減速齒輪箱選型和減少減速齒輪箱的噪音問題
一般來說，使用減速齒輪箱之前和使用過程中都會由于一些原因引起齒輪箱的噪音。那么降低減速齒輪箱噪音的方法有哪些呢？
降低減速齒輪箱噪音的方法：
1、提高齒輪的精度、選擇合適的齒輪參數(shù)；
2、對裝配工人進行培訓，提高工人的裝配水平，減少齒輪的安裝誤差；
3、調(diào)整電機聯(lián)軸器和齒輪箱聯(lián)軸器的同心度；
4、加固機架平臺，減少共振；
5、改善齒輪的潤滑情況，減少齒輪和軸承間的磨損以及齒輪與齒輪之間的嚙合間隙；
6、提高齒輪軸的剛度。

下面是SKF軸承裝配的一些相關(guān)事項。外圈的裝配事先在外殼的圓周上設(shè)置幾處外圈擠壓螺桿用螺絲，裝配過盈配合的外圈。一面均等地擰緊螺桿，一邊裝配。這些螺桿孔平常蓋上盲塞，SKF軸承等的分離型軸承，外殼擋肩上設(shè)置幾處切口，使用墊塊，用壓力機拆卸，或輕輕敲打著拆卸。圓柱孔軸承的裝配可以用壓力機械拔出簡單。此時，內(nèi)圈的裝配。要注意讓內(nèi)圈接受其拔力。以使易于拉拔。寬度大的軸承則油壓法與拉拔卡具并用，大型軸承的內(nèi)圈裝配采用油壓法。
中空軸式蝸齒行星減速機加裝一個斜齒輪減速器在輸入端，組成的減速器可獲得非常低的輸出速度，是斜齒輪級和蝸齒級的組合，比純單級蝸輪行星減速機具有更高的效率。而且振動小，噪音低，能耗低。
常見問題及其原因：(1)行星減速機發(fā)熱和漏油，(2)蝸輪磨損，(3)傳動小斜齒輪磨損，(4)軸承(蝸桿處)損壞。
1 行星減速機發(fā)熱和漏油。蝸輪行星減速機為了提率，一般均采用有色金屬做蝸輪，蝸桿則采用較硬的鋼材，由于它是滑動磨擦傳動，在運行過程中，就會產(chǎn)生較高的熱量，使行星減速機各零件和密封之間熱膨脹產(chǎn)生差異，從而在各配合面產(chǎn)生間隙，而油液由于溫度的升高變稀，容易造成泄漏。主要原因有四點，一是材質(zhì)的搭配是否合理，二是嚙合磨擦面的表面質(zhì)量，三是潤滑油的選擇，添加量是否正確，四是裝配質(zhì)量和使用環(huán)境。
2 蝸輪磨損。蝸輪一般采用錫青銅，配對的蝸桿材料一般用45鋼淬硬至HRC45一55,還常用40C:淬硬HRC50一55，經(jīng)蝸桿磨床磨削至粗糙度RaO. 8 fcm,行星減速機正常運行時，蝸桿就象一把淬硬的“銼刀”，不停地銼削蝸輪，使蝸輪產(chǎn)生磨損。一般來說，這種磨損很慢，象某廠有些行星減速機可以使用10年以上。如果磨損速度較快，就要考慮行星減速機的選型是否正確，是否有超負荷運行，蝸輪蝸桿的材質(zhì)，裝配質(zhì)量或使用環(huán)境等原因。

SKF進口軸承配合的作用是使得SKF進口軸承的靜止圈和旋轉(zhuǎn)圈分別與安裝部位的靜止部分(通常是軸承座)和旋轉(zhuǎn)部分(通常是軸)固結(jié)在一起，從而實現(xiàn)在旋轉(zhuǎn)狀態(tài)下傳遞載荷和限定運動系統(tǒng)相對于靜止系統(tǒng)位置的基本任務(wù)。在軸上和軸承座中，SKF進口軸承要求在徑向、軸向和切線方向等三個方向固定其位置。徑向和切向的定位通過對SKF進口軸承套圈的緊配合采實現(xiàn)，軸向定位只有在少數(shù)情況下采用緊配合；一般采用軸向限位零件，諸如端蓋和擋圈等將軸向位置限定在游隙范圍內(nèi)。
