Guiding accuracy

以及滑轨和支承件的热变形等。导向精度是指运动构件沿导轨导面运动时其运动轨迹的准确水平。影响导向精度的主要因素有导轨承导面的几何精度导轨的结构类型导轨副的接触精度外表粗糙度导轨和支承件的刚度导轨副的油膜厚度及油膜刚度。直线运动导轨的几何精度一般包括：垂直平面和水平平面内的直线度；两条导轨面间的平行度。导轨几何精度可以用导轨全长上的误差或单位长度上的误差表示。

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.

精度坚持性

Accuracy persistence

另外，精度坚持性是指滑轨工作过程中保持原有几何精度的能力。导轨的精度坚持性主要取决于导轨的耐磨性及尺寸稳定性。耐磨性与导轨副的资料匹配受力加工精度润滑方式和防护装置的性能的因素有关。导轨及其支承件内的剩余应力也会影响导轨的精度坚持性。

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.

运动平稳性

Motion stability

导轨运动平稳性是指导轨在低速运动或微量移动时不出现爬行现象的性能。平稳性与导轨的结构导轨副材料的匹配润滑状况润滑剂（作用：能减少或避免摩擦磨损）性质及导轨运动之传动系统的刚度等因素有关。

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.

运动灵敏度和定位精度

Motion sensitivity and positioning accuracy

直线模组运动灵敏度是指运动构件能实现的行程；定位精度是指运动构件能按要求停止在指定位置的能力。运动灵敏度和定位精度与导轨类型摩擦特性运动速度传动刚度运动构件质量等因素有关。

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.

刚度

Stiffness

这对于精密机械与仪器尤为重要。直线导轨变形包括导轨本体变形导轨副接触变形，导轨抵抗受力变形的能力。变形将影响构件之间的相对位置和导向精度。两者均应考虑。

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.

抗振性与稳定性

Vibration resistance and stability

而稳定（解释:稳固安定；没有变动)性是指在给定的运转条件下不出现自激振动的性能。抗振性是指导轨副接受受迫振动和冲击的能力。

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.
