Abstract
The utility model discloses a sealing structure for a rolling linear guide. The sealing structure comprises a guide (1) and a slider component (2) matched with the guide (1). Sealing end caps (3) are arranged at two ends of the slider component (2), a flexible sealing strip (4) is arranged between each of the sealing end caps (3) and the guide (1), and a bottom sealing gasket (6) is arranged on a contact portion of the lower end of the slider component (2) contacting with the guide (1). The sealing structure is characterized in that the flexible sealing strips (4) are provided with flexible grooves (5) matched with the outer profile of the cross section of the guide (1), and the bottom sealing gasket (6) is also provided with flexible grooves (6) along the axial direction of the guide (1). The sealing structure has the advantages of simple structure, skillful design, avoidance of affecting stability of linear motion on the premise of guaranteeing fine sealing effect and the like.
Description
Technical field
The utility model relates to a kind of sealing configuration, and especially a kind of rolling linear guide is used, and can keep the sealing configuration of excellent sealing effect on the basis that guarantees robust motion.
Background technique
Rolling linear guide is a kind of accurate guiding and load-carrying unit, be widely used in printing, medical treatment, carpenter, glass, packing and engineering machinery field, and when rolling linear guide is applied in these fields, owing to do not allow oil leak, the working environment dust is more to wait restriction, and the sealing of linear rolling guide has just been proposed very high requirement.In order to reach the better seal effect, general way is to add certain magnitude of interference (interference fit) in advance between Sealing in the moving element and the guide rail now, reaches the purpose that the leakage that prevents lubricant oil or dust enter linear guide pairs inside; But because the restriction of material itself and moulding process level; its magnitude of interference through regular meeting greater than design load; make and form the rigidity contact between the two; increase because of fricative resistance when causing moving; the working life of motion-affecting stationarity and product; if and magnitude of interference does not reach design load, though can guarantee to move carry out the sealing effect extreme difference smoothly.Therefore need a kind of new-type rolling linear guide pairs sealing configuration that can address the above problem now.
Summary of the invention
The utility model is in order to solve existing in prior technology the problems referred to above, to provide a kind of simple in structure, designs ingeniously, is guaranteeing not influence the linear rolling guide sealing configuration of straight line motion stationarity under the sealing effect good premise.
Concrete solution of the present utility model is: a kind of linear rolling guide sealing configuration, comprise guide rail 1 and associated sliding assembly 2, be provided with end cover 3 at the two ends of sliding assembly 2, be provided with flexible sealing strip 4 between end cover 3 and the guide rail 1, the lower end of sliding assembly 2 and guide rail 1 contact segment also are provided with sealing egative film 6, it is characterized in that: offer the flexible slot 5 that the section outer contour with guide rail 1 matches on the described flexible sealing strip 4, described sealing egative film 6 upper edge guide rails 1 axial direction offers flexible slot 5.
The utility model is compared with prior art, has following advantage:
This structure simple in structure, design ingenious, creatively on traditional flexible sealing strip, set out flexible slot for Stamping Steel Ribbon generation resiliently deformable, solved traditional linear rolling guide in order to pursue excellent sealing performance, the increase frictional force that Sealing and guide rail interference fit are produced, the slack problem of moving under the condition that guarantees sealability, can not exert an influence to straight line motion; And this structure is to make improvements on the basis of conventional construction, so it is with low cost, and easy to make, this device possesses extensive market prospects, very helps applying in the art.
Description of drawings
Fig. 1 is the utility model embodiment's a plan view.
Fig. 2 be the utility model embodiment A-A to sectional view.
Fig. 3 is the B portion enlarged view of Fig. 2.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.As Fig. 1, Fig. 2, shown in Figure 3: a kind of linear rolling guide sealing configuration, comprise guide rail 1, on guide rail 1, is furnished with sliding assembly 2 mutually with it, the two ends of sliding assembly 2 are provided with end cover 3, be provided with flexible sealing strip 4 in end cover 3 and guide rail 1 contacted part, and offer flexible slot 5 on flexible sealing strip 4, the outer contour of the shape of flexible slot 5 and guide rail 1 section is consistent; In the lower end of sliding assembly 2,, also be provided with sealing egative film 6, and on sealing egative film 6, offer equally simultaneously along the flexible slot 5 of guide rail 1 axial direction with guide rail 1 contacted part.
The working procedure of the utility model embodiment's linear rolling guide sealing configuration is as follows: when sliding assembly 2 is made reciprocal straight line motion on guide rail 1, when the gap smaller that causes owing to reasons such as machining errors between guide rail 1 and the end cover 3, because the existence of flexible slot 5, flexible sealing strip 4 and sealing egative film 6 just can push in flexible slot 5 with guide rail 1 contacted part, when this gap returns to reference value, flexible slot 5 restores to the original state, and guarantees that still flexible sealing strip 4 contacts with the good of guide rail 1 with sealing egative film 6; This structural type can guarantee on the one hand flexible sealing strip 4 and sealing egative film 6 can keep all the time with guide rail 1 between tight the contact, to prevent that oil leakage and extraneous dust in the linear rolling guide from entering guiding pairs inside, guarantee good working environment, prolonged the working life of this device; On the other hand when the slit between guide rail 1 and the end cover 3 dwindles suddenly owing to a variety of causes, resiliently deformable can take place in flexible slot 5 automatically, this resiliently deformable can guarantee that the way of contact between guide rail 1 and flexible sealing strip 4 or the sealing egative film 6 can not become rigidity and contact, so can not have influence on carrying out smoothly of motion.
In sum, this is a kind of favorable sealing property, and can guarantee the sealing configuration that moves and carry out smoothly, it has functional characteristics such as constant pressure, self adaption, the sealing effect of this structure is compared with conventional construction, can make the undulating value decline 25%-30% of frictional force, be a kind of sealing configuration of comparatively desirable linear rolling guide.
