Description
Technical field
The utility model relates to heavy-duty commercial vehicle rear wheel hub bearing field, in particular to a kind of wide rib internal-and external diameter is salable
Long-life commercial vehicle hub bearing.
Background technique
Hub bearing refers to and provides accurately guide zero applied to load-bearing at Automobile shaft and for the rotation of wheel hub
Part is the important component of carload and rotation；Existing heavy-duty commercial vehicle rear wheel hub bearing exists centainly when in use
The drawbacks of, traditional commercial vehicle rear wheel hub bearing be with common single-row tapered roller bearing, rib thickness in 6~8mm, by
It is narrow in the rib of ordinary conical roller bearing, can not mounting framework sealing ring, but individually add a steel in rib outer end
Liquefaction seal ring, because this oil seal ring outer diameter cannot be coaxial with the realization of the inner ring raceway of bearing, work a period of time will be quickly damaged
Framework type sealing ring leads to its loss of seal effect, is not carried out effective sealing, causes the lubricating grease of bearing working chamber excessive
It is lost, causes the unlubricated state in bearing working surface, cause bearing initial failure, further, since it is not carried out effective sealing,
So that the dust particles outside wheel hub cavity and other dirts is entered bearing working surface, exacerbate bearing wear, causes bearing life big
Amplitude reduction, individually plus steel oil seal ring increase the volume and weight of wheel hub, increase the oil consumption of commercial vehicle, reduce use
The economic benefit at family brings certain influence to the use of heavy-duty commercial vehicle rear wheel hub bearing, for this purpose, it is proposed that a kind of width
The salable long-life commercial vehicle hub bearing of rib internal-and external diameter.
Utility model content
The main purpose of the utility model is to provide a kind of salable long-life commercial wheel hub axles of wide rib internal-and external diameter
It holds, can effectively solve the problems in background technique.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of salable long-life commercial vehicle hub bearing of width rib internal-and external diameter, including rolling element, it is characterised in that: described
The outer surface of rolling element is fixedly installed with outer ring, and the inner surface of rolling element is fixedly installed with bearing inner race, the outer ring it is interior
Retainer is fixedly installed between surface and the outer surface of rolling element, the rib of the bearing inner race is designed as wide rib, and axis
The side external surface for holding inner ring is fixedly installed with framework type sealing ring, the outer surface of the inner surface of the outer ring and bearing inner race it
Between be equipped with hub bearing working chamber, O-ring seal or empty knife structure are equipped at the basal plane chamfering of the bearing inner race.
Preferably, the rib width of the bearing inner race is widened to 18.52mm by original 7.52mm.
Preferably, the width of the bearing inner race is widened to 58mm by 47mm.
Preferably, the rib external diameter surface roughness value of the bearing inner race is changed to 0.4 by original 5.
Preferably, the basal plane inner chamfer inside the hub bearing working chamber is changed to that O can be inlayed by original arc chord angle
Type sealing ring or empty knife structure.
Compared with prior art, the utility model has the following beneficial effects: the width rib internal-and external diameter salable long-life
Commercial vehicle hub bearing can be allowed wheel hub cavity inner bearing lubricating grease not excessive, obtain hub bearing using framework type sealing ring
Effectively sealing, the dust particles and other dirts allowed outside wheel hub cavity cannot be introduced into wheel hub working chamber, avoid because of bearing working surface
The bearing initial failure of abrasion and appearance, and internal diameter increases O-ring seal, promotes bearing life significantly, can reduce quotient
With the volume and weight of wheel hub, the lightweight of hub unit is realized, to improve the specified mounted mass of commercial vehicle, increase user
Economic benefit, entire bearing arrangement is simple, and easy to operate, the effect used is more preferable relative to traditional approach.
