減速機(jī)斷軸原因排查
皮帶輸送機(jī)減速機(jī)斷軸發(fā)生在減速機(jī)高速軸上。常見(jiàn)的是采用的減速機(jī)級(jí)為垂直傘齒輪軸的高速軸。發(fā)生斷軸主要有：
1．減速機(jī)高速軸設(shè)計(jì)上強(qiáng)度不夠
這種情況一般發(fā)生在軸肩處，由于此處有過(guò)渡圓角，極易發(fā)生疲勞損壞，如圓角過(guò)小會(huì)使減速機(jī)在較短的時(shí)間內(nèi)斷軸。斷軸后的斷口通常比較平齊。發(fā)生這種情況應(yīng)當(dāng)更換減速機(jī)或修改減速機(jī)的設(shè)計(jì)。
2．高速軸不同心

臨近三月的傳統(tǒng)旺季，鋼材市場(chǎng)的需求啟動(dòng)仍然表現(xiàn)低下，盡管近兩天鋼價(jià)有回升增長(zhǎng)態(tài)勢(shì)，但整體而言，疲弱的需求、以及高企的庫(kù)存數(shù)據(jù)讓業(yè)內(nèi)實(shí)在難言樂(lè)觀。截止212年2月17日，全國(guó)主要城市螺紋鋼庫(kù)存為849.51萬(wàn)噸，環(huán)比上一周增加38.87萬(wàn)噸，增幅為4.79%;線材庫(kù)存為25.35萬(wàn)噸，環(huán)比上一周增加9.95萬(wàn)噸，增幅為4.14%，雖然國(guó)內(nèi)線螺總庫(kù)存仍處于上行通道，但不難看出，年后庫(kù)存周環(huán)比增幅不斷降低，表明目前市場(chǎng)正處于緩慢的去庫(kù)存狀態(tài)。
6、硬是要將將交流電機(jī)3-2變換成直流電機(jī)的勵(lì)磁電流與轉(zhuǎn)矩電流分別控制的矢量控制是無(wú)知的“巫術(shù)”！
7、直流電機(jī)調(diào)速、交流電機(jī)調(diào)速，只是改變直流電機(jī)的電源的電壓、交流電機(jī)的交流電源的頻率及電壓；
8、作為電源，不存在控制電動(dòng)機(jī)的轉(zhuǎn)矩、轉(zhuǎn)矩電流的問(wèn)題，要通過(guò)電源控制電機(jī)的轉(zhuǎn)矩、轉(zhuǎn)矩電流的說(shuō)法本來(lái)就是無(wú)知的說(shuō)法；
9、電機(jī)的轉(zhuǎn)矩、轉(zhuǎn)矩電流是電機(jī)拖動(dòng)不同負(fù)載時(shí)自身原理決定的，例如電勢(shì)平衡原理、磁勢(shì)平衡原理、轉(zhuǎn)矩平衡原理決定的！
10、離開(kāi)負(fù)載，人為的控制電機(jī)轉(zhuǎn)矩、轉(zhuǎn)矩電流的說(shuō)法是“巫術(shù)”！負(fù)載的電流決定于負(fù)載，不是電源控制的，這是個(gè)常識(shí)問(wèn)題！
11、不論是矢量控制還是直接轉(zhuǎn)矩控制，都是本末倒置的說(shuō)法，都是“巫術(shù)”，不論是直流電機(jī)還是交流電機(jī)，轉(zhuǎn)矩是電機(jī)自身原理產(chǎn)生的，工作電流大小與負(fù)載輕重有關(guān)，絕不是人為控制的結(jié)果！

NSK軸承所要求的條件，性能也日趨多元化。才能從大量的結(jié)構(gòu)，大小，使用滾動(dòng)軸承的各種機(jī)械裝置，設(shè)備和日益嚴(yán)格的市場(chǎng)要求的其他屬性。選擇合適的NSK軸承，需要不同的角度。選擇NSK軸承時(shí)，一般認(rèn)為NSK軸承軸安排，安裝，裝配難度，NSK軸承允許的空間，市場(chǎng)規(guī)模和軸承等，在很大程度上決定了軸承結(jié)構(gòu)。其次，同時(shí)使用各種機(jī)械的設(shè)計(jì)壽命和各種耐久性限制NSK軸承NSK軸承的比較研究，同時(shí)決定軸承尺寸。選擇進(jìn)口軸承，NSK，NSK的往往是傾向于考慮軸承的疲勞壽命，在衰老發(fā)生的潤(rùn)滑脂壽命潤(rùn)滑脂，耐磨損，噪音，也需要充分研究。
