Description
Technical field
The utility model relates to a kind of bearing seal structure, particularly a kind of deep groove ball bearing sealing configuration.
Background technique
Under prior art, the sealing configuration of bearing directly determines the working life of bearing.Lack the bearing of lubricant oil, not only easily wear and tear, and for whole equipment, all may cause fatal impact.Current bearing, especially deep groove ball bearing, its sealing configuration is generally adopt seal ring, and in order to increase sealing effect, then adopt multi-layer sealed circle, its structure is not only complicated, and sealing effect is general.
Summary of the invention
In order to solve the problem of prior art, the utility model provides a kind of deep groove ball bearing sealing configuration, and its sealing effect is better, and convenient for installation and maintenance.
The technological scheme that the utility model adopts is as follows:
A kind of deep groove ball bearing sealing configuration, comprise inner ring and outer ring, one group of steel ball is had by retainer inlay card between described inner ring and outer ring, interior ring outer wall and outer ring inwall are provided with draw-in groove, back-up ring is respectively arranged with in described draw-in groove, back-up ring relative misalignment on inner ring and outer ring, its cross section is curved shape and bending to steel ball direction.
Bending back-up ring relative misalignment design, can play the effect of double layer screen, and lubricant oil is internally held together, and further reduces leaking outside of lubricant oil to Bearing inner by back-up ring.
Back-up ring comprises base portion and curved part, and described base portion is fixed in described draw-in groove, bottom described curved part to top extend and diameter of section reduce gradually.The base portion cross section of back-up ring is rounded, and it coordinates with the circular mutual inlay card of draw-in groove, not only convenient installation, and fixation, difficult drop-off.Curved part diameter of section reduces gradually, coordinates and adopts some soft rubber materials, the elasticity of back-up ring can be made better, make it be out of shape easily, keep aduncate state always, maintains oily effect.
Hangnail portion is provided with inside curved part.The design in hangnail portion, makes lubricant oil be not easy to flow to the top of curved part, more decreases the situation that lubricant oil may leak, and in addition, hangnail portion can also strengthen the toughness of curved part.
The top of curved part and inner ring or outer ring keep interference fit.Keep interference fit can stop that lubricant oil leaks outside further.
The beneficial effect that the technological scheme that the utility model provides is brought is:
Designed by the relative misalignment of bending back-up ring, make the lubricant oil in bearing be not easy to leak, and between back-up ring and inner ring and outer ring, mounting type is simple, once back-up ring is aging, is easy to change.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is that the structure of a kind of deep groove ball bearing sealing configuration of the present utility model partly cuts open schematic diagram;
Fig. 2 is the radial cross section schematic diagram of the back-up ring of a kind of deep groove ball bearing sealing configuration of the present utility model.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.
Embodiment one
As shown in Figure 1, a kind of deep groove ball bearing sealing configuration, comprise inner ring 1 and outer ring 2, one group of steel ball 4 is had by retainer 3 inlay card between described inner ring 1 and outer ring 2, inner ring 1 outer wall and outer ring 2 inwall are provided with draw-in groove 5, be respectively arranged with back-up ring 6 in described draw-in groove 5, inner ring 1 and back-up ring 6 relative misalignment on outer ring 2, its cross section is curved shape and bends to steel ball 4 direction.
Back-up ring 6 in the present embodiment comprises base portion 61 and curved part 62, and described base portion 61 is fixed in described draw-in groove 5, bottom described curved part 62 to top extend and diameter of section reduce gradually.
For increasing sealing effect, inside curved part 62, be provided with hangnail portion 63.The design in hangnail portion 63, makes lubricant oil be not easy to flow to the top of curved part, more decreases the situation that lubricant oil may leak, and in addition, hangnail portion 63 can also strengthen the toughness of curved part.
In the present embodiment, the top of curved part 62 can keep interference fit with inner ring 1 or outer ring 2.Keep interference fit can stop that lubricant oil leaks outside further.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (4)
1. a deep groove ball bearing sealing configuration, comprise inner ring and outer ring, one group of steel ball is had by retainer inlay card between described inner ring and outer ring, it is characterized in that, described interior ring outer wall and outer ring inwall are provided with draw-in groove, be respectively arranged with back-up ring in described draw-in groove, the back-up ring relative misalignment on inner ring and outer ring, its cross section is curved shape and bending to steel ball direction.
2. a kind of deep groove ball bearing sealing configuration according to claim 1, it is characterized in that, described back-up ring comprises base portion and curved part, and described base portion is fixed in described draw-in groove, bottom described curved part to top extend and diameter of section reduce gradually.
