Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawings and examples.

[0028] Such as figure 1 As shown, the present invention has evenly distributed micropit oil bags 3 on the surface of the static guide rail substrate 2, and a layer of soft material 1 is bonded on the static guide rail substrate 3.

[0029] Such as figure 2 As shown, the micropits 3 on the surface of the base body 2 of the static guide rail are arranged in parallel and equidistantly along the length direction of the static guide rail. Or along the length direction of the static guide rails, multiple parallel ones, each equidistantly arranged in dislocation.

[0030] The total area of ​​the micropit oil pockets 3 on the surface of the static guide rail base 2 is 5% to 20% of the surface area of ​​the static guide rail base. Such as image 3 , the area ratio of the oil pocket area of ​​a micropit to the corresponding matrix area .

[0031] The depth-to-di...

Abstract

The invention discloses a sliding guide rail with micro-pit oil pockets on the surface of a base. The micro-pit oil pockets are uniformly distributed on the surface of the base of a fixed guide rail, and a layer of a flexible material is adhered on the base of the fixed guide rail. A lubricating principle of a human joint is imitated, when the guide rail is pressed downwards, sunken parts, which are positioned above the micro-pit oil pockets, of the flexible material are large and store lubricating oil, accordingly, an elastic flowing hydrodynamic lubricating oil film is formed between a movable guide rail and the fixed guide rail, frictional abrasion is reduced, and the service life of a kinetic pair is guaranteed. In addition, the flexible materials are easy to deform, the dynamic-pressure oil film between the movable guide rail and the fixed guide rail is in an elastic hydrodynamic lubrication state, abrasion resistance of the guide rails is good, and a lubricating effect is obvious. Further, the micro-pit oil pockets are uniformly and regularly distributed on the surface of the base of the fixed guide rail, and the sliding guide rail is simple in processing. Besides, the flexible materials can be adhered with the base of the fixed guide rail, and the sliding guide rail is easy to manufacture. The invention is particularly applicable to sliding guide rails with boundary lubrication and mixture lubrication effects.

Description

technical field [0001] The invention relates to a sliding guide rail, in particular to a sliding guide rail with micropit oil pockets on the surface of a substrate. Background technique [0002] Sliding guide rails are well known in the prior art. The guide rail surfaces of ordinary sliding guide rails are in direct contact, and the surface roughness peaks are in direct contact, so a liquid lubricating film cannot be formed. From the perspective of friction properties, the ordinary sliding guide rail belongs to the mixed friction state with certain dynamic pressure effect, but its dynamic pressure effect is far from enough to separate the guide rail surface. Although this kind of guide rail has simple structure, convenient manufacture, high contact stiffness and good shock resistance, it has large frictional resistance and fast wear. [0003] In view of the above situation, it is hoped that the dynamic pressure effect of the guide rail can be improved to improve the working...
