Further, the interference fit amount of interference of described mounting cylinder and described axis hole is 0.02-0.32mm.
Further, described capping has arc convex face, and described arc convex face dorsad described mounting cylinder direction is arranged.
Further, described mounting cylinder and described capping one-body molded.
Further, described mounting cylinder and described capping shaping by steel plate integrated punching.
The hub seal bearing structure that the utility model provides is simple, easy to assembly, and the shaft hole inner wall by being obliquely installed, improve bearing body to the fixing soundness of end cap and stability, avoid end cap come off and affect the sealing of hub bearing.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of preferred hub seal bearing of the utility model;
Fig. 2 is the end cap schematic diagram of the hub seal bearing shown in Fig. 1.
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 depicted in figs. 1 and 2, the hub seal bearing that the utility model provides comprises bearing body 1, the axis hole of described bearing body 1 is provided with end cap 2, the capping 22 that described end cap 2 comprises mounting cylinder 21 and is connected with described mounting cylinder 21, described mounting cylinder 21 with the axis hole interference fit of described bearing body 1, the shaft hole inner wall of described bearing body 1 is the cambered surface be obliquely installed, described cambered surface is shunk to the root of described axis hole gradually from the port of described axis hole, and namely the aperture of described axis hole reduces to root gradually from port.
During use, as shown in Figure 1, the mounting cylinder 21 of described end cap 2 is pressed into by interference fit in the axis hole of described bearing body 1, the mounting cylinder 21 of described end cap 2 is clamped in the axis hole of described bearing body 1, thus described capping 22 is located on the end face of described axis hole, realize the sealing to described hub bearing.
What those skilled in the art should understand that is, the aperture of described axis hole reduces to root gradually from port, the clamping dynamics of the inwall of described axis hole to the mounting cylinder 21 of described end cap 2 can be made to increase gradually, thus ensure that described end cap 2 can be securely fixed on described bearing body 1, avoid end cap 2 come off and affect the sealing of hub bearing.
The shaft hole inner wall of bearing body 1 of the present utility model tilts also to contribute to end cap 2 to install on axis hole to root from the port of axis hole, larger axis hole port is convenient to aim at the mounting cylinder 21 of end cap 2, can more quickly end cap 2 be pressed on the axis hole of bearing body 1 by this, improve the efficiency of assembling of hub seal bearing.
What those skilled in the art should understand that is, although the shaft hole inner wall be obliquely installed can improve the constant intensity of end cap 2, improve efficiency of assembling simultaneously, but, if the excessive assembling being unfavorable for end cap 2 on the contrary in shaft hole inner wall angle of inclination, the reaction force that described end cap appearance 2 is subject to shaft hole inner wall is excessive, easily comes off in axis hole.Given this, the angle of inclination of the cambered surface of axis hole of the present utility model is preferably set to 0.1 °-5 °.Certainly, the angle of inclination of above-mentioned cambered surface is only a kind of preferred version of the present utility model, and the angle of inclination of shaft hole inner wall of the present utility model can also need to carry out accommodation according to practical set, repeats no more herein.
In order to ensure the sealing effect of end cover, avoiding installing difficulty simultaneously, improving installation efficiency, described mounting cylinder 21 is preferably set to 0.02-0.32mm with the interference fit amount of interference of described axis hole by the utility model.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 bearing body 1 to interference fit amount of interference, repeat no more herein.
As a kind of preferred version of the present utility model, as shown in Figure 1, described capping 22 has arc convex face, and described arc convex face dorsad described mounting cylinder 21 direction is arranged.What those skilled in the art should understand that is, described mounting cylinder 21 is under the clamping action of the tilt internal wall of described axis hole, described mounting cylinder 21 is subject to increasing gradually towards the active force of axis direction, described active force is further advanced by described mounting cylinder 21 and is passed to described capping 22, namely arc convex face is passed to, described arc convex face is subject to external force and easily produces bending, when described active force increase to described capping 22 can be made to produce bending time, the internal diameter of described mounting cylinder 21 starts to shrink, thus is convenient to described mounting cylinder 21 to be installed in described axis hole.
As a kind of preferred version of the present utility model, described mounting cylinder 21 and described capping 22 one-body molded, the one-body molded join strength that can not only improve described mounting cylinder 21 and described capping 22, extend the working life of end cover, also contribute to improving the sealing between described mounting cylinder 21 and described capping 22, avoid the gap between described mounting cylinder 21 and described capping 22 and affect the problem of end cover sealing.
On the basis of above-described embodiment, described mounting cylinder 21 and described capping 22 are more preferably shaping by steel plate integrated punching, and described steel plate is preferably cold-rolled carbon steel thin plate.What those skilled in the art should understand that is, steel plate is only the utility model for a kind of preferred version of mounting cylinder described in integrated punching 21 and described capping 22, the utility model can also adopt other material known in those skilled in the art to prepare end cap, repeats no more herein.
In sum, the hub seal bearing structure that the utility model provides is simple, easy to assembly, and the shaft hole inner wall by being obliquely installed, improve bearing body to the fixing soundness of end cap and stability, avoid end cap come off and affect the sealing of hub bearing.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment's technological scheme of the utility model.
