style="text-indent:25px">滾動(dòng)軸承允許轉(zhuǎn)速：因軸承的類型不同有很大的差異。一般情況下，摩擦小、發(fā)熱量少的軸承，適于高轉(zhuǎn)速。設(shè)計(jì)時(shí)應(yīng)力求滾動(dòng)軸承在低于其極限轉(zhuǎn)速的條件下工作。剛性：軸承承受負(fù)荷時(shí)，軸承套圈和滾動(dòng)體接觸處就會(huì)產(chǎn)生彈性變形，變形量與載荷成比例，其比值決定軸承剛性的大小。一般可通過軸承的預(yù)緊來提高軸承的剛性；此外，在軸承支承設(shè)計(jì)中，考慮軸承的組合和排列方式也可改善軸承的支承剛度。調(diào)心性能和安裝誤差：軸承裝入工作位置后，往往由于制造誤差造成安裝和定位不良。此時(shí)常因軸產(chǎn)生撈度和熱膨脹等原因，使軸承承受過大的載荷，引起早期的損壞。自動(dòng)調(diào)心軸承可自行克服由安裝誤差引起的缺陷，因而是適合此類用途的軸承。安裝和拆卸：圓錐滾子軸承、滾針軸承等，屬于內(nèi)外圈可分離的軸承類型（即所謂分離型軸承），安裝拆卸方便。市場(chǎng)性：即使是列入產(chǎn)品目錄的軸承，市場(chǎng)上不一定有銷售；反之，未列入產(chǎn)品目錄的軸承有的卻大量生產(chǎn)。因而，應(yīng)清楚使用的軸承是否易購(gòu)得。</p><p
