Abstract
The utility model discloses an automobile hub bearing. The automobile hub bearing comprises a bearing outer ring, a bearing inner ring and steel balls, wherein the steel balls are arranged between the bearing outer ring and the bearing inner ring; a sealing groove is formed in each of the external and internal walls of the bearing outer ring; the sealing groove in the external wall is in tight fit with a dustproof cover; the sealing groove in the internal wall is in interference fit with a sealing ring; the sealing ring is a double-lip sealing ring; an elastic groove is formed in an outer lip of the sealing ring. According to the automobile hub bearing, the dustproof cover is in tight fit with the sealing groove, so that the dustproof cover is effectively prevented from loosening or falling off; the sealing ring is the double-lip sealing ring, and the elastic groove is formed in the outer lip, so that the contact between the sealing ring and the bearing outer ring of the bearing is adjusted automatically during rotation, foreign matters, such as silt, dust and the like, can be effectively prevented from entering the interior of the bearing, and the sealing performance of the bearing is improved.
Description
Technical field
The utility model relates to a kind of bearing, relates in particular to a kind of automobile hub bearing.
Background technique
Automobile hub bearing is the important spare part for the automotive wheel part.And automobile is worked often in vibration environment, hub bearing, due to long vibration, causes the bad connection of seal ring and the inside and outside circle of bearing, causes the foreign material such as silt, dust to enter in bearing, make the hub bearing seal failure, thereby greatly shortened the working life of bearing.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of automobile hub bearing is provided, and can not only effectively prevent the loosening of dust cover or fall lid, can also effectively prevent that the foreign material such as silt, dust from entering bearing inside, has improved the sealing of bearing.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs:
A kind of automobile hub bearing, comprise bearing outer ring, bearing inner race and be arranged on bearing outer ring and bearing inner race between steel ball, be respectively arranged with a seal groove on described bearing outer ring outer wall and inwall, seal groove on outer wall and dust cover close-fitting, seal groove on inwall and seal ring interference fit, described seal ring is double-lip sealing ring, and the outer lip of seal ring is provided with elastic groove.
The beneficial effect the utlity model has: by the design of dust cover and seal groove close-fitting, effectively prevented the loosening of dust cover or fallen lid; Seal ring is double-lip sealing ring, and the outer lip place is provided with elastic groove, makes bearing automatically regulate the Exposure of seal ring and bearing outer ring in rotation process, can effectively prevent that the foreign material such as silt, dust from entering bearing inside, has improved the sealing of bearing.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the ring structure schematic diagram.
In figure: bearing outer ring 1, bearing inner race 2, steel ball 3, seal groove 4, dust cover 5, seal ring 6, elastic groove 7.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of automobile hub bearing, comprise bearing outer ring 1, bearing inner race 2 and be arranged on bearing outer ring 1 and bearing inner race 2 between steel ball 3, be respectively arranged with a seal groove 4 on described bearing outer ring 1 outer wall and inwall, seal groove 4 and dust cover 5 close-fittings on outer wall, seal groove 4 and seal ring 6 interference fit on inwall, described seal ring 6 is double-lip sealing ring, the outer lip of seal ring 6 is provided with elastic groove 7.
The utility model is the design with seal groove 4 close-fittings by dust cover 5, has effectively prevented the loosening of dust cover 5 or has fallen lid; Seal ring 6 is double-lip sealing ring, and the outer lip place is provided with elastic groove 7, make bearing automatically regulate the Exposure of seal ring 6 and bearing outer ring 1 in rotation process, can effectively prevent that the foreign material such as silt, dust from entering bearing inside, improve the sealing of bearing, extended the sealing life of bearing.
