SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a take wheel hub bearing assembly of blowdown water structure is provided, can automatic discharge after making sewage get into, reduce foreign matters such as external dust, mud and get into inside the bearing from the sealing washer, can effectively prolong the performance of this department's sealing washer effect, improve the bearing life-span.

The utility model provides a technical scheme that technical problem adopted is: the utility model provides a take hub bearing assembly of blowdown water structure, includes outer lane, inner circle, dabber, holder, roller and sealing member, tip sets up a drainage lid in the outer lane, the drainage lid includes the go-between that cup joints with the outer lane matching, be equipped with drainage channel in the go-between, still be equipped with external drainage groove on the go-between, drainage channel links up the circulation with the drainage groove.

Preferably, the drainage channel is an annular groove.

Preferably, the inner ring includes an inner ring a and an inner ring B.

Preferably, the sealing element comprises a sealing ring A and a sealing ring B.

The utility model discloses can not only protect the inside lubricated state of bearing not destroyed, can effectively prolong the performance of this department's sealing washer effect moreover, improve the bearing life-span, solved in the past the bearing because foreign matters such as muddy water get into early and lead to the problem of inefficacy.

The utility model has the advantages that the drainage cover is arranged on the inner end surface of the outer ring, so that sewage can be automatically discharged after entering, foreign matters such as external dust and mud can be prevented from entering the bearing from the sealing ring, the function of the sealing ring can be effectively improved, and the service life of the bearing is prolonged.

Detailed Description

The hub bearing assembly with the sewage draining structure comprises an outer ring 1, an inner ring, a mandrel 3, a retainer 5, a roller 6 and a sealing element, wherein the outer ring 1 is provided with two channels on a part in a turning mode, and the outer ring is used as a base body for bearing and rotating the roller through local induction quenching, grinding and superfinishing; the inner ring, the outer ring 1 and the roller 6 are combined to form a bearing and rotating component; the mandrel 3 is a complete bearing rotating part formed by combining the outer diameter, the inner ring and the outer ring roller and is fixed by the interference fit of the outer diameter and the inner diameter of the mandrel; the retainer 5 guides the rollers to rotate; the roller 6 bears and rotates; the sealing ring plays a role in sealing. The end sets up a drainage lid 7 in outer lane 1, plays the sewage effect, drainage lid 7 includes the go-between 10 that cup joints with 1 matches in outer lane, be equipped with drainage channel 11 in the go-between, drainage channel 11 is the ring channel. An external drainage groove 12 is further formed in the connecting ring 10, the drainage channel 11 is communicated with the drainage groove 12, and muddy water flows into the drainage groove 12 through the annular groove drainage channel 11 and then is discharged. Wherein the inner ring comprises an inner ring A2 and an inner ring B8; the sealing element comprises a sealing ring A4 and a sealing ring B9.

During installation, the 46 rollers 6 are evenly arranged in the two retainers 5, the inner rings A2 and B8 are respectively pressed into the retainers 5, grease is respectively injected, the rollers are respectively arranged in the two roller paths of the outer ring 1, the sealing ring B9 is pressed into the outer ring 1 by a hydraulic machine, the drainage cover 7 is pressed into the outer ring 1, the inner rings A2 and B8 are pressed on the mandrel 3, the sealing ring A4 is pressed into the inner rings and the outer rings by the hydraulic machine, and the flanging at the end part of the mandrel 3 is pressed against the inner ring A2 by the flanging machine, so that the product installation is completed.

As shown in figure 6, the hub bearing is installed in the steering knuckle 13, the drainage groove 12 penetrates through the steering knuckle hole, and when the hub bearing is installed, the drainage groove 12 is fixed downwards, so that muddy water can be conveniently discharged.

The structure function completely meets the requirements on use, and the whole structure is optimally designed. The utility model discloses a structural design of sewage system is arranged in the area, and this structure is through mud salt water splash test, and inside bearing outside sealing washer department did not have muddy water and got into the bearing for the great improvement in life-span of bearing, the utility model has the characteristics of compact structure, simple to operate, superior performance etc.
