Abstract
The utility model discloses a structure for preventing an outer ring of a bearing in a hub from rotating. The bearing is press-mounted in a bearing baffle of the hub; an outer half-cylinder hole is formed in the inner wall of the bearing baffle of the hub; an inner half-cylinder hole is formed in the outer wall of the outer ring of the bearing; the outer half-cylinder hole and the inner half-cylinder hole are combined to form a locating pin hole; a locating pin is press-mounted in the locating pin hole. The structure is simple in structure and low in manufacturing cost, the locating pin used for preventing the outer ring of the bearing from rotating is additionally arranged on the joint surface of the outer ring of the common bearing and the hub, so that the hub and the outer ring of the bearing are integrated into a whole, and the outer ring of the bearing can rotate under the condition of bearing heavy load. According to the utility model, market batch breakdown can be solved under the condition of little cost increment, the service life of a common hub shaft can be prolonged, and the added cost when a hub bearing unit is adopted can be reduced.
Description
Technical field
The utility model relates to automotive hub field, specifically a kind of structure that prevents hub inner bearing outer ring rotating.
Background technique
In Chinese market, because heavy truck deadweight tonnage is larger, work condition environment is severe at present, cause the bearing outer ring rotation phenomenon in the wheel hub of market more and more, and maintenance cost is relatively high.Although many heavy cards progressively replace plain bearing with hub-bearing unit, can effectively prevent that hub bearing from walking outer ring, but hub-bearing unit cost is higher, and follow-up maintenance difficulty, for the moment can't replace in enormous quantities plain bearing to use on market, especially heavily block market.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of structure that prevents hub inner bearing outer ring rotating, adopts locating stud that wheel hub and inner bearing outer ring are carried out to locked location, effectively prevents that the outer ring of hub inner bearing from rotating under heavily loaded pressure.
The technical solution of the utility model is:
A kind of structure that prevents hub inner bearing outer ring rotating, pressing bearing in the bearing gear of described wheel hub, it is characterized in that: on the bearing retaining inner wall of described wheel hub, be provided with outer semicylindrical opening, on the outer wall of bearing outer ring, be provided with interior semicylindrical opening, described outer semicylindrical opening and interior semicylindrical opening are combined to form positioning pin hole, are pressed with locating stud in positioning pin hole.
Described positioning pin hole is one group, is uniformly distributed along the outer ring of bearing.
Described positioning pin hole is three, is uniformly distributed along the outer ring of bearing.
Advantage of the present utility model:
The utility model is simple in structure, fabricating cost is low, increases by one and prevent the locating stud that bearing outer ring rotates on common bearing outer ring and wheel hub faying surface, and wheel hub and bearing outer ring are become one, and prevents that bearing outer ring from rotating under case of heavy load being subject to; The utility model can solve market fault in batches increasing in a small amount of cost situation, can extend common hub spindle working life, also can reduce the expense that uses hub-bearing unit to increase.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1, a kind of structure that prevents hub inner bearing outer ring rotating, pressing bearing 2 in the bearing gear of wheel hub 1, on the bearing retaining inner wall of wheel hub 1, be provided with outer semicylindrical opening, on the outer wall of bearing 2 outer rings, be provided with interior semicylindrical opening, outer semicylindrical opening and interior semicylindrical opening are combined to form positioning pin hole, are pressed with locating stud 3 in positioning pin hole; Wherein, positioning pin hole is three, is uniformly distributed along the outer ring of bearing 2.
Claims (3)
1. one kind prevents the structure of hub inner bearing outer ring rotating, pressing bearing in the bearing gear of described wheel hub, it is characterized in that: on the bearing retaining inner wall of described wheel hub, be provided with outer semicylindrical opening, on the outer wall of bearing outer ring, be provided with interior semicylindrical opening, described outer semicylindrical opening and interior semicylindrical opening are combined to form positioning pin hole, are pressed with locating stud in positioning pin hole.
2. a kind of structure that prevents hub inner bearing outer ring rotating according to claim 1, is characterized in that: described positioning pin hole is one group, is uniformly distributed along the outer ring of bearing.
