44、蝸桿減速機是一種動力傳達機構(gòu)，利用齒輪的速度轉(zhuǎn)換器，將電機（馬達）的回轉(zhuǎn)數(shù)減速到所要的回轉(zhuǎn)數(shù)，并得到較大轉(zhuǎn)矩的機構(gòu)。在目前用于傳遞動力與運動的機構(gòu)中，減速機的應用范圍相當廣泛，幾乎在各式機械的傳動系統(tǒng)中都可以見到它的蹤跡，從交通工具的船舶、汽車、機車，建筑用的重型機具，機械工業(yè)所用的加工機具及自動化生產(chǎn)設(shè)備，到日常生活中常見的家電，鐘表等等.其應用從大動力的傳輸工作，到小負荷，精確的角度傳輸都可以見到減速機的應用，且在工業(yè)應用上，減速機具有減速及增加轉(zhuǎn)矩功能。因此廣泛應用在速度與扭矩的轉(zhuǎn)換設(shè)備。減速機的作用主要有： 1） 降速同時提高輸出扭矩，扭矩輸出比例按電機輸出乘減速比，但要注意不能超

45、出減速機額定扭矩。 　　 2）減速同時降低了負載的慣量，慣量的減少為減速比的平方。大家可以看一下一般電機都有一個慣量數(shù)值。 蝸輪蝸桿減速機分類： 主要型號：WP系列蝸輪蝸桿減速機、WH系列蝸輪蝸桿減速機和CW系列蝸輪蝸桿減速機等。 　　 1. WP系列蝸輪蝸桿減速機包括WPA/WPS/WPW/WPE/WPZ/WPD 2. WH系列蝸輪蝸桿減速機包括WHT/WHX/WHS/WHC 3. CW系列蝸輪蝸桿減速機包括CWU/CWS/CWO 　 4. RV系列蝸輪蝸桿減速機包括RV/NMRV/NRV 蝸輪蝸桿減速機的常見問題及分析： 1． 減速機發(fā)熱和漏油。 2． 蝸輪磨損。

46、 3． 傳動小斜齒輪磨損。 4． 蝸桿軸承損壞。 1． 減速機發(fā)熱和漏油 為了提高效率，蝸輪減速機一般均采用有色金屬做蝸輪，蝸桿則采用較硬的鋼材。由于是滑動摩擦傳動，運行中會產(chǎn)生較多的熱量，使減速機各零件和密封之間熱膨脹產(chǎn)生差異，從而在各配合面形成間隙，潤滑油液由于溫度的升高變稀，易造成泄漏。造成這種情況的原因主要有四點，一是材質(zhì)的搭配不合理；二是嚙合摩擦面表面的質(zhì)量差；三是潤滑油添加量的選擇不正確；四是裝配質(zhì)量和使用環(huán)境差。 　　 2． 蝸輪磨損 蝸輪一般采用錫青銅，配對的蝸桿材料用45鋼淬硬至HRC4555，或40Cr淬硬HRC5055后經(jīng)蝸桿磨床磨削至粗糙度Ra0.

47、8μm。減速機正常運行時磨損很慢，某些減速機可以使用10年以上。如果磨損速度較快，就要考慮選型是否正確，是否超負荷運行，以及蝸輪蝸桿的材質(zhì)、裝配質(zhì)量或使用環(huán)境等原因。 　　 3． 傳動小斜齒輪磨損 一般發(fā)生在立式安裝的減速機上，主要與潤滑油的添加量和油品種有關(guān)。立式安裝時，很容易造成潤滑油量不足，減速機停止運轉(zhuǎn)時，電機和減速機間傳動齒輪油流失，齒輪得不到應有的潤滑保護。減速機啟動時，齒輪由于得不到有效潤滑導致機械磨損甚至損壞。 　　 4． 蝸桿軸承損壞 發(fā)生故障時，即使減速箱密封良好，還是經(jīng)常發(fā)現(xiàn)減速機內(nèi)的齒輪油被乳化，軸承生銹、腐蝕、損壞。這是因為減速機在運行一段時間后，

48、齒輪油溫度升高又冷卻后產(chǎn)生的凝結(jié)水與水混合。當然，也與軸承質(zhì)量及裝配工藝密切相關(guān)。 解決方法： 1．保證裝配質(zhì)量?？少徺I或自制一些專用工具，拆卸和安裝減速機部件時，盡量避免用錘子等其他工具敲擊；更換齒輪、蝸輪蝸桿時，盡量選用原廠配件和成對更換；裝配輸出軸時，要注意公差配合；要使用防粘劑或紅丹油保護空心軸，防止磨損生銹或配合面積垢，維修時難拆卸。 　 2．潤滑油和添加劑的選用。蝸齒減速機一般選用220#齒輪油，對重負荷、啟動頻繁、使用環(huán)境較差的減速機，可選用一些潤滑油添加劑，使減速機在停止運轉(zhuǎn)時齒輪油依然附著在齒輪表面，形成保護膜，防止重負荷、低速、高轉(zhuǎn)矩和啟動時金屬間的直接接觸。添加劑

49、中含有密封圈調(diào)節(jié)劑和抗漏劑，使密封圈保持柔軟和彈性，有效減少潤滑油漏。 　　 3．減速機安裝位置的選擇。位置允許的情況下，盡量不采用立式安裝。立式安裝時，潤滑油的添加量要比水平安裝多很多，易造成減速機發(fā)熱和漏油。 　 4．建立潤滑維護制度。可根據(jù)潤滑工作“五定”原則對減速機進行維護，做到每一臺減速機都有責任人定期檢查，發(fā)現(xiàn)升溫明顯，超過40℃或油溫超過80℃，油的質(zhì)量下降或油中發(fā)現(xiàn)較多的銅粉以及產(chǎn)生不正常的噪聲等現(xiàn)象時，要立即停止使用，及時檢修，排除故障，更換潤滑油。加油時，要注意油量，保證減速機得到正確的潤滑。 蝸輪蝸桿減速機國家標準： TP型平面包絡環(huán)面蝸輪減速機（JB/T905

51、390-86） 蝸輪蝸桿減速機常見問題原因分析：齒輪-蝸輪蝸桿減速機是一種結(jié)構(gòu)緊湊、傳動比大，在一定條件下具有自鎖功能的傳動機械。而且安裝方便、結(jié)構(gòu)合理，得到越來越廣泛的應用。它是在蝸輪蝸桿減速器輸入端加裝一個斜齒輪減速器，構(gòu)成的多級減速器可獲得非常低的輸出速度，比單級蝸輪減速機具有更高的效率，而且振動小、噪聲及能低。 蝸輪蝸桿減速機最新維修方法： 針對磨損問題，企業(yè)傳統(tǒng)解決辦法是補焊或刷鍍后機加工修復，但兩者均存在一定弊端：補焊高溫產(chǎn)生的熱應力無法完全消除，易造成材質(zhì)損傷，導致部件出現(xiàn)彎曲或斷裂；而電刷鍍受涂層厚度限制，容易剝落，且以上兩種方法都是用金屬修復金屬，無法改變“

52、硬對硬”的配合關(guān)系，在各力綜合作用下，仍會造成再次磨損。對一些大的軸承企業(yè)往往無法現(xiàn)場解決，還要依賴外協(xié)修復。當代西方國家針對以上問題多采用高分子復合材料的修復方法，而應用較多的有美嘉華技術(shù)產(chǎn)品，其具有超強的粘著力，優(yōu)異的抗壓強度等綜合性能。應用高分子材料修復，可免拆卸免機加工既無補焊熱應力影響，修復厚度也不受限制，同時產(chǎn)品所具有的金屬材料不具備的退讓性，可吸收設(shè)備的沖擊震動，避免再次磨損的可能，并大大延長設(shè)備部件的使用壽命，為企業(yè)節(jié)省大量的停機時間，創(chuàng)造巨大的經(jīng)濟價值。 而針對滲漏問題，傳統(tǒng)方法需要拆卸并打開減速機后，更換密封墊片或涂抹密封膠，不僅費時費力，而且難以確保密封效果，在運行中還會

53、再次出現(xiàn)泄漏。高分子材料可現(xiàn)場治理滲漏，材料具備的優(yōu)越的粘著力、耐油性及350%的拉伸度，克服減速機振動造成的影響，很好地為企業(yè)解決了減速機滲漏問題。 安裝注意事項： 在安裝蝸輪蝸桿減速機時必須牢固的安裝在機器上，不能出現(xiàn)松動的現(xiàn)象。在此過程中必須要確認減速機的轉(zhuǎn)向是否正確，然后方可斷續(xù)進行安裝操作。減速機不能放置太久，超過3～6個月時，而油封又沒有浸在潤滑油中的話，建議減速機用戶更換油封。請按照減速機使用守則，標準的工作環(huán)境的溫度是-5度到10度，如果超過這個額定數(shù)值時，請與東莞市臺機減速機有限公司技術(shù)部聯(lián)系。減速機通常與減速馬達或者電機配套使用，所以必須裝置通風裝置，提高散熱工作并保

54、持正常運轉(zhuǎn)。安裝好后使用時，必須先檢查潤滑油位，并不以馬上把負載提到最高，建議逐步增加，建議在蝸輪蝸桿減速機的周邊安裝保護裝置。 HW系列蝸輪蝸桿減速機 一、概述： HW型直廓環(huán)面蝸桿減速器(JB／T7936一1999)因所采用的環(huán)面蝸桿副，其蝸桿軸向截面齒廓為直線，故稱其為直廓環(huán)面蝸桿(亦稱球面蝸桿)，與其他各種蝸桿減速器相同，為空間交錯軸傳動，承載能力和傳動效率較高，適用于重載、大功率、大轉(zhuǎn)矩傳動，如冶金、礦山、起重、運輸、石油、化工、建筑等機械 設(shè)備的減速傳動。包括HWT、HWB型二種型式。 工作條件：輸入、輸出軸交錯角為90*，蝸桿轉(zhuǎn)速不超過1500r’／min，蝸桿

56、結(jié)構(gòu)，箱體外形美觀，以優(yōu)質(zhì)鋁合金壓鑄而成。RV系列蝸輪蝸桿減速機目前已廣泛應用于各類行業(yè)生產(chǎn)工藝裝備的機械減速裝置，是目前現(xiàn)代工業(yè)裝備實現(xiàn)大扭矩、大速比低噪音、高穩(wěn)定機械減速傳動控制裝置的最佳選擇。 2、 技術(shù)參數(shù) 功 率：0.06KW～7.5KW 轉(zhuǎn) 矩：2.6Nm～2379Nm 傳動比：7.5-100 三、特點 1、機械結(jié)構(gòu)緊湊、體積外形輕巧、小型高效； 　　 2、熱交換性能好、散熱快； 　　 3、安裝簡易、靈活輕捷、性能優(yōu)越、易于維護檢修； 　　 4、運行平穩(wěn)、噪音小、經(jīng)久耐用； 　　 5、使用性強、安全可靠性大 四、使用維護要求 1、安裝時請不要對減速機輸出部件，箱體施加壓力，聯(lián)接時請滿足機械與減速機之間的同軸度與垂直度的相應要求 ?！　? 2、 減速機初始運行至400小時應重新更換潤滑油，其后的換油周期約為4000小時。 3、減速機箱體內(nèi)應保留足夠的潤滑油量，并定時檢查。 4、注意保持減速機外觀清潔，及時清除灰塵、污物以利于散熱。
