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、箱體的作用二引起的發生振動。評定圓柱齒輪減速器質量
水平的主要標準就是它的的噪音值。隨著產品標準的國際化，國家對減速器的噪音值做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。
減速器中齒輪加工對減速機噪音的影響
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機噪聲的根本。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：盡量提高齒輪的彎曲強度，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音值。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。具有較高的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。
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機的噪音有著突出的影響。空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德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。
裝配精度也對噪聲的影響
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（如軸承）的固定，避免齒輪端面的振擺等。
2、安裝軸承是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。
