Abstract
The utility model discloses a kind of hub unit assemblies of sealing element externally-packed structure, including outer ring, inner ring, mandrel, back-pressure lid, steel ball, retainer, bolt and sealing element, the sealing element includes sealing element A and sealing element B, and the sealing element B is equipped with and the matched externally-packed structure in outer ring.Card structure in sealing element is changed to externally-packed structure by the utility model, reduces outer ring processing technology, improves processing efficiency.Outer ring process is combined into same size with fitted position.
Description
Technical field
The utility model is related to a kind of hub unit assemblies, and in particular to a kind of hub unit of sealing element externally-packed structure is total
At.
Background technology
Currently, hub bearing is to be applied at Automobile shaft improve accurately guide zero for load-bearing and for the rotation of wheel hub
Component bears axial load and bears radial load again, be the important component of carload and rotation.As people are to vapour
The attention of vehicle safety traffic, more stringent requirements are proposed to complete vehicle quality by each manufacturer and user, also requires hub unit
There is more good performance.Its service life thus is improved, the hub unit for manufacturing high-quality has become domestic each automobile
The common effort target of hub bearing manufacturing and processing enterprise.
In process, inside and outside two faces of outer ring are required to be finished, and have externally played mill ditch for existing outer ring
Supporting role when road, internally with sealing element mating reaction, schematic diagram after existing outer ring is installed with sealing element（As shown in Figure 3）,
But the inner surface of outer ring easy tos produce the problems such as folder deformation in process.Requirement on machining accuracy is high, is brought to manufacture craft
It is difficult.
Invention content
The technical problem to be solved by the utility model is to provide a kind of hub unit assemblies of sealing element externally-packed structure, will
Card structure is changed to externally-packed structure in sealing element, reduces outer ring processing technology, improves processing efficiency.
The utility model technical scheme applied to solve the technical problem is：A kind of hub unit of sealing element externally-packed structure
Assembly, including outer ring, inner ring, mandrel, back-pressure lid, steel ball, retainer, bolt and sealing element, the sealing element include sealing element A
It is equipped with and the matched externally-packed structure in outer ring with sealing element B, the sealing element B.
The utility model has the beneficial effects that:Card structure in sealing element is changed to externally-packed structure, outer ring is reduced and processes work
Skill improves processing efficiency.Outer ring process is combined into same size with fitted position.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 is the utility model embodiment outer ring and sealing element B mounting structure schematic diagrams.
Fig. 3 is prior art outer ring and sealing element mounting structure schematic diagram.
The utility model is described further below in conjunction with the accompanying drawings.
Specific implementation mode
As shown in Fig. 1, hub unit includes outer ring 1, inner ring 2, mandrel 3, back-pressure lid 4 and sealing element A5, steel ball 6, protects
Frame 7, sealing element B8, bolt 9 are held, the sealing element B is equipped with to be used to install with the matched externally-packed structure 10 in outer ring, the mandrel 3
Brake disc, bolt 9 is passed through for being connected and fixed mandrel and brake disc, the splined shaft of automobile chassis inside mandrel 3 on mandrel 3, band
The rotation of driving wheel tire.Two retainers 7 make steel ball 6 uniformly distributed on raceway, play the role of carrying and transmit rotation.It is each to keep
Frame 7 respectively installs 15 steel balls 6；Sealing element A5, back-pressure lid 4 and sealing element B8 make entire working position form a sealing
System, it is not affected with dust, prevent grease from outflowing.
When assembly, cleaning demagnetization processing is carried out to all components, is put into outer ring 1 after steel ball 6 is packed into retainer 7, it will
On sealing element B8 concora crush to outer ring, sealing element B8 is sealed using outsourcing seal form, as shown in Figure 2.Complete the above work
It will be placed on mandrel 3 equipped with the outer ring 1 of steel ball 6 and sealing element B8 after sequence, bolt 9 be pressed on mandrel 3.Finally by inner ring 2 and instead
Gland 4 and sealing element A5 are pressed into press on mandrel 3.
