Further, described mounting cylinder is provided with multiple seal ring abreast.
Further, the outer wall of described mounting cylinder offers multi-turn establishes described seal ring groove for card abreast.
Further, the interference fit amount of interference of described mounting cylinder and described hub bearing is 0.02-0.32mm.
Further, described seal ring is rubber ring.
Further, described mounting cylinder and described capping one-body molded.
Further, described mounting cylinder and described capping shaping by steel plate integrated punching.
The end cover that the utility model provides not only can be sealed hub bearing by the interference fit between mounting cylinder and hub bearing, the seal ring be arranged between described mounting cylinder and hub bearing can also be utilized to carry out double seal to hub bearing, thus effectively improve the sealing effect of described end cover.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the end cover of a kind of preferred hub bearing of the utility model;
Fig. 2 be end cover and the bearing of the hub bearing shown in Fig. 1 coordinate schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is described in detail.The identical reference character of wherein identical component represents.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometrical center respectively.
As shown in Figure 1, the end cover of the hub bearing that the utility model provides comprises end cap body 1 and is set in the seal ring 2 on described end cap body 1, described end cap body 1 comprises for the mounting cylinder 11 with hub bearing 3 interference fit, the root of described mounting cylinder 11 is provided with the capping 12 for the circle of shutoff hub bearing 3, and described mounting cylinder 11 offers the groove establishing described seal ring 2 for card.
During use, as shown in Figure 2, be first set in by described seal ring 2 in the groove of described mounting cylinder 11, described seal ring 2 is under the position-limiting action of groove, cannot roll along the outer wall of described mounting cylinder 11 or slide, namely ensure that the relative position of described seal ring and described end cap body 1 is constant.Then, be pressed in hub bearing 3 by interference fit by the described end cap body 1 being arranged with seal ring 2, described seal ring 2 is out of shape under external force, is clamped between described mounting cylinder 11 and described hub bearing 3 and namely completes installation.
What those skilled in the art should understand that is, the end cover that the utility model provides not only can be sealed hub bearing 3 by the interference fit between mounting cylinder 11 and hub bearing 3, the seal ring 2 pairs of hub bearings 3 be arranged between described mounting cylinder 11 and hub bearing 3 can also be utilized to carry out double seal, thus effectively improve the sealing effect of described end cover.
As a kind of preferred version of the present utility model, as depicted in figs. 1 and 2, described mounting cylinder 11 offers described seal ring 2 established by circle groove for card in the one end be connected with described capping 12, it is interior and adjacent with described capping 12 that described seal ring 2 is fastened on described groove.During installation, described seal ring 2 is subject to the extruding of hub bearing 3 towards described capping 12 direction, establish described mounting cylinder 11 in the one end near described capping 12 on described seal ring 2 card, described capping 12 can stop slip on seal ring 2, thus effectively improve the stability of described seal ring 2, prevent described seal ring 2 from producing on described mounting cylinder 11 and roll and slide.
As another kind of preferred version of the present utility model, described mounting cylinder 11 is provided with multiple seal ring 2 abreast, correspondingly, the outer wall of described mounting cylinder 11 offers abreast multi-turn establishes described seal ring 2 groove for card.On described mounting cylinder 11, to establish multiple-sealed circle can be formed between described mounting cylinder 11 and hub bearing 3 multi-sealed for card, thus improve the sealing of end cover further.It will be understood by those skilled in the art that and on described mounting cylinder 11, to block the seal ring established the more, sealing effect better, but consider the problem of cost of production, the utility model is Ka She 1-2 road seal ring on described mounting cylinder 11 preferably.
In order to ensure the sealing effect of end cover, avoid installing difficulty, improve installation efficiency, the interference fit amount of interference between described mounting cylinder 11 and described hub bearing 3 is preferably set to 0.02-0.32mm by the utility model simultaneously.Certainly, above-mentioned interference fit amount of interference is only a kind of preferred version of the present utility model, and those skilled in the art can also carry out accommodation according to the material of mounting cylinder 11 and hub bearing 3 to interference fit amount of interference, repeat no more herein.
Seal ring 2 of the present utility model is preferably rubber ring, rubber ring can provide excellent elasticity, ensures that described seal ring 2 is when by external force extruding, can produce enough deformation, thus be squeezed between described hub bearing 3 and end cover, realize the sealing to hub bearing 3.In addition, rubber also has excellent toughness, thus ensures that rubber ring is not torn in the process of long extrusion-deformation, extends the working life of seal ring.
