The limitation of the utility model.
Fig. 1-Fig. 4 is a kind of water-proof hub bearing that the utility model embodiment provides, including inner ring 1, outer ring 2 and flange
Disk 3, the outer ring 2 are set on the ring flange 3, and the inner ring 1 is set between the outer ring 2 and ring flange 3, described outer
Be respectively arranged with one group of rolling element between circle 2 and ring flange 3, between the outer ring 2 and inner ring 1, the inner ring 1 and outer ring 2 it
Between, the sealing ring 4 of circular ring shape is both provided between outer ring 2 and ring flange 3, the sealing ring 4 is by shape memory alloy material system
Into, it is respectively present the first form and the second form at the first temperature and second temperature, it is coaxial in the outer circle of the sealing ring 4
It is provided with the outer rubber circle 41 of circular ring shape, is respectively arranged with and the sealing ring 4 on the outer wall of the inner ring 1 and ring flange 3
The groove of the corresponding circular ring shape of inner circle, the inner circle of each sealing ring 4 are connected to its corresponding described inner ring 1 or ring flange 3
On groove in, at a temperature of described first, there are gap between the outer rubber circle 41 and the inner wall of the outer ring 2, described
At a temperature of two, contradicted between the outer rubber circle 41 and the inner wall of the outer ring 2.
It is the existing common third generation by the hub bearing that inner ring 1, outer ring 2 and ring flange 3 are formed in above-mentioned technical proposal
Hub bearing, the connection relation between inner ring 1, outer ring 2 and ring flange 3 are：Outer ring 2 is set on ring flange 3, and inner ring 1 is arranged
Between outer ring 2 and ring flange 3, two circle rolling elements are set respectively so that outer between outer ring 2 and inner ring 1, outer ring 2 and ring flange 3
It can be relatively rotated between circle 2 and inner ring 1, outer ring 2 and ring flange 3, between outer ring 2 and inner ring 1, between outer ring 2 and ring flange 3
There are gap, during hub bearing use, common dirty such as water and dust may enter outer ring 2 and inner ring 1
Between, in the gap between outer ring 2 and ring flange 3, if things go on like this, its normal use can be influenced, shorten the service life of hub bearing,
The sealing ring 4 of circular ring shape is provided in this programme between outer ring 2 and inner ring 1, to prevent water or dust enters outer ring 2 and interior
Between circle 1, the sealing ring 4 of circular ring shape between outer ring 2 and inner ring 1 is set, and circle is coaxially arranged in the outer circle of sealing ring 4
The outer rubber circle 41 of annular, and the groove equipped with circular ring shape corresponding with the inner circle of sealing ring 4 on the outer wall of inner ring 1, will be close
The inner circle of seal 4 is connected in the groove of circular ring shape, and due to hub bearing at work, due to rubbing action, its temperature can increase
Add, so making sealing ring 4 using shape memory alloy material, first is respectively present at the first temperature and second temperature at it
Ultimum Ti, nickel titanium copper memory alloy, iron-based memory conjunction may be used in form and the second form, shape memory alloy material
Gold, copper-based memory alloy and other materials with memory function etc., the martensite reverse transformation of memorial alloy complete temperature Af's
Design value is generally between 40-50 DEG C, so second temperature is the normal working temperature of hub bearing, in the range of 40-50 DEG C,
First temperature is then less than 40 DEG C, i.e., under room temperature, there are gap between the inner wall of outer rubber circle 41 and the outer ring 2, in outer rubber
Lubricating oil is injected on the outside of cushion rubber 41, you can gap is blocked by lubricating oil, prevents water and dust from passing through, and with wheel hub
The rotation of bearing, and the lubricating oil that rotation is be easy to cause in gap is thrown out of, so being made of shape memory alloy material close
Seal 4 after temperature raising, enters the second form, volume becomes larger so that outer rubber circle 41 is interior with outer ring 2 by the first form
Contradicted between wall, thus can will be completely separated between outer ring 2 and inner ring 1 by sealing ring 4, simultaneously because outer rubber circle 41
With elasticity, can be stretched, and do not interfere with its normal work with the increase of 4 volume of sealing ring.
In the water-proof hub bearing, rolling element described in every group includes multiple along the circumferential equidistant of the outer ring 2
Spaced steel ball 5.
In another technical solution, one group of steel is respectively provided between outer ring 2 and inner ring 1, between outer ring 2 and ring flange 3
Ball 5, every group of steel ball 5 are arranged at intervals at equal intervals along the circumferential of outer ring 2, and steel ball 5 can also use cylindrical roller, circular cone to roll
Son, needle roller etc., but 5 intensity of steel ball is good, easy processing, and can make rolling element by steel ball 5 along arbitrary directional rolling, is ensureing to roll
The situation of the normal performance of kinetoplast, can be effectively reduced difficulty of processing and material cost.
In the water-proof hub bearing, the fixed steel ball 5 is respectively provided on the inner ring 1 and ring flange 3
Retainer 6.
In another technical solution, in order to ensure the normal rolling of steel ball 5, by distinguishing on inner ring 1 and ring flange 3
Retainer 6 is set, and rubber can be used in retainer 6, plastic or other material makes, and retainer 6 partly wraps up all or part of steel ball
5, and the bearing parts moved therewith, steel ball 5 is isolated, usually also guides steel ball 5 and hold it in bearing.
In the water-proof hub bearing, the retainer 6 is made of rubber material.
In another technical solution, retainer 6 is made of rubber material, since rubber is with the high-elastic of reversible deformation
Property polymer material, in the high resilience equal at use temperature of room temperature and hub bearing, can be generated under the external force effect of very little
Compared with large deformation, remove resilient after external force, allow for retainer 6 in this way while the position for limiting steel ball 5, when its by
When acting on to external force, it can restore to the original state to make retainer 6 in the case where being acted on by external force after external force disappearance, moreover it is possible to
It keeps stablizing, limitation is played to steel ball 5.
In the water-proof hub bearing, the outer rubber circle 41 of the sealing ring 4 on the inner ring 1 is far from the flange
Multiple pull rods 42 are provided on the side of disk 3, to take the sealing ring 4 from the inner ring 1 by multiple pull rods 42
Under.
In another technical solution, when inner ring 1 and the connection of outer ring 2, if desired sealing ring 4 is removed from inner ring 1
When, it only need to be by pulling the pull rod 42 on outer rubber circle 41, you can easily sealing ring 4 is removed from inner ring 1, and by sealing ring
4 be mounted on inner ring 1 on when, also only need to push away pull rod 42 between outer ring 2 and inner ring 1.
In the water-proof hub bearing, the pull rod 42 is made of rubber material.
In another technical solution, since rubber is the strong flexible polymer material with reversible deformation, in room temperature and
The high resilience equal at use temperature of hub bearing can generate compared with large deformation under the external force effect of very little, remove energy after external force
It restores to the original state, pull rod 42 is made of rubber material can extend its service life, while outer rubber circle 41 is also made of rubber, outer rubber
Cushion rubber 41 and multiple pull rods 42 thereon can be integrally formed making.
Although the embodiment of the utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modification is easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
Specific details and embodiment shown and described herein are not limited to novel.
