Abstract
The utility model discloses a sexfarious cylindrical roller bearing applied in the roller of the roll mill, comprising an outside track, an inner track, a cylindrical roller and two cages; wherein, the inner track and the outside track are respectively arranged on the inner side and the surface of the cage. The utility model is characterized in that the cylindrical roller is positioned at the center of the cage; the cylindrical roller row of every cage is three; and there exists some gap between the adjacent cylindrical rollers. The utility model has the advantages of high loading capacity, great durability and long life span.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of roller bearing that is used on the milling train.
Background technique
The existing roller bearing that is used on the rolling mill roll is mainly four-line column roller bearing, and it comprises two retainers, and the both sides of each retainer are separately installed with the columna roller.In the working procedure of milling train, bearing will bear huge load, and axial float can take place roll, four-line column roller bearing damages than being easier under such working environment, therefore to often change bearing, increase the maintenance cost of milling train, influence the manufacturing efficiency of milling train.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide that a kind of bearing capacity is big, durable, the life-span is long is used for roller bearing on the rolling mill roll.
The technological scheme that its technical problem that solves the utility model adopts is: be used for the six-row cylindrical roller bearing on the rolling mill roll, comprise outer ring, inner ring, cylindrical roller and two retainers, inner ring and outer ring are installed in the inboard and surperficial of retainer respectively, it is characterized in that: cylindrical roller is positioned at the centre of retainer, the columns of the cylindrical roller of each retainer is three row, has certain clearance between the adjacent cylindrical roller.
As further improvement of the utility model, described retainer mainly is made up of support and back-up ring, and back-up ring is riveted on the support.
As further improvement of the utility model, described outer ring and inner ring are respectively two, are provided with middle-grade limit between two outer rings, and both sides are provided with the overside limit.
The beneficial effects of the utility model are: because cylindrical roller is positioned at the centre of retainer, the columns of the cylindrical roller of each retainer is three row, there is certain clearance between the adjacent cylindrical roller, when the cylindrical roller of edge two row bears different loads, will to the gap move and shift in the middle of cylindrical roller, middle cylindrical roller will offset or share the load of the cylindrical roller of edge two row, thereby the load that rolling mill roll is acted on the bearing is distributed to the roller that each is listed as equably, make the utility model can bear bigger load, thereby prolong working life of the present utility model greatly, therefore the utlity model has durable reliable advantage.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the decomposition texture schematic representation of the utility model preferred embodiment;
Fig. 2 is the stereogram of the utility model preferred embodiment.
Embodiment
With reference to Fig. 1, Fig. 2, be used for the six-row cylindrical roller bearing on the rolling mill roll, comprise outer ring 1, inner ring 2, cylindrical roller 3 and two retainers 4, inner ring 2 and outer ring 1 are installed in the inboard and surperficial of retainer 4 respectively, cylindrical roller 3 is positioned at the centre of retainer 4, the columns of the cylindrical roller 3 of each retainer 4 is three row, has certain clearance 5 between the adjacent cylindrical roller 3.When the cylindrical roller 3 of edge two row bears different loads, will to gap 5 move and shift in the middle of cylindrical roller 3, middle cylindrical roller 3 will offset or share the load of the cylindrical roller 3 of edge two row, thereby the load that rolling mill roll is acted on the bearing is distributed on the roller of each row equably, make the utility model can bear bigger load, thereby prolong working life of the present utility model greatly, therefore the utlity model has durable reliable advantage.
In order to prevent the bearing root fracture of retainer in the course of the work, described retainer 4 mainly is made up of support 6 and back-up ring 7, and back-up ring 7 is riveted on the support 6.
Wherein, described outer ring 1 and inner ring 2 are respectively two, are provided with middle-grade limit 8 between two outer rings 1, and both sides are provided with overside limit 9, thereby it is practical more reliable that the utility model is used.
Certainly, the utility model is equal to or becomes bad technological scheme with the utility model and also should belong within the protection domain of the present utility model except the foregoing description.
