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下5點故障。

1.主傳動電(dian)機(ji)(ji)運轉(zhuan)(zhuan)(zhuan)不正(zheng)常(chang)滑(hua)差電(dian)機(ji)(ji)在運轉(zhuan)(zhuan)(zhuan)過程中會劇烈(lie)振(zhen)動，引起軸(zhou)(zhou)(zhou)承(cheng)發熱。拆開(kai)離(li)合器電(dian)樞與磁轉(zhuan)(zhuan)(zhuan)子，檢查電(dian)機(ji)(ji)的軸(zhou)(zhou)(zhou)承(cheng)是否(fou)嚴重缺乏潤滑(hua)油脂，而造成(cheng)軸(zhou)(zhou)(zhou)承(cheng)嚴重磨損，電(dian)動機(ji)(ji)的運轉(zhuan)(zhuan)(zhuan)性能下降。此時(shi)需(xu)要更換已損壞(huai)的軸(zhou)(zhou)(zhou)承(cheng)，并加(jia)(jia)注好(hao)潤滑(hua)油脂。正(zheng)常(chang)情況下，應對這部分(fen)機(ji)(ji)構(gou)的所(suo)有部件進行(xing)一次清洗、加(jia)(jia)油，以主傳動電(dian)機(ji)(ji)的正(zheng)常(chang)運行(xing)。

2.主(zhu)機(ji)(ji)轉(zhuan)速(su)周(zhou)期性下降(jiang)出(chu)現這種(zhong)情(qing)況，大多(duo)數是因機(ji)(ji)械部(bu)分發生了(le)故(gu)障所引起，調速(su)電機(ji)(ji)的膠(jiao)輥比較(jiao)多(duo)，每根膠(jiao)輥靠軸(zhou)承來支(zhi)撐動(dong)彈。如果某(mou)根膠(jiao)輥的一端軸(zhou)承發生了(le)故(gu)障，都可(ke)能使主(zhu)機(ji)(ji)的轉(zhuan)速(su)周(zhou)期性地(di)下峰，嚴重時，主(zhu)機(ji)(ji)動(dong)彈會更加挫折(zhe)，應當即更換軸(zhou)承才(cai)行。另(ling)外，應該注意主(zhu)機(ji)(ji)各滾筒(包括印(yin)版(ban)，橡皮、壓印(yin)滾筒)的軸(zhou)承及其潤(run)滑部(bu)位的工作情(qing)況是否正常，如果發生故(gu)障同樣會影響(xiang)印(yin)刷(shua)速(su)度。

3.齒輪減速(su)(su)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)升速(su)(su)后機(ji)(ji)(ji)(ji)(ji)(ji)(ji)速(su)(su)又(you)逐漸(jian)(jian)下(xia)降以(yi)(yi)至停機(ji)(ji)(ji)(ji)(ji)(ji)(ji)出(chu)現這(zhe)種情況(kuang)，需要觀(guan)察調速(su)(su)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)柜(ju)里的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)表指(zhi)針的(de)(de)(de)(de)變(bian)化(hua)。如(ru)果(guo)其(qi)指(zhi)示電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)急劇(ju)增(zeng)大，則主(zhu)(zhu)(zhu)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)(de)熱(re)(re)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)等(deng)過載(zai)保(bao)護裝(zhuang)(zhuang)置必然會產生保(bao)護動作(zuo)，使主(zhu)(zhu)(zhu)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)斷開三相電(dian)(dian)(dian)(dian)(dian)(dian)源而(er)住手(shou)運(yun)轉。這(zhe)時需要認真(zhen)檢查主(zhu)(zhu)(zhu)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)回路的(de)(de)(de)(de)有(you)關接(jie)(jie)線(xian)(xian)元(yuan)件(jian)及(ji)主(zhu)(zhu)(zhu)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)(de)交流(liu)(liu)(liu)接(jie)(jie)觸(chu)(chu)器(qi)，調速(su)(su)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)柜(ju)里的(de)(de)(de)(de)所有(you)熱(re)(re)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)等(deng)過載(zai)保(bao)護裝(zhuang)(zhuang)置的(de)(de)(de)(de)接(jie)(jie)線(xian)(xian)部位是(shi)否松動，接(jie)(jie)觸(chu)(chu)是(shi)否不(bu)良(liang)(liang)而(er)發(fa)熱(re)(re)。如(ru)果(guo)這(zhe)些(xie)部位有(you)標(biao)(biao)題(ti)題(ti)目，則會在(zai)(zai)主(zhu)(zhu)(zhu)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)增(zeng)速(su)(su)后，由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)路中的(de)(de)(de)(de)導線(xian)(xian)和元(yuan)件(jian)接(jie)(jie)觸(chu)(chu)不(bu)良(liang)(liang)使電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)迅(xun)速(su)(su)增(zeng)大，而(er)引起保(bao)護性(xing)的(de)(de)(de)(de)停機(ji)(ji)(ji)(ji)(ji)(ji)(ji)。當(dang)調速(su)(su)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)運(yun)轉速(su)(su)度(du)較(jiao)低時，由(you)于主(zhu)(zhu)(zhu)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)(de)工作(zuo)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)較(jiao)小而(er)不(bu)會發(fa)生氣(qi)(qi)希望(wang)速(su)(su)逐漸(jian)(jian)下(xia)降以(yi)(yi)至停機(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)(de)情況(kuang)，但是(shi)，當(dang)調速(su)(su)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)升速(su)(su)時，用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)負(fu)荷大，電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)元(yuan)件(jian)的(de)(de)(de)(de)故障就(jiu)會顯露出(chu)來。在(zai)(zai)實際工作(zuo)中，有(you)時可以(yi)(yi)看到調速(su)(su)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)柜(ju)內的(de)(de)(de)(de)接(jie)(jie)線(xian)(xian)端(duan)子(zi)(zi)由(you)于導線(xian)(xian)接(jie)(jie)觸(chu)(chu)不(bu)良(liang)(liang)而(er)發(fa)熱(re)(re)，甚(shen)至在(zai)(zai)連接(jie)(jie)處出(chu)現氧(yang)化(hua)物(wu)層，導線(xian)(xian)的(de)(de)(de)(de)絕(jue)緣外(wai)反(fan)燒焦變(bian)色(se)，這(zhe)些(xie)標(biao)(biao)題(ti)題(ti)目都會嚴重影響主(zhu)(zhu)(zhu)傳動電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)(de)正常運(yun)轉。這(zhe)時需要操作(zuo)人員(yuan)當(dang)即采取相應措施，如(ru)清理(li)接(jie)(jie)線(xian)(xian)端(duan)子(zi)(zi)和導線(xian)(xian)的(de)(de)(de)(de)接(jie)(jie)觸(chu)(chu)面(mian)，緊固接(jie)(jie)線(xian)(xian)螺釘，去(qu)除(chu)燒壞了的(de)(de)(de)(de)導線(xian)(xian)氧(yang)化(hua)物(wu)層，更換損(sun)壞嚴重的(de)(de)(de)(de)接(jie)(jie)線(xian)(xian)端(duan)子(zi)(zi)等(deng)。

4.主(zhu)傳(chuan)動電(dian)(dian)機(ji)運轉(zhuan)時噪聲較大為了調(diao)整(zheng)滑差(cha)電(dian)(dian)機(ji)動平(ping)衡(heng)(heng)，其電(dian)(dian)樞(shu)和(he)磁(ci)轉(zhuan)子的(de)兩端分別裝有配重(zhong)(zhong)裝置(zhi)(zhi)。如果這(zhe)部(bu)分裝置(zhi)(zhi)稍有松動，那么滑差(cha)電(dian)(dian)機(ji)在速動彈時就(jiu)會偏離原釆(bian)的(de)位置(zhi)(zhi)。故障(zhang)如果發(fa)生在主(zhu)傳(chuan)動電(dian)(dian)機(ji)的(de)外瑞面(mian)，就(jiu)會造成電(dian)(dian)樞(shu)和(he)磁(ci)轉(zhuan)子的(de)局部(bu)摩(mo)擦(ca)，使(shi)噪聲加大。這(zhe)時就(jiu)需要停機(ji)修理(li)，恢復電(dian)(dian)樞(shu)和(he)磁(ci)轉(zhuan)子的(de)動平(ping)衡(heng)(heng)，并(bing)重(zhong)(zhong)新找好原動平(ping)衡(heng)(heng)配重(zhong)(zhong)的(de)位置(zhi)(zhi)并(bing)將其固定好，使(shi)主(zhu)傳(chuan)動電(dian)(dian)機(ji)正常(chang)運轉(zhuan)。

5.主傳動(dong)電(dian)(dian)(dian)機(ji)制動(dong)電(dian)(dian)(dian)磁(ci)離合(he)(he)器(qi)(qi)燒毀必須保持(chi)調速(su)電(dian)(dian)(dian)機(ji)制動(dong)離合(he)(he)器(qi)(qi)的(de)(de)(de)(de)磁(ci)軛、銜鐵、摩擦(ca)片(pian)等(deng)部位的(de)(de)(de)(de)清潔，無油污(wu)和雜(za)物。據(ju)知，無論電(dian)(dian)(dian)氣(qi)元(yuan)件，如(ru)果黏附上過多的(de)(de)(de)(de)紙毛、塵(chen)埃和金屬屑等(deng)雜(za)質(zhi)，工作(zuo)時(shi)間一長(chang)(chang)，就(jiu)等(deng)閑使電(dian)(dian)(dian)氣(qi)元(yuan)件發熱(re)、接觸(chu)不(bu)良，而且摩擦(ca)片(pian)中(zhong)的(de)(de)(de)(de)這(zhe)些雜(za)質(zhi)加大了(le)離合(he)(he)器(qi)(qi)在不(bu)吸合(he)(he)上作(zuo)時(shi)的(de)(de)(de)(de)摩擦(ca)負(fu)荷和損害。此時(shi)，電(dian)(dian)(dian)氣(qi)元(yuan)件由于(yu)接觸(chu)不(bu)良而不(bu)吸合(he)(he)，使其溫度(du)升，制動(dong)電(dian)(dian)(dian)磁(ci)離合(he)(he)器(qi)(qi)線圈的(de)(de)(de)(de)絕緣便會(hui)過早受(shou)到損害，以(yi)致后被燒毀。因此要特(te)別注意維(wei)護保養(yang)，定期用(yong)毛刷蘸汽油刷洗摩擦(ca)片(pian)等(deng)部件上的(de)(de)(de)(de)油污(wu)等(deng)雜(za)質(zhi)，對調速(su)電(dian)(dian)(dian)機(ji)電(dian)(dian)(dian)氣(qi)柜內所(suo)有電(dian)(dian)(dian)氣(qi)元(yuan)件上面的(de)(de)(de)(de)紙毛、灰(hui)塵(chen)等(deng)雜(za)質(zhi)進行清理，以(yi)利于(yu)離合(he)(he)器(qi)(qi)散熱(re)通風，減少損耗，降低工作(zuo)溫度(du)，延長(chang)(chang)電(dian)(dian)(dian)氣(qi)元(yuan)件使用(yong)壽(shou)命。
