水泥回轉窯傳動裝置簡介

水泥回轉窯分主傳動(dong)和輔助傳動(dong)。

傳(chuan)(chuan)動(dong)裝置分主傳(chuan)(chuan)動(dong)和(he)輔(fu)助(zhu)傳(chuan)(chuan)動(dong)。主傳(chuan)(chuan)動(dong)系統包括(kuo)：主電(dian)動(dong)機、主減速器、、大齒圈(quan)。輔(fu)助(zhu)傳(chuan)(chuan)動(dong)由(you)輔(fu)助(zhu)電(dian)機、減速機等組成，主要在(zai)停窯(yao)(yao)(yao)狀態下慢轉(zhuan)(zhuan)窯(yao)(yao)(yao)體時使用(yong)(yong)，供修理和(he)冷窯(yao)(yao)(yao)翻(fan)轉(zhuan)(zhuan)使用(yong)(yong)。

回轉窯的(de)傳(chuan)動裝置的(de)作用就是(shi)使(shi)水泥按工藝操(cao)作所需要的(de)轉速(su)正常地回轉，而且可以根據需要在一定(ding)的(de)轉速(su)變化范(fan)圍內(nei)實行無級(ji)調速(su)。

傳(chuan)(chuan)(chuan)動裝置過去一般為機(ji)械傳(chuan)(chuan)(chuan)動，現在(zai)由于工業(ye)的發展，采用了很多(duo)的先進(jin)技術。液壓傳(chuan)(chuan)(chuan)動已使用在(zai)回轉窯這(zhe)種重型回轉機(ji)械上(shang)。因(yin)此回轉窯的傳(chuan)(chuan)(chuan)動裝置可分機(ji)械傳(chuan)(chuan)(chuan)動和液壓傳(chuan)(chuan)(chuan)動兩大類(lei)型。但是目前國內氧化鋁(lv)廠家全部使用的還是機(ji)械傳(chuan)(chuan)(chuan)動。

機械傳動是水泥回轉窯的(de)筒(tong)體(ti)上套(tao)有大齒圈(quan)(quan)，位置(zhi)大致在回轉窯(yao)的(de)中部。大齒圈(quan)(quan)是(shi)由坐落在傳(chuan)動(dong)(dong)(dong)(dong)裝置(zhi)土建基(ji)礎上的(de)小齒輪來(lai)帶動(dong)(dong)(dong)(dong)的(de)。機(ji)(ji)械(xie)傳(chuan)動(dong)(dong)(dong)(dong)的(de)一(yi)般通用結構(gou)形式是(shi)主(zhu)(zhu)傳(chuan)動(dong)(dong)(dong)(dong)電(dian)(dian)機(ji)(ji)驅動(dong)(dong)(dong)(dong)主(zhu)(zhu)減(jian)速(su)(su)(su)(su)(su)器再帶動(dong)(dong)(dong)(dong)一(yi)對(dui)開式齒輪經(jing)這樣多次變速(su)(su)(su)(su)(su)后(hou)，使和大齒圈(quan)(quan)嚙(nie)合的(de)小榻胯疆能按操(cao)作所需要的(de)轉速(su)(su)(su)(su)(su)轉動(dong)(dong)(dong)(dong)，這樣大齒圈(quan)(quan)帶動(dong)(dong)(dong)(dong)窯(yao)體(ti)轉動(dong)(dong)(dong)(dong)就能符臺(tai)工(gong)藝操(cao)作的(de)要求。主(zhu)(zhu)減(jian)速(su)(su)(su)(su)(su)器除低速(su)(su)(su)(su)(su)輸(shu)出(chu)軸外，高(gao)速(su)(su)(su)(su)(su)輸(shu)入軸的(de)兩端各與一(yi)個電(dian)(dian)機(ji)(ji)聯(lian)接(jie)。一(yi)個是(shi)主(zhu)(zhu)傳(chuan)動(dong)(dong)(dong)(dong)電(dian)(dian)機(ji)(ji)，一(yi)個是(shi)輔助傳(chuan)動(dong)(dong)(dong)(dong)電(dian)(dian)機(ji)(ji)。輔助傳(chuan)動(dong)(dong)(dong)(dong)電(dian)(dian)機(ji)(ji)經(jing)過一(yi)套(tao)減(jian)速(su)(su)(su)(su)(su)裝置(zhi)后(hou)與減(jian)速(su)(su)(su)(su)(su)器的(de)高(gao)速(su)(su)(su)(su)(su)輸(shu)入軸聯(lian)接(jie)：主(zhu)(zhu)傳(chuan)動(dong)(dong)(dong)(dong)電(dian)(dian)機(ji)(ji)和主(zhu)(zhu)減(jian)速(su)(su)(su)(su)(su)器采用聯(lian)軸器直聯(lian)。

輔(fu)助(zhu)傳(chuan)動(dong)(dong)(dong)的(de)作用是當(dang)主(zhu)(zhu)傳(chuan)動(dong)(dong)(dong)電(dian)機(ji)或主(zhu)(zhu)電(dian)源發生故障(zhang)時，水泥回轉(zhuan)(zhuan)窯(yao)依(yi)靠輔(fu)助(zhu)傳(chuan)動(dong)(dong)(dong)還能(neng)(neng)繼續轉(zhuan)(zhuan)窯(yao)，但回轉(zhuan)(zhuan)速度(du)很慢(man)。它(ta)能(neng)(neng)使(shi)窯(yao)定期轉(zhuan)(zhuan)動(dong)(dong)(dong)，以(yi)免窯(yao)體因上下有溫差而造(zao)成(cheng)彎曲，并確(que)保存(cun)砌(qi)磚(zhuan)(zhuan)和檢修對，使(shi)窯(yao)體能(neng)(neng)停留在某個(ge)指定位置(zhi)。輔(fu)助(zhu)傳(chuan)動(dong)(dong)(dong)的(de)原動(dong)(dong)(dong)機(ji)，多數為電(dian)動(dong)(dong)(dong)機(ji)，它(ta)與主(zhu)(zhu)電(dian)動(dong)(dong)(dong)機(ji)分別用不同的(de)電(dian)源供(gong)電(dian)。在輔(fu)助(zhu)電(dian)動(dong)(dong)(dong)機(ji)與主(zhu)(zhu)減(jian)(jian)速器(qi)之間設有輔(fu)助(zhu)減(jian)(jian)速器(qi)，以(yi)增大速比(bi)。輔(fu)助(zhu)電(dian)動(dong)(dong)(dong)機(ji)上應配有制(zhi)動(dong)(dong)(dong)器(qi)，防止窯(yao)體在電(dian)動(dong)(dong)(dong)機(ji)停轉(zhuan)(zhuan)后由于在物料(liao)、砌(qi)磚(zhuan)(zhuan)的(de)偏(pian)重作用下反(fan)(fan)轉(zhuan)(zhuan)。窯(yao)反(fan)(fan)轉(zhuan)(zhuan)速度(du)往往接近甚(shen)至超過(guo)正常轉(zhuan)(zhuan)速，此時若輔(fu)助(zhu)傳(chuan)動(dong)(dong)(dong)未(wei)脫開，減(jian)(jian)速器(qi)變成(cheng)了(le)增速器(qi)，會使(shi)輔(fu)助(zhu)減(jian)(jian)速器(qi)、電(dian)動(dong)(dong)(dong)機(ji)轉(zhuan)(zhuan)速過(guo)高，達到每分鐘(zhong)l-萬轉(zhuan)(zhuan)，以(yi)致發生危險。

因此，制(zhi)動(dong)(dong)器(qi)與輔助(zhu)電(dian)動(dong)(dong)機必須同時(shi)接通或(huo)斷(duan)電(dian)：制(zhi)動(dong)(dong)器(qi)可采用電(dian)磁鐵型或(huo)YWZ液(ye)壓推桿(gan)制(zhi)動(dong)(dong)器(qi)。 由于慢速(su)下托輪、擋輪及傳動(dong)(dong)部分(fen)軸(zhou)承(cheng)潤滑小良，所以(yi)長時(shi)間使用輔助(zhu)傳動(dong)(dong)是不(bu)適宜(yi)的(de)，一般連續運(yun)轉不(bu)宜(yi)超過15分(fen)鐘(zhong)。
