Preferably, carry in the edger roll bearing of sealing above-mentioned, the cross section of described seal ring takes the shape of the letter U, and opening is towards described rolling element, retainer.
Preferably, carry in the edger roll bearing of sealing above-mentioned, the cross section of described sealing gland is L-shaped, and the outer side surface of described seal ring is provided with step and puts on described seal ring to make the inner side surface of described sealing gland closely press.
Preferably, carry in the edger roll bearing of sealing above-mentioned, also comprise: support ring, ringwise, cross section is L-shaped, and on the inner side surface of the described support ring outer side surface that is set in described inner ring respectively and end face; The outer side surface put at described support ring is then closely pressed in one side of described seal ring.
Another aspect of the present utility model is a kind of milling train, comprises edger roll, and this edger roll is installed on milling train by above-described edger roll bearing.
Analyze known, the utility model provides a kind of edger roll bearing carrying sealing being applicable to steel rolling, it comprises rolling element, outer ring, inner ring, retainer, seal ring, sealing gland, this bearing structure carrying dust sealing can effectively reduce impurity and enter Bearing inner in rolling process, guarantee Bearing inner cleans, prevent impurity wearing and tearing rolling element, extend the working life of bearing.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 3, the utility model embodiment comprises support ring 6, seal ring 7, the sealing gland 8 that outer ring 2, rolling element 3, retainer 4 (specifically as shown in Figure 4), inner ring 5 (specifically as shown in Figure 5) and Fig. 6 are shown in detail.
Specifically, rolling element 3 embeds in the hole 41 (as Fig. 4) of retainer 4, the while of rolling element 3 and retainer 4 between the inner side surface of the outer side surface of inner ring 5, outer ring 2.As shown in Fig. 3, Fig. 6, the left and right end face of inner ring 5 and the junction of its outer side surface are arranged with support ring 6.Seal ring 7 is sheathed on the outer side surface of this support ring 6.Preferably, seal ring 7 is the U-shaped of opening towards rolling element 3, retainer 4, and it comprises outer aerofoil 71, inner airfoil surface 72, and the outer side surface of the inner airfoil surface 72 of seal ring 7 and the outer side surface of inner ring 5 are combined closely, sealed.The end face of the outer aerofoil 71 of seal ring 7 supports the end face in outer ring 2 scrupulously, the two sealing.Whereby, seal ring 7 can avoid retainer 4, rolling element 3 is exposed to the external world, makes retainer 4, the impurity in rolling element 3 and the external world keeps isolation.In order to position that is stable, that reinforce seal ring 7, it is made to move, the present embodiment is provided with sealing gland 8, it ringwise, be sheathed on seal ring 7, for position that is stable, fit sealing ring 7, and the outer surface of sealing gland 8 is concordant with the outer side surface of outer ring 2, can not affect the assembling of edger roll like this.
The material of seal ring 7 can be rubber etc., and sealing gland 8 can adopt the material such as metal, rigid plastics.
As shown in Fig. 3, Fig. 6, the cross section of seal ring 7 takes the shape of the letter U, and comprises the outer aerofoil 71 of level, inner airfoil surface 72, and opening is towards rolling element 3, retainer 4.The outer side surface of outer aerofoil 71 is step-like, and adapt therewith, the cross section of sealing gland 8 is L-shaped, and the step on the inner side surface of sealing gland 8 and outer aerofoil 71 strictly coincide, and the inner side surface of sealing gland 8 is closely pressed and puts on seal ring 7.
In addition, the present embodiment also comprises support ring 6, its ringwise, cross section is also L-shaped, on the outer side surface that inner side surface is set in inner ring 5 respectively and end face.The outer side surface of the inner airfoil surface 72 of seal ring 7 is closely pressed and is put on the outer side surface of support ring 6.
Again as shown in Figure 3, the internal diameter of support ring 6 is identical with the internal diameter of inner ring 5, and also, the two is set on edger roll mandrel simultaneously.
In addition, another mode of execution of the present utility model is a kind of milling train, comprises edger roll, and this edger roll is installed on milling train by above-described edger roll bearing.
In sum, seal ring of the present utility model can effectively stop in rolling process, and iron scale powder enters bearing roller inside.The design of sealing gland ensures to prevent the installation stability of seal ring seal ring from coming off because of impact in rolling process, enter rolling element inside, cause the accident of bearing fault.
As known by the technical knowledge, the utility model can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Allly all to be included in the utility model within the scope of the utility model or being equal to the change in scope of the present utility model.
