Description
Technical field
It the utility model is related to a kind of hub unit, more particularly to a kind of biserial ball hub bearing list of Novel spline structure
Member, hub unit are used for automobile.
Background technology
Hub-bearing unit is generally using in ring flange bore design involute inner spline structure.This structure is driving wheel
Hub-bearing unit, but this is complicated, wheel hub is drivingly connected position overall weight weight, and fuel economy is low；This wheel hub
Bearing unit driving moment is to be transferred to by axial splines from cage on hub bearing, and driving moment can disappear in conduction
Consumption；In driving torque, for spline to being connected to gap, transmission is ineffective；The common internal diameter of endoporus involute spline is in Φ 20- Φ
38, radius is small, and the driving torque of output is small, and axial splines are complex when being installed with drive shaft spline fitted.
Chinese patent CN200620108249.5, discloses a kind of automobile hub unit assembly, including mandrel, outer ring, inner ring,
First rolling element and the second rolling element, the outside of mandrel are furnished with raceway groove, and the inner side of outer ring is furnished with biserial raceway groove, outer ring and inner ring it
Between be clamped with the first rolling element, the second rolling element is clamped between outer ring and mandrel, inner ring is fixed in the core passed through inside it
On axis, the internal diameter of inner ring and the outside diameter of mandrel are interference fitted to be formed and are fixedly connected, and the end of mandrel uses spinning riveted construction, rotation
Pressure riveted construction is close to the large end face of inner ring.This structure is relative complex, and assembly precision is relatively low, and using effect does not go out
Color.
The content of the invention
The utility model mainly solves the deficiencies in the prior art, there is provided one kind solves the docking of traditional structure spline
Have that gap, installation are complicated, driving moment loss is big, output torque is small, the one of the problems such as component weight weight, fuel economy are low
The biserial ball hub bearing unit of kind Novel spline structure.
The above-mentioned technical problem of the utility model is mainly what is be addressed by following technical proposals：
A kind of biserial ball hub bearing unit of Novel spline structure, including ring flange, dress is equipped with the ring flange
Distribution, the outer wall of the ring flange left end are equipped with the inner ring of half built-in, are cased with outer ring outside the inner ring and ring flange, institute
Between the inner ring stated and outer ring, retainer is respectively equipped between ring flange and outer ring, steel ball, the method are equipped with the retainer
The left side wall of blue disk is rotation riveting plane, and the surface of the rotation riveting plane is equipped with continuously distributed spline, the spline outside
Footpath size is Φ 50- Φ 70, and the tooth a height of 5.5~6.8 of spline, the number of teeth of spline is 30~40, and the type face angle of spline is 30
~60 °.
Preferably, the width ecto-entad of the spline teeth groove is gradually reduced, the two side ends on the spline top
It is distributed respectively in arc-shaped.
Preferably, sealed between the ring flange and outer ring by outer side seal circle, between the inner ring and ring flange
Sealed by inner seal circle, the outer wall of the inner seal circle is equipped with Embedded magnetic circle.
Preferably, the left end of the outer ring is cased with protective cover.
Preferably, the top of the inner ring right end and the stitching portion of ring flange are in same level EDS maps, it is described
The edge of outer ring is equipped with two pairs of outer ring fixed angles being symmetric, and the edge of the ring flange is evenly distributed equipped with 5
Ring flange fixed angles, be respectively equipped with bolt hole in the outer ring fixed angles and ring flange fixed angles.
Operation principle：By the design of bearing spline at rotation riveting plane, driving company is easily installed, increases driving torque and mitigated
The weight of socket part position, because needing in rotation riveting plane machining spline, so optimization need to be designed to rotation riveting height and outside diameter.
By the design of bearing spline in the plane after revolving riveting, it is located at the internal spline at ring flange endoporus different from tradition, this
Kind design can obviously reduce splined connecting portion part gross weight；Since such a spline possesses what therefore the diameter of bigger can transmit
Torque wants greatly more, can be obviously improved the dynamic operation performance of automobile；Energy consumption is low and is more convenient for installing.
Optimization, increase rotation riveting fitting layer height are designed to the rotation riveting spot size for processing spline.In rotation riveting plane
Process spline.Product carries out spline processing after riveting is revolved in assembling, using high-precision milling equipment in rotation riveting plane.Because that need to revolve
Spline is processed in riveting plane, so to increase rotation riveting fitting layer height, riveting fitting intensity is revolved to meet to process after spline, is different from
The rotation riveting height of 3.5 traditional~5mm.
Therefore, the biserial ball hub bearing unit of a kind of Novel spline structure of the utility model, compact-sized, increase passes
Kinetic moment, reduce energy consumption, be easily installed.
