減速機技術資料：

減速機是一種動力傳達機構，利用齒輪的速度轉換器，將電機(馬達)的回轉數減速到所要的回轉數，并得到較大轉矩的機構。在目前用于傳遞動力與運動的機構中，減速機的應用范圍相當廣泛。下面讓萬貫五金機電網的小編帶您一起了解一下蝸輪蝸桿減速機常見問題及其原因：
(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，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。
