直线导轨滚珠螺母油润滑的注意事项

来源:http://www.jngongrun.com/ 日期:2021-04-25 发布人:

油润滑要预先在密封型导轨中充填润滑油脂的密封方式,以及在外壳内部填充适量的润滑油脂,每隔一段时间进行补充或更换的填充供脂方式。

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,对有多处滑轨需要润滑的机械,还采用管道连接各润滑处的集中供脂方式。脂润滑可做到填充一次润滑油脂后长时间不需要补充,而且其密封装置的结构也较简单,因此使用广泛。油润滑相对来说比较简单,经常润滑能大大提升直线导轨的使用寿命及保持一定的精度和预压。
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、从摩擦负担得起的加载考虑。平方计是平方线性导轨面接触摩擦。摩擦较大。均布荷载。需要经常油润滑但圆形导轨是圆柱形线性导轨。摩擦小。因为它是一系列的点接触滚珠轴承。支持是有限的。刚性差负载性能是有限的。只有径向载荷具有良好的承载力、轴向载荷很小。而方形导轨耐磨、高速、阻力小,所以更具优势。
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、上银直线导轨产品功能定位精度高。摩擦系数小。尤其是静摩擦力和摩擦力之间的差距很小。即使不会有空闲打滑现象。
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.
分析能力再现性。因此可以实现木工雕刻机可以维持很长一段时间的精密直线导轨滚动摩擦μm水平的定位精度。低摩擦阻力,易润滑,可降低导轨的滑动阻力1/20~1/40,特别润滑结构简单。摩擦接触面磨损低,滑动效果好。行走精度可以长期保持。
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.
