蝸輪減速機常見問題分析
蝸輪蝸桿減速機作為一個傳統的傳動裝置，內部是渦輪蝸桿，齒形是漸開線的。很多的蝸輪減速機使用者對蝸輪減速機的了解情況是少之又少的，更不要說對于一些常見問題的分析了，下面我們就和大家一起來了解下蝸輪減速機常見問題分析。
一、常見問題及其原因
1．減速機發熱和漏油。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，運行中會產生較多的熱量，使減速機各零件和密封之間熱膨脹產生差異，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，一是材質的搭配不合理；二是嚙合摩擦面表面的質量差；三是潤滑油添加量的選擇不正確；四是裝配質量和使用環境差。
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后經蝸桿磨床磨削至粗糙度Ra0.8μm。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、裝配質量或使用環境等原因。
3．傳動小斜齒輪磨損。一般發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。立式安裝時，很容易造成潤滑油量不足，減速機停止運轉時，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。發生故障時，即使減速箱密封良好，還是經常發現減速機內的齒輪油被乳化，軸承生銹、腐蝕、損壞。這是因為減速機在運行一段時間后，齒輪油溫度升高又冷卻后產生的凝結水與水混合。當然，也與軸承質量及裝配工藝密切相關。
二、解決方法
1．保證裝配質量。可購買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、高轉矩和啟動時金屬間的直接接觸。添加劑中含有密封圈調節劑和抗漏劑，使密封圈保持柔軟和彈性，有效減少潤滑油泄漏。
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，易造成減速機發熱和漏油。
4．建立潤滑維護制度。可根據潤滑工作“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，發現溫升明顯，超過40℃或油溫超過80℃，油的質量下降或油中發現較多的銅粉以及產生不正常的噪聲等現象時，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。還可以選用齒輪箱清洗維護機利用齒輪箱原有的給排油系統以及過濾后的潤滑油對齒輪箱進行清洗，不改變齒輪箱任何硬件設施、不添加任何清洗劑，保證了齒輪箱安全運營，延長了齒輪箱的使用壽命。
