Description
Technical field
The utility model relates to metallurgical steel rolling equipment technical field, and specifically, the utility model is in particular to a kind of milling train edger roll bearing.
Background technology
In metallurgical steel rolling production process, the general universal mill form that adopts produces product, particularly in Section Steel Production.The form that universal mill structure adopts horizontal roll to match with edger roll, vertical roll of rolling plays the shaping effect with ensureing surface quality of rolled piece, as shown in Figure 1, it illustrates the assembly structure of vertical roll of rolling: it is inner that edger roll 11, edger roll bearing 12, edger roll mandrel 13 are arranged at edger roll casing 14.
Aborning, due to steel rolling process problem, rolled piece may be caused to produce the problem in partially first-class various harm milling train service life, such as cause milling train particularly vertical roll of rolling bearing damage.Specifically, in milling train occlusion process, the inclined head of rolled piece produces very large impact to vertical roll of rolling, and particularly in large gauge shaped steel product, this impact will cause the damage such as inner ring, roller holder cracking of edger roll bearing.
In sum, be necessary to improve from bearing material and/or structure, improve bearing serviceability.
Summary of the invention
The purpose of this utility model is to provide a kind of milling train edger roll bearing, with the problem solving the inner ring of the vertical roll of rolling bearing of existing existence, retainer easily ftractures.
In order to solve the problem, the technical scheme that the utility model provides is as follows:
A kind of milling train edger roll bearing, comprise outer ring, inner ring, rolling element, retainer, described rolling element embeds in described retainer, described rolling element and retainer are positioned at the outer surface of described inner ring, between the inner surface of described outer ring, and the outer surface of described inner ring is provided with the rolling element groove for holding described rolling element of annular, the outside of described rolling element groove is for preventing the rolling element shelves limit of described rolling element play, wherein, the end face adjacent with described rolling element shelves limit of described rolling element is provided with groove, described groove matches with described rolling element shelves limit, excessive shifting amount is had in the axial direction to prevent described rolling element, described rolling element shelves limit tilts to extend to described groove direction.
The utility model provides one to be applicable to milling train edger roll bearing, and it comprises rolling element, outer ring, inner ring, retainer, thus, make the utility model can improve shock resistance on the whole, ensure product quality.
Accompanying drawing explanation
Fig. 1 is the assembly structure schematic diagram of existing vertical roll of rolling;
Fig. 2 is the structural representation of the utility model embodiment;
Fig. 3 is the structural representation of the rolling element of the utility model embodiment;
Fig. 4 is the structural representation of the inner ring of the utility model embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 2, the utility model embodiment comprises outer ring 2, inner ring 5, rolling element 3, retainer 4, and rolling element 3 embeds in retainer 4, between rolling element 3 and retainer 4 inner surface generally within the outer surface of inner ring 5, outer ring 2.As Fig. 4, the outer surface of inner ring 5 is provided with the rolling element groove 50 for holding rolling element 3, the rotation of confession rolling element 3 of annular, and the outside of rolling element groove 50 is for preventing the rolling element shelves limit 51 of rolling element 3 play.In the inner side of rolling element groove 50, as Fig. 2, part A is the contact point of rolling element 3 and inner ring 5.In order to increase the anti-impact force of the present embodiment, as Fig. 3, the end face that rolling element 3 is adjacent with rolling element shelves limit 51 is provided with groove 31, and groove 31 matches with rolling element shelves limit 51, has excessive shifting amount in the axial direction to prevent rolling element 3.Rolling element shelves limit 51 tilts to extend to groove 31 direction, and rolling element shelves limit 51 can more be stretched in groove 31.
Analyze known, in the present embodiment, rolling element 3 designs groove, the stability on its retainer 4 can be increased in, because after rolling element 3 designs groove 31, match with the inclined design on rolling element shelves limit 51 in the axial direction, prevent rolling element 3 from having excessive shifting amount in the axial direction, ensure that it is stable on retainer 4.For inner ring 5, by rolling element shelves limit 51 larger, can impact resistance be increased, because by rolling element shelves limit 51 larger, the play space of rolling element 3 can be reduced, reduce the impact momentum of rolling element 3, increase overall impact resistance.
In sum, the utility model adopts new structure, can improve impact resistance from structure.Adopt new material and Technology for Heating Processing, mechanical performance can be improved further.In addition, the utility model has wide range of applications, and is applicable to the improvement of Multiple Type bearing.
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.
