減速機技術資料：

減速器的噪聲是由于在它運轉過程中機內齒輪嚙合產生周期性的交變力對軸承、箱體的作用而引起的發生振動。評定圓柱齒輪減速器（以上簡稱減速器）質量水平的主要標準就是它的噪聲值。隨著產品標準的化，國家對減速器的噪聲值作出了更加嚴格的限定，這就要求對減速器的噪聲控制進行研究。
一、減速器中齒輪加工對減速器噪聲的影響
（一）齒輪加工誤差對噪聲的影響。
減小與控制齒輪噪聲是降低減速器噪聲的根本。為了降低齒輪噪聲，需從結構設計與齒輪精度兩方面來考慮。
1、低噪聲齒輪結構設計的要求。
齒輪結構設計對噪聲的影響是很重要的，理想的設計是：盡量提高輪齒的彎曲強度，選擇較大的變位系數與適當的螺旋角，使嚙合系數加大，從而達到降低噪音的目的。
2、齒輪制造精度對噪聲的影響。
對標準系列減速器來說，齒輪的制造精度決定著它的噪聲值。減速器齒輪的主要作用是傳遞轉速和扭矩，因此對它的齒輪制造精度要求，其工作平穩性等級是主要的。具有較高工作平穩性等級的齒輪不僅本身的使用壽命長，而且傳動中的沖擊、振動小，噪聲也就小，所以限制齒輪的工作平穩性誤差是減少齒輪噪聲的關鍵。? 
（二）工作平穩性精度對噪聲的影響。
齒輪的工作平穩性精度就是要求限制齒輪瞬時速比的變化，其誤差為齒輪每轉一周多次出現的轉角誤差，它使齒輪在嚙合過程中產生撞擊、振動從而產生齒輪的噪聲，它是一種高頻的沖擊聲。對于一個齒輪來說影響工作平穩性的因素是他的基節誤差和它的漸開線齒形誤差。?  
（三）齒輪的接觸精度對噪聲的影響。
評定齒輪接觸精度的綜合指標是接觸斑點，接觸不好的齒輪其噪聲必大。造成齒輪接觸不理想的原因有：齒向誤差影響齒長方向接觸，基節偏差與齒形誤差影響齒高方向的接觸。 
（四）齒輪的運動精度對噪聲的影響。
齒輪的運動精度是指傳遞運動的準確性，即齒輪每轉一周的轉角誤差zui大誤差值不能超過一定限度。由于齒輪運動精度是大周期性（齒輪旋轉一周）誤差，而由齒輪齒圈徑向跳動在齒輪旋轉一周內的周杰累計誤差會產生低頻噪聲，但當周節累計誤差增大時，將造成齒輪嚙合沖擊及角速度的變動，此時噪聲明顯增大并發出“隆隆”聲。
（五）輪體偏心偏重對噪聲的影響。
輪體偏心偏重的齒輪在嚙合運轉時產生不平衡的離心力，它是一種交變應力，會引起輪系的振動而產生噪聲，因此對輪體進行動態平衡檢測是必要的環節。
二、減速器箱體孔加工精度對噪聲的影響? 
    箱體孔的加工精度對減速器的噪聲有著突出的影響。孔的精度是指孔徑的精度，中心矩的誤差，各孔中心線的平行度與傾斜度。生產實踐中我們體會到軸承外圈與減速器箱體孔的配合間隙影響著軸承噪聲，當孔與軸承外圈的間隙在0.01mm左右時，能夠降低軸承對整機的噪音影響。
三、裝配精度對噪聲的影響
    裝配質量對減速器噪聲控制有著直接的影響。因此在整機裝配中應注意：
①各級齒輪傳動正常，保證嚙合側隙，齒面嚙合良好，注意定為零件（如軸套）的固定，避免齒輪端面的振擺等。
②安裝軸承時要避免施加不當的敲擊，在軸承運輸、裝配過程中避免碰撞等。
③按要求對減速器傳動部件的清洗，避免在裝配過程中對傳動部件的磕碰。
