相信了解微型減速齒輪箱都知道它是由微(wei)型(xing)(xing)齒輪箱及(ji)微(wei)型(xing)(xing)電(dian)(dian)機(ji)組成的(de)(de)機(ji)電(dian)(dian)一體(ti)化產品，它所(suo)適用(yong)(yong)的(de)(de)領域也很廣。然而在(zai)日常的(de)(de)使(shi)用(yong)(yong)工作(zuo)當(dang)中微(wei)型(xing)(xing)減速(su)齒輪箱在(zai)使(shi)用(yong)(yong)過(guo)程中往往會出現一些故障(zhang)，下面(mian)是對微(wei)型(xing)(xing)減速(su)齒輪箱常見故障(zhang)及(ji)其發生原因的(de)(de)解析：

  1、不能起(qi)動：電(dian)源無電(dian)壓；勵磁回路斷卉；電(dian)刷回路斷開；有電(dian)源但電(dian)動機不能轉(zhuan)動。

  2、轉速不正(zheng)常：轉速過；轉速過低。

? 3、電(dian)(dian)刷(shua)(shua)(shua)火花過大：電(dian)(dian)刷(shua)(shua)(shua)不(bu)在中(zhong)性(xing)線上；電(dian)(dian)刷(shua)(shua)(shua)壓力不(bu)當(dang)或(huo)與換(huan)向器接觸不(bu)良或(huo)電(dian)(dian)刷(shua)(shua)(shua)磨(mo)損或(huo)電(dian)(dian)刷(shua)(shua)(shua)牌號(hao)不(bu)對；換(huan)向器表面不(bu)光滑或(huo)云母片凸出；電(dian)(dian)動機過載或(huo)電(dian)(dian)源電(dian)(dian)壓過；電(dian)(dian)樞繞(rao)組或(huo)磁繞(rao)組或(huo)換(huan)向繞(rao)組故障轉子動平衡未校(xiao)正好。

  4、過(guo)(guo)熱或冒煙(yan)：電(dian)(dian)動機長期過(guo)(guo)載；電(dian)(dian)源電(dian)(dian)壓(ya)過(guo)(guo)或過(guo)(guo)低；電(dian)(dian)樞、磁、換向(xiang)繞組故障；起動或正(zheng)、反(fan)轉過(guo)(guo)于(yu)頻繁。

  5、機座帶(dai)電：各繞組絕緣(yuan)(yuan)電阻太低；出線端與(yu)機座相接觸；各繞組絕緣(yuan)(yuan)損(sun)壞造(zao)成對(dui)地短(duan)路。
