1軸承壞了,軸承溫度過高,滾道和滾動體有裂痕和傷痕。
潤滑油不足,老(lao)化或(huo)者(zhe)加多了(le),潤滑油不宜超過軸(zhou)承(cheng)蓋和軸(zhou)承(cheng)容積的七成。
潤滑(hua)油里邊有鐵(tie)粉(fen)等雜質(zhi),或(huo)者(zhe)里邊的油環(huan)被卡住了。
沒有(you)安裝(zhuang)到位,比如軸承,軸承蓋的(de)止口沒有(you)裝(zhuang)配,或者(zhe)兩(liang)者(zhe)之間過(guo)緊過(guo)松。同(tong)心度沒有(you)對好,存在偏心力引起損壞。
聯軸(zhou)(zhou)器水(shui)平沒有調整(zheng)好,傳動之間的鏈條或(huo)者皮帶太緊了,軸(zhou)(zhou)受到負載力(li)沖擊變形等。
軸(zhou)承(cheng)質量不行,軸(zhou)承(cheng)的間隙太小或者太大了。
電機啟(qi)停頻率(lv)過(guo)高,而(er)剛性(xing)又過(guo)大,對于一些場(chang)合不宜全壓啟(qi)動,軟啟(qi)動會(hui)好點。
2選型安裝使用問題
電機和(he)(he)負載之間水平沒有調整(zheng)好,造成負載和(he)(he)電機之間不同心而(er)存在徑向沖擊(ji)力。
電機腳的螺絲沒有固定好,或者固定架子沒有設計好。
沒有(you)考慮(lv)到(dao)負(fu)載情況來選型(xing),有(you)些負(fu)載是頻繁啟(qi)停(ting)的,也許計算起來只需(xu)要(yao)1KW的功(gong)率,設計上考慮(lv)到(dao)散熱和疲(pi)軟問題,可能需(xu)要(yao)3KW來使(shi)用(yong)。
線路接(jie)錯了(le),比(bi)如星(xing)型的(de)接(jie)成(cheng)了(le)三角型,而三角型的(de)接(jie)成(cheng)了(le)星(xing)型,這樣都可能(neng)引起電(dian)機內(nei)部(bu)過熱。
負載需要(yao)一些特殊的制動,電機(ji)并沒有對應(ying)的機(ji)械或者電子剎車,可能在停(ting)車時候來不及能量釋放。
電機沒有設(she)計一些保(bao)護裝(zhuang)置,比如過(guo)熱,過(guo)載,超溫,缺相等,這些都可能會(hui)在使用過(guo)程中發生的,但(dan)是因為保(bao)護不到(dao)位,直(zhi)接會(hui)把(ba)電機燒(shao)了。
接(jie)(jie)線(xian)錯誤,或(huo)者正反(fan)顛倒了(le),或(huo)者線(xian)選細了(le),或(huo)者端(duan)子線(xian)耳沒有壓好造(zao)成接(jie)(jie)觸電阻過大。
如(ru)果使用了光電編碼器之類的,需要考慮一些粉(fen)塵防(fang)(fang)護,防(fang)(fang)撞(zhuang)擊(ji)保護。
驅動器壞了引起(qi)電機這邊瞬間(jian)高壓或者大電流燒壞。
供(gong)電時候,沒有(you)考慮到電機耐壓(ya)問(wen)題(ti),比如220伏(fu)的,使(shi)用了380伏(fu)進(jin)去了。
一些步進電機和伺服電機,不能私(si)下拆開來更(geng)換軸承之類(lei)的,否則可能會丟磁(ci)或者(zhe)造成編碼器(qi)磁(ci)極(ji)零位偏移無法正常(chang)使用。
3環境問題
一些場合粉(fen)塵比較(jiao)多,如(ru)果(guo)使用了有(you)(you)刷直流電機,沒(mei)有(you)(you)留(liu)意安裝(zhuang)風(feng)機之類的裝(zhuang)置來及時疏通粉(fen)塵,導致碳刷和整流子短時間(jian)內磨(mo)損。
高溫(wen)場合,比如長(chang)期超過了50度,而負(fu)載(zai)又(you)比較重(zhong),選型電機時候,沒(mei)(mei)有(you)使用F和H這樣耐(nai)高溫(wen)的電機,同時又(you)沒(mei)(mei)有(you)設計單獨風冷系(xi)統,長(chang)期運行(xing)電機溫(wen)度過高。
環境濕度過高,沒(mei)有在用電絕緣方面做細節考慮,可能造成電路上漏電。
震(zhen)動(dong)大(da)的負載,要(yao)(yao)考(kao)慮(lv)共(gong)振(zhen)問(wen)題(ti),在固定電機時候,螺絲的方向要(yao)(yao)考(kao)慮(lv)是否會因為震(zhen)動(dong)方向差異而(er)松(song)動(dong)。
4電機質量問題
線圈繞組的(de)銅絲(si)不合格,或(huo)者繞的(de)圈數不夠,或(huo)者存在各相阻值不一樣等問題(ti)。
鼠籠導(dao)條轉子材料不過(guo)關,使用過(guo)程中斷(duan)裂。
電機絕緣不好,工廠供電有時候電網電壓會偏高,電壓稍微波動,引起絕緣擊穿。
一(yi)些(xie)永磁(ci)電機,磁(ci)性(xing)材料不耐高(gao)溫(wen),使用(yong)一(yi)段時間后(hou)失(shi)磁(ci)。
不管什么情況(kuang),使用(yong)電機過程中,只要震動大,噪音響,或者有(you)不尋常的味(wei)道,都要停機仔細檢查,確保沒有(you)問題后方可(ke)繼續使用(yong)。
