力士樂導軌滑塊R167189310導軌、直線軸作為設備的核心部件之一，它的功用是起導向和支承作用。為了保證機器有較高的加工

精度，要求其導軌、直線具有較高的導向精度和良好的運動平穩(wěn)性。設備在運行過程中，由于被加工

件在加工中會產生大量的腐蝕性粉塵和煙霧，基這些煙霧和粉塵長期大量沉積于導軌、直線軸表面，

對設備的加工精度有很大影響，并且會在導軌直線軸表面形成蝕點，縮短設備使用壽命。為了讓機器

正常穩(wěn)定工作，確保產品的加工質量，要認真做好導軌、直線軸的日常維護。 注意：清潔導軌請準

備——干棉布、潤滑油。雕刻機的導軌分為直線導軌、滾輪導軌。 直線導軌的清潔：首先把激光頭

移動到較右側(或左側)，找到直線導軌，用干棉布擦拭直到光亮無塵，再加上少許潤滑油(可采用縫

紉機油，切勿使用機油)，將激光頭左右慢慢推動幾次，讓潤滑油均勻分布即可。 滾輪導軌的清潔：

把橫梁移動到內側，打開機器兩側端蓋，找到導軌，用干棉布把兩側導軌與滾輪接觸的地方擦拭干凈

，再移動橫梁，把剩余地方清潔干凈。

力士樂導軌滑塊R167189310REXROTH力士樂導軌滑塊star導軌滑塊設計的基本要求

1.導向精度-REXROTH滑塊導軌的導向精度

導向精度是指運動構件沿導軌導面運動時其運動軌跡的準確程度。影響導向精度的主要因素有導

軌承導面的幾何精度、導軌的結構類型、導軌副的接觸精度、表面粗糙度、導軌和支承件的剛度、導

軌副的油膜厚度及油膜剛度，以及導軌和支承件的熱變形等。

直線運動導軌的幾何精度一般包括：垂直平面和水平平面內的直線度；兩條導軌面間的平行度。

導軌幾何精度可以用導軌全長上的誤差或單位長度上的誤差表示。

2.精度保持性-REXROTH滑塊導軌的精度保持性

精度保持性是指導軌工作過程中保持原有幾何精度的能力。導軌的精度保持性主要取決于導軌的

耐磨性較其尺寸穩(wěn)定性。耐磨性與導軌副的材料匹配、受力、加工精度、潤滑方式和防護裝置的性能

的因素有關，另外，導軌及其支承件內的殘余應力也會影響導軌的精度保持性。

3.STAR滑塊、導軌-運動靈敏度和定位精度

運動靈敏度是指運動構件能實現(xiàn)的較小行程；定位精度是指運動構件能按要求停止在指定位置的

能力。運動靈敏度和定位精度與導軌類型、摩擦特性、運動速度、傳動剛度、運動構件質量等因素有

關。

4.REXROTH滑塊、導軌-運動平穩(wěn)性

導軌運動平穩(wěn)性是指導軌在低速運動或微量移動時不出現(xiàn)爬行現(xiàn)象的性能。平穩(wěn)性與導軌的結構

、導軌副材料的匹配、潤滑狀況、潤滑劑性質及導軌運動之傳動系統(tǒng)的剛度等因素有關。

5.REXROTH滾珠絲桿，REXROTH螺母-抗振性與穩(wěn)定性

抗振性是指導軌副承受受迫振動和沖擊的能力，而穩(wěn)定性是指在給定的運轉條件下不出現(xiàn)自激振

動的性能。

6.STAR導軌的剛度，力士樂REXROTH導軌的鋼度

導軌抵抗受力變形的能力。變形將影響構件之間的相對位置和導向精度，這對于準確機械與儀器

尤為重要。導軌變形包括導軌本體變形導軌副接觸變形，兩者均應考慮。

7.REXROTH滾珠螺母結構工藝性，STAR滾珠螺母結構工藝性

結構工藝性是指導軌副（包括導軌副所在構件）加工的難易程度。在滿足設計要求的前提下，應

盡量做到制造和維修方便，成本低廉。詳情可與我司聯(lián)系azhunmi@126.com 我們將為您提供更多、更

優(yōu)質的服務

力士樂rexroth準確導軌的設計原則star星牌準確導軌的設計原則

對幾何精度、運動精度和定位精度要求都較高的準確導軌（如數(shù)控機床和測量機的導軌），在設

計時應遵循如下一些原則：

1.REXROTH滑塊，STAR滑軌誤差補償原則 滿足下列三項要求，以使導軌系統(tǒng)實現(xiàn)誤差相互補償：

（1）導軌間必須設置中間彈性環(huán)節(jié)，如滾動體塑料帶（片）或流體膜等。

（2）導軌間要有足夠的預緊力，以便補償接觸誤差。

（3）導軌的制造誤差應小于中間彈性體（元件）的變形量。詳情可與我司聯(lián)系azhunmi@126.com 

我們將為您提供更多、更優(yōu)質的服務

2.力士樂軸承，STAR滑塊精度互不干涉原則

制造和使用時導軌的各項精度互不影響才易得到較高的精度。如：矩形導軌的直線性與側面導軌

的直線性在制造時互不影響；平-V導軌組合導軌橫向尺寸的變化不會影響導軌的工作精度。

3.REXROTH滾珠絲桿，STAR滾珠絲桿動、靜摩擦因數(shù)接近原則

設計導軌副時應使導軌接觸面的動、靜摩擦因數(shù)盡量接近，以便獲得高的重復定位精度和低速平

穩(wěn)性，滾動導軌、鑲裝塑料板或帖塑料片的普通滑動導軌，摩擦因數(shù)小且靜、動摩擦因數(shù)接近。

4.REXROTH導軌副自動帖合原則

要使導軌精度高，必須使導軌副有自動帖合的特性。水平導軌可以靠運動構件的重量來帖合；其

他導軌必須附加彈簧力或者滾輪壓力使其帖合。

5.REXROTH滑塊全部接觸原則

固定導軌的長度必須保證動導軌在較大行程的兩個較限位置，與固定導軌全長接觸（不會超出固

定導軌），以保證在接觸過程中導軌副始終全部接觸。

6.STAR滑塊REXROTH滑塊補償力變形和熱變形原則

導軌及其支承件受力或溫度變化時，設計導軌及其支承件時，力求使其變形后成為要求的形狀。
