Description
Technical field
The utility model relates to field of bearings, relates in particular to a kind of backing roller bearing.
Background technique
Bearing is as basic mechanical parts, every kind of bearing has different functions in use, for example axial load resistant, anti-radial load or anti-axial-radial connected load, or sliding friction is changed into rolling friction, people need to select size and the type of bearing according to different working environments.Back lining bearing is as using a kind of bearing widely, through being usually used on the work roll of cold rolling mill, straightening machine, certainly also for other occasion.But it is thick especially that the problem of existing back lining bearing is outer ring rolling bearing, on for work roll time, pressure on work roll is delivered to support roll by intermediate roll and with this work, it cannot keep enough precision, working life is short, and this has all seriously restricted the working efficiency that uses the relevant device of back lining bearing.
Model utility content
In order to address the above problem, the utility model provides a kind of backing roller bearing, and it has higher bearing accuracy and working life.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of backing roller bearing, comprise outer ring, inner ring, it also comprises three-row cylindrical roller, septum primum circle, septum secundum circle, the first retainer, the second retainer, back-up ring, between described outer ring and inner ring, form cylindrical raceway, described cylindrical raceway is corresponding with the shape of cylindrical roller, described three-row cylindrical roller is arranged in order along outer ring parallel to an axis line direction, first row cylindrical roller and secondary series cylindrical roller are installed in described cylindrical raceway by the first retainer, three-row cylindrical roller is installed in described cylindrical raceway by the second retainer, between described first row cylindrical roller and secondary series cylindrical roller, be provided with septum primum circle, between described secondary series cylindrical roller and three-row cylindrical roller, be provided with spacer ring in secondary series, the both ends of the surface of described inner ring are equipped with back-up ring.
Between described outer ring both ends of the surface and described back-up ring, be provided with Sealing.
The inner side of described back-up ring is along the circumferential direction provided with annular groove, in described annular groove, is provided with seal ring.
Described the first retainer comprises retaining plate, boss, and described retaining plate two sides is equipped with several described boss, forms the slot rolling of accommodating cylindrical roller between adjacent two described boss.
The several described boss on described the first retainer two sides is interspersed.
Described boss is cuboid.
Described the second retainer comprises retaining plate, boss, and described retaining plate one side is equipped with several described boss, forms the slot rolling of accommodating cylindrical roller between adjacent two described boss.
Owing to thering is said structure, the utlity model has following advantage:
1, the utility model backing roller bearing, the close structure of its outer ring, roller and inner ring, bearing accuracy is higher.
2, the utility model backing roller bearing, each component sealing is better, and working life is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model backing roller bearing.
Fig. 2 is the structural representation of the first retainer.
Fig. 3 is the structural representation of the second retainer.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail, to understand better the utility model:
As shown in Figure 1, the backing roller bearing that the utility model provides, the raceway face that outer ring 1 and inner ring 2 form is barrel surface, described cylindrical raceway is corresponding with the shape of cylindrical roller, the internal diameter that is preferably cylindrical raceway is slightly larger than or equals the external diameter of cylindrical roller, be as the criterion to guarantee that cylindrical roller rolls flexibly and don't can be shifted, , in the cylindrical raceway of outer ring and inner ring formation, be arranged in order and be equiped with first row cylindrical roller 3 along outer ring parallel to an axis line direction, secondary series cylindrical roller 4 and three-row cylindrical roller 5, first row cylindrical roller 3 and secondary series cylindrical roller 4 are supported and are located by the first retainer 6 being installed in raceway, three-row cylindrical roller 5 is supported and is located by the second retainer 7 being installed in raceway, between first row cylindrical roller 3 and secondary series cylindrical roller 4, septum primum circle 8 is set, between secondary series cylindrical roller 4 and three-row cylindrical roller 5, septum secundum circle 9 is set, the both ends of the surface of described inner ring 2 are equipped with back-up ring 10.Closely, bearing accuracy is higher, is also difficult for breaking down with the simple in structure, overall of inner ring 2 and three-row cylindrical roller 3,4,5 in the outer ring 1 of the backing roller bearing of this structure.
Described cylindrical roller both ends of the surface center can also have depression, and depression can reduce the stress concentration phenomenon at cylindrical roller edge, extends the working life of cylindrical roller.
More can be by Sealing 11 being set between described outer ring 1 both ends of the surface and described back-up ring 10; Annular groove 12 is along the circumferential direction offered in inner side at described back-up ring 10, and improves the sealability of bearing in the interior mode that seal ring 13 is set of described annular groove 12.
As shown in Figure 2, described the first retainer 6 comprises retaining plate 14, boss 15, the upper and lower surface of described retaining plate 14 is equipped with several described boss 15, between adjacent two described boss 15, form the slot rolling 16 of accommodating cylindrical roller, first row cylindrical roller 3 is installed in superincumbent several slot rolling 16 successively, secondary series cylindrical roller 4 is arranged in several slot rollings 16 below successively, and first row cylindrical roller 3 just contacts outer ring 1 inwall.As shown in Figure 3, described the second retainer 7 also comprises retaining plate 14, boss 15, and these boss 15, the three-row cylindrical rollers 5 that arrange above of retaining plate 14 are arranged in several slot rollings 16 that these boss 15 form.Boss 15 can be selected according to the shape of roller, is cuboid in the present embodiment.
Described retaining plate 14 and boss 15 are preferably one-body molded, in order to save space and to reduce difficulty of processing, between the several boss 15 above described the first retainer 6 and several boss 15 below, are interspersed.
