Sealing structure be difficult to meet to require, show as that sealing effectiveness is poor, and lubricating grease is difficult to keep, alien material enters Bearing inner,
Cause bearing initial failure.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of compound sealing device of automobile pressure bearing, should
Compound sealing device changes existing sealing structure, improves the holding situation of bearing grease, effectively avoids foreign matter from invading.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of compound sealing device of automobile pressure bearing, including blowout patche and seat ring, the blowout patche are mutually handed over seat ring
Thread alternating is combined, and at the fastening in the middle part of form cavity, opened gap is formed at both ends, rolling is placed with the cavity
Body, sealing ring is provided with the opened gap.
Deep-slotted chip breaker is equipped with the blowout patche inner surface and race interior surface, the deep-slotted chip breaker is by point or face contact and rolls
Body couples.
The sealing ring is three lip structures, and support frame is provided with inside the sealing ring.
The material of the sealing ring is oil resistant rubber, and the material of the support frame is low-carbon cold rolling steel.
The rolling element is ball, and lubricating grease is evenly distributed with the ball.
The rolling element is made of metal.
The utility model compared with prior art, has an advantageous effect in that：
Blowout patche with seat ring is interlaced snaps together, and the cavity for placing rolling element is formed at middle part, at both ends
Opened gap is formed, sealing ring is provided with opened gap；And using contact lips sides sealing ring, respectively in bearing,
External seal space has carried out effective sealing, and the flood rate of bearing grease substantially reduces, and ensure that the effectively lubricating of bearing.Together
When, more lips design of sealing ring can effectively prevent the harmful substances such as muddy water, dust, the grains of sand from entering Bearing inner, ensure axle
Hold with excellent sealing property, bearing performance is ensured, considerably improve the life and reliability of bearing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the utility model ring structure schematic diagram；
Wherein：1 is blowout patche, and 2 be seat ring, and 3 be cavity, and 4 be upper shed gap, and 5 be under shed gap, and 6 be rolling element, 7
