style="text-indent:25px">直線導(dǎo)軌的額定壽命：所謂額定壽命是指一批相同的產(chǎn)品，在相同的條件及額定負(fù)荷下，有90%未曾發(fā)生表面剝離現(xiàn)象而達(dá)到的運(yùn)行距離。直線導(dǎo)軌副使用鋼珠作為滾動(dòng)體的額定壽命，在基本動(dòng)額定負(fù)荷下為50km?！? 直線導(dǎo)軌的基本靜額定負(fù)荷(Co)：所謂基本靜額定負(fù)荷是指在負(fù)荷方向和大小均等的狀態(tài)下，在受到應(yīng)力的接觸面處，鋼珠與滾道表面的總變形量恰為鋼珠直徑萬(wàn)分之一時(shí)的靜負(fù)荷，鹽城直線導(dǎo)軌副廠家直供，鹽城直線導(dǎo)軌副廠家直供，鹽城直線導(dǎo)軌副廠家直供。由于在機(jī)械加工方面的精度要求愈來(lái)愈高，使得對(duì)加工機(jī)械上的重要零組件直線導(dǎo)軌的精度等級(jí)劃分也越來(lái)越細(xì)。 5. 直線導(dǎo)軌基本動(dòng)額定負(fù)荷(C)：所謂基本動(dòng)額定負(fù)荷是指一批相同規(guī)格的直線導(dǎo)軌副，在負(fù)荷方向和大小均等的狀態(tài)下，經(jīng)過(guò)運(yùn)行50km后，90%的直線導(dǎo)軌其滾道表面不產(chǎn)生疲勞損壞(剝離或點(diǎn)蝕)時(shí)的負(fù)荷。</p><div

style="text-indent:25px">直線導(dǎo)軌的精度等級(jí)：一般直線導(dǎo)軌副的精度分為普通級(jí)、高級(jí)、精密級(jí)、超精密級(jí)和超高精密級(jí)五種。主要檢測(cè)指標(biāo)一般有三個(gè)，一是滑塊C面對(duì)滑軌A面的平行度，二是滑塊D面對(duì)滑軌B面的平行度，三是行走平行度，所謂行走平行度是指將直線導(dǎo)軌固定在基準(zhǔn)座平面上，使滑塊沿行程行走時(shí)，導(dǎo)軌與滑塊基準(zhǔn)面之間的平行度誤差?！? 直線導(dǎo)軌的預(yù)壓力：所謂預(yù)壓力是預(yù)先給予鋼珠負(fù)荷力，利用鋼珠與珠道之間負(fù)向間隙給予預(yù)壓，這樣能夠提高直線導(dǎo)軌的剛性和消除間隙?！?按照預(yù)壓力的大小可以分為不同的預(yù)壓等級(jí)。預(yù)壓力從有間隙到0.13C不等。C值為動(dòng)額定負(fù)荷。在選用的過(guò)程中可以根據(jù)計(jì)算結(jié)果隨時(shí)返回到前面的步驟進(jìn)行重新選擇和設(shè)定。計(jì)算滑塊負(fù)荷時(shí)要確認(rèn)選用的直線導(dǎo)軌靜安全系數(shù)應(yīng)該超過(guò)推薦表中所列值?！?如果所選用的直線導(dǎo)軌副剛性不足，可以提高預(yù)壓力，加大選用尺寸或增加滑塊數(shù)來(lái)提高剛性。靜安全系數(shù)定義為靜額定負(fù)荷與工作負(fù)荷的比值。值得提到的是兩列歌德式結(jié)構(gòu)的直線導(dǎo)軌副能承受各個(gè)方向的力和力矩，在輕負(fù)載或中負(fù)載應(yīng)用場(chǎng)合較多，尤其在側(cè)向力負(fù)載較大時(shí)。</p><div

a)定位精度高。滾動(dòng)直線導(dǎo)軌的運(yùn)動(dòng)借助鋼球滾動(dòng)實(shí)現(xiàn)，導(dǎo)軌副摩擦阻力小，動(dòng)靜摩擦阻力差值小，低速時(shí)不易產(chǎn)生爬行。重復(fù)定位精度高，適合作頻繁啟動(dòng)或換向的運(yùn)動(dòng)部件?？蓪C(jī)床定位精度設(shè)定到超微米級(jí)。同時(shí)根據(jù)需要，適當(dāng)增加預(yù)載荷，確保鋼球不發(fā)生滑動(dòng)，實(shí)現(xiàn)平穩(wěn)運(yùn)動(dòng)，減小了運(yùn)動(dòng)的沖擊和振動(dòng)。 b)磨損小。對(duì)于滑動(dòng)導(dǎo)軌面的流體潤(rùn)滑，由于油膜的浮動(dòng)，產(chǎn)生的運(yùn)動(dòng)精度誤差是無(wú)法避免的。在絕大多數(shù)情況***體潤(rùn)滑只限于邊界區(qū)域，由金屬接觸而產(chǎn)生的直接摩擦是無(wú)法避免的，在這種摩擦中，大量的能量以摩擦損耗被浪費(fèi)掉了。與之相反，滾動(dòng)接觸由于摩擦耗能小，滾動(dòng)面的摩擦損耗也相應(yīng)減少，故能使?jié)L動(dòng)直線導(dǎo)軌系統(tǒng)長(zhǎng)期處于高精度狀態(tài)。同時(shí)，由于使用潤(rùn)滑油也很少，這使得在機(jī)床的潤(rùn)滑系統(tǒng)設(shè)計(jì)及使用維護(hù)方面都變的非常容易。
