style="text-indent:25px">在許多工業(yè)產(chǎn)品中，污染是不可避免的，因此常用密封或遮護(hù)裝置來保護(hù)微型軸承，使其免受灰塵或臟物的侵蝕。但是，由于微型軸承內(nèi)外圈的運(yùn)動(dòng)，使微型軸承的密封不可能達(dá)到完美的程度，因此潤滑油脂的泄漏和污染始終是一個(gè)讓人煩惱的問題。一旦微型軸承受到污染，潤滑油脂就要變質(zhì)，運(yùn)行噪聲也隨之變大。如果微型軸承過熱，它將會(huì)卡住。當(dāng)污染物處于滾珠和微型軸承圈之間時(shí)，其作用和金屬表面之間的磨粒一樣，會(huì)使微型軸承磨損。微型軸承扭矩要求是由潤滑油脂、保持架、微型軸承圈質(zhì)量以及是否使用密封或遮護(hù)裝置來決定。</p><p style="text-indent:25px">油品的熱安定性主要取決于基礎(chǔ)油的組成，很多分解溫度較低的添加劑往往對油品安定性有不利影響;抗氧劑也不能明顯地改善油品的熱安定性。油性和極壓性：油性是潤滑油中的極性物在摩擦部位金屬表面上形成堅(jiān)固的理化吸附膜，從而起到耐高負(fù)荷和抗摩擦磨損的作用，而極壓性則是潤滑油的極性物在摩擦部位金屬表面上，受高溫、高負(fù)荷發(fā)生摩擦化學(xué)作用分解，并和表面金屬發(fā)生摩擦化學(xué)反應(yīng)，形成低熔點(diǎn)的軟質(zhì)(或稱具可塑性的)極壓膜，從而起到耐沖擊、耐高負(fù)荷高溫的潤滑作用。潤滑脂大多是半固體狀的物質(zhì)，具有獨(dú)特的流動(dòng)性。</p><div
