Abstract
The utility model relates to a backing bearing which comprises a bearing outer ring and a bearing inner ring that correspond to each other, wherein the middle part of the bearing outer ring is provided with a middle flange; two ends of the bearing inner ring are provided with outer flanges; a roller is arranged between the bearing outer ring and the bearing inner ring, and is provided with a retainer; two ends of the roller are provided with sealing rings; the outer sides of the sealing rings are provided with spring check rings; and dustproof covers are arranged between the spring check rings and the outer flanges. The backing bearing has the benefits that the dustproof covers and the sealing rings are arranged in a staggered way, so that labyrinth seal structures are formed at two ends of the bearing, therefore, on one hand, the dust can be effectively prevented from entering into the bearing to influence the accuracy and the service life of the bearing, on the other hand, a lubricating agent can be effectively stored in the bearing, so that the lubricating effect is improved, and the leakage of the lubricating agent is reduced.
Description
Technical field
The utility model relates to field of mechanical technique, relates in particular to a kind of back lining bearing.
Background technique
Back lining bearing is the thick especially rolling bearing in outer ring, generally is used for multiple rollers cold calender equipment, also can be used for other occasions, for example straightening machine.Main structural type is biserial or three-row cylindrical roller bearing, is with retainer or is not with the full roller of retainer, and inner ring has one or multi-channel circular groove and several oilholes.Because present back lining bearing all is not with seal arrangement, cause the waste of lubricant oil on the one hand, because the leakage of lubricant oil might cause the pollution to the rolled steel limit, influence quality of product on the other hand.
The model utility content
The purpose of this utility model provides a kind of back lining bearing, can prevent effectively that dust from entering in the bearing, saves bearing lubricant simultaneously, to overcome present prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of back lining bearing, the bearing outer ring and the bearing inner race that comprise mutual correspondence, the middle part of described bearing outer ring is provided with centre rib, the two ends of bearing inner race are provided with outer rib, be provided with roller between bearing outer ring and the bearing inner race, roller is provided with retainer, and the two ends of roller are equipped with seal ring, the outside of seal ring is provided with check ring, is provided with dust cover between check ring and the outer rib.
The beneficial effects of the utility model are: increased dust cover and seal ring at the bearing two ends, because the endoporus of dust cover matches with the periphery of bearing inner race, the cylindrical of dust cover and bearing outer ring endoporus leave the gap, and the cylindrical of seal ring matches with the bearing outer ring endoporus, and the endoporus and the bearing inner race of seal ring are gapped.Dust cover and seal ring are interconnected, so just formed labyrinth seal structure at the bearing two ends, can prevent effectively that dust from entering in the bearing on the one hand, influence the precision and the working life of bearing, on the other hand, oiling agent is kept in the bearing, has improved lubrication effect, reduce the leakage of oiling agent simultaneously.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the sectional view of the described a kind of back lining bearing of the utility model embodiment.
Among the figure:
1, bearing outer ring; 2, bearing inner race; 3, centre rib; 4, outer rib; 5, roller; 6, retainer; 7, seal ring; 8, check ring; 9, dust cover.
Embodiment
As shown in Figure 1, the described a kind of back lining bearing of the utility model embodiment, the bearing outer ring 1 and the bearing inner race 2 that comprise mutual correspondence, the middle part of described bearing outer ring 1 is provided with centre rib 3, and the two ends of bearing inner race 2 are provided with outer rib 4, is provided with roller 5 between bearing outer ring 1 and the bearing inner race 2, roller 5 is provided with retainer 6, the two ends of roller 5 are equipped with seal ring 7, and the outside of seal ring 7 is provided with check ring 8, are provided with dust cover 9 between check ring 8 and the outer rib 4.
Dust cover 9 and seal ring 7 have been increased at the bearing two ends, because the endoporus of dust cover 9 matches with the periphery of bearing inner race 2, the cylindrical of dust cover 9 and bearing outer ring 1 endoporus leave the gap, and the cylindrical of seal ring 7 matches with bearing outer ring 1 endoporus, and the endoporus of seal ring 7 and bearing inner race 2 are gapped.Dust cover and seal ring 7 are interconnected, so just formed labyrinth seal structure at the bearing two ends, can prevent effectively that dust from entering in the bearing on the one hand, influence the precision and the working life of bearing, on the other hand, oiling agent is kept in the bearing, has improved lubrication effect, reduce the leakage of oiling agent simultaneously.
