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
The present invention relates to a kind of slide guide, especially relate to the slide guide of the little hole of a kind of matrix surface band oil bag.
Background technique
Slide guide is known in the art, and the slideway of common slide guide directly contacts, and the rough surface peak directly contacts, and can not form the liquid lubrication film.See that from frictional property common slide guide belongs to the mixed friction state with certain dynamic pressure effect, but its dynamic pressure effect is not enough to far also separate slideway.Though this rail configurations is simple, easily manufactured, contact stiffness is high, shock resistance is good, surface friction drag is big, quick abrasion.
In view of the foregoing, hope can improve the dynamic pressure effect of guide rail, to improve the operating conditions of guide rail, produces that a kind of wear resistance is good, the significant slide guide of lubrication effect.
Summary of the invention
The object of the present invention is to provide the slide guide of the little hole oil bag of a kind of matrix surface band, is a kind ofly to have little hole oil bag at quiet guide rail matrix surface, and the slide guide of one deck soft material that bonds on the matrix.Traditional slide guide that the improvement problem is more, a kind of wear resistance is good in the hope of obtaining, the significant slide guide of lubrication effect.
The technological scheme that the present invention adopts is:
The present invention has equally distributed little hole oil bag, bonding one deck soft material on quiet guide rail matrix at quiet guide rail matrix surface.
Little hole oil of described quiet guide rail matrix surface wraps along many parallel, equidistance arrangements of quiet rail length direction, or along many parallel, every equidistance dislocation arrangements of quiet rail length direction.
Little hole oil bag gross area of described quiet guide rail matrix surface is 5% ~ 20% of a quiet guide rail surface of the base body.
Little hole oil bag aspect ratio scope of described quiet guide rail matrix surface is 0.1 ~ 0.7.
Described quiet guide rail body material is cast iron or carbon steel; Described soft material is MoS
2Doped graphite or MoS
2Doping PTFE composite solid lubricant material, the modular ratio of soft material and quiet guide rail matrix is 0.007～0.014.
The beneficial effect that the present invention has is:
1, the surface of quiet guide rail matrix is uniform-distribution with little hole oil bag, bonding one deck soft material on the matrix.The lubrication principle of imitation human synovial, guide rail are when receiving downward pressure, and soft material is bigger in the part depression of the oil side of wrapping, little hole; Storing lubricating oil; Thereby between moving guide rail and quiet guide rail, form the elastic hydrodynamic lubrication oil film, the wearing and tearing of reducing friction, the life-span of assurance kinematic pair.
2, owing to the soft material easy deformation, the dynamic pressure oil film between moving guide rail and the quiet guide rail will be in the elastic hydrodynamic lubrication state, and the guide rail wear resistance is good, and lubrication effect is obvious.
3, oil bag in the little hole of quiet guide rail matrix surface is evenly distributed regularly, and processing is simple; Can bond together between soft material and the quiet guide rail matrix, be easy to make.
The present invention is specially adapted to the slide guide of boundary lubrication and Mixed lubrication.
