)(su)增大，而(er)(er)引起(qi)保護(hu)(hu)性的(de)停機(ji)(ji)(ji)(ji)(ji)(ji)。當調(diao)速(su)(su)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)運轉(zhuan)速(su)(su)度(du)較(jiao)低時(shi)(shi)(shi)，由于(yu)主電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)的(de)工(gong)作電(dian)(dian)(dian)流(liu)較(jiao)小而(er)(er)不會(hui)(hui)發(fa)生氣(qi)希望速(su)(su)逐漸下(xia)降(jiang)以(yi)至停機(ji)(ji)(ji)(ji)(ji)(ji)的(de)情況(kuang)(kuang)，但是，當調(diao)速(su)(su)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)升速(su)(su)時(shi)(shi)(shi)，用電(dian)(dian)(dian)負荷大，電(dian)(dian)(dian)氣(qi)元(yuan)件的(de)故(gu)障就會(hui)(hui)顯露出來(lai)。在實際工(gong)作中，有(you)(you)時(shi)(shi)(shi)可以(yi)看(kan)到(dao)調(diao)速(su)(su)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)電(dian)(dian)(dian)氣(qi)柜(ju)內的(de)接(jie)(jie)線(xian)(xian)端(duan)子(zi)由于(yu)導線(xian)(xian)接(jie)(jie)觸不良(liang)而(er)(er)發(fa)熱(re)，甚至在連(lian)接(jie)(jie)處出現氧化(hua)物(wu)層，導線(xian)(xian)的(de)絕(jue)緣(yuan)外反燒焦變(bian)色，這(zhe)些標題(ti)題(ti)目都(dou)會(hui)(hui)嚴重影響主驅動電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)的(de)正(zheng)常運轉(zhuan)。這(zhe)時(shi)(shi)(shi)需要操作人員(yuan)當即(ji)采取相應措施(shi)，如(ru)清(qing)理接(jie)(jie)線(xian)(xian)端(duan)子(zi)和(he)導線(xian)(xian)的(de)接(jie)(jie)觸面(mian)，緊固(gu)接(jie)(jie)線(xian)(xian)螺釘，去除燒壞了的(de)導線(xian)(xian)氧化(hua)物(wu)層，更換損(sun)壞嚴重的(de)接(jie)(jie)線(xian)(xian)端(duan)子(zi)等(deng)(deng)。

4.主(zhu)驅動(dong)(dong)電(dian)(dian)(dian)(dian)機(ji)(ji)運轉(zhuan)時噪聲(sheng)較(jiao)大為了(le)調整滑(hua)差電(dian)(dian)(dian)(dian)機(ji)(ji)動(dong)(dong)平(ping)衡(heng)(heng)，其(qi)電(dian)(dian)(dian)(dian)樞和磁(ci)轉(zhuan)子的(de)兩(liang)端分別(bie)裝有(you)(you)配重(zhong)裝置。如果這(zhe)部分裝置稍有(you)(you)松動(dong)(dong)，那么(me)滑(hua)差電(dian)(dian)(dian)(dian)機(ji)(ji)在(zai)速動(dong)(dong)彈時就會偏離原釆的(de)位置。故(gu)障如果發生在(zai)主(zhu)驅動(dong)(dong)電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)外瑞面，就會造成電(dian)(dian)(dian)(dian)樞和磁(ci)轉(zhuan)子的(de)局部摩擦(ca)，使噪聲(sheng)加大。這(zhe)時就需要停機(ji)(ji)修(xiu)理，恢復電(dian)(dian)(dian)(dian)樞和磁(ci)轉(zhuan)子的(de)動(dong)(dong)平(ping)衡(heng)(heng)，并重(zhong)新找好原動(dong)(dong)平(ping)衡(heng)(heng)配重(zhong)的(de)位置并將其(qi)固定好，使主(zhu)驅動(dong)(dong)電(dian)(dian)(dian)(dian)機(ji)(ji)正常運轉(zhuan)。

5.主驅動電(dian)機制(zhi)動電(dian)磁(ci)(ci)離(li)合器燒毀必須保(bao)持調速(su)電(dian)機制(zhi)動離(li)合器的磁(ci)(ci)軛、銜鐵(tie)、摩(mo)擦(ca)片等部位的清潔(jie)，無(wu)油(you)(you)(you)污(wu)和雜(za)物。據知，無(wu)論電(dian)氣(qi)(qi)元(yuan)件(jian)，如果黏附上過多的紙毛(mao)、塵埃和金屬屑等雜(za)質，工(gong)作(zuo)(zuo)時間一長，就等閑使電(dian)氣(qi)(qi)元(yuan)件(jian)發熱、接觸(chu)不(bu)(bu)良，而且(qie)摩(mo)擦(ca)片中的這些雜(za)質加(jia)大了離(li)合器在不(bu)(bu)吸(xi)合上作(zuo)(zuo)時的摩(mo)擦(ca)負荷和損(sun)害。此(ci)時，電(dian)氣(qi)(qi)元(yuan)件(jian)由于接觸(chu)不(bu)(bu)良而不(bu)(bu)吸(xi)合，使其溫度(du)升，制(zhi)動電(dian)磁(ci)(ci)離(li)合器線(xian)圈(quan)的絕(jue)緣便會過早受到損(sun)害，以致后被燒毀。因(yin)此(ci)要特別注意維護保(bao)養，定期(qi)用毛(mao)刷(shua)蘸汽油(you)(you)(you)刷(shua)洗摩(mo)擦(ca)片等部件(jian)上的油(you)(you)(you)污(wu)等雜(za)質，對調速(su)電(dian)機電(dian)氣(qi)(qi)柜內所有電(dian)氣(qi)(qi)元(yuan)件(jian)上面的紙毛(mao)、灰塵等雜(za)質進(jin)行清理，以利于離(li)合器散熱通風，減少損(sun)耗，降低(di)工(gong)作(zuo)(zuo)溫度(du)，延長電(dian)氣(qi)(qi)元(yuan)件(jian)使用壽命。
