齒輪箱是機械傳動中廣泛應用的重要部件，一對齒輪嚙合時，由于不可避免地存在著齒距、齒形等誤差，在運轉過程中會產(chǎn)生嚙合沖擊而發(fā)生與齒輪嚙合頻率相對應的噪聲，齒面之間由于相對滑動也發(fā)生摩擦噪聲。由于齒輪是齒輪箱傳動中的基礎零件，降低齒輪噪聲對控制齒輪箱噪聲十分必要。一般來說，齒輪系統(tǒng)噪聲發(fā)生的原因主要有以下幾個方面：
1.齒輪設計方面。 參數(shù)選擇不當，重合度過小，齒廓修形不當或沒有修形，齒輪箱結構不合理等。齒輪加工方面 基節(jié)誤差和齒形誤差過大，齒側間隙過大，表面粗糙度過大等。
2. 齒輪系及齒輪箱方面。裝配偏心，接觸精度低，軸的平行度差，軸，軸承、支承的剛度不足，軸承的回轉精度不高及間隙不當?shù)取?br>
3. 其他方面輸入扭矩。負載扭矩的波動，軸系的扭振，電動機及其它傳動副的平衡情況等

二、通電后電動機不轉有嗡嗡聲
1．故障原因①轉子繞組有斷路（一相斷線）或電源一相失電；②繞組引出線始末端接錯或繞組內(nèi)部接反；③電源回路接點松動，接觸電阻大；④電動機負載過大或轉子卡??；⑤電源電壓過低；⑥小型電動機裝配太緊或軸承內(nèi)油脂過硬；⑦軸承卡住。
2．故障排除①查明斷點予以修復；②檢查繞組極性；判斷繞組末端是否正確；③緊固松動的接線螺絲，用萬用表判斷各接頭是否假接，予以修復；④減載或查出并消除機械故障，⑤檢查是否把規(guī)定的面接法誤接；是否由于電源導線過細使壓降過大，予以糾正，⑥重新裝配使之靈活；更換合格油脂；⑦修復軸承。
