Abstract
The utility model discloses a sealed self-aligning ball bearing which comprises an outer ring, an inner ring and steel balls arranged in a holder, and also comprises seal structures which are arranged between the outer ring and the inner ring and are arranged at both sides of the steel balls. The seal structures comprise dust covers and seal rings which are connected to the dust covers and are connected to the inner ring. Compared with the prior art, the sealed self-aligning ball bearing has the advantages that the sealing performance of the self-aligning ball bearing is greatly improved through the additional arrangement of the seal structures which consist of the dust covers and the seal rings and can avoid invasion of external sundries and can prevent leakage of lubricating grease, so that the early failure of the bearing when working at the high dust environment is eradicated effectively, the flexibility and the stability of rotary motion of the bearing during use are improved, the failure rate of the bearing is reduced, and the working life of the bearing is prolonged greatly.
Description
Technical field
The utility model relates to a kind of sealing selfaligning ball bearing.
Background technique
Selfaligning ball bearing generally seldom uses dust cover or seal ring, but under some special operation conditions, under working environment as high dust, also sealability there is very high requirement when requiring bearing to adopt dust cover, single use metal dust-proof cover or use rubber seal all can not satisfy usage requirement fully, can not prevent that outside foreign material from entering in bearing, easily cause the early failue of bearing, thus the flexibility, the stationarity that affect the working life of bearing and in use rotate.
The model utility content
What technical problem to be solved in the utility model was to provide a kind of good seal performance can prevent the sealing selfaligning ball bearing that outside foreign material enter.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of sealing selfaligning ball bearing, the steel ball that it comprises outer ring, inner ring and is arranged in retainer, also comprise being located at sealing configuration between described outer ring and inner ring and that be positioned at described steel ball both sides, the sealing structure comprises the dust cover that is connected with the outer ring and is connected to seal ring on dust cover and that be tightly connected with inner ring.
The outward edge of described dust cover is the crimping of hook solid, is provided with to allow the draw-in groove of the annular that the crimping of dust cover snaps on the inner peripheral surface of described outer ring.
The position that is tightly connected with described inner ring on described seal ring has two lip limits of radially extending along inner ring, and the length on lateral lip limit is greater than the length on medial lip limit, also is being provided with annular groove on seal ring between two lip limits.
Described dust cover is connected with described seal ring is bonding.
The utility model adopts technique scheme, compared with prior art, this selfaligning ball bearing is by setting up the sealing configuration that is made of dust cover and seal ring, this sealing configuration both can prevent outside foreign material intrusion bearing, can prevent the leakage of lubricating grease again, the sealability of bearing reaches greatly and improves, thereby effectively stopped the early failue that bearing is worked under high dust atmosphere, the flexibility that bearing in use rotates, stationarity have been improved, reduce the rate of fault of bearing, greatly improved the working life of bearing.
Description of drawings
Fig. 1 is the sectional view of selfaligning ball bearing of the present utility model;
Fig. 2 is the sectional view of the sealing configuration of selfaligning ball bearing of the present utility model;
Mark in above-mentioned figure is: 1, outer ring; 2, inner ring; 3, retainer; 4, steel ball; 5, dust cover; 6, seal ring; 7, crimping; 8, lateral lip limit; 9, medial lip limit; 10, annular groove.
Embodiment
Be illustrated in figure 1 as a kind of sealing selfaligning ball bearing of the present utility model, it comprise outer ring 1, inner ring 2, the steel ball in retainer 34 and be located at outer ring 1 and inner ring 2 between and the sealing configuration that is positioned at steel ball 4 both sides, as shown in Figure 2, the sealing structure comprises the dust cover 5 that is connected with outer ring 1 and is connected to seal ring 6 on dust cover 5 and that be tightly connected with inner ring 2.
As shown in Figure 2, the outward edge of dust cover 5 is the crimping 7 of hook solid, and dust cover 5 is made by mild-carbon steel strip, as shown in Figure 1, is provided with on the inner peripheral surface of outer ring 1 and allows the draw-in groove of the annular that the crimping 7 of dust cover 5 snaps in.
As shown in Figure 2, the position that is tightly connected with inner ring 2 on seal ring 6 has two lip limits of radially extending along inner ring 2, and the length on lateral lip limit 8 is greater than the length on medial lip limit 9, also be provided with annular groove 10 on seal ring 6 between two lip limits, two lip limits of seal ring 6 inner radius are designed to " Jiong " type step structure, make its lip limit and inner ring 2 form labyrinth sealings.Dust cover 5 is connected with seal ring 6 is bonding, and seal ring 6 adopts quality of rubber materials to make.
This selfaligning ball bearing is by setting up the sealing configuration that is made of dust cover 5 and seal ring 6, this sealing configuration both can prevent outside foreign material intrusion bearing, can prevent the leakage of lubricating grease again, the sealability of bearing reaches greatly and improves, thereby effectively stopped the early failue that bearing is worked under high dust atmosphere, improve the flexibility that bearing in use rotates, stationarity, reduced the rate of fault of bearing, the working life of greatly having improved bearing.
The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or without improving, design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
