Between be equipped with cricoid first raceway groove and the second raceway groove, the first raceway groove is in ring flange end one side, and the second raceway groove is in ring flange root
One side is equipped with ball in the first raceway groove and the second raceway groove, and outer ring is rolled by two rows of balls with ring flange and inner ring and connected, interior
Retainer is mounted in the first raceway groove, and outer retainer is mounted in the second raceway groove, and the diameter of the second raceway groove is more than the first raceway groove
Diameter, the ball in the second raceway groove is more than the ball in the first raceway groove；Ring flange end is equipped with the crimping with ring flange one, volume
While it is close to one end of inner ring；Equipped with 18 balls in first raceway groove, the second raceway groove is interior to be equipped with 20 balls；Speed is additionally provided with outside inner ring
Inductor is spent, speed sensor includes magnetic induction head and alloy tooth annulus.Chinese patent also discloses a kind of automotive wheels hub axle
Bearing unit（Authorization Notice No.：CN201401445）, including ring flange inner ring, flange plate outer ring, inside race, ball and holding
Frame is set on flange plate outer ring inner surface there are two outer raceway, is respectively provided with and outer raceway on ring flange inner ring and inside race outer surface
Corresponding interior raceway, ball are placed in retainer inscribe between interior raceway and outer raceway, on ring flange inner ring outer surface
With annular groove and step surface, annular retaining ring is equipped in groove, inside race end face is resisted against on annular retaining ring, other end
It is resisted against on step surface.But these automobile hub units generally can only forge a blind hole in forging, so another is blind
Hole must could be completed by follow-up Vehicle Processing, and process is more numerous and diverse, and intensity is poor, and positioning is more inaccurate.
Utility model content
The utility model is to provide a kind of double blinding hole riveted hub-bearing unit, mainly solves the prior art and is deposited
Automobile hub unit generally forging when can only forge a blind hole, so another blind hole must pass through follow-up Vehicle Processing
It could complete, process is more numerous and diverse, and intensity is poor, positions the technical issues of more inaccurate etc..
The above-mentioned technical problem of the utility model is mainly what is be addressed by following technical proposals：
The double blinding hole riveted hub unit of the utility model, including flange body, in one end of the flange body
Portion is equipped with forging big-diameter blind hole, and forging big-diameter blind hole includes the circular platform type bottom surface of external horn mouth and inside, flange body
The other end is internally provided with forging small blind hole, forges the bottom surface of small blind hole as arc groove, and the outer circle of arc groove is equipped with arc transition slot.
The utility model sets forging big-diameter blind hole, forging small blind hole simultaneously, so processes more convenient, it is possible to reduce follow-up Vehicle Processing.
It can ensure the processing of forging small blind hole using arc transition slot, and material can be reduced.
Preferably, the outer surface of the flange body is equipped with multi-stage stairs, the corner of step is equipped with fillet surface.It is logical
The installation accuracy of flange body can be ensured by crossing step, and fillet surface can prevent step from wearing other components in assembling.
Preferably, it is equipped with arc-shaped transitional surface, circle between horn mouth and the circular platform type bottom surface forged in big-diameter blind hole
Arc transition face is equipped with caulking groove, is equipped in caulking groove and strengthens alloy-layer, and the section for strengthening alloy-layer is blade type.
Preferably, be provided with adjustment tank on the end face of the flange body, gripping block is equipped in adjustment tank, in compact heap
End is equipped with compression spring.By gripping block and compression spring can the end face of flange body there is cushion effect in assembling, ensure that peace
Fill precision.
Therefore, the utility model processes double forging blind holes simultaneously, it is possible to reduce and follow-up Vehicle Processing, process is relatively simple,
Intensity is higher, and positioning is more accurate, simple and reasonable for structure.
