Guiding accuracy

以及滑軌和支承件的熱變形等。導(dǎo)向精度是指運(yùn)動(dòng)構(gòu)件沿導(dǎo)軌導(dǎo)面運(yùn)動(dòng)時(shí)其運(yùn)動(dòng)軌跡的準(zhǔn)確水平。影響導(dǎo)向精度的主要因素有導(dǎo)軌承導(dǎo)面的幾何精度導(dǎo)軌的結(jié)構(gòu)類型導(dǎo)軌副的接觸精度外表粗糙度導(dǎo)軌和支承件的剛度導(dǎo)軌副的油膜厚度及油膜剛度。直線運(yùn)動(dòng)導(dǎo)軌的幾何精度一般包括：垂直平面和水平平面內(nèi)的直線度；兩條導(dǎo)軌面間的平行度。導(dǎo)軌幾何精度可以用導(dǎo)軌全長(zhǎng)上的誤差或單位長(zhǎng)度上的誤差表示。

And the thermal deformation of the sliding rail and supporting components. Guidance accuracy refers to the accurate level of the motion trajectory of the moving component when it moves along the guide surface of the guide rail. The main factors affecting guidance accuracy include the geometric accuracy of the guide rail bearing surface, the structural type of the guide rail, the contact accuracy of the guide rail pair, the surface roughness of the guide rail and the stiffness of the support components, and the oil film thickness and stiffness of the guide rail pair. The geometric accuracy of linear motion guides generally includes: straightness in the vertical and horizontal planes; The parallelism between the two guide rail surfaces. The geometric accuracy of the guide rail can be expressed as the error in the total length of the guide rail or the error per unit length.

精度堅(jiān)持性

Accuracy persistence

另外，精度堅(jiān)持性是指滑軌工作過(guò)程中保持原有幾何精度的能力。導(dǎo)軌的精度堅(jiān)持性主要取決于導(dǎo)軌的耐磨性及尺寸穩(wěn)定性。耐磨性與導(dǎo)軌副的資料匹配受力加工精度潤(rùn)滑方式和防護(hù)裝置的性能的因素有關(guān)。導(dǎo)軌及其支承件內(nèi)的剩余應(yīng)力也會(huì)影響導(dǎo)軌的精度堅(jiān)持性。

In addition, accuracy persistence refers to the ability to maintain the original geometric accuracy during the operation of the sliding rail. The accuracy of the guide rail mainly depends on its wear resistance and dimensional stability. The wear resistance is related to factors such as the matching of the data of the guide rail pair, the precision of the force processing, the lubrication method, and the performance of the protective device. The residual stress inside the guide rail and its supporting components can also affect the accuracy of the guide rail.

運(yùn)動(dòng)平穩(wěn)性

Motion stability

導(dǎo)軌運(yùn)動(dòng)平穩(wěn)性是指導(dǎo)軌在低速運(yùn)動(dòng)或微量移動(dòng)時(shí)不出現(xiàn)爬行現(xiàn)象的性能。平穩(wěn)性與導(dǎo)軌的結(jié)構(gòu)導(dǎo)軌副材料的匹配潤(rùn)滑狀況潤(rùn)滑劑（作用：能減少或避免摩擦磨損）性質(zhì)及導(dǎo)軌運(yùn)動(dòng)之傳動(dòng)系統(tǒng)的剛度等因素有關(guān)。

The smoothness of guide rail movement refers to the performance of the guide rail that does not exhibit crawling during low speed or slight movement. The smoothness is related to factors such as the matching lubrication condition of the structure and material of the guide rail, the properties of the lubricant (which can reduce or avoid friction and wear), and the stiffness of the transmission system of the guide rail movement.

運(yùn)動(dòng)靈敏度和定位精度

Motion sensitivity and positioning accuracy

直線模組運(yùn)動(dòng)靈敏度是指運(yùn)動(dòng)構(gòu)件能實(shí)現(xiàn)的行程；定位精度是指運(yùn)動(dòng)構(gòu)件能按要求停止在指定位置的能力。運(yùn)動(dòng)靈敏度和定位精度與導(dǎo)軌類型摩擦特性運(yùn)動(dòng)速度傳動(dòng)剛度運(yùn)動(dòng)構(gòu)件質(zhì)量等因素有關(guān)。

Linear module motion sensitivity refers to the stroke that the moving component can achieve; Positioning accuracy refers to the ability of moving components to stop at designated positions as required. The motion sensitivity and positioning accuracy are related to factors such as the type of guide rail, friction characteristics, motion speed, transmission stiffness, and mass of motion components.

剛度

Stiffness

這對(duì)于精密機(jī)械與儀器尤為重要。直線導(dǎo)軌變形包括導(dǎo)軌本體變形導(dǎo)軌副接觸變形，導(dǎo)軌抵抗受力變形的能力。變形將影響構(gòu)件之間的相對(duì)位置和導(dǎo)向精度。兩者均應(yīng)考慮。

This is particularly important for precision machinery and instruments. Linear guide rail deformation includes deformation of the guide rail body, contact deformation of the guide rail pair, and the ability of the guide rail to resist force deformation. Deformation will affect the relative position and guidance accuracy between components. Both should be considered.

抗振性與穩(wěn)定性

Vibration resistance and stability

而穩(wěn)定（解釋:穩(wěn)固安定；沒有變動(dòng))性是指在給定的運(yùn)轉(zhuǎn)條件下不出現(xiàn)自激振動(dòng)的性能。抗振性是指導(dǎo)軌副接受受迫振動(dòng)和沖擊的能力。

And stability (explanation: stability and stability; no fluctuation) refers to the performance of not experiencing self-excited vibration under given operating conditions. Vibration resistance refers to the ability of the guide rail pair to withstand forced vibration and impact.
