減速機(jī)技術(shù)資料：
減速機(jī)是工業(yè)企業(yè)大量應(yīng)用的設(shè)備，一旦漏油，不僅造成經(jīng)濟(jì)損失，嚴(yán)重時(shí)還會(huì)引起減速機(jī)少油、斷油，使齒輪嚙合面磨損加劇，進(jìn)而發(fā)生打齒或剝離，導(dǎo)致設(shè)備事故。減速機(jī)漏油，對(duì)周圍環(huán)境污染厲害，對(duì)基礎(chǔ)有腐蝕作用，這樣既破壞了文明生產(chǎn)又浪費(fèi)了不少本可回收再生的潤(rùn)滑油。減速機(jī)漏油，是減速機(jī)使用中常見的故障現(xiàn)象。正確分析和診斷減速機(jī)漏油的原因，并針對(duì)原因采取有效解決方法，是保證減速機(jī)正常運(yùn)行、延長(zhǎng)減速機(jī)使用壽命的關(guān)鍵。
減速機(jī)漏油的原因分析
通常情況下，造成減速機(jī)漏油主要有5個(gè)方面的原因：
1.減速機(jī)內(nèi)外產(chǎn)生的壓力差
在封閉的減速機(jī)里，每一對(duì)齒輪相嚙合發(fā)生摩擦便要發(fā)出熱量，根據(jù)波義耳—馬略特定律，隨著運(yùn)轉(zhuǎn)時(shí)間的加長(zhǎng)，減速機(jī)箱內(nèi)溫度逐漸升高，而減速機(jī)箱內(nèi)體積不變，故箱體內(nèi)壓力隨之增加，箱體內(nèi)潤(rùn)滑油經(jīng)飛濺，灑在減速機(jī)箱內(nèi)壁。潤(rùn)滑油在壓差作用下，從縫隙處漏出。
2.減速機(jī)結(jié)構(gòu)設(shè)計(jì)不合理或加工存在問題
設(shè)計(jì)的減速機(jī)沒有通風(fēng)罩或窺視孔蓋上無(wú)透氣塞；軸封結(jié)構(gòu)設(shè)計(jì)不合理，采用油溝、氈圈式軸封結(jié)構(gòu)，由于毛氈的補(bǔ)償性能極差，導(dǎo)致密封在短時(shí)間內(nèi)即失效；油溝上雖有回油孔，但極易堵塞，回油作用難以發(fā)揮。制造過(guò)程中，鑄件未進(jìn)行退火或時(shí)效處理，鑄件未消除內(nèi)應(yīng)力，導(dǎo)致變形產(chǎn)生間隙從而發(fā)生漏油現(xiàn)象；存在砂眼、夾渣、氣孔、裂紋等缺陷；加工精度不良引起的漏油，由于減速機(jī)箱體配合面加工精度不高、公差不合適、裝配不符合要求等因素的存在,導(dǎo)致減速機(jī)可能漏油。
3.加油量過(guò)多
減速機(jī)在運(yùn)轉(zhuǎn)過(guò)程中，油池被攪動(dòng)得很厲害，潤(rùn)滑油在機(jī)內(nèi)到處飛濺，如果加油量過(guò)多，使大量潤(rùn)滑油積聚在軸封、結(jié)合面等處，導(dǎo)致泄漏。
4.安裝和檢修工藝不當(dāng)
安裝精度不高引起的漏油。減速機(jī)在啟動(dòng)時(shí)承受巨大的動(dòng)載荷,一旦減速機(jī)的安裝精度達(dá)不到標(biāo)準(zhǔn)要求,將導(dǎo)致減速機(jī)底座螺栓松動(dòng),從而加劇減速機(jī)的振動(dòng),使減速機(jī)高、低速軸孔處的密封圈磨損加劇,使?jié)櫥土鞒觥Ｍ瑫r(shí)設(shè)備檢修時(shí)，由于結(jié)合面上污物清除不徹底，或密封膠選用不當(dāng)、密封件方向裝反、不及時(shí)更換密封件等，也會(huì)引起漏油。
5.油品選擇不當(dāng)
一般減速機(jī)常采用HJ-40、HJ-50號(hào)機(jī)械潤(rùn)滑油，也可采用HL-30、HL-20齒輪油及HJ3-28軋鋼機(jī)油等潤(rùn)滑。總之，應(yīng)根據(jù)負(fù)荷、轉(zhuǎn)速、溫度等條件來(lái)選用減速機(jī)的潤(rùn)滑油，一味地追求潤(rùn)滑油黏度越大越好是不對(duì)的。
