Background technique
Its sealing configuration of seal deep groove ball bearing of the prior art all is to rely on very big magnitude of interference to play the erosion of sealing muddy water, the bearing of this structure is in the course of the work because friction torque is big, thereby make the temperature rise of bearing too high, thereby have influence on the life-span of bearing, in addition, for the intrusion of muddy water in the course of the work is unavoidable, and the reliability of bearing is low.Mechanically Chang Yong zanjon bearing comprises outer ring and inner ring, between outer ring and the inner ring rolling element is housed, parallel two sealing covers, the inboard drive fit in the outer rim of two sealing covers and outer ring of being stamped on the side of bearing ring.At present, the sealing configuration cost of production is higher, and problems such as sealing cover easily comes off, sealing effect is not good, complex structure, quality instability still exist.
For this reason, people have carried out long-term exploration, have proposed various solutions.Though many schemes have solved short, problem such as reliability is low in existing sealing configuration working life to a certain extent.But ubiquity, and design is reasonable inadequately, cost of production is higher, problems such as sealing cover easily comes off, sealing effect is not good, complex structure, quality instability.
Summary of the invention
The purpose of this utility model is the sealing configuration that a kind of sealing cover difficult drop-off, good sealing effect, simple in structure, zanjon bearing that stability is high are provided at the problems referred to above.
The purpose of this utility model can realize by following technical proposal: a kind of sealing configuration of deep groove ball bearing, comprise bearing inner race, bearing outer ring and at least one lip ring, described Sealing is between bearing inner race and bearing outer ring, the bearing outer ring inboard is provided with and the dustproof groove one of the corresponding annular of Sealing, the outer rim of above-mentioned Sealing is embedded in the dustproof groove one of bearing outer ring, it is characterized in that, the outer rim of described Sealing has circular fold, the outside of described flanging has the projection of several radial protrusions, and the inner edge of described Sealing has seal lip one, seal lip two, seal lip three and seal lip four.
Seal lip four is between seal lip one and seal lip two, and seal lip one is close to seal groove step place; Seal lip two and seal lip four are close to the side of the seal groove of rib with certain elasticity interference; Seal lip three directly forms certain clearance with the seam of the inner ring of rib
In the sealing configuration of above-mentioned deep groove ball bearing, the described bearing inner race outside is provided with and the dustproof groove two of the corresponding annular of Sealing, and the inner edge of above-mentioned Sealing is embedded in the dustproof groove two of bearing inner race.Also fixed installation Sealing difficult drop-off in the dustproof groove two of the inner edge embedding of Sealing.
In the sealing configuration of above-mentioned deep groove ball bearing, described seal lip one is close to dustproof groove two step places, and seal lip two and seal lip four are close to the side of dustproof groove two with certain elasticity interference.The compactness that has guaranteed sealing configuration together that Sealing and two interference of dustproof groove are close to makes it to reach the effect of optimal seal.
In the sealing configuration of above-mentioned deep groove ball bearing, the bottom of the inboard dustproof groove one of described bearing outer ring is provided with depression, and the projection on the described Sealing outer rim flanging is positioned at the depression of inboard dustproof groove one bottom of bearing outer ring.
In the sealing configuration of above-mentioned deep groove ball bearing, described number of slugs is two or more.
In the sealing configuration of above-mentioned deep groove ball bearing, described Sealing has two and bilateral symmetry to be distributed in the bearing two ends.
Compared with prior art, the utility model sealing configuration cost of production is lower, advantage such as sealing cover difficult drop-off, sealing effect are splendid, simple in structure, steady quality.
Description of drawings
Fig. 1 is the sealed structural representation of deep groove ball bearing.
Fig. 2 is the partial enlarged drawing of the sealing configuration of deep groove ball bearing.
Among the figure, 1, bearing inner race; 2, bearing outer ring; 3, Sealing; 4, dustproof groove one; 5, dustproof groove two; 6, projection; 7, seal lip one; 8, seal lip two; 9, seal lip three; 10, seal lip four; 11, depression;
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, the sealing configuration of deep groove ball bearing comprises bearing inner race 1, bearing outer ring 2 and at least one lip ring 3 between bearing inner race 1 and bearing outer ring 2, and bearing inner race 1 outside is provided with and the dustproof groove 25 of Sealing 3 corresponding annulars.Bearing outer ring 2 inboards are provided with and the dustproof groove 1 of Sealing 3 corresponding annulars, and the bottom of inboard dustproof groove 1 is provided with depression 12.
As shown in Figure 2, the outer rim of Sealing 3 has circular fold, and the outside of described flanging has the projection 6 of quantity for two or more radial protrusions.The inner edge of Sealing 3 has seal lip 1, seal lip 28, seal lip 39 and seal lip 4 10.
In the sealing configuration of deep groove ball bearing, two Sealing 3 bilateral symmetry are distributed in the bearing two ends, and the outer rim of Sealing 3 is embedded in the bearing outer ring 2 dustproof grooves 1, and the projection 6 on the outer rim flanging is positioned at the depression 12 of bearing outer ring 2 inboard dustproof groove one 4 bottoms.The inner edge of Sealing 3 is embedded in the bearing inner race 1 dustproof groove 25, the seal lip one 7 of Sealing 3 on above-mentioned Sealing 3 is close to dustproof groove 25 step places, and seal lip 28 and seal lip 4 10 are close to the side of dustproof groove 25 with certain elasticity interference.
