Abstract
The utility model provides a rivet ball hub bearing in terminal surface, characterized by: in riveting bearing inner race the interior circle of outward flange dish, the bearing inner race suit circles in holding, be equipped with corresponding biserial raceway between the outer disc of disc and bearing inner race in the bearing inner race, be equipped with the holder in the biserial raceway respectively, install the steel ball on the holder, the sealing washer is equipped with between the both ends, respectively about the channel in outer disc of bearing inner race and the outer lane between the disc, in riveting bearing inner race the interior circle of outward flange dish, bearing inner race and outward flange dish interference fit, then with the left end head of outward flange dish, the riveting forms on bearing inner race's terminal surface detains the edge in round, form an overall structure with the bearing inner race close control in the outward flange dish, prevent bearing inner race axial displacement. Not only bearing inner race axial displacement can be effectually prevented, hub unit's rigidity can be promoted moreover after the formation wholly, the service life of the hub bearing unit is prolonged.
Description
Technical field
The utility model relates to a kind of hub bearing technology, is riveting ball hub bearing in a kind of end face specifically.
Background technique
Be in existing ball hub bearing as shown in Figure 1 and Figure 2, comprise outward flange dish 1, bearing outer ring 2, retainer 3, back-up ring 4, seal ring 5, bearing inner race 6, during hub bearing work, rely on back-up ring restrictive axes bearing outer-ring to move axially.Must micro-gap be there is due to back-up ring and bearing outer ring end face in this structure, to install back-up ring, a period of time is run at hub bearing, particularly after stand under load, bearing outer ring will produce the wriggling of opposing outer flange dish in wheel hub inside, originally micro-gap can slowly become large along with relative movement, easily makes bearing early failue.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, riveting ball hub bearing in a kind of end face is provided, riveted joint ball hub bearing unit in this modified model end face, effectively can solve existing structure cannot the shortcoming of restrictive axes bearing outer-ring movement completely, outward flange dish and bearing outer ring is made to form entirety, improve hub bearing integral rigidity, prevent bearing outer ring axial displacement to cause early failue problem.
Technical solutions of the utility model are: riveting ball hub bearing in a kind of end face, comprise outward flange dish, bearing outer ring, bearing inner race, retainer, steel ball, right-left seal circle and buckle edge.
Riveting ball hub bearing in described end face: bearing outer ring riveting is entered in the inner circle of outward flange dish, bearing outer ring is sleeved on and holds on inner ring; Be provided with corresponding biserial raceway between bearing outer ring inner headed face with bearing inner race periphery, be respectively equipped with retainer in biserial raceway, retainer is provided with steel ball; Between two ends, raceway groove left and right between bearing inner race periphery and outer ring inner headed face, respectively seal ring is housed.Bearing outer ring riveting is entered in the inner circle of outward flange dish, bearing outer ring and outward flange dish interference fit, then by left end (front end) head of outward flange dish, riveting forms button edge on the end face of bearing outer ring, bearing outer ring is closely controlled outside in flange plate inner circle, form an overall structure, prevent bearing outer ring axial displacement.
The beneficial effects of the utility model are: on existing ball hub bearing architecture basics, remove check ring 4, outward flange dish and bearing outer ring are riveted, form an overall structure, not only effectively can eliminate the axial displacement of bearing, and formed after entirety can the rigidity of lifting wheel hub unit; Improve the working life of hub-bearing unit.
Accompanying drawing explanation

Fig. 4 is that B in Fig. 3 is to partial enlarged drawing.
1. outward flange dish, 2. bearing outer ring, 3. retainer, 4. back-up rings, 5. left seal ring, 6. bearing inner race, 7. right seal ring in the drawings, 8. detains edge, a. steel ball.
Embodiment
In the existing ball hub bearing package assembly of Fig. 1, Fig. 2, outward flange dish 1 is sleeved on bearing outer ring 2 cylindrical, and bearing outer ring 2 is sleeved on and holds on inner ring 6; Be provided with corresponding biserial raceway between bearing outer ring 2 inner headed face with bearing inner race 6 periphery, in biserial raceway, be respectively equipped with retainer 3, retainer 3 is provided with steel ball a; Between two ends, raceway groove left and right between bearing inner race periphery and outer ring inner headed face, seal ring sealing 5 and seal ring sealing 7 are housed respectively; Flange plate 1 left end inner circle is provided with groove outside, back-up ring 4 is arranged in the groove in outward flange dish 1 left end inner circle, bearing outer ring 2 and bearing inner race 6 control outside in flange plate 1 inner circle by back-up ring 4, under the effect of outward flange 1 and bearing outer ring 2 interference fit and back-up ring 4, prevent bearing outer ring 2 and bearing inner race 6 from moving axially.
In the mode of execution shown in the utility model Fig. 3 and Fig. 4, riveting ball hub bearing in end face enters in the inner circle of outward flange dish 1 by bearing outer ring 2 riveting, and bearing outer ring 2 is sleeved on and holds on inner ring 6; Be provided with corresponding biserial raceway between bearing outer ring 2 inner headed face with bearing inner race 6 periphery, in biserial raceway, be respectively equipped with retainer 3, retainer 3 is provided with steel ball a; Between two ends, raceway groove left and right between bearing inner race periphery and outer ring inner headed face, seal ring 5 and seal ring 7 are housed respectively.
Bearing outer ring 2 riveting is entered in the inner circle of outward flange dish 1, bearing outer ring 2 and outward flange dish 1 interference fit, then by left end (front end) head of outward flange dish 1, riveting is on the end face of bearing outer ring 2, form button along 8, bearing outer ring 2 is closely controlled, outside in flange plate 1 inner circle, form an overall structure, prevent bearing outer ring 2 axial displacement.
The utility model, be on existing ball hub bearing architecture basics, remove check ring 4, outward flange dish and bearing outer ring are riveted, shape full overall structure, not only effectively can eliminate the axial displacement of bearing but also formed after entirety can the rigidity of lifting wheel hub unit.
