Description
Technical field
The utility model relates to a kind of bearing fixing device, particularly relates to a kind of bearing fixing device for pipe mill, belongs to field of mechanical technique.
Background technology
Two-roller skew-rolling seamless steel tube rolling mill, its plug is arranged on limiting bogie by bearing, and bearing carries out axial restraint, in the operation of rolling, can produce an impulsive force backward when roll sent into by hollow billet by plug, and powerful impact reduces the service life of bearing.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of rational in infrastructure, simple and practical pipe mill bearing fixing device.
For solving this technical problem, the utility model provides a kind of pipe mill bearing fixing device, comprise plug, axle sleeve, bearing and locking nut, plug is arranged on limiting bogie by bearing, bearing inner race carries out axial restraint by axle sleeve and locking nut, between bearing and limiting bogie, be provided with spacer sleeve and spring base, described spacer sleeve is between bearing outer ring and spring base; Described spring base comprises support, pressing plate, spring and bolt, is sleeved on plug inside described support, and two ends, outside are provided with pressing plate, is provided with multiple spring between two pressing plates, and spring is bolted between two pressing plates.
Described spring is provided with 4-8 root, is evenly distributed on pressing plate circumferentially.
Beneficial effect: the reverse impact produced in the operation of rolling is passed to bearing by plug by the utility model, bearing passes to spring base by spacer sleeve, spring-compressed makes bearing be cushioned; after rolling completes; bearing resets under the action of the spring; thus effectively protect bearing; the utility model has the advantage that structure is simple, be easy to adjustment and safeguard; economize on resources, be conducive to enhancing productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model spring base.
In figure: 1 plug, 2 axle sleeves, 3 bearings, 4 limiting bogies, 5 locking nuts, 6 spacer sleeves, 7 spring bases, 8 pressing plates, 9 springs, 10 supports, 11 bolts.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is specifically described.
Figure 1 shows that structural representation of the present utility model.
The utility model comprises plug 1, axle sleeve 2, bearing 3 and locking nut 5, and plug 1 is arranged on limiting bogie 4 by bearing 3, and bearing 3 inner ring carries out axial restraint by axle sleeve 2 and locking nut 5.
Spacer sleeve 6 and spring base 7 is provided with between described bearing 3 and limiting bogie 4.
Described spacer sleeve 6 is between bearing 3 outer ring and spring base 7.
Figure 2 shows that the structural representation of the utility model spring base.
Described spring base 7 comprises support 10, pressing plate 8, spring 9 and bolt 11, and be sleeved on inside described support 10 on plug 1, two ends, outside are provided with pressing plate 8, is provided with multiple spring 9 between two pressing plates 8, and spring 9 is connected between two pressing plates 8 by bolt 11.
Described spring 9 is provided with 4-8 root, is evenly distributed on pressing plate 8 circumferentially.
Operation principle of the present utility model and the course of work:
During utility model works, plug 1 drives hollow billet to enter roll, and the reverse impact produced in the operation of rolling passes to bearing 3 by plug 1, and bearing 3 passes to the pressing plate 8 of spring base 7 by spacer sleeve 6, and spring 9 is compressed by pressing plate 8, and bearing 3 is cushioned; After rolling completes, under the effect of spring 9, bearing 1 resets, thus effectively protects bearing 1.
The reverse impact produced in the operation of rolling is passed to spring base by plug by the utility model, and spring-compressed makes bearing be cushioned, and has the advantage that structure is simple, be easy to adjustment and safeguard, economizes on resources, be conducive to enhancing productivity.
The above-mentioned embodiment of the utility model, just illustrates, is not only, and all changes within the scope of the utility model or in equivalent scope of the present utility model are all surrounded by the utility model.
