3、零部件松動(dòng)
在安裝時(shí)由于個(gè)別零部件的松動(dòng)(如軸承預(yù)緊機(jī)構(gòu)，軸系定位機(jī)構(gòu)等)，導(dǎo)致系統(tǒng)定位不準(zhǔn)，非正常位置嚙合，軸系移動(dòng)，產(chǎn)生振動(dòng)和噪聲。這一系列需從設(shè)計(jì)結(jié)構(gòu)出發(fā)，盡量保證各機(jī)構(gòu)的聯(lián)接穩(wěn)定，采用多種聯(lián)接方式。
4、傳動(dòng)部件損壞
在安裝時(shí)由于不當(dāng)操作損傷傳動(dòng)部件，導(dǎo)致系統(tǒng)運(yùn)動(dòng)不準(zhǔn)確或運(yùn)動(dòng)失穩(wěn);高速運(yùn)動(dòng)部件由于受損導(dǎo)致油膜振動(dòng);人為造成運(yùn)動(dòng)件動(dòng)不平衡;都產(chǎn)生振動(dòng)和噪聲。這些原因在安裝過(guò)程中都是必須注意和盡量避免的。對(duì)無(wú)法修復(fù)的損傷零部件，必須予以更換，以保證系統(tǒng)獲得穩(wěn)定的噪聲等級(jí)。
減速機(jī)噪音大的解決辦法之二：使用與維護(hù)
減速機(jī)的正確使用維護(hù)雖不能降低系統(tǒng)噪聲等級(jí)，保證傳遞精度，但卻能防止其指標(biāo)劣化，增大使用壽命。
1、內(nèi)部清潔
減速機(jī)內(nèi)部零件的清潔是保證其正常運(yùn)轉(zhuǎn)的基本條件，任何雜質(zhì)污物的進(jìn)入都將影響并損傷傳動(dòng)系統(tǒng)，導(dǎo)致噪聲的產(chǎn)生。
2、工作溫度
保證減速機(jī)正常的工作溫度，避免零部件因過(guò)大的溫升產(chǎn)生變形，確保齒輪正常嚙合，從而防止噪聲的增大。
3、及時(shí)的潤(rùn)滑和正確使用油品

一、直流發(fā)電機(jī)的基本工作原理
直流發(fā)電機(jī)和直流電動(dòng)機(jī)具有相同的結(jié)構(gòu)，只是直流發(fā)電機(jī)是由原動(dòng)機(jī)（一般是交流電動(dòng)機(jī)）拖動(dòng)旋轉(zhuǎn)而發(fā)電?？梢?jiàn)，它是把機(jī)械能變?yōu)殡娔艿脑O(shè)備。直流電動(dòng)機(jī)則接在直流電源上，拖動(dòng)各種工作機(jī)械（機(jī)床、泵、電車(chē)、電纜設(shè)備等）工作，它是把電能變?yōu)闄C(jī)械能的設(shè)備。但是，當(dāng)前已經(jīng)有可控硅整流裝置替代了直流發(fā)電機(jī)，為了能使大家更好的理解直流電動(dòng)機(jī)，有必要同時(shí)講述一下直流發(fā)電機(jī)的原理。
