減速機技術資料：

蝸輪蝸桿減速機的常見問題及分析
常見問題及其原因。
(1)減速機發熱和漏油，
(2)蝸輪磨損，
(3)傳動小斜齒輪磨損，
(4)軸承(蝸桿處)損壞。
1、減速機發熱和漏油
蝸輪減速機為了提高效率，一般均采用有色金屬做蝸輪，采用較硬的鋼材做蝸桿，由于它是滑動摩擦傳動，在運行過程中，就會產生較高的熱量，使減速機各零件和密封之間熱膨脹產生差異，從而在各配合面產生間隙，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，一是材質的搭配是否合理，二是嚙合磨擦面的表面質量，三是潤滑油的選擇，添加量是否正確，四是裝配質量和使用環境。
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，經蝸桿磨床磨削至粗糙度RaO.8fcm,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，使蝸輪產生磨損。一般來說，這種磨損很慢，象某廠有些減速機可以使用10年以上。如果磨損速度較快，就要考慮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，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，主要跟潤滑油的添加量和潤滑油的選擇有關。立式安裝時，很容易造成潤滑油油量不足，當減速機停止運轉時，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，啟動或運轉過程中得不到有效的潤滑導致機械磨損甚至損壞。
4、蝸桿軸承損壞
減速機發生故障時，即使減速箱密封良好，該廠還是經常發現減速機內的齒輪油已經被乳化，軸承已生銹、腐蝕、損壞，這是因為減速機在運停過程中，齒輪油由熱變冷后產生的水分凝聚造成;當然，也和軸承質量，裝配工藝方法密切相關。
