Description
Technical field
The utility model relates to a kind of bearing, especially relates to a kind of angular contact ball bearing.
Background technique
As the automotive hub bearing, its reliability directly affects personal safety, is very harsh to the quality requirement of automobile hub bearing therefore.
The Main Function of automobile hub bearing is load-bearing and for the rotation of wheel hub provides accurate guiding, and it not only bears thrust load but also bear radial load, also has impulsive load, is very important component.Traditional used for automobile wheels bearing is to be supported the use by two cover tapered roller bearings or angular contact ball bearing, and the adjustment of the installation of bearing, oiling, sealing and play is all carried out at auto production line.This structure is so that its, poor reliability high in auto producer assembling difficulty, cost, and automobile is when maintenace point is safeguarded, also need to bearing clean, oiling and adjustment.Hub-bearing unit is to grow up on the basis of standard angle contact ball bearing and tapered roller bearing, it is made two sleeves and is integrated, have the assembling performance good, can omit play adjustment, lightweight, compact structure, load bearing capacity large, for stuffing box bearing can pack in advance lubricating grease, omit external hub and seal and avoid the advantage such as maintenance.
Supporting for automobile production producer as automobile hub bearing supplier, always by the main famous brand monopolization in the world, some low-end markets or after market can only be done by domestic hub bearing manufacturing firm, study carefully its more this reason be exactly the breakthrough that a lot of key technology domestic manufacturer of hub bearing production all is difficult to have matter always.
A kind of biserial angular contact ball hub bearing is wherein just arranged, and main failure forms has that working surface peels off, retainer damage, noise etc., by analyzing, causes the reason of these inefficacies to mainly contain:
Two row steel ball rotational speeies are inconsistent, retainer to integral type has produced a shearing force, cause retainer to damage, in addition because rotating speed inconsistent, and retainer is integral type, must cause the steel ball of the slow row of rotating speed can produce certain slip, thereby cause the frictional heating of working surface to peel off; This some producer is designed to the split formula with retainer, but also there are a lot of defectives in this, the structure space restriction of hub bearing, the two ditch distance of positions can't hold split type retainer from limited, even some holds reluctantly, but its intensity is very low, is subjected to slight active force will produce fracture; Secondly, split type retainer can not effectively be adjusted the distance of two row steel balls, easily makes bearing produce unbalance loading, causes working surface to peel off, final bearing failure.
The model utility content
The purpose of this utility model is exactly to provide a kind of bearing reliability and the automobile in life-span biserial angular contact ball hub bearing of greatly having improved for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of angular contact ball bearing, it is characterized in that, comprise inner ring, outer ring, seal ring, a plurality of steel ball and retainer, consist of the biserial raceway groove suitable with steel ball between described inner ring and the outer ring, described retainer is evenly distributed on steel ball in the biserial raceway groove, and described seal ring is located at the edge side between outer ring and the inner ring.
Described retainer is provided with two, and each retainer back is provided with a plurality of V-shaped grooves, two back-to-back installations of retainer, and its V-type groove is mutually arranged in a crossed manner.
Described V-shaped groove is consistent with retainer pocket hole number.
Described inner ring is fixedly formed by snap close by two interior coil units.
The end face of described two interior coil units is provided with for the groove of placing snap close.
The inner ring two ditches footpath of this bearing is poor and two ditches footpath in outer ring is poor all less than 0.004mm, and inner ring ditch curvature is 0.51～0.52, and outer ring channel curvature is 0.52～0.53.
The difference in internal diameters of this bearing is less than 1/4 of the id tolerance band, and contact angle difference is less than 1 °.
Described outer ring is the outer ring that carbon alloy steel is made, and it is provided with flange, and this flange and external diameter transition position adopt the least radius design.
Compared with prior art, the utlity model has following advantage:
1, adopt split staggered form retainer, the first, solved because the inner space restriction can't be used the bottleneck of split type retainer, and greatly improve the intensity of retainer; The second, solved two row steel balls rotations inconsistent, the impact that retainer is produced shearing force; The 3rd, so that remain relatively evenly distribution between the two row steel balls, the equilibrium that has improved load avoids stress to concentrate; The 4th, when bearing is subjected to axial force or tilting moment, can automatically adjust the distance of two row steel balls, keep two row steel balls in reasonably distance work; This shows and adopt split staggered form retainer, greatly improved bearing reliability and life-span.
2, adopt the Internal and external cycle ditch footpath difference and special ditch curvature of design after, guaranteed the conformity of two row steel balls when rotation speed of bearing, thereby reduced the collapsing force that two row steel ball speed discrepancies produce retainer, improved the working life of retainer, in addition, special ditch footpath is poor, when having guaranteed bearing operation, the conformity of channel wire speed has reduced the infringement of steel ball sliding friction to working surface, has greatly improved bearing life.
3, adopt design difference in internal diameters and contact angle difference after, guaranteed bearing after installing and using, two row steel balls are stressed consistent, avoided the phenomenon of partial load, further improved bearing working life.
4, the medium carbon alloy steel material is adopted in the outer ring, compares with the existing carbon steel that uses, and toughness significantly improves, and outer ring flange and the design of external diameter transition position employing least radius, has promoted the rigidity of flange, has therefore greatly improved the resistance to shock loads of bearing.
