Description
Technical field
The utility model relates to the fields of the bearing unit mechanism of automobile, and in particular to a kind of band powder metallurgy gear ring wheel hub
Unit.
Background technique
Automotive hub causes its quality and geometric center due to the detraction in the error or use process of the manufacturing
It is not quite identical, but there is deviation slightly, cumulative attrition and safety inspection hidden danger are caused to axle, it is therefore desirable to periodically
Wheel hub is adjusted, although at present have detection device can be accurately detected whether eccentric angle be it is how many, adjust get up ten
It is point loaded down with trivial details, while increasing cost.
The bearing unit structure used currently on the market for vehicle, it is to use single-row tapered roller or ball bearing in pairs.
Chinese patent discloses a kind of automobile drive bridge speed differientiator (Authorization Notice No.: CN 200620108249), and it discloses a kind of vapour
The outside of wheel hub unit assembly, including mandrel, outer ring, inner ring, the first rolling element and the second rolling element, mandrel is furnished with channel,
Rolling element is clamped between outer ring and inner ring, inner ring is fixed on the mandrel passed through inside it, the internal diameter of inner ring and mandrel
Outer diameter is interference fitted to be formed and be fixedly connected, and the end of mandrel uses spinning riveted construction, and spinning riveted construction is close to the big of inner ring
End face.But this bearing wheel hub unit, manufacture it is more complicated, and if replace a hub unit need to dismantle, operate
Come very loaded down with trivial details, while increasing cost.
That there are manufacturing costs is excessively high for the prior art, in actual use, operates loaded down with trivial details, is also easy to produce teeth portion and the feelings such as wears, kill
Condition, and if replace a bearing unit and need to dismantle entire components, operate it is very loaded down with trivial details, while increase after-sale service at
The technical problem of this grade.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of band powder metallurgy gear ring wheel
Hub unit.
The purpose of this utility model is completed by following technical solution: this band powder metallurgy gear ring wheel hub list
Member mainly includes outer ring, gear ring, seal assembly, steel ball, retainer, inner ring, dustproof cover, bolt, and the inner cavity of outer ring, which is equipped with, to keep
Frame, outer ring outer diameter are set with rack gear, and four threaded holes in outer ring assemble bolt, and outer ring front end is equipped with seal assembly, seal assembly with
Inner ring is connected, and is connected outside inner ring with retainer, and retainer is equipped with steel ball.
The outer ring is externally provided with flange, is set on outer ring there are four threaded hole, outer ring is also equipped with convex block, and convex block can increase
The intensity of entire bearing unit, so that the intensity covered on when connecting with outer ring outside is stronger.
The gear ring is powdered metallurgical material, has the features such as heat-resist, high temperature resistant.
The retainer is equipped with interior retainer and outer retainer.
The utility model has the following beneficial effects:
1, the utility model is applied to the sealing mechanism of automobile hub unit, is equipped with gear ring sealing element, simple and compact for structure,
Installation accuracy is high, good seal performance, and performance is stablized, and integrated level is high, and at low cost.
Detailed description of the invention
Fig. 1 is the structure sectional view of the utility model.
Fig. 2 is the structural front view of the utility model.
Description of symbols: outer ring 1, gear ring 2, seal assembly 3, steel ball 4, retainer 5, inner ring 6, dustproof cover 7, bolt 8.
Specific embodiment
Detailed introduction is done to the utility model below in conjunction with attached drawing:
As shown in the picture, this band powder metallurgy gear ring hub unit, mainly include outer ring 1, gear ring 2, seal assembly 3,
Steel ball 4, retainer 5, inner ring 6, dustproof cover 7, bolt 8, the inner cavity of outer ring 1 are equipped with retainer 5, and 1 outer diameter of outer ring is set with rack gear
2, the threaded hole of outer ring 1 four assembles bolt 8, and 1 front end of outer ring is equipped with seal assembly 3, and seal assembly 3 is connected with inner ring 6, inner ring 6
Outside is connected with retainer 5, and retainer 5 is equipped with steel ball 4.
The outer ring 1 is externally provided with flange, is set on outer ring 1 there are four threaded hole, and also equipped with convex block, convex block can be with for outer ring 1
Increase the intensity of entire bearing unit, so that the intensity covered on when connecting with outer ring 1 outside is stronger.
The gear ring 2 is powdered metallurgical material, has the features such as heat-resist, high temperature resistant.
The retainer 5 is equipped with interior retainer and outer retainer.
It is understood that it will be understood by those skilled in the art that the technical solution of the utility model and utility model structure
Think of is subject to equivalent substitution or change all and should belong to the protection scope of the utility model the attached claims.
