Abstract
Disclosed is a novel conical roller wheel hub bearing unit which mainly comprises an inner ring, an upper seal ring, a roller, a nylon retainer, an outer flange ring, a lower seal ring, an inner flange ring and a knurled bolt, and is characterized in that two conical roller channels are respectively arranged on the inner circle of the outer flange ring; conical roller channels are respectively arranged on the outer circle of the inner ring and the outer circle of the inner flange ring corresponding to the conical roller channels on the outer flange ring; a retainer provided with conical rollers is respectively mounted in the roller channels; the inner ring is nested in the concave groove on the outer circle of one end of the inner flange ring; a conical roller channel is arranged on the outer circle of the inner ring; two inner rings in the prior art are reduced to one inner ring; the conical roller channels are directly arranged on the inner flange ring; the product structure is simplified, and the product accuracy and service life are improved; the product noise is reduced, and the production cost is saved.
Description
Technical field:
The utility model relates to the automobile hub bearing technical field, specifically a kind of new taper roller hub-bearing unit.
Background technology
Existing taper roller hub-bearing unit, its structure is that the double-row roller bearing that will include an outer ring and two inner rings is pressed onto on the inner flange, because parts are more, complex structure, in the process of assembling, easily deform, cause the decline of product strength and running accuracy, cause the noise of coro bearng hub and vibrations bigger.
Invention is inner to be held
In order to overcome disadvantages of background technology, the utility model provides a kind of simple in structure, easy to assembly, intensity and all higher taper roller hub-bearing unit of precision, and this hub-bearing unit has reduced productive costs, has improved work efficiency.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of new taper roller hub-bearing unit is made of inner ring, back seal circle, roller, nylon cages, outward flange dish, lower seal, inner flange and knurled nut; It is characterized in that: circle being provided with two circular cone raceways in the flange outside, and also establishes the circular cone raceway respectively on the corresponding inner ring cylindrical of outward flange dish circular cone raceway He on the inner flange cylindrical; After successively taper roller being installed on two retainers respectively, and be assembled in the raceway respectively.
Inner ring described in the utility model is sleeved in the groove on the inner flange one end cylindrical, the retainer that taper roller is housed is contained in the raceway of establishing between the circle in inner ring cylindrical and the outward flange dish; The another retainer that taper roller is housed, be installed in the raceway of establishing between the circle in inner flange cylindrical and the outward flange dish then; Upper and lower seal ring is installed in respectively on inside and outside flange and outward flange dish and the inner ring termination.
The beneficial effects of the utility model are: a kind of new taper roller hub-bearing unit, originally two inner rings setting are reduced to one, tapered roller raceway is directly arranged on the inner flange, simplified product structure, product precision and service life have been improved, reduce the product noise, saved cost.
