Abstract
The utility model belongs to the technical field of bearings, and relates to a four-column roller bearing, which is mainly used in the metallurgical industry as a rolling mill bearing. The roller bearing consists of an outer ring, an inner ring, a roller, a second roller, a retaining rack base, a retaining rack cover, a cotter pin and an outer retainer ring. The employment of the cotter pin, instead of a rivet or a screw, in the connection of the retaining rack base and the retaining rack cover has the effects of simplifying the assembly process, reducing the consumption of electricity during the welding process, and making the use of the bearing safer and more reliable.
Description
Technical field
The utility model belongs to technical field of bearings, and particularly a kind of four-line column roller bearing is mainly used in the roller-mill bearing of metallurgy industry.
Background technique
At present, connect by rivet mostly between the maintenance stand of four-line column roller bearing and the retainer lid, if but the pocket hole is long, and then rivet hole is long, has strengthened the bore process difficulty, and borehole accuracy also be cannot say for sure to demonstrate,prove, and needs rivet welding, and operation is also complicated; When adopting screw to connect to keep stand and retainer lid, need welding, and bearing may occur welding knurl in the course of the work and peel off, the phenomenon of thread looseness causes connecting not tight.
Summary of the invention
At the deficiency of above technology, the purpose of this utility model is to propose a kind of four-line column roller bearing, solves being connected complex procedures and connecting not tight problem of maintenance stand and retainer lid.
The technical solution of the utility model is: a kind of four-line column roller bearing, comprise outer ring 1, inner ring 2, roller 3, second roller 4, keep stand 5, retainer lid 6, outer back-up ring 8, it also comprises cotter pin 7, keeps stand 5 to be connected with retainer lid 6 by cotter pin 7.
The beneficial effects of the utility model are: adopt cotter pin 7 to replace rivet or screw to connect and keep stand 5 and retainer lid 6, simplified assembly process, reduced power consumption, and the phenomenon of thread looseness has easily taken place when having avoided connecting with screw, more safe and reliable when using bearing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, the outer ring, 2, inner ring, 3, roller, 4, second roller, 5, keep stand, 6, the retainer lid, 7, cotter pin, 8, outer back-up ring.
Embodiment
As shown in Figure 1, the utility model comprises outer ring 1, inner ring 2, roller 3, second roller 4, keeps stand 5, retainer lid 6, cotter pin 7 and outer back-up ring 8, keeps stand 5 to be connected with retainer lid 6 by cotter pin 7.Outer ring 1, roller 3, maintenance stand 5, retainer lid 6 are outer assembly, and inner ring 2 is interchangeable, and outer back-up ring 8 is convenient to install.
