For oil lubrication, the sealing method of filling grease in the sealed guide rail in advance, and the filling and grease supply method of filling proper amount of grease in the shell and replenishing or replacing at intervals are required.

此外，對有多處滑軌需要潤滑的機(jī)械，還采用管道連接各潤滑處的集中供脂方式。脂潤滑可做到填充一次潤滑油脂后長時間不需要補(bǔ)充，而且其密封裝置的結(jié)構(gòu)也較簡單，因此使用廣泛。油潤滑相對來說比較簡單，經(jīng)常潤滑能大大提升直線導(dǎo)軌的使用壽命及保持一定的精度和預(yù)壓。

In addition, the centralized grease supply mode with pipes connected to each lubrication place is also adopted for the machinery with multiple sliding rails needing lubrication. Grease lubrication can be filled with grease for a long time without supplement, and the structure of its sealing device is simple, so it is widely used. Oil lubrication is relatively simple, regular lubrication can greatly improve the service life of linear guide and maintain a certain precision and preloading.

1、從摩擦負(fù)擔(dān)得起的加載考慮。平方計是平方線性導(dǎo)軌面接觸摩擦。摩擦較大。均布荷載。需要經(jīng)常油潤滑但圓形導(dǎo)軌是圓柱形線性導(dǎo)軌。摩擦小。因為它是一系列的點接觸滾珠軸承。支持是有限的。剛性差負(fù)載性能是有限的。只有徑向載荷具有良好的承載力、軸向載荷很小。而方形導(dǎo)軌耐磨、高速、阻力小，所以更具優(yōu)勢。

1. From the consideration of friction affordable loading. The square meter is the contact friction of the square linear guide surface. The friction is large. Uniform load. Regular oil lubrication is required, but the circular guide rail is a cylindrical linear guide rail. The friction is small. Because it's a series of point contact ball bearings. Support is limited. The difference of rigidity and load performance is limited. Only the radial load has good bearing capacity and the axial load is very small. The square guide rail is wear-resistant, high-speed, low resistance, so it has more advantages.

2、上銀直線導(dǎo)軌產(chǎn)品功能定位精度高。摩擦系數(shù)小。尤其是靜摩擦力和摩擦力之間的差距很小。即使不會有空閑打滑現(xiàn)象。

2. Shangyin linear guide products have high function positioning accuracy. The friction coefficient is small. Especially the gap between static friction and friction is very small. Even if there is no idle slip.

分析能力再現(xiàn)性。因此可以實現(xiàn)木工雕刻機(jī)可以維持很長一段時間的精密直線導(dǎo)軌滾動摩擦μm水平的定位精度。低摩擦阻力，易潤滑，可降低導(dǎo)軌的滑動阻力1/20~1/40，特別潤滑結(jié)構(gòu)簡單。摩擦接觸面磨損低，滑動效果好。行走精度可以長期保持。

Analysis ability and reproducibility. Therefore, the precision linear guide rolling friction of woodworking engraving machine can be maintained for a long time μ The positioning accuracy of m level. Low friction resistance, easy lubrication, can reduce the sliding resistance of guide rail 1 / 20 ~ 1 / 40, especially simple lubrication structure. The friction contact surface has low wear and good sliding effect. The walking accuracy can be maintained for a long time.
