減速機(jī)技術(shù)資料：

減速器的噪聲是由于在它運(yùn)轉(zhuǎn)過程中機(jī)內(nèi)齒輪嚙合產(chǎn)生周期性的交變力對軸承、箱體的作用二引起的發(fā)生振動(dòng)。評(píng)定圓柱齒輪減速器質(zhì)量
水平的主要標(biāo)準(zhǔn)就是它的的噪音值。隨著產(chǎn)品標(biāo)準(zhǔn)的國際化，國家對減速器的噪音值做出了更加嚴(yán)格的限定，這就要求對減速器的噪聲控制進(jìn)行研究。
減速器中齒輪加工對減速機(jī)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(jī)噪聲的根本。為了降低齒輪噪聲，需從結(jié)構(gòu)設(shè)計(jì)與齒輪精度兩方面來考慮。
1、低噪聲齒輪結(jié)構(gòu)設(shè)計(jì)的要求。齒輪結(jié)構(gòu)設(shè)計(jì)對噪聲的影響是很重要的，理想的設(shè)計(jì)是：盡量提高齒輪的彎曲強(qiáng)度，選擇較大的變位系數(shù)與適當(dāng)?shù)穆菪�角，使嚙合系�?shù)加大，從而達(dá)到降低噪音的目的。
2、齒輪制造精度對噪聲的影響。對標(biāo)準(zhǔn)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(zhuǎn)速和扭矩，因此對它的齒輪制造精度要求，其工作平穩(wěn)性等級(jí)是主要的。具有較高的工作平穩(wěn)性等級(jí)的齒輪不僅本身的使用壽命長，而且傳動(dòng)中的沖擊、振動(dòng)小，噪聲也就小，所以限制齒輪的工作平穩(wěn)性誤差是減少齒輪噪聲的關(guān)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(jī)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(chǎn)實(shí)踐中我們體會(huì)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(dāng)孔與軸承外圈的間隙在0.01mm左右時(shí)，能夠降低軸承對整機(jī)的噪音影響。
裝配精度也對噪聲的影響
裝配質(zhì)量對減速器噪聲控制有著直接的影響。因此在整機(jī)裝配中應(yīng)注意：
1、各級(jí)齒輪傳動(dòng)正常，保證嚙合側(cè)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(dāng)?shù)那脫簦�在軸承運(yùn)輸、裝配過程中避免碰撞等。
3、按要求對減速器傳動(dòng)部件的清洗，避免在裝配過程中對傳動(dòng)部件的磕碰。
