Description
Technical field:
The utility model relates to a kind of bushing for roll, belongs to field of mechanical technique.
Background technology:
Roll is the important part on rolling mill, utilize one to or the pressure that produces when one group of roll rolls to roll stone roller steel. what existing roll great majority adopted is the roll of one-piece construction, roll in use weares and teares very serious, once reach wear limit, roll entirety can only be scrapped, cause a large amount of wastes of resource, too increase the acquisition cost of roll, in order to evade the defect existing for above-mentioned roll, sometimes roll is placed on lathe for machining by the surperficial car of roll and falls one layer, but the external diameter of roll can be reduced like this, thus roll can be made to run into problem in actual use, so industry needs a kind of roll being designed with novel texture, problems faced in current industry can be solved.
Summary of the invention:
Technical problem to be solved in the utility model is: provide a kind of bushing for roll, to solve problems faced in current industry.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of bushing for roll, is provided with roll.
As preferably, described roll is provided with roller core and is socketed on the roller shell outside described roller core, and the outer sheath of described roller shell is connected to bushing.
As preferably, described bushing be the cylindrical structural of inner hollow, described bushing inner side is provided with multiple groove.
As preferably, described groove is arc-shaped structure, in described groove, it is provided with multiple joint strip.
As preferably, described bushing and described roller shell is shrink-fit.
As preferably, described bushing material is 42CrMo or 42Cr.
As preferably, the quantity of described groove is 32.
Compared with prior art, usefulness of the present utility model is: be provided with roll, described roll is provided with roller core and roller shell, outer sheath at roller shell is connected to bushing, described bushing in be provided with multiple groove, in groove, be provided with multiple joint strip, the utility model structure is simple, easy to operate, cost is lower.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is illustrated further.
Fig. 1 is sectional view of the present utility model.
In figure: 1, roll; 2, roller core; 3, roller shell; 4, bushing; 5, groove; 6, joint strip.
Embodiment:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail: bushing for roll of a kind of according to Fig. 1, is provided with roll 1, and described roll 1 is provided with roller core 2 and is socketed on the roller shell 3 outside described roller core 2.
Further, the outer sheath of described roller shell 3 is connected to bushing 4, and described bushing 4 is the cylindrical structural of inner hollow.
Again further, the described inner side of bushing 4 is provided with multiple groove 5, and described groove 5 is arc-shaped structure, and described groove 5 li is provided with multiple joint strip 6.
Further, described bushing 4 and described roller shell 3 be shrink-fit.
Again further, the described material of bushing 4 is 42CrMo or 42Cr.
Again further, the quantity of described groove 5 is 32.
During use, it is provided with roll 1, the roller shell 3 that described roll 1 is provided with roller core 2 and is socketed on described roller core 2, described roller shell 3 is provided with bushing 4, described bushing 4 and described roller shell 3 be shrink-fit, on bushing 4, be provided with multiple groove 5, multiple joint strip 6 it is provided with in described groove 5, roll 1 drives bushing 4 to rotate and uses, and when after bushing 4 surface abrasions, changes bushing 4.
It is emphasized that: be only better embodiment of the present utility model above, not the utility model is done any restriction in form, every any simple modification, equivalent variations and modification above embodiment done according to technical spirit of the present utility model, all still belongs in the scope of technical solutions of the utility model.
