斜齒輪減速機常見問題及其原因
1.減速機發(fā)熱和漏油
為了提率，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Ra0.8μm。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(yīng)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，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)。

IKO軸承溫度升高的原因：軸承冷卻水中斷。油質(zhì)劣化，油自身不清潔或運行中油劣化，如油中的水分增加會引起油的酸性增大，會降低油的潤滑作用，使軸瓦遭到腐蝕，造成軸承溫度升高?，F(xiàn)象：有警報電鈴響.機旁盤水輪機械故障光字牌亮，指示IKO軸承溫度的儀表溫度升高，信號繼電器動作。溫度計盤（膨脹型溫度計）黑針與黃針重合或超過黃針。發(fā)出軸承溫度升高的故障信號。處理當IKO軸承溫度升高時，首先判斷是否誤動作，如確實升高，應(yīng)做如下處理：檢查冷卻水水壓，水流及管路系統(tǒng)是否正常。
與簡單的圓柱齒輪減速機相比，行星減速機的功率密度極高。通過將扭矩分配到旋轉(zhuǎn)的圓柱齒輪上，從而執(zhí)行多次齒嚙合，達到極高的功率密度。這樣可實現(xiàn)緊湊型結(jié)構(gòu)，確保超高的效率。此外，通過同一內(nèi)齒圓柱齒輪中簡單的串行排列即可實現(xiàn)多級傳動比。根據(jù)每個行星等級的單一傳動比可得出總傳動比。
轉(zhuǎn)速和扭矩的轉(zhuǎn)化類似于圓柱齒輪減速機。例如，傳動比為 10:1 時，如果扭矩增加 10，則轉(zhuǎn)速減少相應(yīng)系數(shù)。
同軸減速機的優(yōu)點：
輸入軸和輸出軸同軸
效率極高
功率密度極高
結(jié)構(gòu)緊湊
應(yīng)用范圍廣
可實現(xiàn)多級減速機，傳動比極高

不管怎么說，前些年吊頂?shù)钠占爸辽俅龠M了吊頂材料的不斷變化和革新。如今，早已由過去的石膏板發(fā)展到如今的PVC板、PS板、礦棉板、鋁天花等。吊頂知識入門系列材質(zhì)篇帶你科普石膏板：是過去常用的吊頂材料之一，質(zhì)輕價低，根據(jù)大小規(guī)格的不同，每平方米從十幾元到幾十元不等。用石膏板做吊頂需用龍骨安裝，另外，有的普通石膏用久了會發(fā)生粉化和下陷，所以現(xiàn)在市場上并不多見。PVC板：值得推薦的一種吊頂材料，價格從每平方米幾元到二十幾元。
